Gas at Ypres

22 Apr 1915 — A green-yellow chlorine cloud rolls over French colonial troops at Langemarck: the first mass poison-gas attack. By 1918 gas has killed some 90,000 and maimed a million more. Remember what industrial chemistry did here.
This is one scene of Chapter 4 — The Widening War in The Great War, 1914–1918.
