Dieppe is a fishing port on the Normandy coast built along a long cliff overlooking the English Channel. On 19 August 1942, Canadian, British, American, and Free French troops staged a raid against the German-occupied town and nearby seaside villages. The result was a disaster. In one morning, 3,367 Canadian soldiers were killed, wounded, or captured out of a force of 4,963 men. 907 Canadian soldiers died in the raid, making it Canada’s deadliest day of the Second World War.
Was the raid launched to appease American military leaders who sought action in 1942? To appease the Soviet leader, Joseph Stalin, whose forces were fighting desperately on the Eastern Front? To learn important lessons for the eventual landings that would come in June 1944? Today’s guest, David O’Keefe, offers a different purpose.
His research suggests that Combined Operations Headquarters, under Vice Admiral Lord Louis Mountbatten, designed the Dieppe Raid to steal secret German codebooks and materials. In early 1942, the German armed forces introduced the four-rotor Enigma cypher machine. Suddenly, signals intelligence (codenamed Ultra) the British and their allies relied upon to route convoys around German U-boats in the North Atlantic went dark. Sinkings skyrocketed. In their desperation to solve the problem, Combined Operations initiated Operation Jubilee. The result was a pathetic failure. Bravery could not overcome reckless planning.
