The Dieppe Raid, also known as Operation Jubilee, was an Allied amphibious assault on the German-occupied port of Dieppe, France, on August 19, 1942, during World War II. The raid, primarily involving Canadian troops with British and American support, aimed to seize and hold the port for a short period, gathering intelligence and assessing German defenses. The operation, however, encountered heavy resistance from well-prepared German forces. The Allies suffered significant casualties and were forced to withdraw after several hours of intense fighting. While strategically unsuccessful, the Dieppe Raid provided valuable lessons regarding amphibious operations and German coastal defenses, which proved crucial in planning future Allied landings, such as the Normandy invasion.
