What Happened at Vancouver Corner?

In this episode we travel back to April 1915 and discover, through the eyes of the Canadian soldiers who were there, what happened when the Germans released chlorine gas at what is now called "Vancouver Corner". We look at the work of the Canadian architect and war veteran Frederick Clemesha who designed the "Brooding Soldier" memorial. How did the veterans view the memorial when they saw it years later? How did they stop the Germans from breaking through? And was a Canadian soldier really crucified during the battle?
