Initial German Experiments
During World War One, armies were constantly searching for new ways to break the unexpected stalemate of trench warfare.

In October 1914, during the capture of Neuve Chapelle, the Germans fired shells at the French containing a chemical irritant that caused violent fits of sneezing.

This tactic was considered uncivilized before the war, but necessity forced armies to develop and use poison gas.

Three months later, tear gas was first used by the Germans on the Eastern Front in liquid form contained in 15 cm shells fired against the Russians at Bolimov.

However, the experiment failed due to the freezing temperatures in Russia. Despite this setback, the Germans did not give up and tried again with an improved tear gas mix at Nieuport against the French in March 1915.
