The operation was conducted by No. 10 (Inter-Allied) Commando, No. 12 Commando and the Special Boat Service, and took place on the Channel islands and the northern coast of France in December 1943. Most of the raids consisted of ten men of various ranks, carried by Motor Torpedo Boats and dories, except for one operation, which was an airborne landing.
