It's been 100 years since Canadian soldiers conquered the "grey mountainous mass of mud" known as Vimy Ridge, which other armies had tried and failed to take. For the first time, all four of Canada's divisions would attack as one, taking a tactical victory. The four-day onslaught in France would steal the lives of 3,600 Canadians. The Agenda convenes a panel of experts to analyze the battle, where it fit on the path toward an Allied victory in the First World War, and on Canada's path toward nationhood. The Agenda also looks at the place Vimy occupies within Canada's historical memory, and to what extent it might have been mythologized.
