Throughout 1914, several uses of poison gas by the Allies went undetected by the Germans. At this stage, the ethyl bromoacetate the French were using as a tear gas was replaced by chloroacetone as bromine stocks were running low.
In early 1915, at the Battle of Bolimov, Germans fired 18, 000 shells filled with Xylyl Bromide, a tear gas. However, this failed as the liquid Xylyl Bromide froze, instead of forming a vapour. During June, 1915 the Second Battle of Ypres occurred, which marked the first major use of Chemical warfare by the Central Powers. Later in 1915, at the battle of Loos, the Allies first used chlorine at the Battle of Loos. However, poor wind conditions resulted in more Allied deaths than Central Power deaths. Around the same time, Phosgene was developed, which was 27 times more effective than chlorine and did not suffer from chlorine’s shortcomings. 1915 was also the year the Hypo-helmet was introduced, the first gas mask.
1917 marked the deployment of mustard gas at the Third Battle of Ypres. Mustard gas was used to harass Allied troops and lingered for days after it was deployed.
By 1918, the United States had developed Lewisite, a blistering agent, to use in 1919. However, the Armistice meant it was never used in battle, other than minor use by Japanese troops in World War II.
