During World War II, an Allied force of 7,000 men carry out a large daytime raid against German positions at the French seaport of Dieppe. Aided by tanks and aircraft, the commando force–made up of approximately 5,000 Canadians, 2,000 British soldiers, and a handful of American and Free French troops–gained a foothold on the beach in the face of a furious German defense. During nine hours of fighting, the Allies failed to destroy more than a handful of their targets and suffered the death of 3,600 men. More than 100 aircraft, a destroyer, 33 landing craft, and 30 tanks were also lost. Despite its high costs, the Dieppe raid provided valuable logistical information later used in planning the successful 1944 Allied landing at Normandy.
