Gas attack in World War II. Use of gases in the First World War

The first gas attack in World War I, in short, was carried out by the French. But the German military was the first to use toxic substances.
For various reasons, in particular the use of new types of weapons, the First World War, which was planned to end in a few months, quickly escalated into a trench conflict. Such hostilities could continue for as long as desired. In order to somehow change the situation and lure the enemy out of the trenches and break through the front, all kinds of chemical weapons began to be used.
It was the gases that became one of the reasons for the huge number of casualties in the First World War.

First experience

Already in August 1914, almost in the first days of the war, the French in one of the battles used grenades filled with ethyl bromoacetate (tear gas). They did not cause poisoning, but were capable of disorienting the enemy for some time. In fact, this was the first military gas attack.
After supplies of this gas were depleted, French troops began using chloroacetate.
The Germans, who very quickly adopted advanced experience and what could contribute to the implementation of their plans, adopted this method of fighting the enemy. In October of the same year, they tried to use shells with a chemical irritant against the British military near the village of Neuve Chapelle. But the low concentration of the substance in the shells did not give the expected effect.

From irritating to poisonous

April 22, 1915. This day, in short, went down in history as one of the darkest days of the First World War. It was then that German troops carried out the first massive gas attack using not an irritant, but a poisonous substance. Now their goal was not to disorient and immobilize the enemy, but to destroy him.
It happened on the banks of the Ypres River. 168 tons of chlorine were released by the German military into the air towards the location of the French troops. The poisonous greenish cloud, followed by German soldiers in special gauze bandages, terrified the French-English army. Many rushed to run, giving up their positions without a fight. Others, inhaling the poisoned air, fell dead. As a result, more than 15 thousand people were injured that day, 5 thousand of whom died, and a gap more than 3 km wide was formed in the front. True, the Germans were never able to take advantage of their advantage. Afraid to attack, having no reserves, they allowed the British and French to fill the gap again.
After this, the Germans repeatedly tried to repeat their such a successful first experience. However, none of the subsequent gas attacks brought such an effect and so many casualties, since now all troops were supplied with individual means of protection against gases.
In response to Germany's actions at Ypres, the entire world community immediately expressed its protest, but it was no longer possible to stop the use of gases.
On the Eastern Front, against the Russian army, the Germans also did not fail to use their new weapons. This happened on the Ravka River. As a result of the gas attack, about 8 thousand soldiers of the Russian imperial army were poisoned here, more than a quarter of them died from poisoning in the next 24 hours after the attack.
It is noteworthy that, having first sharply condemned Germany, after some time almost all Entente countries began to use chemical agents.

The rapid development of the science of chemistry at the end of the 19th century made it possible to create and use the first weapon of mass destruction in history - poisonous gases. Despite this, and despite the expressed intention of many governments to humanize warfare, chemical weapons were not banned before the First World War. In 1899, at the First Hague Conference, a declaration was adopted that stated the non-use of projectiles containing toxic and harmful substances. But the declaration is not a convention; everything that is written in it is advisory in nature.

World War I

Formally, at first the countries that signed this declaration did not violate it. Tear gases were delivered to the battlefield not in shells, but in throwing grenades, or sprayed from cylinders. The first use of a deadly asphyxiating gas - chlorine - by the Germans near Ypres on April 22, 1915, was also made from cylinders. Germany did the same in subsequent similar cases. The Germans first used chlorine against the Russian army on August 6, 1915 at the Osovets fortress.

Subsequently, no one paid attention to the Hague Declaration and used shells and mines with toxic substances, and asphyxiating gases were invented more and more efficiently and deadly. The Entente considered itself free from compliance with international norms of war, in response to their violation by Germany.

Upon receiving information about the use of toxic substances by the Germans on the Western Front, Russia also began producing chemical weapons in the summer of 1915. Chemical shells for three-inch guns were first filled with chlorine, later with chloropicrin and phosgene (the method for synthesizing the latter was learned from the French).

The first large-scale use of shells with toxic substances by Russian troops took place on June 4, 1916 during artillery preparation before the Brusilov breakthrough on the Southwestern Front. Spraying gases from cylinders was also used. The use of chemical weapons also became possible thanks to the supply of sufficient gas masks to Russian troops. The Russian command highly appreciated the effectiveness of the chemical attack.

Between world wars

However, the First World War as a whole showed the limitations of chemical weapons if the enemy had means of defense. The use of toxic substances was also restrained by the danger of their retaliatory use by the enemy. Therefore, between the two world wars they were used only where the enemy had neither protective equipment nor chemical weapons. Thus, chemical warfare agents were used by the Red Army in 1921 (there is evidence that in 1930-1932) to suppress peasant uprisings against Soviet power, as well as by the army of fascist Italy during the aggression in Ethiopia in 1935-1936.

Possession of chemical weapons after the First World War was considered the main guarantee that they would be afraid to use such weapons against this country. The situation with chemical warfare agents is the same as with nuclear weapons after World War II - they served as a means of intimidation and deterrence.

Back in the 1920s, scientists calculated that the accumulated reserves of chemical munitions would be enough to poison the entire population of the planet several times over. Same thing since the 1960s. they began to assert about the nuclear weapons that were available at that time. Both, however, were not untrue. Therefore, back in 1925 in Geneva, many states, including the USSR, signed a protocol banning the use of chemical weapons. But since the experience of the First World War showed that in such cases little regard is paid to conventions and prohibitions, the great powers continued to build up their chemical arsenals.

Fear of retaliation

However, in World War II, for fear of a similar response, chemical munitions were not used directly at the front against active enemy forces, nor in aerial bombing of targets behind enemy lines.

However, this did not exclude individual cases of the use of toxic substances against an irregular enemy, as well as the use of non-combat chemicals for military purposes. According to some reports, the Germans used poisonous gases to destroy the partisans who resisted in the Adzhimushkay quarries in Kerch. During some anti-partisan operations in Belarus, the Germans sprayed substances over the forests that served as partisan strongholds that caused leaves and pine needles to fall, so that partisan bases could be easier to detect from the air.

The legend of the poisoned fields of the Smolensk region

The possible use of chemical weapons by the Red Army during the Great Patriotic War is the subject of sensational speculation. Officially, the Russian authorities deny such use. The presence of the “secret” stamp on many documents related to the war multiplies monstrous rumors and “revelations.”

Among the “searchers” for artifacts of the Second World War, there have been legends for decades about huge mutant insects living in fields where mustard gas was supposedly generously sprayed in the fall of 1941, during the retreat of the Red Army. It is alleged that many hectares of land in the Smolensk and Kalinin (now Tver) regions, especially in the Vyazma and Nelidovo region, were contaminated with mustard gas.

Theoretically, the use of a toxic substance is possible. Mustard gas can create a dangerous concentration when evaporating from an open area, as well as in a condensed state (at temperatures below plus 14 degrees) when applied to an object with which an unprotected area of ​​skin comes into contact. Poisoning does not occur immediately, but only after several hours, or even days. A military unit, having passed through the place where mustard gas was sprayed, will not be able to immediately give an alarm signal to its other troops, but will inevitably be cut off from the battle after some time.

However, there are no clear publications on the topic of deliberate contamination of the area with mustard gas during the retreat of Soviet troops near Moscow. It can be assumed that if such cases had occurred, and German troops had actually encountered the poisoning of the area, then Nazi propaganda would not have failed to inflate this event as evidence of the use of prohibited means of warfare by the Bolsheviks. Most likely, the legend about “fields flooded with mustard gas” was born from such a real fact as the careless disposal of spent chemical ammunition, which constantly took place in the USSR throughout the 1920-1930s. Bombs, shells and cylinders with toxic substances buried then are still found in many places.

By mid-spring 1915, each of the countries participating in the First World War sought to pull the advantage to its side. So Germany, which terrorized its enemies from the sky, from under water and on land, tried to find an optimal, but not entirely original solution, planning to use chemical weapons - chlorine - against the adversaries. The Germans borrowed this idea from the French, who at the beginning of 1914 tried to use tear gas as a weapon. At the beginning of 1915, the Germans also tried to do this, who quickly realized that irritating gases on the field were a very ineffective thing.

Therefore, the German army resorted to the help of the future Nobel laureate in chemistry Fritz Haber, who developed methods for using protection against such gases and methods for using them in combat.

Haber was a great patriot of Germany and even converted from Judaism to Christianity to show his love for the country.

The German army decided to use poisonous gas - chlorine - for the first time on April 22, 1915 during the battle near the Ypres River. Then the military sprayed about 168 tons of chlorine from 5,730 cylinders, each of which weighed about 40 kg. At the same time, Germany violated the Convention on the Laws and Customs of War on Land, signed in 1907 in The Hague, one of the clauses of which stated that “it is prohibited to use poison or poisoned weapons against the enemy.” It is worth noting that Germany at that time tended to violate various international agreements and agreements: in 1915, it waged “unrestricted submarine warfare” - German submarines sank civilian ships contrary to the Hague and Geneva Conventions.

“We couldn't believe our eyes. The greenish-gray cloud, descending on them, turned yellow as it spread and scorched everything in its path that it touched, causing the plants to die. French soldiers staggered among us, blinded, coughing, breathing heavily, with faces dark purple, silent from suffering, and behind them in the gas-poisoned trenches remained, as we learned, hundreds of their dying comrades,” one recalled the incident. of the British soldiers who observed the mustard gas attack from the side.

As a result of the gas attack, about 6 thousand people were killed by the French and British. At the same time, the Germans also suffered, on whom, due to the changed wind, part of the gas they sprayed was blown away.

However, it was not possible to achieve the main goal and break through the German front line.

Among those who took part in the battle was the young corporal Adolf Hitler. True, he was located 10 km from the place where the gas was sprayed. On this day he saved his wounded comrade, for which he was subsequently awarded the Iron Cross. Moreover, he was only recently transferred from one regiment to another, which saved him from possible death.

Subsequently, Germany began using artillery shells containing phosgene, a gas for which there is no antidote and which, in sufficient concentration, causes death. Fritz Haber, whose wife committed suicide after receiving news from Ypres, continued to actively participate in the development: she could not bear the fact that her husband became the architect of so many deaths. Being a chemist by training, she appreciated the nightmare that her husband helped create.

The German scientist did not stop there: under his leadership, the toxic substance “Zyklon B” was created, which was subsequently used for the massacres of concentration camp prisoners during the Second World War.

In 1918, the researcher even received the Nobel Prize in Chemistry, although he had a rather controversial reputation. However, he never hid the fact that he was absolutely confident in what he was doing. But Haber’s patriotism and his Jewish origin played a cruel joke on the scientist: in 1933, he was forced to flee Nazi Germany to Great Britain. A year later he died of a heart attack.

According to rough estimates by historians, at least 1.3 million people suffered from chemical weapons during the First World War. All the main theaters of the Great War became, in fact, the largest testing ground for weapons of mass destruction in real conditions in the history of mankind. The international community began to think about the danger of such a development of events at the end of the 19th century, trying to introduce restrictions on the use of poison gases through a convention. But as soon as one of the countries, namely Germany, broke this taboo, all the others, including Russia, joined the chemical arms race with no less zeal.

In the material “Russian Planet” I suggest you read about how it began and why the first gas attacks were never noticed by humanity.

The first gas is lumpy


On October 27, 1914, at the very beginning of the First World War, the Germans fired improved shrapnel shells at the French near the village of Neuve Chapelle in the outskirts of Lille. In the glass of such a projectile, the space between the shrapnel bullets was filled with dianisidine sulfate, which irritates the mucous membranes of the eyes and nose. 3 thousand of these shells allowed the Germans to capture a small village on the northern border of France, but the damaging effect of what would now be called “tear gas” turned out to be small. As a result, disappointed German generals decided to abandon the production of “innovative” shells with insufficient lethal effect, since even Germany’s developed industry did not have time to cope with the monstrous needs of the fronts for conventional ammunition.

In fact, humanity then did not notice this first fact of the new “chemical war”. Against the backdrop of unexpectedly high losses from conventional weapons, tears from the soldiers’ eyes did not seem dangerous.

However, the leaders of the Second Reich did not stop experiments with combat chemicals. Just three months later, on January 31, 1915, already on the Eastern Front, German troops, trying to break through to Warsaw, near the village of Bolimov, fired at Russian positions with improved gas ammunition. That day, 18 thousand 150-mm shells containing 63 tons of xylylbromide fell on the positions of the 6th Corps of the 2nd Russian Army. But this substance was more of a tear-producing agent than a poisonous one. Moreover, the severe frosts that prevailed in those days negated its effectiveness - the liquid sprayed by exploding shells in the cold did not evaporate or turn into gas, its irritating effect turned out to be insufficient. The first chemical attack on Russian troops was also unsuccessful.

The Russian command, however, paid attention to it. On March 4, 1915, from the Main Artillery Directorate of the General Staff, Grand Duke Nikolai Nikolaevich, then the commander-in-chief of the Russian Imperial Army, received a proposal to begin experiments with shells filled with toxic substances. A few days later, the Grand Duke’s secretaries replied that “the Supreme Commander-in-Chief has a negative attitude towards the use of chemical shells.”

Formally, the uncle of the last tsar was right in this case - the Russian army was sorely lacking conventional shells in order to divert the already insufficient industrial forces to the production of a new type of ammunition of dubious effectiveness. But military technology developed rapidly during the Great Years. And by the spring of 1915, the “gloomy Teutonic genius” showed the world truly deadly chemistry, which horrified everyone.

Nobel laureates killed near Ypres

The first effective gas attack was launched in April 1915 near the Belgian town of Ypres, where the Germans used chlorine released from cylinders against the British and French. At the attack front of 6 kilometers, 6 thousand gas cylinders filled with 180 tons of gas were installed. It is curious that half of these cylinders were of civilian origin - the German army collected them throughout Germany and occupied Belgium.

The cylinders were placed in specially equipped trenches, combined into “gas batteries” of 20 pieces each. Burying them and equipping all positions for a gas attack was completed on April 11, but the Germans had to wait for more than a week for favorable winds. It blew in the right direction only at 5 pm on April 22, 1915.

Within 5 minutes, the “gas batteries” released 168 tons of chlorine. A yellow-green cloud covered the French trenches, and the gas affected mainly the soldiers of the “colored division” that had just arrived at the front from the French colonies in Africa.

Chlorine caused laryngeal spasms and pulmonary edema. The troops did not yet have any means of protection against gas; no one even knew how to defend themselves and escape from such an attack. Therefore, the soldiers who remained in their positions suffered less than those who fled, since every movement increased the effect of the gas. Because chlorine is heavier than air and accumulates near the ground, those soldiers who stood under fire suffered less than those who lay or sat at the bottom of the trench. The worst victims were the wounded lying on the ground or on stretchers, and people moving to the rear along with the cloud of gas. In total, almost 15 thousand soldiers were poisoned, of which about 5 thousand died.

It is significant that the German infantry, advancing after the chlorine cloud, also suffered losses. And if the gas attack itself was a success, causing panic and even the flight of French colonial units, then the German attack itself was almost a failure, and progress was minimal. The front breakthrough that the German generals were counting on did not happen. The German infantrymen themselves were openly afraid to move forward through the contaminated area. Later, German soldiers captured in this area told the British that the gas caused sharp pain to their eyes when they occupied the trenches left behind by the fleeing French.

The impression of the tragedy at Ypres was aggravated by the fact that the Allied command was warned at the beginning of April 1915 about the use of new weapons - a defector said that the Germans were going to poison the enemy with a cloud of gas, and that “cylinders with gas” were already installed in the trenches. But the French and English generals then only shrugged it off - the information was included in the intelligence reports of the headquarters, but was classified as “untrustworthy information.”

The psychological impact of the first effective chemical attack was even greater. The troops, who then had no protection from the new type of weapon, were struck by a real “gas fear”, and the slightest rumor of the start of such an attack caused general panic.

Representatives of the Entente immediately accused the Germans of violating the Hague Convention, since Germany in 1899 in The Hague at the 1st Disarmament Conference, among other countries, signed the declaration “On the non-use of projectiles whose sole purpose is to distribute asphyxiating or harmful gases.” However, using the same wording, Berlin responded that the convention prohibits only gas shells, and not any use of gases for military purposes. After that, in fact, no one remembered the convention anymore.

It is worth noting that chlorine was chosen as the first chemical weapon for completely practical reasons. In peaceful life, it was then widely used to produce bleach, hydrochloric acid, paints, medicines and a host of other products. The technology for its production was well studied, so obtaining this gas in large quantities was not difficult.

The organization of the gas attack near Ypres was led by German chemists from the Kaiser Wilhelm Institute in Berlin - Fritz Haber, James Frank, Gustav Hertz and Otto Hahn. European civilization of the 20th century is best characterized by the fact that all of them subsequently received Nobel Prizes for various scientific achievements of an exclusively peaceful nature. It is noteworthy that the creators of chemical weapons themselves did not believe that they were doing anything terrible or even simply wrong. Fritz Haber, for example, claimed that he had always been an ideological opponent of the war, but when it began, he was forced to work for the good of his homeland. Haber categorically denied accusations of creating inhumane weapons of mass destruction, considering such reasoning to be demagoguery - in response, he usually stated that death in any case is death, regardless of what exactly caused it.

“They showed more curiosity than anxiety”

Immediately after the “success” at Ypres, the Germans carried out several more gas attacks on the Western Front in April-May 1915. For the Eastern Front, the time for the first “gas attack” came at the end of May. The operation was again carried out near Warsaw near the village of Bolimov, where the first unsuccessful experiment with chemical shells on the Russian front took place in January. This time, 12 thousand chlorine cylinders were prepared over a 12-kilometer area.

On the night of May 31, 1915, at 3:20 a.m., the Germans released chlorine. Units of two Russian divisions - the 55th and 14th Siberian divisions - came under the gas attack. Reconnaissance on this section of the front was then commanded by Lieutenant Colonel Alexander DeLazari; he later described that fateful morning as follows: “Complete surprise and unpreparedness led to the fact that the soldiers showed more surprise and curiosity at the appearance of a gas cloud than alarm. Mistaking the gas cloud to camouflage the attack, Russian troops strengthened the forward trenches and brought up reserves. Soon the trenches were filled with corpses and dying people.”

In two Russian divisions, almost 9,038 people were poisoned, of whom 1,183 died. The gas concentration was such that, as an eyewitness wrote, chlorine “formed gas swamps in the lowlands, destroying spring and clover seedlings along the way” - the grass and leaves changed color from the gas, turned yellow and died along with the people.

As at Ypres, despite the tactical success of the attack, the Germans were unable to develop it into a breakthrough of the front. It is significant that the German soldiers near Bolimov were also very afraid of chlorine and even tried to object to its use. But the high command from Berlin was inexorable.

No less significant is the fact that, just like the British and French at Ypres, the Russians were also aware of the impending gas attack. The Germans, with balloon batteries already placed in the forward trenches, waited 10 days for a favorable wind, and during this time the Russians took several “tongues”. Moreover, the command already knew the results of using chlorine near Ypres, but they still did not warn the soldiers and officers in the trenches about anything. True, due to the threat of the use of chemicals, “gas masks” were ordered from Moscow itself - the first, not yet perfect gas masks. But by an evil irony of fate, they were delivered to the divisions attacked by chlorine on the evening of May 31, after the attack.

A month later, on the night of July 7, 1915, the Germans repeated the gas attack in the same area, not far from Bolimov near the village of Volya Shidlovskaya. “This time the attack was no longer as unexpected as on May 31,” wrote a participant in those battles. “However, the chemical discipline of the Russians was still very low, and the passage of the gas wave caused the abandonment of the first line of defense and significant losses.”

Despite the fact that the troops had already begun to be supplied with primitive “gas masks,” they did not yet know how to properly respond to gas attacks. Instead of wearing masks and waiting for the cloud of chlorine to blow through the trenches, the soldiers began to run in panic. It is impossible to outrun the wind by running, and they, in fact, ran in a gas cloud, which increased the time they spent in chlorine vapor, and fast running only aggravated the damage to the respiratory system.

As a result, parts of the Russian army suffered heavy losses. The 218th Infantry suffered 2,608 casualties. In the 21st Siberian Regiment, after retreating in a cloud of chlorine, less than a company remained combat-ready; 97% of the soldiers and officers were poisoned. The troops also did not yet know how to conduct chemical reconnaissance, that is, identify heavily contaminated areas of the area. Therefore, the Russian 220th Infantry Regiment launched a counterattack through terrain contaminated with chlorine, and lost 6 officers and 1,346 privates from gas poisoning.

“Due to the enemy’s complete indiscriminateness in means of combat”

Just two days after the first gas attack against Russian troops, Grand Duke Nikolai Nikolaevich changed his mind about chemical weapons. On June 2, 1915, a telegram was sent from him to Petrograd: “The Supreme Commander-in-Chief admits that, due to the complete indiscriminateness of our enemy in the means of struggle, the only measure of influence on him is the use on our part of all the means used by the enemy. The Commander-in-Chief asks for orders to carry out the necessary tests and supply the armies with appropriate devices with a supply of poisonous gases.”

But the formal decision to create chemical weapons in Russia was made a little earlier - on May 30, 1915, Order No. 4053 of the War Ministry appeared, which stated that “the organization of the procurement of gases and asphyxiants and the conduct of the active use of gases is entrusted to the Commission for the Procurement of Explosives " This commission was headed by two guard colonels, both Andrei Andreevich - artillery chemistry specialists A.A. Solonin and A.A. Dzerzhkovich. The first was assigned to be in charge of “gases, their preparation and use,” the second was “to manage the matter of equipping projectiles” with poisonous chemistry.

So, since the summer of 1915, the Russian Empire became concerned with the creation and production of its own chemical weapons. And in this matter, the dependence of military affairs on the level of development of science and industry was especially clearly demonstrated.

On the one hand, by the end of the 19th century in Russia there was a powerful scientific school in the field of chemistry; it is enough to recall the epoch-making name of Dmitry Mendeleev. But, on the other hand, the Russian chemical industry in terms of production level and volumes was seriously inferior to the leading powers of Western Europe, primarily Germany, which at that time was the leader in the world chemical market. For example, in 1913, all chemical production in the Russian Empire - from the production of acids to the production of matches - employed 75 thousand people, while in Germany over a quarter of a million workers were employed in this industry. In 1913, the value of the products of all chemical production in Russia amounted to 375 million rubles, while Germany that year alone sold 428 million rubles (924 million marks) worth of chemical products abroad.

By 1914, there were less than 600 people in Russia with a higher chemical education. There was not a single special chemical-technological university in the country; only eight institutes and seven universities in the country trained a small number of chemist specialists.

It should be noted here that the chemical industry in wartime is needed not only for the production of chemical weapons - first of all, its capacity is required for the production of gunpowder and other explosives, which are needed in gigantic quantities. Therefore, there were no longer state-owned “state-owned” factories in Russia that had spare capacity for the production of military chemicals.

Under these conditions, the first producer of “asphyxiating gases” was the private manufacturer Gondurin, who proposed to produce phosgene gas at his plant in Ivanovo-Voznesensk, an extremely toxic volatile substance with the smell of hay that affects the lungs. Since the 18th century, Hondurin merchants have been producing chintz, so by the beginning of the 20th century, their factories, thanks to the work on dyeing fabrics, had some experience in chemical production. The Russian Empire entered into a contract with the merchant Hondurin for the supply of phosgene in an amount of at least 10 poods (160 kg) per day.

Meanwhile, on August 6, 1915, the Germans attempted to carry out a large gas attack against the garrison of the Russian fortress of Osovets, which had been successfully holding the defense for several months. At 4 o'clock in the morning they released a huge cloud of chlorine. The gas wave, released along a front 3 kilometers wide, penetrated to a depth of 12 kilometers and spread outward to 8 kilometers. The height of the gas wave rose to 15 meters, the gas clouds this time were green in color - it was chlorine mixed with bromine.

Three Russian companies that found themselves at the epicenter of the attack were completely killed. According to surviving eyewitnesses, the consequences of that gas attack looked like this: “All the greenery in the fortress and in the immediate area along the path of the gases was destroyed, the leaves on the trees turned yellow, curled up and fell off, the grass turned black and lay on the ground, flower petals flew off. All copper objects in the fortress - parts of guns and shells, washbasins, tanks, etc. - were covered with a thick green layer of chlorine oxide.”

However, this time the Germans were unable to build on the success of the gas attack. Their infantry rose to attack too early and suffered losses from the gas. Then two Russian companies counterattacked the enemy through a cloud of gases, losing up to half of the soldiers poisoned - the survivors, with swollen veins on their gas-stricken faces, launched a bayonet attack, which lively journalists in the world press would immediately call the “attack of the dead.”

Therefore, the warring armies began to use gases in increasing quantities - if in April near Ypres the Germans released almost 180 tons of chlorine, then by the fall in one of the gas attacks in Champagne - already 500 tons. And in December 1915, a new, more toxic gas, phosgene, was used for the first time. Its “advantage” over chlorine was that the gas attack was difficult to determine - phosgene is transparent and invisible, has a faint smell of hay, and does not begin to act immediately after inhalation.

Germany's widespread use of poisonous gases on the fronts of the Great War forced the Russian command to also enter the chemical arms race. At the same time, two problems had to be urgently solved: firstly, to find a way to protect against new weapons, and secondly, “not to remain in debt to the Germans,” and to answer them in kind. The Russian army and industry coped with both more than successfully. Thanks to the outstanding Russian chemist Nikolai Zelinsky, already in 1915 the world's first universal effective gas mask was created. And in the spring of 1916, the Russian army carried out its first successful gas attack.
The Empire needs poison

Before responding to German gas attacks with the same weapon, the Russian army had to establish its production almost from scratch. Initially, the production of liquid chlorine was created, which before the war was completely imported from abroad.

This gas began to be supplied by pre-war and converted production facilities - four plants in Samara, several enterprises in Saratov, one plant each near Vyatka and in the Donbass in Slavyansk. In August 1915, the army received the first 2 tons of chlorine; a year later, by the fall of 1916, the production of this gas reached 9 tons per day.

An illustrative story happened with the plant in Slavyansk. It was created at the very beginning of the 20th century to produce bleach electrolytically from rock salt mined in local salt mines. That is why the plant was called “Russian Electron”, although 90% of its shares belonged to French citizens.

In 1915, it was the only plant located relatively close to the front and theoretically capable of quickly producing chlorine on an industrial scale. Having received subsidies from the Russian government, the plant did not provide the front with a ton of chlorine during the summer of 1915, and at the end of August, management of the plant was transferred to the hands of the military authorities.

Diplomats and newspapers, seemingly allied with France, immediately made noise about the violation of the interests of French owners in Russia. The tsarist authorities were afraid of quarreling with their Entente allies, and in January 1916, management of the plant was returned to the previous administration and even new loans were provided. But until the end of the war, the plant in Slavyansk did not begin to produce chlorine in the quantities stipulated by military contracts.
An attempt to obtain phosgene from private industry in Russia also failed - Russian capitalists, despite all their patriotism, inflated prices and, due to the lack of sufficient industrial capacity, could not guarantee timely fulfillment of orders. For these needs, new state-owned production facilities had to be created from scratch.

Already in July 1915, construction began on a “military chemical plant” in the village of Globino in what is now the Poltava region of Ukraine. Initially, they planned to establish chlorine production there, but in the fall it was reoriented to new, more deadly gases - phosgene and chloropicrin. For the combat chemicals plant, the ready-made infrastructure of a local sugar factory, one of the largest in the Russian Empire, was used. Technical backwardness led to the fact that the enterprise took more than a year to build, and the Globinsky Military Chemical Plant began producing phosgene and chloropicrin only on the eve of the February revolution of 1917.

The situation was similar with the construction of the second large state enterprise for the production of chemical weapons, which began to be built in March 1916 in Kazan. The Kazan Military Chemical Plant produced the first phosgene in 1917.

Initially, the War Ministry hoped to organize large chemical plants in Finland, where there was an industrial base for such production. But bureaucratic correspondence on this issue with the Finnish Senate dragged on for many months, and by 1917 the “military chemical plants” in Varkaus and Kajaan were still not ready.
While state-owned factories were just being built, the War Ministry had to buy gases wherever possible. For example, on November 21, 1915, 60 thousand pounds of liquid chlorine were ordered from the Saratov city government.

"Chemical Committee"

Since October 1915, the first “special chemical teams” began to be formed in the Russian army to carry out gas balloon attacks. But due to the initial weakness of Russian industry, it was not possible to attack the Germans with new “poisonous” weapons in 1915.

To better coordinate all efforts to develop and produce combat gases, in the spring of 1916, the Chemical Committee was created under the Main Artillery Directorate of the General Staff, often simply called the “Chemical Committee”. All existing and newly created chemical weapons factories and all other work in this area were subordinated to him.

The Chairman of the Chemical Committee was 48-year-old Major General Vladimir Nikolaevich Ipatiev. A major scientist, he had not only military, but also professorial rank, and before the war he taught a course in chemistry at St. Petersburg University.

Gas mask with ducal monograms


The first gas attacks immediately required not only the creation of chemical weapons, but also means of protection against them. In April 1915, in preparation for the first use of chlorine at Ypres, the German command provided its soldiers with cotton pads soaked in a sodium hyposulfite solution. They had to cover the nose and mouth during the release of gases.

By the summer of that year, all soldiers of the German, French and English armies were equipped with cotton-gauze bandages soaked in various chlorine neutralizers. However, such primitive “gas masks” turned out to be inconvenient and unreliable; moreover, while mitigating the damage from chlorine, they did not provide protection against the more toxic phosgene.

In Russia, in the summer of 1915, such bandages were called “stigma masks.” They were made for the front by various organizations and individuals. But as the German gas attacks showed, they hardly saved anyone from the massive and prolonged use of toxic substances, and were extremely inconvenient to use - they quickly dried out, completely losing their protective properties.

In August 1915, Moscow University professor Nikolai Dmitrievich Zelinsky proposed using activated charcoal as a means of absorbing toxic gases. Already in November, Zelinsky’s first carbon gas mask was tested for the first time complete with a rubber helmet with glass “eyes”, which was made by an engineer from St. Petersburg, Mikhail Kummant.



Unlike previous designs, this one turned out to be reliable, easy to use and ready for immediate use for many months. The resulting protective device successfully passed all tests and was called the “Zelinsky-Kummant gas mask.” However, here the obstacles to the successful arming of the Russian army with them were not even the shortcomings of Russian industry, but the departmental interests and ambitions of officials. At that time, all work on protection against chemical weapons was entrusted to the Russian general and the German Prince Friedrich (Alexander Petrovich) of Oldenburg, a relative of the ruling Romanov dynasty, who held the position of Supreme Chief of the sanitary and evacuation unit of the imperial army. The prince by that time was almost 70 years old and Russian society remembered him as the founder of the resort in Gagra and a fighter against homosexuality in the guard. The prince actively lobbied for the adoption and production of a gas mask, which was designed by teachers of the Petrograd Mining Institute using experience in the mines. This gas mask, called the “gas mask of the Mining Institute,” as tests showed, provided worse protection from asphyxiating gases and was more difficult to breathe in than the Zelinsky-Kummant gas mask.

Despite this, the Prince of Oldenburg ordered the production of 6 million “Mining Institute gas masks”, decorated with his personal monogram, to begin. As a result, Russian industry spent several months producing a less advanced design. On March 19, 1916, at a meeting of the Special Conference on Defense - the main body of the Russian Empire for managing the military industry - an alarming report was made about the situation at the front with “masks” (as gas masks were then called): “Masks of the simplest type weakly protect against chlorine, but not at all protect against other gases. Mining Institute masks are not suitable. The production of Zelinsky’s masks, long recognized as the best, has not been established, which should be considered criminal negligence.”

As a result, only the unanimous opinion of the military allowed the mass production of Zelinsky’s gas masks to begin. On March 25, the first government order appeared for 3 million and the next day for another 800 thousand gas masks of this type. By April 5, the first batch of 17 thousand had already been produced. However, until the summer of 1916, the production of gas masks remained extremely insufficient - in June no more than 10 thousand pieces per day arrived at the front, while millions of them were required to reliably protect the army. Only the efforts of the “Chemical Commission” of the General Staff made it possible to radically improve the situation by the fall - by the beginning of October 1916, over 4 million different gas masks were sent to the front, including 2.7 million “Zelinsky-Kummant gas masks.” In addition to gas masks for people, during the First World War it was necessary to attend to special gas masks for horses, which then remained the main draft force of the army, not to mention the numerous cavalry. By the end of 1916, 410 thousand horse gas masks of various designs arrived at the front.


In total, during the First World War, the Russian army received over 28 million gas masks of various types, of which over 11 million were the Zelinsky-Kummant system. Since the spring of 1917, only they were used in combat units of the active army, thanks to which the Germans abandoned “gas balloon” attacks with chlorine on the Russian front due to their complete ineffectiveness against troops wearing such gas masks.

“The war has crossed the last line»

According to historians, about 1.3 million people suffered from chemical weapons during the First World War. The most famous of them, perhaps, was Adolf Hitler - on October 15, 1918, he was poisoned and temporarily lost his sight as a result of a nearby explosion of a chemical shell. It is known that in 1918, from January until the end of the fighting in November, the British lost 115,764 soldiers from chemical weapons. Of these, less than one tenth of one percent died - 993. Such a small percentage of fatal losses from gases is associated with the full equipment of the troops with advanced types of gas masks. However, a large number of wounded, or rather poisoned and lost combat capability, left chemical weapons a formidable force on the fields of the First World War.

The US Army entered the war only in 1918, when the Germans brought the use of a variety of chemical shells to maximum and perfection. Therefore, of all the losses of the American army, more than a quarter were due to chemical weapons. These weapons not only killed and wounded, but when used massively and for a long time, they rendered entire divisions temporarily incapable of combat. Thus, during the last offensive of the German army in March 1918, during artillery preparation against the 3rd British Army alone, 250 thousand shells with mustard gas were fired. British soldiers on the front line had to continuously wear gas masks for a week, which made them almost unfit for combat. The losses of the Russian army from chemical weapons in the First World War are estimated with a wide range. During the war, these figures were not made public for obvious reasons, and two revolutions and the collapse of the front by the end of 1917 led to significant gaps in the statistics.

The first official figures were published already in Soviet Russia in 1920 - 58,890 non-fatally poisoned and 6,268 died from gases. Research in the West, which came out hot on the heels of the 20-30s of the 20th century, cited much higher numbers - over 56 thousand killed and about 420 thousand poisoned. Although the use of chemical weapons did not lead to strategic consequences, its impact on the psyche of soldiers was significant. Sociologist and philosopher Fyodor Stepun (by the way, himself of German origin, real name Friedrich Steppuhn) served as a junior officer in the Russian artillery. Even during the war, in 1917, his book “From the Letters of an Ensign Artillery Officer” was published, where he described the horror of people who survived a gas attack: “Night, darkness, a howl overhead, the splash of shells and the whistling of heavy fragments. It's so difficult to breathe that you feel like you're about to suffocate. The voices in the masks are almost inaudible, and in order for the battery to accept the command, the officer needs to shout it directly into the ear of each gunner. At the same time, the terrible unrecognizability of the people around you, the loneliness of the damned tragic masquerade: white rubber skulls, square glass eyes, long green trunks. And all in the fantastic red sparkle of explosions and shots. And above everything there was an insane fear of heavy, disgusting death: the Germans shot for five hours, but the masks were designed for six.

You can't hide, you have to work. With every step, it stings your lungs, knocks you over backwards, and the feeling of suffocation intensifies. And you need to not only walk, you need to run. Perhaps the horror of the gases is not characterized more clearly by anything than by the fact that in the gas cloud no one paid any attention to the shelling, but the shelling was terrible - more than a thousand shells fell on one of our batteries...
In the morning, after the shelling stopped, the appearance of the battery was terrible. In the dawn fog, people are like shadows: pale, with bloodshot eyes, and with the coal of gas masks settling on their eyelids and around their mouths; many are sick, many are fainting, the horses are all lying on the hitching post with dull eyes, with bloody foam at the mouth and nostrils, some are in convulsions, some have already died.”
Fyodor Stepun summed up these experiences and impressions of chemical weapons as follows: “After the gas attack in the battery, everyone felt that the war had crossed the last line, that from now on everything was allowed to it and nothing was sacred.”
The total losses from chemical weapons in WWI are estimated at 1.3 million people, of which up to 100 thousand were fatal:

British Empire - 188,706 people were affected, of whom 8,109 died (according to other sources, on the Western Front - 5,981 or 5,899 out of 185,706 or 6,062 out of 180,983 British soldiers);
France - 190,000, 9,000 died;
Russia - 475,340, 56,000 died (according to other sources, out of 65,000 victims, 6,340 died);
USA - 72,807, 1,462 died;
Italy - 60,000, 4,627 died;
Germany - 200,000, 9,000 died;
Austria–Hungary - 100,000, 3,000 died.

  1. I'll start the topic.

    Livens Projector

    (Great Britain)

    Livens Projector - Livens' gas launcher. Developed by military engineer Captain William H. Livens in early 1917. First used on April 4, 1917 during the attack on Arras. To work with the new weapons, “Special Companies” No. 186, 187, 188, 189 were created. Intercepted German reports reported that the density of poisonous gases was similar to a cloud released from gas cylinders. The emergence of a new gas delivery system came as a surprise to the Germans. Soon, German engineers developed an analogue of the Livens Projector.

    The Livens Projector was more efficient than earlier methods of delivering gases. When the gas cloud reached enemy positions, its concentration decreased.

    The Livens Projector consisted of a steel pipe with a diameter of 8 inches (20.3 cm). Wall thickness 1.25 inches (3.17 cm). Available in two sizes: 2 feet 9 inches (89 cm) and 4 feet (122 cm). The pipes were buried in the ground at an angle of 45 degrees for stability. The projectile was fired according to an electrical signal.

    The shells contained 30-40 pounds (13-18 kg) of toxic substances. Firing range 1200 - 1900 meters depending on the length of the barrel.

    During the war, the British Army fired approximately 300 gas salvos using the Livens Projector. The largest use occurred on March 31, 1918 near Lens. Then 3728 Livens Projector participated.

    The German analogue had a diameter of 18 cm. The projectile contained 10-15 liters of toxic substances. It was first used in December 1917.

    In August 1918, German engineers presented a mortar with a diameter of 16 cm and a firing range of 3500 meters. The shell contained 13 kg. toxic substances (usually phosgene) and 2.5 kg. pumice.

  2. Haber and Einstein, Berlin, 1914

    Fritz Haber

    (Germany)

    Fritz Haber (German Fritz haber, December 9, 1868, Breslau - January 29, 1934, Basel) - chemist, Nobel Prize laureate in chemistry (1918).

    By the beginning of the war, Haber was in charge (from 1911) of a laboratory at the Kaiser Wilhelm Institute for Physical Chemistry in Berlin. Haber's work was financed by the Prussian nationalist Karl Duisberg, who was also the head of the chemical concern Interessen Germinschaft (IG Cartel). Haber had virtually unlimited funding and technical support. After the war began, he began developing chemical weapons. Duisberg was formally against the use of chemical weapons, and at the beginning of the war he met with the German High Command. Duisbaer also began to independently investigate the potential use of chemical weapons. Haber agreed with Duisberg's point of view.

    In the fall of 1914, the Wilhelm Institute began developing poison gases for military use. Haber and his laboratory began developing chemical weapons, and by January 1915, Haber's laboratory had a chemical agent that could be presented to High Command. Haber was also developing a protective mask with a filter.

    Haber chose chlorine, which had been produced in large quantities in Germany before the war. In 1914, Germany produced 40 tons of chlorine daily. Haber proposed storing and transporting chlorine in liquid form, under pressure, in steel cylinders. The cylinders had to be delivered to the fighting positions, and if there was a favorable wind, the chlorine was released towards the enemy positions.

    The German command was in a hurry to use new weapons on the western front, but the generals had difficulty imagining the possible consequences. Duisberg and Haber were well aware of the effect the new weapon would have, and Haber decided to be present at the first use of chlorine. The site of the first attack was the town of Langemarck near Ypres. At 6 km. The site housed French reservists from Algeria and the Canadian division. The date of the attack was April 22, 1915.

    160 tons of liquid chlorine in 6,000 cylinders were secretly placed along the German lines. A yellow-green cloud covered the French positions. Gas masks did not yet exist. The gas penetrated into all the cracks of the shelters. Those who tried to escape were accelerated by the effects of the chlorine, and died faster. The attack killed 5,000 people. Another 15,000 people were poisoned. The Germans, wearing gas masks, occupied the French positions, advancing 800 yards.

    A few days before the first gas attack, a German soldier with a gas mask was captured. He spoke about the impending attack, and about the gas cylinders. His testimony was confirmed by aerial reconnaissance. But the report on the impending attack was lost in the bureaucratic structures of the Allied command. Later, French and British generals denied the existence of this report.

    It became clear to the German command and Haber that the Allies would soon also develop and begin to use chemical weapons.

    Nikolai Dmitrievich Zelinsky was born on January 25 (February 6), 1861 in Tiraspol, Kherson province.

    In 1884 he graduated from Novorossiysk University in Odessa. In 1889 he defended his master's thesis, and in 1891 his doctoral dissertation. 1893-1953 professor at Moscow University. In 1911 he left the university together with a group of scientists in protest against the policy of the Tsarist Minister of Public Education L. A. Kasso. From 1911 to 1917 he worked as director of the Central Laboratory of the Ministry of Finance and head of the department at the Polytechnic Institute of St. Petersburg.

    Died on July 31, 1953. Buried at Novodevichy Cemetery in Moscow. The Institute of Organic Chemistry in Moscow is named after Zelinsky.

    Developed by Professor Zelinsky Nikolai Dmitrievich.

    Before this, inventors of protective equipment offered masks that protected only from one type of toxic substance. For example, the mask against chlorine of the British doctor Cluny MacPherson (Cluny MacPherson 1879-1966). Zelinsky created a universal absorber from charcoal. Zelinsky developed a method for activating coal - increasing its ability to absorb various substances on its surface. Activated carbon was obtained from birch wood.

    Simultaneously with Zelinsky’s gas mask, a prototype of the head of the sanitary and evacuation unit of the Russian army, Prince A.P., was tested. Oldenburgsky. The gas mask of the Prince of Oldenburg contained an absorbent made of non-activated carbon with soda lime. When breathing, the absorbent turned to stone. The device failed even after several training sessions.

    Zelinsky completed work on the absorber in June 1915. In the summer of 1915, Zelinsky tested the absorber on himself. Two gases, chlorine and phosgene, were introduced into one of the isolated rooms of the central laboratory of the Ministry of Finance in Petrograd. Zelinsky, wrapping about 50 grams of activated birch charcoal crushed into small pieces in a handkerchief, pressing the handkerchief tightly to his mouth and nose and closing his eyes, was able to stay in this poisoned atmosphere, inhaling and exhaling through the handkerchief, for several minutes.

    In November 1915, engineer E. Kummant developed a rubber helmet with goggles, which made it possible to protect the respiratory system and most of the head.

    On February 3, 1916, at the Headquarters of the Supreme Commander-in-Chief near Mogilev, on the personal order of Emperor Nicholas II, demonstration tests were carried out on all available samples of anti-chemical protection, both Russian and foreign. For this purpose, a special laboratory car was attached to the royal train. Zelinsky-Kummant's gas mask was tested by Zelinsky's laboratory assistant, Sergei Stepanovich Stepanov. S.S. Stepanov was able to stay in a closed carriage filled with chlorine and phosgene for more than an hour. Nicholas II ordered that S.S. Stepanov be awarded the St. George Cross for his courage.

    The gas mask entered service with the Russian army in February 1916. The Zelinsky-Kummant gas mask was also used by the Entente countries. In 1916-1917 Russia produced more than 11 million units. Zelinsky-Kummant gas masks.

    The gas mask had some drawbacks. For example, before use it had to be purged of coal dust. A box of coal attached to the mask limited head movement. But Zelinsky's activated carbon absorber has become the most popular in the world.

  3. (Great Britain)

    Hypo Helmet entered service in 1915. The Hypo Helmet was a simple flannel bag with a single mica window. The bag was impregnated with an absorber. The Hypo Helmet provided good protection against chlorine, but did not have an exhalation valve, making it difficult to breathe in.

    *********************************************************

    (Great Britain)

    P helmet, PH helmet and PHG helmet are early masks designed to protect against chlorine, phosgene and tear gases.

    P Helmet (also known as Tube Helmet) entered service in July 1915 to replace the Hypo Helmet. The Hypo Helmet was a simple flannel bag with a single mica window. The bag was impregnated with an absorber. The Hypo Helmet provided good protection against chlorine, but did not have an exhalation valve, making it difficult to breathe in.

    P Helmet had round glasses made of mica, and also introduced an exhalation valve. Inside the mask, a short tube from the breathing valve was inserted into the mouth. P Helmet consisted of two layers of flannel - one layer was impregnated with absorbent, the other was not impregnated. The fabric was impregnated with phenol and glycerin. Phenol with glycerin protected against chlorine and phosgene, but not against tear gases.

    About 9 million copies were produced.

    PH Helmet (Phenate Hexamine) entered service in October 1915. The fabric was impregnated with hexamethylenetetramine, which improved protection against phosgene. Protection against hydrocyanic acid has also appeared. About 14 million copies were produced. The PH Helmet remained in service until the end of the war.

    The PHG Helmet entered service in January 1916. It differed from the PH Helmet in its rubber front part. There is protection against tear gases. In 1916 -1917 About 1.5 million copies were produced.

    In February 1916, fabric masks were replaced by the Small Box Respirator.

    In the photo - PH Helmet.

    Small Box Respirator

    (Great Britain)

    Small Box Respirator type 1. Adopted by the British Army in 1916.

    The Small Box Respirator replaced the simplest P Helmet masks that had been in use since 1915. The metal box contained activated carbon with layers of alkaline permanganate. The box was connected to the mask with a rubber hose. The hose was connected to a metal tube in the mask. The other end of the metal tube was inserted into the mouth. Inhalation and exhalation was done only through the mouth - through a tube. The nose was pinched inside the mask. The breathing valve was located at the bottom of the metal tube (visible in the photograph).

    Small Box Respirator of the first type was also produced in the USA. The US Army used gas masks copied from the Small Box Respirator for several years.

    Small Box Respirator type 2. Adopted by the British Army in 1917.

    An improved version of Type 1. The metal box contained activated carbon with layers of alkali permanganate. The box was connected to the mask with a rubber hose. The hose was connected to a metal tube in the mask. The other end of the metal tube was inserted into the mouth. Inhalation and exhalation was done only through the mouth - through a tube. The nose was pinched inside the mask.

    Unlike type 1, a metal loop appeared on the breathing valve (at the bottom of the tube) (visible in the photo). Its purpose is to protect the breathing valve from damage. There are also additional attachments for the mask to the belts. There are no other differences from type 1.

    The mask was made of rubberized fabric.

    The Small Box Respirator was replaced in the 1920s by the Mk III gas mask.

  4. (France)

    The first French mask, Tampon T, began to be developed at the end of 1914. Intended for protection against phosgene. Like all the first masks, it consisted of several layers of fabric soaked in chemicals.

    A total of 8 million copies of Tampon T were produced. It was produced in Tampon T and Tampon TN variants. Usually used with glasses, as in the photo. Kept in a cloth bag.

    In April 1916, it began to be replaced by M2.

    ********************************************************

    (France)

    M2 (2nd model) - French gas mask. Entered service in April 1916 to replace Tampon T and Tampon TN.

    M2 consisted of several layers of fabric impregnated with chemicals. M2 was placed in a semicircular bag or tin box.

    The M2 was used by the US Army.

    In 1917, the French Army began replacing the M2 with the A.R.S. (Appareil Respiratoire Special). Over two years, 6 million M2 units were produced. A.R.S. became widespread only in May 1918.

    **********************************************************

    Gummischutzmaske

    (Germany)

    Gummischutzmaske (rubber mask) - the first German mask. Entered service at the end of 1915. It consisted of a rubberized mask made of cotton fabric and a round filter. The mask did not have an exhalation valve. To prevent the glasses from fogging up, the mask had a special fabric pocket into which one could insert a finger and wipe the glasses from inside the mask. The mask was held on the head with fabric straps. Celluloid glasses.

    The filter was filled with granulated charcoal impregnated with reagents. It was assumed that the filter would be replaceable - for different gases. The mask was stored in a round metal box.

    German gas mask, 1917

  5. A new means of chemical attack - gas launchers - appeared on the fields of the Great War in 1917. The primacy in their development and application belongs to the British. The first gas launcher was designed by Captain William Howard Livens of the Corps of Royal Engineers. While serving in the Special Chemical Company, Livens, working on a flamethrower, created a simple and reliable propellant in 1916, which was designed to fire ammunition filled with oil. For the first time, such flamethrowers were used in large quantities on July 1, 1916 at the Battle of the Somme (one of the places of use was Ovillers-la-Boisselle). The fire range was initially no more than 180 meters, but later it was increased to 1200 meters. In 1916, the oil in the shells was replaced with chemical agents and gas launchers - this is how the new weapon was now called; it was tested in September of the same year during the battle on the river. Somme in the area of ​​Thiepval and Hamel and in November near Beaumont-Hamel. According to the German side, the first gas launcher attack was carried out later - on April 4, 1917 near Arras.

    General structure and diagram of the Livens Gazomet

    The Livens Projector consisted of a steel pipe (barrel), tightly closed at the breech, and a steel plate (pan) used as a base. The gas launcher was almost completely buried in the ground at an angle of 45 degrees to the horizontal. The gas launchers were charged with ordinary gas cylinders that had a small explosive charge and a head fuse. The weight of the cylinder was about 60 kg. The cylinder contained from 9 to 28 kg of toxic substances, mainly asphyxiating - phosgene, liquid diphosgene and chloropicrin. When the explosive charge, which passed through the middle of the entire cylinder, exploded, the chemical agent was sprayed out. The use of gas cylinders as ammunition was due to the fact that as gas cylinder attacks were abandoned, a large number of cylinders that became unnecessary, but still usable, accumulated. Subsequently, specially designed ammunition replaced the cylinders.
    The shot was fired using an electric fuse, which ignited the propellant charge. Gas launchers were connected by electric wires into batteries of 100 pieces, and the entire battery was fired simultaneously. The fire range of the gas launcher was 2500 meters. The duration of the salvo was 25 seconds. Usually one salvo was fired per day, since the gas launcher positions became easy targets for the enemy. Unmasking factors were large flashes at gas-throwing positions and the specific noise of flying mines, reminiscent of rustling. The most effective was considered to be the use of 1,000 to 2,000 gas-throwing cannons, due to which, in a short time, a high concentration of chemical warfare agents was created in the area where the enemy was located, due to which most filtering gas masks became useless During the war, 140,000 Livens gas launchers and 400,000 bombs for them were manufactured. On January 14, 1916, William Howard Leavens was awarded the Military Cross.
    Livens gas launchers in position

    The use of gas launchers by the British forced other participants in the war to quickly adopt this new method of chemical attack. By the end of 1917, the armies of the Entente (with the exception of Russia, which found itself on the threshold of the Civil War) and the Triple Alliance were armed with gas launchers

    The German army received 180-mm smooth-walled and 160-mm rifled gas launchers with a firing range of up to 1.6 and 3 km, respectively. The Germans carried out their first gas launcher attacks in the Western theater of operations in December 1917 at Remicourt, Cambrai and Givenchy.

    German gas launchers caused the “Miracle at Caporetto” during the 12th battle on the river. Isonzo October 24-27, 1917 on the Italian Front. The massive use of gas launchers by the Kraus group advancing in the Isonzo River valley led to a rapid breakthrough of the Italian front. This is how the Soviet military historian Alexander Nikolaevich De-Lazari describes this operation.

    Loading Livens gas launchers by English soldiers

    “The battle began with the offensive of the Austro-German armies, in which the main blow was delivered by the right flank with a force of 12 divisions (the Austrian Kraus group - three Austrian and one German infantry divisions and the 14th German army of General Belov - eight German infantry divisions on the Flitch - Tolmino front ( about 30 km) with the task of reaching the Gemona - Cividale front.

    In this direction, the defensive line was occupied by units of the 2nd Italian Army, on the left flank of which an Italian infantry division was located in the Flitsch area. It blocked the exit from the gorge to the river valley. The isonzo itself Flitch was occupied by a battalion of infantry defending three lines of positions crossing the valley. This battalion, making extensive use of so-called “cave” batteries and firing points for the purpose of defense and flanking approaches, i.e., located in caves cut into steep rocks, turned out to be inaccessible to the artillery fire of the advancing Austro-German troops and successfully delayed their advance. A salvo of 894 chemical mines was fired, followed by 2 salvos of 269 high explosive mines. The entire Italian battalion of 600 people with horses and dogs was found dead as the Germans advanced (some of the people were wearing gas masks). Kraus's group then took all three rows of Italian positions in a sweeping manner and reached the mountain valleys of Bergon by evening. To the south, the attacking units met more stubborn Italian resistance. It was broken the next day - October 25, which was facilitated by the successful advance of the Austro-Germans at Flitch. On October 27, the front was shaken all the way to the Adriatic Sea, and on that day the advanced German units occupied Cividale. The Italians, gripped by panic, retreated everywhere. Almost all the enemy artillery and a mass of prisoners fell into the hands of the Austro-Germans. The operation was a brilliant success. This is how the famous “Miracle at Caporetto”, known in military literature, took place, in which the initial episode - the successful use of gas launchers - received operational significance).

    Livens gas launchers: A – a battery of buried Livens gas launchers with a projectile and propellant charge lying on the ground near the battery; B – longitudinal section of a Livens gas launcher projectile. Its central part contains a small explosive charge, which disperses the chemical agent by detonating

    Kraus's group consisted of selected Austro-Hungarian divisions trained for war in the mountains. Since they had to operate in high mountainous terrain, the command allocated relatively less artillery to support the divisions than other groups. But they had 1,000 gas launchers, which the Italians were not familiar with. The effect of surprise was greatly aggravated by the use of toxic substances, which until then had been very rarely used on the Austrian front. To be fair, it should be noted that the cause of the “Miracle at Caporetto” was not only gas launchers. The 2nd Italian Army under the command of General Luigi Capello, which was stationed in the Caporetto area, was not distinguished by its high combat capability. As a result of a miscalculation by the army command, Capello ignored the warning of the Chief of the General Staff about a possible German attack; in the direction of the enemy’s main attack, the Italians had fewer forces and remained unprepared for the attack. In addition to the gas launchers, what was unexpected was the German offensive tactics, based on the penetration of small groups of soldiers deep into the defense, which caused panic among the Italian troops. Between December 1917 and May 1918, German troops launched 16 attacks on the British using gas cannons. However, their result, due to the development of chemical protection means, was no longer so significant. The combination of the action of gas launchers with artillery fire increased the effectiveness of the use of BOV and made it possible to almost completely abandon gas-balloon attacks by the end of 1917. The dependence of the latter on weather conditions and the lack of tactical flexibility and controllability led to the fact that a gas attack as a means of combat never left the tactical field and did not become a factor in an operational breakthrough. Although there was such a possibility, caused by surprise and the lack of protective equipment, at first. “The massive use, based on theoretical and practical experiments, gave a new type of chemical warfare - shooting with chemical projectiles and gas throwing - operational significance" (A.N. De-Lazari) . However, it should be noted that gas throwing (i.e. firing from gas launchers) was also not destined to become a factor of operational significance comparable to artillery

    By the way, Hitler, being a corporal in the First World War in 1918, was gassed near La Montaigne as a result of the explosion of a chemical shell near him. The result is eye damage and temporary loss of vision. Well, that's by the way

    Please! By the way, in my battlefields in WWII, chemical weapons were also actively used: both poisonous gases and chemical weapons. ammunition.
    RIA hit the Germans with phosgene shells, and they, in turn, responded in kind...but let’s continue the topic!

    The First World War showed the world many new means of destruction: aviation was widely used for the first time, the first steel monsters - tanks - appeared on the fronts of the Great War, but poisonous gases became the most terrible weapon. The horror of a gas attack hovered over the battlefields torn apart by shells. Nowhere and never, neither before nor after, have chemical weapons been used so massively. What was it like?

    Types of chemical agents used during the First World War. (brief information)

    Chlorine as a poisonous gas.
    Scheele, who received chlorine, noted a very unpleasant strong odor, difficulty breathing and coughing. As we later found out, a person smells chlorine even if one liter of air contains only 0.005 mg of this gas, and at the same time it already has an irritating effect on the respiratory tract, destroying the cells of the mucous membrane of the respiratory tract and lungs. A concentration of 0.012 mg/l is difficult to tolerate; if the concentration of chlorine exceeds 0.1 mg/l, it becomes life-threatening: breathing quickens, becomes convulsive, and then becomes increasingly rare, and after 5–25 minutes breathing stops. The maximum permissible concentration in the air of industrial enterprises is 0.001 mg/l, and in the air of residential areas - 0.00003 mg/l.

    St. Petersburg academician Toviy Egorovich Lovitz, repeating Scheele's experiment in 1790, accidentally released a significant amount of chlorine into the air. After inhaling it, he lost consciousness and fell, then suffered excruciating chest pain for eight days. Fortunately, he recovered. The famous English chemist Davy almost died from chlorine poisoning. Experiments with even small amounts of chlorine are dangerous, as they can cause severe lung damage. They say that the German chemist Egon Wiberg began one of his lectures on chlorine with the words: “Chlorine is a poisonous gas. If I get poisoned during the next demonstration, please take me out into the fresh air. But, unfortunately, the lecture will have to be interrupted.” If you release a lot of chlorine into the air, it becomes a real disaster. This was experienced by the Anglo-French troops during the First World War. On the morning of April 22, 1915, the German command decided to carry out the first gas attack in the history of wars: when the wind blew towards the enemy, on a small six-kilometer section of the front near the Belgian town of Ypres, the valves of 5,730 cylinders were simultaneously opened, each containing 30 kg of liquid chlorine. Within 5 minutes, a huge yellow-green cloud formed, which slowly moved away from the German trenches towards the Allies. The English and French soldiers were completely defenseless. The gas penetrated through the cracks into all the shelters; there was no escape from it: after all, the gas mask had not yet been invented. As a result, 15 thousand people were poisoned, 5 thousand of them to death. A month later, on May 31, the Germans repeated the gas attack on the eastern front - against Russian troops. This happened in Poland near the city of Bolimova. At the 12 km front, 264 tons of a mixture of chlorine and much more toxic phosgene (carbonic acid chloride COCl2) were released from 12 thousand cylinders. The tsarist command knew about what happened at Ypres, and yet the Russian soldiers had no means of defense! As a result of the gas attack, the losses amounted to 9,146 people, of which only 108 were as a result of rifle and artillery shelling, the rest were poisoned. At the same time, 1,183 people died almost immediately.

    Soon, chemists showed how to escape from chlorine: you need to breathe through a gauze bandage soaked in a solution of sodium thiosulfate (this substance is used in photography, it is often called hyposulfite).

    ************************************

    Under normal conditions, phosgene is a colorless gas, 3.5 times heavier than air, with a characteristic odor of rotten hay or rotten fruit. It dissolves poorly in water and is easily decomposed by it. Combat state - steam. Resistance on the ground is 30-50 minutes, stagnation of vapors in trenches and ravines is possible from 2 to 3 hours. The depth of distribution of contaminated air is from 2 to 3 km. First aid. Put a gas mask on the affected person, remove him from the contaminated atmosphere, provide complete rest, make breathing easier (remove the waist belt, unfasten the buttons), cover him from the cold, give him a hot drink and deliver him to a medical center as quickly as possible. Protection against phosgene - a gas mask, a shelter equipped with filter and ventilation units.

    Under normal conditions, phosgene is a colorless gas, 3.5 times heavier than air, with a characteristic odor of rotten hay or rotten fruit. It dissolves poorly in water and is easily decomposed by it. Combat state - steam. Durability on the ground is 30-50 minutes, stagnation of vapors in trenches and ravines is possible from 2 to 3 hours. The depth of distribution of contaminated air is from 2 to 3 km. Phosgene affects the body only when its vapor is inhaled, and mild irritation of the mucous membrane of the eyes, lacrimation, an unpleasant sweetish taste in the mouth, slight dizziness, general weakness, cough, tightness in the chest, nausea (vomiting) are felt. After leaving the contaminated atmosphere, these phenomena disappear, and within 4-5 hours the affected person is in a stage of imaginary well-being. Then, as a result of pulmonary edema, a sharp deterioration in the condition occurs: breathing becomes more frequent, a severe cough with copious production of foamy sputum, headache, shortness of breath, blue lips, eyelids, nose, increased heart rate, pain in the heart, weakness and suffocation appear. Body temperature rises to 38-39°C. Pulmonary edema lasts several days and is usually fatal. The lethal concentration of phosgene in the air is 0.1 - 0.3 mg/l. with exposure 15 min. Phosgene is prepared by the following reaction:

    СO + Cl2 = (140С,С) => COCl2

    *****************

    Diphosgene

    Colorless liquid. Boiling point 128°C. Unlike phosgene, it also has an irritating effect, but is otherwise similar to it. This BHTV is characterized by a latent period of 6-8 hours and a cumulative effect. Affects the body through the respiratory system. Signs of damage are a sweetish, unpleasant taste in the mouth, cough, dizziness, and general weakness. Lethal concentration in the air is 0.5 - 0.7 mg/l. with exposure 15 min.

    *****************

    It has a multilateral damaging effect. In the droplet-liquid and vapor state it affects the skin and eyes, when inhaling vapors it affects the respiratory tract and lungs, and when it comes into contact with food and water, it affects the digestive organs. A characteristic feature of mustard gas is the presence of a period of latent action (the lesion is not detected immediately, but after some time - 4 hours or more). Signs of damage are redness of the skin, the formation of small blisters, which then merge into large ones and after two to three days burst, turning into difficult-to-heal ulcers. With any local damage, it causes general poisoning of the body, which manifests itself in fever, malaise, and complete loss of capacity.

    Mustard gas is a slightly yellowish (distilled) or dark brown liquid with the odor of garlic or mustard, highly soluble in organic solvents and poorly soluble in water. Mustard gas is heavier than water, freezes at a temperature of about 14°C, and is easily absorbed into various paints, rubber and porous materials, which leads to deep contamination. In air, mustard gas evaporates slowly. The main combat state of mustard gas is droplet-liquid or aerosol. However, mustard gas is capable of creating dangerous concentrations of its vapors due to natural evaporation from the contaminated area. In combat conditions, mustard gas could be used by artillery (gas launchers). The defeat of personnel is achieved by contaminating the ground layer of air with vapors and aerosols of mustard gas, contaminating open areas of skin, uniforms, equipment, weapons and military equipment and terrain with aerosols and drops of mustard gas. The depth of distribution of mustard gas vapor ranges from 1 to 20 km for open areas. Mustard gas can infect an area for up to 2 days in summer, and up to 2-3 weeks in winter. Equipment contaminated with mustard gas poses a danger to personnel unprotected by protective equipment and must be decontaminated. Mustard gas infects stagnant bodies of water for 2-3 months.

    Mustard gas has a damaging effect through any route of entry into the body. Damage to the mucous membranes of the eyes, nasopharynx and upper respiratory tract occurs even at low concentrations of mustard gas. At higher concentrations, along with local lesions, general poisoning of the body occurs. Mustard gas has a latent period of action (2-8 hours) and is cumulative. At the time of contact with mustard gas, there is no skin irritation or pain effects. Areas affected by mustard gas are prone to infection. Skin damage begins with redness, which appears 2-6 hours after exposure to mustard gas. After a day, small blisters filled with a yellow transparent liquid form at the site of redness. Subsequently, the bubbles merge. After 2-3 days, the blisters burst and a non-healing lesion forms for 20-30 days. ulcer. If the ulcer gets infected, healing occurs in 2-3 months. When inhaling mustard gas vapors or aerosols, the first signs of damage appear after a few hours in the form of dryness and burning in the nasopharynx, then severe swelling of the nasopharyngeal mucosa occurs, accompanied by purulent discharge. In severe cases, pneumonia develops, death occurs on the 3-4th day from suffocation. The eyes are especially sensitive to mustard vapors. When exposed to mustard gas vapors on the eyes, a feeling of sand appears in the eyes, lacrimation, photophobia, then redness and swelling of the mucous membrane of the eyes and eyelids occurs, accompanied by copious discharge of pus. Contact with droplets of mustard gas in the eyes can lead to blindness. When mustard gas enters the gastrointestinal tract, within 30-60 minutes sharp pain in the stomach, drooling, nausea, vomiting appears, and diarrhea (sometimes with blood) subsequently develops. The minimum dose that causes the formation of abscesses on the skin is 0.1 mg/cm2. Mild eye damage occurs at a concentration of 0.001 mg/l and exposure for 30 minutes. The lethal dose when exposed through the skin is 70 mg/kg (latent period of action up to 12 hours or more). The lethal concentration when exposed through the respiratory system for 1.5 hours is about 0.015 mg/l (latent period 4 - 24 hours). I. was first used by Germany as a chemical agent in 1917 near the Belgian city of Ypres (hence the name). Protection against mustard gas - gas mask and skin protection.

    *********************

    First received in 1904. Even before the end of World War II, it was withdrawn from service with the US Army due to insufficiently high combat effectiveness compared to mustard gas. However, it is often used as an additive to mustard gas to lower the latter's freezing point.

    Physicochemical characteristics:

    A colorless oily liquid with a peculiar odor reminiscent of geranium leaves. The technical product is a dark brown liquid. Density = 1.88 g/cm3 (20°C). Air vapor density = 7.2. It is highly soluble in organic solvents, solubility in water is only 0.05% (at 20°C). Melting point = -15°C, boiling point = about 190°C (dec.). Vapor pressure at 20°C 0.39 mm. rt. Art.

    Toxicological properties:
    Lewisite, unlike mustard gas, has almost no period of latent action: signs of damage to it appear within 2-5 minutes after entering the body. the severity of the damage depends on the dose and time spent in an atmosphere contaminated with mustard gas. When inhaling lewisite vapor or aerosol, the upper respiratory tract is primarily affected, which manifests itself after a short period of latent action in the form of coughing, sneezing, and nasal discharge. In case of mild poisoning, these phenomena disappear within a few hours, in case of severe poisoning, they continue for several days. severe poisoning is accompanied by nausea, headaches, loss of voice, vomiting, and general malaise. Subsequently, bronchopneumonia develops. Shortness of breath and chest cramps are signs of very severe poisoning, which can be fatal. Signs of approaching death are convulsions and paralysis. LCt50 = 1.3 mg min/l.

    Hydrocyanic acid (cyanchloride)

    Hydrocyanic acid (HCN) is a colorless liquid with the smell of bitter almonds, boiling point + 25.7. C, freezing temperature -13.4. C, vapor density in air 0.947. Easily penetrates into porous building materials, wood products, and is adsorbed by many food products. Transported and stored in liquid state. A mixture of hydrocyanic acid vapor and air (6:400) may explode. The force of the explosion exceeds TNT.

    In industry, hydrocyanic acid is used for the production of organic glass, rubbers, fibers, orlan and nitron, pesticides.

    Hydrocyanic acid enters the human body through the respiratory system, with water, food and through the skin.

    The mechanism of action of hydrocyanic acid on the human body is the disruption of intracellular and tissue respiration due to suppression of the activity of iron-containing tissue enzymes.

    Molecular oxygen from the lungs to the tissues is supplied by blood hemoglobin in the form of a complex compound with the iron ion Hb (Fe2+) O2. In tissues, oxygen is hydrogenated into a group (OH), and then interacts with the enzyme citrochromoxidase, which is a complex protein with the iron ion Fe2+ The Fe2+ ion gives oxygen an electron, autoxidizes into the Fe3+ ion and binds to the group (OH)

    This is how oxygen is transferred from the blood to the tissues. Subsequently, oxygen participates in the oxidative processes of the tissue, and the Fe3+ ion, having accepted an electron from other cytochromes, is reduced into the Fe2+ ion, which is again ready to interact with blood hemoglobin.

    If hydrocyanic acid enters the tissue, it immediately interacts with the iron-containing enzyme group of cytochrome oxidase and at the moment the Fe3+ ion is formed, a cyanide group (CN) is added to it instead of a hydroxyl group (OH). Subsequently, the iron-containing group of the enzyme does not participate in the selection of oxygen from the blood. This is how cellular respiration is disrupted when hydrocyanic acid enters the human body. In this case, neither the flow of oxygen into the blood nor its transfer by hemoglobin to the tissues is impaired.

    Arterial blood is saturated with oxygen and passes into the veins, which is expressed in the bright pink color of the skin when affected by hydrocyanic acid.

    The greatest danger to the body is inhalation of hydrocyanic acid vapors, as they are carried by the blood throughout the body, causing suppression of oxidative reactions in all tissues. In this case, blood hemoglobin is not affected, since the Fe2+ ion of blood hemoglobin does not interact with the cyanide group.

    Mild poisoning is possible at a concentration of 0.04-0.05 mg/l and an action time of more than 1 hour. Signs of poisoning: smell of bitter almonds, metallic taste in the mouth, scratching in the throat.

    Moderate poisoning occurs at a concentration of 0.12 - 0.15 mg/l and an exposure of 30 - 60 minutes. To the above-mentioned symptoms are added a bright pink coloring of the mucous membranes and skin of the face, nausea, vomiting, general weakness increases, dizziness appears, coordination of movements is impaired, a slowdown in the heartbeat, and dilation of the pupils of the eyes are observed.

    Severe poisoning occurs at a concentration of 0.25 - 0.4 mg/l and an exposure of 5 - 10 minutes. They are accompanied by convulsions with complete loss of consciousness and cardiac arrhythmia. Then paralysis develops and breathing stops completely.

    The lethal concentration of hydrocyanic acid is considered to be 1.5 - 2 mg/l with an exposure of 1 minute or 70 mg per person when ingested with water or food.

    Chloropicrin

    Chloropicrin is a colorless, mobile liquid with a pungent odor. Boiling point - 112°C; density d20=1.6539. Poorly soluble in water (0.18% - 20C). Turns yellow in the light. It practically does not hydrolyze, decomposing only when heated in alcoholic solutions of silica. When heated to 400 - 500 C, it decomposes with the release of phosgene. A concentration of 0.01 mg/l causes irritation of the mucous membranes of the eyes and upper respiratory tract, which manifests itself in the form of pain in the eyes, lacrimation and painful cough. A concentration of 0.05 mg/l is intolerable and also causes nausea and vomiting. Subsequently, pulmonary edema and hemorrhages in the internal organs develop. Lethal concentration 20 mg/l with exposure 1 min. Nowadays, it is used in many countries to check the serviceability of gas masks and as a training agent. Protection against chloropicrin - gas mask. Chloropicrin can be produced as follows: Picric acid and water are added to lime. This whole mass is heated to 70-75° C. (steam). Cools to 25° C. Instead of lime, you can use sodium hydroxide. This is how we got a solution of calcium (or sodium) picrate. Then we get a solution of bleach. To do this, bleach and water are mixed. Then gradually add calcium picrate (or sodium) solution to the bleach solution. At the same time, the temperature rises, by heating we bring the temperature to 85 ° C, “holding” the temperature until the yellow color of the solution disappears (undecomposed picrate). The resulting chloropicrin is distilled with water vapor. Yield 75% of theoretical. Chloropicrin can also be prepared by the action of chlorine gas on a solution of sodium picrate:

    C6H2OH(NO2)3 +11Cl2+5H2O => 3CCl3NO2 +13HCl+3CO2

    Chloropicrin precipitates at the bottom. You can also obtain chloropicrin by the action of aqua regia on acetone.

    ******************

    Bromoacetone

    It was used in the First World War as part of "Be" gases and martonites. Currently not used as a poisonous substance.

    Physicochemical characteristics:

    Colorless liquid, practically insoluble in water, but soluble in alcohol and acetone. T.pl. = -54°C, bp. = 136°C with decomposition. Chemically low-resistant: prone to polymerization with the elimination of hydrogen bromide (stabilizer - magnesium oxide), unstable to detonation. Easily degassed with alcohol solutions of sodium sulfide. Chemically quite active: as a ketone it gives oximes, cyanohydrins; how halogen ketone reacts with alcohol alkalis to give oxyacetone, and with iodides it gives the highly tear-producing iodoacetone.

    Toxicological properties:

    Lachrymator. Minimum effective concentration = 0.001 mg/l. Intolerable concentration = 0.010 mg/l. At an air concentration of 0.56 mg/l, it can cause severe damage to the respiratory system.

  8. 1915 campaign - the beginning of the massive use of chemical weapons

    In January the Germans completed development of a new chemical projectile known as "T", a 15 cm artillery grenade with a high blasting effect and an irritant chemical (xylyl bromide), subsequently replaced by bromoacetone and bromoethyl ketone. At the end of January, the Germans used it at the front in left-bank Poland in the Bolimov region, but chemically unsuccessful, due to the low temperature and insufficient mass shooting.

    In January, the French sent their chemical 26-mm rifle grenades to the front, but left them unused for now, since the troops had not yet been trained and there were no means of defense yet.

    In February 1915, the Germans carried out a successful flamethrower attack near Verdun.

    In March, the French first used chemical 26mm rifle grenades (ethyl bromoacetone) and similar chemical hand grenades, both without any noticeable results, which was quite natural to begin with.

    On March 2, in the Dardanelles operation, the British fleet successfully used a smoke screen, under the protection of which the British minesweepers escaped from the fire of Turkish coastal artillery, which began to shoot them while working to catch mines in the strait itself.

    In April, at Nieuport in Flanders, the Germans first tested the effect of their “T” grenades, which contained a mixture of benzyl bromide and xylyl, as well as brominated ketones.

    April and May were marked by the first cases of the massive use of chemical weapons in the form of gas balloon attacks, which were already very noticeable for opponents: in the Western European theater, on April 22, near Ypres and in the Eastern European theater, on May 31, at Volya Shydlovskaya, in the Bolimov area.

    Both of these attacks, for the first time in a world war, showed with complete conviction to all participants in this war: 1) what real power the new weapon - chemical - possesses; 2) what broad capabilities (tactical and operational) are included in it; 3) what an extremely important importance for the success of its use is the careful special preparation and training of troops and the observance of special chemical discipline; 4) what is the importance of chemical and chemical means. It was after these attacks that the command of both warring sides began to practically resolve the issue of the combat use of chemical weapons on an appropriate scale and began organizing a chemical service in the army.

    Only after these attacks did both warring countries face the issue of gas masks in all its severity and breadth, which was complicated by the lack of experience in this area and the variety of chemical weapons that both sides began to use throughout the war.

    Article from the website "Chemical Troops"

    ********************************

    The first information about the impending gas attack came to the British army thanks to the testimony of a German deserter, who claimed that the German command intended to poison its enemy with a cloud of gas and that gas cylinders were already installed in the trenches. Nobody paid attention to his story because this whole operation seemed completely impossible.

    This story appeared in the intelligence report of the main headquarters and, as Auld says, was considered untrustworthy information. But the deserter’s testimony turned out to be truthful, and on the morning of April 22, under ideal conditions, the “gas method of war” was used for the first time. Details of the first gas attack are almost absent for the simple reason that the people who could tell about it lie all in the fields of Flanders, where poppies now bloom.

    The point chosen for the attack was in the north-eastern part of the Ypres Salient, at the point where the French and English fronts converged, heading south, and from where the trenches departed from the canal near Besinge.

    The right flank of the French was a regiment of Turkos, and the Canadians were on the left flank of the British. Auld describes the attack in the following words:

    “Try to imagine the sensations and position of the colored troops when they saw that a huge cloud of greenish-yellow gas was rising from the ground and slowly moving with the wind towards them, that the gas was spreading along the ground, filling every hole, every depression and flooding trenches and craters. First surprise, then horror and finally panic gripped the troops when the first clouds of smoke enveloped the entire area and left the people gasping in agony. Those who could move fled, trying, mostly in vain, to outrun the cloud chlorine, which inexorably pursued them."

    Naturally, the first feeling that the gas method of warfare inspired was horror. We find a stunning description of the impression of a gas attack in an article by O. S. Watkins (London).

    “After the bombing of the city of Ypres, which lasted from April 20 to 22,” writes Watkins, “poisonous gas suddenly appeared amid this chaos.

    "When we went out into the fresh air to rest a few minutes from the stuffy atmosphere of the trenches, our attention was attracted by very heavy firing in the north, where the French were occupying the front. Apparently a hot battle was going on, and we energetically began to explore the area with our field glasses, hoping to catch something new in the course of the battle.Then we saw a sight that made our hearts stop - the figures of people running in confusion through the fields.

    “The French have been broken through,” we cried. We couldn’t believe our eyes... We couldn’t believe what we heard from the fugitives: we attributed their words to a frustrated imagination: a greenish-gray cloud, descending on them, became yellow as it spread and scorched everything in its path. touched, causing the plants to die. Not even the most courageous man could resist such a danger.

    “French soldiers staggered among us, blinded, coughing, breathing heavily, with faces dark purple, silent from suffering, and behind them in the gas-poisoned trenches remained, as we learned, hundreds of their dying comrades. The impossible turned out to be just. .

    "This is the most evil, most criminal act I have ever seen."

    *****************************

    The first gas attack on the Eastern European theater in the Bolimov area near Wola Szydłowska.

    The target for the first gas attack in the Eastern European theater were units of the 2nd Russian Army, which, with its stubborn defense, blocked the path to Warsaw in December 1914 of the persistently advancing 9th Army of General. Mackensen. Tactically, the so-called Bolimovsky sector, in which the attack was carried out, provided benefits for the attackers, leading to the shortest highway routes to Warsaw and not requiring crossing the river. Ravka, since the Germans strengthened their positions on its eastern bank back in January 1915. The technical benefit was the almost complete absence of forests in the location of Russian troops, which made it possible to make the gas quite long-range. However, assessing the indicated advantages of the Germans, the Russians had a fairly dense defense here, as can be seen from the following grouping:

    14 Sib. page division, subordinate directly to Army Commander 2. defended the area from the mouth of the river. Nits to the target: high. 45.7, f. Constantius, having 55 Sib in the right combat sector. regiment (4 battalions, 7 artillery machine guns, 39 command personnel. 3730 bayonets and 129 unarmed) and on the left 53 Sib. regiment (4 battalions, 6 machine guns, 35 command personnel, 3,250 bayonets and 193 unarmed). 56 Sib. The regiment formed a divisional reserve in Chervona Niva, and the 54th was in the army reserve (Guzov). The division included 36 76-mm cannons, 10 122-l howitzers (L(, 8 piston guns, 8 152-l howitzers

  9. Asphyxiating and poisonous gases! (Memo to a soldier)

    Instructions for gas control and information about gas masks and other means and measures against asphyxiating and poisonous gases. Moscow 1917

    1. The Germans and their allies during this world war refused to comply with any established rules of warfare:

    Without declaring war and without any reason for it, they attacked Belgium and Luxembourg, that is, neutral states and occupied their lands; they shoot prisoners, finish off the wounded, shoot at orderlies, parliamentarians, dressing stations and hospitals, plunder on the seas, disguise soldiers for the purposes of reconnaissance and espionage, commit all kinds of atrocities in the form of terror, i.e., to instill terror in the inhabitants of the enemy, and resort to all means and measures to carry out their combat missions, although these means and measures of struggle would be prohibited by the rules of war and inhumane in reality; At the same time, they do not pay any attention to the blatant protests of all states, even non-belligerent ones. And from January 1915 they began to suffocate our soldiers with suffocating and poisonous gases.

    2. Therefore, willy-nilly, we have to act on the enemy with the same means of struggle and, on the other hand, counter these phenomena with meaning, without unnecessary fuss.

    3. Asphyxiating and poisonous gases can be very useful when smoking the enemy out of his trenches, dugouts and fortifications, since they are heavier than air and penetrate there even through small holes and cracks. Gases now make up the weapons of our troops, like a rifle, a machine gun, cartridges, hand bombs and grenades, bomb throwers, mortars and artillery.

    4. You must learn to reliably and quickly put on your existing mask with goggles and deftly release gases at the enemy with calculation, if you are instructed to do so. In this case, it is necessary to take into account the direction and strength of the wind and the relative location of local objects from each other, so that the gases would certainly be carried by it, the wind, to the enemy or to the desired desired location of his positions.

    5. As a result of what has been said, you must carefully study the rules for releasing gases from vessels and develop the skill of quickly choosing a convenient position in relation to the enemy for this purpose.

    6. The enemy can be attacked with gases using artillery, bomb throwers, mortars, airplanes and hand bombs and grenades; then, if you act manually, that is, release gases from the vessels, you need to coordinate with them, as you were taught, in order to inflict the greatest possible defeat on the enemy.

    7. If you are sent on patrol to the dressing room, to protect the flanks or for some other purpose, then take care of the vessels with gases and hand grenades with gas filling given to you along with cartridges, and when the right moment comes, then use up and use their effect properly, at the same time we must keep in mind so as not to harm the action of our troops by poisoning the space from our position to the enemy, especially if we ourselves have to attack him or go on the attack.

    8. If a vessel with gases accidentally bursts or is damaged, then do not get lost, immediately put on your mask and warn neighbors who may be in danger with your voice, signals and conventional signs about the disaster that has occurred.

    9. You will find yourself on the front line of the position, in the trenches, and you will be the commander of a known sector, do not forget to study the terrain in front, on the sides and in the rear and outline, if necessary, and prepare a position for launching a gas attack on the enemy with the release of gases in significant quantities on that case, if weather conditions and wind direction allow it and your superiors will order you to take part in a gas attack on the enemy.

    10. Conditions that are more favorable for the release of gases are the following: 1) A smooth, weak wind blowing towards the enemy at a speed of 1-4 meters per second; a) dry weather with a temperature not lower than 5-10° and not too high, depending on the composition of the gases being circulated; H) a relatively elevated location with a convenient open slope towards the enemy’s side for launching a gas attack on him; 4) mild weather in winter, and moderate weather in spring, summer and autumn, and 5) during the day, the most favorable moments can be considered night time and morning at dawn, due to the fact that then most often there is a smooth, gentle wind, a more constant direction, and the influence of changing the outline of the surface of the earth surrounding your site and also the influence of the relative location of local objects on the direction of the wind, somehow; forests, buildings, houses, rivers, lakes and others must be studied immediately at the position. In winter the wind is generally stronger, in summer it is weaker; during the day it is also stronger than at night; in mountainous areas, in the summer, the wind blows into the mountains during the day, and from the mountains at night; Near lakes and the sea during the day, water flows from them to land, and at night, on the contrary, and in general other well-known certain phenomena are observed. You need to firmly remember and study everything mentioned here before launching a gas attack on the enemy.

    11. If the indicated favorable conditions for a one-time attack more or less present themselves to the enemy, then our troops must increase the vigilance of observation on the front lines and prepare to meet the enemy’s gas attack and immediately notify military units about the appearance of gases. Therefore, if then you are on patrol, secret, flank guard, reconnaissance, or a sentry in a trench, then immediately when gas appears, report this to your superiors and, if possible, simultaneously report to the observation post from the special team of chemists and its chief, if there are any in the part.

    12. The enemy uses gases released from vessels in the form of a continuous cloud spreading along the ground or in projectiles thrown by guns, bombers and mortars, or thrown from aircraft, or by throwing hand bombs and grenades with gas filling.

    13. Suffocating and poisonous gases released during a gas attack advance towards the trenches in the form of a cloud or fog of different colors (yellowish-green, bluish-gray, gray, etc.) or colorless, transparent; a cloud or fog (colored gases) moves in the direction and speed of the morning, in a layer up to several fathoms thick (7-8 fathoms), therefore it even covers tall trees and roofs of houses, which is why these local objects cannot save from the effects of gases. Therefore, do not waste your time climbing a tree or onto the roof of a house; if you can, take other measures against gases, which are indicated below. If there is a high hill nearby, occupy it with the permission of your superiors.

    14. Since the cloud rushes quite quickly, it is difficult to escape from it. Therefore, during an enemy gas attack, do not run away from him to your rear, it, the cloud, catches up with you, moreover, you remain in them longer and on the 6th stage you will inhale more gas into yourself due to increased breathing; and if you go forward, to attack, you will get out of the gas sooner.

    15. Suffocating and poisonous gases are heavier than air, stay closest to the ground and accumulate and linger in forests, hollows, ditches, pits, trenches, dugouts, communication passages, etc. Therefore, you cannot stay there unless absolutely necessary, and then only with the adoption of peace against gases

    16. These gases, touching a person, corrode the eyes, cause coughing and, getting into the throat in large quantities, choke him, which is why they are called suffocating gases or “Cain smoke.”

    17. They destroy animals, trees and grass just like humans. All metal objects and parts of weapons deteriorate from them and become covered with rust. Water in wells, streams and lakes where gas has passed through becomes unsafe for drinking for some time.

    18. Suffocating and poisonous gases are afraid of rain, snow, water, large forests and swamps, since they, capturing the gases, prevent their spread. Low temperature - cold also causes gases to spread, turning some of them into a liquid state and causing them to fall in the form of small droplets of mist.

    19. The enemy releases gases mainly at night and before dawn and for the most part in successive waves, with breaks between them of about half an hour to an hour; Moreover, in dry weather and with a weak wind blowing in our direction. Therefore, then be prepared to meet such gas waves and check your mask to ensure that it is in good working order and other materials and means to meet a gas attack. Inspect the mask daily and, if necessary, repair it immediately or report for replacement with a new one.

    20. You will teach how to correctly and quickly put on the mask and glasses that you have, carefully arrange them and store them carefully; and practice putting on masks quickly using training masks, or homemade ones, if possible (wet masks).

    21. Fit the mask well to your face. If you have a wet mask, then in the cold hide the mask and bottles with a supply of solution so that they do not suffer from the cold, for which you put the bottles in your pocket or put a mouse with a mask and a rubber wrapper that prevents drying out and bottles of solution under your overcoat. Protect the mask and compress from drying out by carefully and tightly covering them with a rubber wrap or placing them in a rubber bag, if available.

    22. The first signs of the presence of gases and poisoning are: tickling in the nose, a sweet taste in the mouth, the smell of chlorine, dizziness, vomiting, plugging of the throat, cough, sometimes stained with blood and with severe pain in the chest, etc. If you notice anything like this in yourself, immediately put on a mask.

    23. The poisoned (comrade) must be placed in the fresh air and given milk to drink, and the paramedic will give the necessary means to maintain the activity of the heart; he should not be allowed to walk or move unnecessarily and generally require complete calm from him.

    24. When gases are released by the enemy and they are approaching you, then quickly, without fuss, put on a wet mask with goggles, or a dry Kummant-Zelinsky mask, a foreign one, or some other approved model, according to the orders and commands of the superior. If gases penetrate through the mask, press the mask tightly to your face, and wet the wet mask with a solution, water (urine) or other anti-gas liquid.

    25. If wetting and adjusting do not help, then cover the mask with a wet towel, scarf or rag, wet hay, fresh damp grass, moss. and so on, without removing the mask.

    26. Make yourself a training mask and adapt it so that, if necessary, it could replace the real one; You should also always have a needle, thread, and a supply of rags or gauze with you to repair the mask, if necessary.

    27. The Kummant-Zelinsky mask consists of a tin box with a dry gas mask inside and a rubber mask with goggles; the latter is placed above the top lid of the box and closed with a cap. Before putting this one on. masks, do not forget to open the bottom cover (old Moscow model) or the plug in it (Petrograd model and new Moscow model), blow the dust out of it and wipe the glasses for the eyes; and when putting on a cap, adjust the mask and glasses more comfortably so as not to spoil them. This mask covers the entire face and even the ears.

    28. If it happens that you do not have a mask or it has become unusable, immediately report this to your senior manager, team or boss and immediately ask for a new one.

    28. In battle, do not disdain the enemy’s mask, get them for yourself in the form of spare ones, and if necessary, use them for yourself, especially since the enemy releases gases in successive waves.

    29. The German dry mask consists of a rubberized or rubber mask with a metal bottom and a screwed hole in the middle of the latter, into which a small conical tin box is screwed in with its screwed neck; and inside the box a dry gas mask is placed, moreover, the bottom cover (of the new model) can be opened to replace the last one, the gas mask, with a new one. For each mask there are 2-3 numbers of such boxes with different gas masks, against one or another corresponding type of gas, and at the same time they also serve as spare ones as needed. These masks do not cover the ears like our masks. The entire mask with a gas mask is enclosed in a special metal box in the form of a cooking pot and as if it serves a dual purpose.

    30. If you don’t have a mask or your mask is faulty and you notice a cloud of gases coming towards you, then quickly calculate the direction and speed of the gases moving with the wind and try to adapt to the terrain. If the situation and circumstances allow, with the permission of your superiors, you can move slightly to the right, left, forward or backward to occupy a more elevated area or a convenient object in order to evade to the side or escape from the sphere of the advancing gas wave, and after the danger has passed, immediately take your previous place.

    32. Before the movement of gases, light a fire and put on it everything that can give a lot of smoke, such as damp straw, pine, spruce branches, juniper, shavings doused with kerosene, etc., since gases are afraid of smoke and heat and turn to the side away from the fire and go up, to the rear, through it or partly are absorbed by it. If you or several people are separated, then surround yourself with fires on all sides.

    If it is possible and there is enough combustible material, then lay out first a dry, hot fire in the direction of the movement of gases, and then a wet, smoky or cold fire, and between them it is advisable to place a barrier in the form of a dense fence, tents or wall. In the same way, on the other side of the wall there is a cold fire and immediately, not far behind it, on this side a hot fire. Then the gases are partly absorbed by the cold fire, hitting the ground, rise upward and the hot fire further contributes to raising them to a height and, as a result, the remaining gases, together with the upper jets, are carried to the rear in the morning. You can first place a hot fire, and then a cold one, then the gases are neutralized in the reverse order, according to the indicated properties of the same fire. It is also necessary to make such fires during a gas attack and in front of the trenches.

    33. Surrounding you: behind the fires you can spray the air with water or a special solution and thereby destroy any gas particles that accidentally get there. To do this, use buckets with a broom, watering cans or special, special sprayers and pumps of various types.

    34. Moisten the towel, handkerchief, rags, headband yourself and tie it tightly around your face. Wrap your head well in an overcoat, shirt or tent flap, having previously moistened them with water or gas mask liquid and wait until the gases pass, while trying to breathe as smoothly as possible and remain as completely calm as possible.

    35. You can also bury yourself in a pile of hay and wet straw, stick your head into a large bag filled with fresh wet grass, charcoal, wet sawdust, etc. It is not forbidden to go into a strong, well-built dugout and close the doors and windows, if possible , anti-gas materials, wait until the gases are driven away by the wind.

    36. Don’t run, don’t scream, and generally be calm, because excitement and fussiness make you breathe harder and more often, and gases can enter your throat and lungs more easily and in larger quantities, i.e., they begin to choke you.

    37. Gases stay in the trenches for a long time, which is why you can’t immediately take off your masks and stay in them after the main masses of gases have left, until the trenches and dugouts or other premises are ventilated, refreshed and disinfected by spraying or other means.

    38. Do not drink water from wells, streams and lakes in areas where gases have passed through, without the permission of your superiors, since it may still be poisoned by these gases.

    39. If the enemy advances during a gas attack, immediately open fire on him by order or independently, depending on the situation, and immediately let the artillery and surroundings know about this, so that they can support the attacked area in time. Do the same when you notice that the enemy is starting to release gas.

    40. During a gas attack on your neighbors, assist them in any way you can; if you are the commander, then order your people to take an advantageous flank position in case the enemy goes on the attack on neighboring areas, hitting him in the flank and from the rear, and also be ready to rush at him with bayonets.
    41. Remember that the Tsar and the Motherland do not need your death in vain, and if you had to sacrifice yourself on the altar of the Fatherland, then such a sacrifice should be completely meaningful and reasonable; therefore, take care of your life and health from the treacherous “Cain’s smoke”, the common enemy of humanity in all your understanding, and know that they are dear to the Motherland of Mother Russia for the benefit of serving the Tsar-Father and for the joy and consolation of our future generations.

  10. The first gas attack by Russian troops in the Smorgon region on September 5-6, 1916

    Scheme. Gas attack of the Germans near Smorgon in 1916 on August 24 by Russian troops

    For a gas attack from the front of the 2nd Infantry Division, a section of the enemy position from the river was chosen. Viliya near the village of Perevozy to the village of Borovaya Mill, a length of 2 km. The enemy trenches in this area look like an outgoing almost right angle with the apex at a height of 72.9. The gas was released over a distance of 1100 m in such a way that the center of the gas wave fell against the 72.9 mark and flooded the most protruding part of the German trenches. Smoke screens were placed on the sides of the gas wave up to the boundaries of the intended area. The amount of gas is calculated for 40 minutes. launch, for which 1,700 small cylinders and 500 large, or 2,025 pounds of liquefied gas were brought in, which gives about 60 pounds of gas per kilometer per minute. Meteorological reconnaissance in the selected area began on August 5.

    At the beginning of August, training of variable personnel and preparation of trenches began. In the first line of trenches, 129 niches were built to accommodate cylinders; for ease of control of gas release, the front was divided into four uniform sections; Behind the second line of the prepared area, four dugouts (warehouses) are equipped for storing cylinders, and from each of them a wide communication path is laid out to the first line. Upon completion of preparations, on the nights of September 3-4 and 4-5, cylinders and all special equipment necessary for releasing gases were transported to storage dugouts.

    At 12 noon on September 5, at the first sign of a favorable wind, the head of the 5th chemical team asked permission to carry out an attack the following night. From 16:00 on September 5, meteorological observations confirmed the hope that conditions would be favorable for gas release at night, as a steady south-east wind blew. At 16:45 permission was received from army headquarters to release the gas, and the chemical team began preparatory work on equipping the cylinders. Since that time, meteorological observations have become more frequent: up to 2 o'clock they were made every hour, from 22 o'clock - every half hour, from 2 o'clock 30 minutes. September 6 - every 15 minutes, and from 3 hours 15 minutes. and during the entire release of gas, the control station conducted observations continuously.

    The observation results were as follows: by 0 h 40 min. On September 6, the wind began to subside at 2:20 a.m. - intensified and reached 1 m, at 2 hours 45 minutes. - up to 1.06 m, at 3 o’clock the wind increased to 1.8 m, by 3 o’clock 30 min. The wind force reached 2 m per second.

    The wind direction was invariably from the southeast, and it was even. Cloudiness was assessed as 2 points, clouds were highly stratified, pressure was 752 mm, temperature was 12 PS, humidity was 10 mm per 1 m3.

    At 22:00, the transfer of cylinders from warehouses to the front lines began with the help of the 3rd battalion of the 5th Kaluga Infantry Regiment. At 2:20 a.m. transfer completed. Around the same time, final permission was received from the division chief to release gas.

    At 2:50 On September 6, the secrets were removed, and the communication passages to their places were blocked with previously prepared bags of earth. At 3:20 a.m. all the people wore masks. At 3:30 a.m. Gas was released simultaneously along the entire front of the selected area, and smoke screen bombs were lit on the flanks of the latter. The gas, escaping from the cylinders, first rose high and, gradually settling, crawled into the enemy trenches in a solid wall 2 to 3 m high. During the entire preparatory work, the enemy did not show any signs of himself, and before the start of the gas attack, not a single shot was fired from his side.

    At 3 hours 33 minutes, i.e. after 3 minutes. After the start of the Russian attack, three red rockets were launched in the rear of the attacked enemy, illuminating a cloud of gas that was already approaching the enemy’s forward trenches. At the same time, fires were lit on the right and left of the attacked area and rare rifle and machine-gun fire was opened, which soon, however, stopped. 7-8 minutes after the start of gas release, the enemy opened heavy bombing, mortar and artillery fire on the Russian forward lines. The Russian artillery immediately opened energetic fire on the enemy batteries, and between 3 hours and 35 minutes. and 4 hours 15 minutes. all eight enemy batteries were silenced. Some batteries fell silent after 10-12 minutes, but the longest period of time to achieve silence was 25 minutes. The fire was carried out mainly with chemical shells, and during this time the Russian batteries fired from 20 to 93 chemical shells each [The fight against the German mortars and bombs began only after the release of the gas; by 4:30 their fire was suppressed.].

    At 3:42 a.m. An unexpected gust of eastern wind caused a gas wave that reached the left flank of the river. Oksny shifted to the left, and, having crossed Oksna, it flooded the enemy’s trenches north-west of the Borovaya Mill. The enemy immediately raised a strong alarm there, the sounds of horns and drums were heard, and a small number of fires were lit. With the same gust of wind, the wave moved along the Russian trenches, capturing part of the trenches themselves in the third section, which is why the release of gas here was immediately stopped. They immediately began to neutralize the gas that had entered their trenches; in other areas the release continued, as the wind quickly corrected itself and again took a south-easterly direction.

    In the minutes that followed, two enemy mines and fragments of a close-exploding shell hit the trenches of the same 3rd section, which destroyed two dugouts and one niche with cylinders - 3 cylinders were completely broken, and 3 were badly damaged. The gas escaping from the cylinders, without having time to spray, burned people who were near the gas battery. The gas concentration in the trench was very high; the gauze masks completely dried out, and the rubber in the Zelinsky-Kummant respirators burst. The need to take emergency measures to clear the trenches of the 3rd section forced at 3 hours 46 minutes. stop releasing gas along the entire front, despite continued favorable meteorological conditions. Thus, the entire attack lasted only 15 minutes.

    Observations revealed that the entire area planned for the attack was affected by gases, in addition, the trenches north-west of the Borovaya Mill were affected by gases; in the valley northwest of mark 72.9, the remains of the gas cloud were visible until 6 o'clock. In total, gas was released from 977 small cylinders and from 65 large ones, or 13 tons of gas, which gives about 1 ton of gas per minute per 1 km.

    At 4:20 a.m. began cleaning the cylinders into warehouses, and by 9:50 a.m. all property had already been removed without any interference from the enemy. Due to the fact that there was still a lot of gas between the Russian and enemy trenches, only small parties were sent for reconnaissance, met with rare rifle fire from the front of the gas attack and heavy machine-gun fire from the flanks. Confusion was found in the enemy trenches, groans, screams and burning straw were heard.

    In general, the gas attack should be considered a success: it was unexpected for the enemy, since only after 3 minutes. The lighting of fires began, and then only against the smoke screen, and at the front of the attack they were lit even later. Screams and groans in the trenches, weak rifle fire from the front of the gas attack, increased work by the enemy to clear the trenches the next day, the silence of the batteries until the evening of September 7 - all this indicated that the attack caused the damage that could be expected from the quantity released gas This attack indicates the attention that must be given to the task of fighting the enemy's artillery, as well as his mortars and bombs. The fire of the latter can significantly hinder the success of a gas attack and cause poisoned losses among the attackers themselves. Experience shows that good shooting with chemical shells greatly facilitates this fight and leads to rapid success. In addition, the neutralization of gas in one's trenches (as a result of unfavorable accidents) must be carefully thought out and everything necessary for this must be prepared in advance.

    Subsequently, gas attacks in the Russian theater continued on both sides until the winter, and some of them are very indicative in terms of the influence that relief and meteorological conditions have on the combat use of BKV. So, on September 22, under the cover of thick morning fog, the Germans launched a gas attack on the front of the 2nd Siberian Rifle Division in the area south-west of Lake Naroch

  11. Yes, here you have production instructions:

    "You can produce chloropicrin as follows: Add picric acid and water to lime. This whole mass is heated to 70-75° C. (steam). Cooled to 25° C. Instead of lime, you can take sodium hydroxide. This is how we got a solution of calcium picrate (or sodium). Then a solution of bleach is obtained. To do this, bleach and water are mixed. Then a solution of calcium picrate (or sodium) is gradually added to the bleach solution. At the same time, the temperature rises, by heating we bring the temperature to 85 ° C, " We maintain the temperature until the yellow color of the solution disappears (undecomposed picrate). The resulting chloropicrin is distilled with water vapor. The yield is 75% of the theoretical. You can also obtain chloropicrin by the action of chlorine gas on a solution of sodium picrate:
