Poison gas is made use of for the first time in the Battle of Bolimów during WW1 in 1915 by the German Army against Russia. The gas was xylyl bromide, a kind of tear gas, which however was rendered ineffective due to the cold, freezing weather.
Historical records confirm the event's significance as the war's first gas attack, predating the more infamous 1915 Ypres chlorine deployment, and it prompted rapid Allied gas mask development despite its ineffectiveness.
