Operation Copperhead

Operation Copperhead was a small military deception operation run by the British during the Second World War. It formed part of Operation Bodyguard, the cover plan for the invasion of Normandy in 1944, and was intended to mislead German intelligence as to the location of General Bernard Montgomery. The operation was conceived by Dudley Clarke in early 1944 after he watched the film Five Graves to Cairo. Following the war M. E. Clifton James wrote a book about the operation, I Was Monty's Double. It was later adapted into a film, with James in the lead role.
