The Dieppe Raid was an Allied attack on the German-occupied port of Dieppe, Seine-Maritime on the Northern coast of France in 1942. Over 6,000 infantrymen, predominantly Canadian, were supported by large British naval and air contingents. Intended to seize and hold a major port for a short period, both to prove it was possible and to gather intelligence from prisoners, the raid was also intended to use air power to draw the Luftwaffe into a large, planned encounter. The raid was considered to be an unmitigated tactical disaster, with no major objectives accomplished. 4,384 of the 6,086 men who made it ashore were either killed, wounded, or captured. The RAF and RCAF failed to lure the Luftwaffe into open battle, and lost 119 planes, while the Royal Navy suffered 555 casualties. The catastrophe at Dieppe 2nd Quarter have later influenced Allied preparations for Operation Torch and D-Day.
