In 2003, the Government of Canada declared April 9 Vimy Ridge Day to honour and remember the Battle of Vimy Ridge, which took place from April 9-12, 1917. Commemorate this day in your classroom or library with At Vimy Ridge: Canada’s Greatest World War I Victory. Canadian children’s author Hugh Brewster honours the men who fought at Vimy Ridge — a pivotal World War I battle that many historians view as the battle that defined Canada as a nation — and those who gave their lives. This title is also available in French as La bataille de Vimy : l’exploit des Canadiens, avril 1917.
