In 1914, a chemist named Fritz Haber began working with the German Army to develop a new weapon for trench warfare: chlorine gas. This was first used in April 1915, when German forces released 150 tons of chlorine gas against the French Army at a place called Ypres. The French soldiers saw yellow clouds with a strange smell moving toward them. At first, they thought it was just smoke, but soon they felt pain in their chests and throats.
Realizing it was a gas attack, the French soldiers retreated, leaving a gap in their defenses. However, the German Army was cautious about moving forward because they were worried the gas might harm their own troops. This hesitation allowed Canadian and British forces to step in and regain control before the Germans could take advantage of the situation. Chlorine gas was extremely dangerous, damaging the lungs and causing a painful death by suffocation.
When the British Army tried using gas on September 25, 1915, the wind changed direction, blowing the gas back toward their own soldiers. To solve this problem, in 1916, they started using gas shells with heavy artillery, which allowed them to launch gas attacks from a safer distance.
At first, Allied soldiers tried to protect themselves with simple cotton pads or handkerchiefs soaked in urine, as the ammonia could help neutralize the chlorine. As the war went on, they were given proper gas masks and special respirators to protect them from the harmful effects of gas.

**First World War — Technology — Chlorine Gas**
In 1914, a chemist named Fritz Haber offered his expertise to the German Army. He began experimenting with chlorine gas for use in trench warfare. In April 1915, 150 tons of chlorine gas were deployed by German forces against the French Army at Ypres. French soldiers observed yellow clouds with a distinctive smell drifting toward their trenches. Initially, they thought the Germans were using a smokescreen until they began experiencing chest pains and throat irritation.
As the reality of a gas attack set in, the French troops retreated, creating a gap in the Allied line. The German Army hesitated to advance due to concerns about the effects of the chlorine gas on their own troops, allowing Canadian and British forces to regain the position before the Germans could exploit the situation. Chlorine gas caused severe damage to the respiratory system, leading to a painful death by asphyxiation.
When the British Army launched a gas attack on September 25, 1915, the wind blew the gas back toward their own troops. This issue was addressed in 1916 with the introduction of gas shells used with heavy artillery, which improved the range of the attacks.
To counter gas attacks, Allied troops initially used cotton pad masks or handkerchiefs soaked in urine, as the ammonia helped neutralize the chlorine. As the war continued, soldiers were provided with gas masks and anti-asphyxiation respirators, which offered more effective protection against gas.
