What happened
In 1943 the Allies were about to invade Sicily, and anyone with a map could see it coming. So two British intelligence officers, Ewen Montagu and Charles Cholmondeley, set out to make Hitler look somewhere else, using a dead man.
They dressed him as "Major William Martin" of the Royal Marines and built him a life: a fiancée's photo (really an MI5 clerk), love letters, an unpaid ring bill and a stern letter from his bank about an overdraft of nearly £80.
Chained to his coat was a briefcase of fake top-secret letters pointing at Greece and Sardinia. On 30 April 1943 a submarine slipped him into the sea off Spain. The Spanish quietly opened the letters, and the Germans got copies.
Two weeks later Hitler said the "discovered Anglo-Saxon order" confirmed the attack would hit Sardinia and Greece. The man in the uniform was Glyndwr Michael, a poor Welshman who died alone in London. His name stayed secret until 1996.
