As a deception intended to cover the 1943 Allied invasion of Sicily, two members of British intelligence obtained the body of Glyndwr Michael, a tramp who died from eating rat poison, dressed him as an officer of the Royal Marines and placed personal items on him identifying him as Captain (Acting Major) William Martin.
