The Battle of Vimy Ridge, during the First World War, is Canada's most celebrated military victory — a sometimes mythologized symbol of the birth of Canadian national pride and awareness. The four divisions of the Canadian Corps, fighting together for the first time, attacked the ridge from 9 to 12 April, 1917 and succeeded in capturing it from the German army. More than 10,500 Canadians were killed and wounded in the assault.

Vimy also became emblematic of Canada's overall sacrifices in the First World War — especially its 60,000 war dead — sacrifices that convinced Prime Minister Robert Borden to step out of Britain's shadow and push for separate representation for Canada and the other Dominions at the Paris peace talks after the war.

Today an iconic white memorial atop the ridge commemorates the battle and honours the 11,285 Canadians killed in France throughout the war who have no known graves.
