In this episode we travel to Vimy Ridge and discover how the Canadian Divisions came together to storm the German defences on Easter Monday 1917. We talk to Canadian historian Samantha McCrae and she explains how a Canadian soldier was awarded the Victoria Cross for his brave actions, but was killed in the process. And how a medic gave his life treating the wounded. We also discover how the Canadians planned and executed the attack and why tunnels, a model of the battlefield, heavy artillery and even the weather played a part in their incredible success. What does this battle mean to Canadians today? We find out.
