The losses at Dieppe were claimed to be a necessary evil. Mountbatten later justified the raid by arguing that lessons learned at Dieppe in 1942 were put to good use later in the war. He later claimed, "I have no doubt that the Battle of Normandy was won on the beaches of Dieppe. For every man who died in Dieppe, at least 10 more must have been spared in Normandy in 1944." In direct response to the raid on Dieppe, Churchill remarked that "My Impression of 'Jubilee' is that the results fully justified the heavy cost" and that it "was a Canadian contribution of the greatest significance to final victory."
