Description: It has been called the most controversial battle Canadians have ever fought. On Aug. 19, 1942, after nearly three years of waiting in England for a chance to fight, Canadian troops were sent to raid the French coast at Dieppe. But the Germans were ready for them, and the attack became a massacre. Of nearly 5,000 Canadians sent to Dieppe, only 2,000 returned. More than 60 years later, the operation remains divisive: was Dieppe an essential trial run for D-Day, or a shocking waste of lives?
