Major William Martin was a persona invented by British Military Intelligence for Operation Mincemeat, the Second World War deception plan that lured German forces to Greece prior to the Allied invasion of Sicily. Also known as "the man who never was", Martin's personal details were created to lend credence to the scheme, which involved a body, dressed as a British officer and carrying secret documents, to wash up on shores of neutral Spain, apparently the victim of an air crash. It was intended that these documents, containing information that suggested an Allied assault on Greece was planned, should fall into the hands of German intelligence.
