The man who never was

the long version

It is the story of a World II deception by the Allies intended to dupe the Third Reich in believing that a sea landing in the Mediterranean would be in Greece instead that in Sicily where in reality occurred later. They drop a dead man dressed as an officer and carrying maps and documents in Spain coast which was eventually found by German spies. Hitler was informed and believed the information. He ordered a section of his troops out of Sicily.
