Set in the context of the Dieppe raid as a whole, Will Fowler studies the contribution of No. 4 Commando and Operation Cauldron.

In August 1942, the Allies launched a raid against the German-held port of Dieppe on the French channel coast. It was largely a disaster, with the Canadian forces bearing the brunt of the catastrophe. However, it wasn't all a failure, and history has tended to overlook the role of 4 Commando, who, along with their US Ranger counterparts, landed and successfully disabled the German guns threatening the rest of the landings.

Their actions proved an excellent demonstration of the military adage “train hard, fight easy” and showed the advantage of proper operational planning and brilliant leadership. This controversial raid also included members of the Free French and it was the first time US land forces engaged the Germans on mainland Europe.

Allies at Dieppe evaluates how and why they achieved their objectives in this daring Commando raid of World War II.
