It was a turning point in the Second World War. As the Allies prepared to invade Sicily in 1943, they wanted to dupe the Germans into thinking that their attack would be aimed elsewhere.
To carry out the deception, a plan was concocted in which a body was dumped in the sea, to be discovered by Axis forces, carrying fake 'secret documents' suggesting the invasion would be staged in Greece, 500 miles away.
Incredibly, the trick worked and the diversion of German troops to Greece has been credited by historians with playing a major part in the success of the Sicily invasion. The episode was later immortalised in the 1956 film The Man Who Never Was.
