Week 39: Gas on the Western Front - Baptism of Fire for Canada

At the beginning of the 2nd Battle of Ypres, the wind blows in a favourable direction; the wide spread use of chlorine gas has a devastating effect on the French troops. Even the Germans are surprised by it. The incredible sacrifice of the Canadian troops make it possible to defend Hill 60 in the end.
