A battle summary of Britain’s raid on the French port town of Dieppe during World War II.

Winston Churchill was under pressure. The Soviets felt that they were fighting the Germans by themselves. Stalin demanded Britain open a second front to draw German forces away from the east. Though the advice Churchill received from his staff was that an invasion of France would not be possible for at least another year, the British Prime Minister knew he had to do something to help the Russians.

The result was a large-scale raid upon the port of Dieppe, chosen as it was thought that the success of any invasion would depend on the capture of a major port to enable heavy weapons, vehicles, and reinforcements to be landed in support of the landing forces. It would not be the second front that Stalin wanted, but at least it would demonstrate Britain’s intent to support the Soviets. Plus, it provided a rehearsal for the eventual invasion.

The raid upon Dieppe, Operation Jubilee, was eventually scheduled for 19 August 1942. The assault was the most ambitious Allied attack against the German Channel defenses of the war so far, involving some 6,000 infantry, 237 naval vessels, and seventy-four squadrons of aircraft.

Though the debate surrounding Jubilee’s purpose and cost has raged in the years since the war, many vital and important lessons were learned. All these factors are covered in this official battle summary, a detailed and descriptive account of the Dieppe Raid, which was written shortly after the war and is based on the recollections of those who were involved.
