In Occupied France… A major raid by mainly Canadian Forces (2nd Canadian Division, under General Roberts), with a British commando component (Nos. 3 & 4 commandos under Lord Lovat) and 50 American Rangers, is staged on the French coast, at Dieppe. Its function is to test German coastal defenses and gather intelligence. The raid goes badly and there is much controversy about it, including the cancellation and remounting of the raid, the inaccurate intelligence concerning German defensive positions and the lack of bomber support for the raid. In all there are 3600 casualties on the Allied side. 106 aircraft, one destroyer, 30 tanks and 33 landing craft are also lost. German casualties are light, 600 men and 50 tanks.
