April 22, 1915 at 5:00PM, near Ypres, in France, the Germans released 168 tons of chlorine gas against the French.
This use of poison gas in warfare was far from first, however; please see:
How Stuff Works. "How Biological and Chemical Warfare Works." 2002. (10 January 2003).
Roman Legions regularly used burning sulphur (SO2, SO3, H2S, H2SO4 (in rain/fog) to at least irritate, incapacitate, or at best, kill enemies in immobile situations; fortified towns, settlements against geographic barriers; islands, cliffs, bodies of water, etc.
Opinions differ as to whether the Legions developed poison gas themselves, or if their own survivors/allies reported how to use it after hard experience.
Similarly, opinions differ about the logistics and practicality of raw sulphur transport, and the (un)likelihood of a somewhat bulky (and nasty) material being cheerfully carried by a notoriously lightly-packed Legionnaire. It is possible that free, native, naturally-occurring sulphur deposits were scouted, as would have been other staples, like water, wood, game, etc., and if present, utilized, from a point upwind any immovable objective.
