The most audacious deception operation of WWII. On the 30th of April, 1943, the corpse of a 'Major Martin' washed up near the Spanish city of Huelva. On his body, Spanish officials found secret documents detailing an upcoming Allied invasion of Greece. This was the moment that the Axis powers had been waiting for, and the Germans began redirecting much-needed divisions to Greece and the Balkans. They would discover only too late that this was all an elaborate feint, conceived by British Intelligence to obscure the Allies' real target - Sicily. By mid-July, the Allies had landed in southern Italy and the liberation of Nazi-occupied Europe was well underway.

So how exactly did its architects create this complex web of misdirection and misinformation? And can it really be true that the success of the Sicily invasion came down to this one act of deception? In this Explainer episode, Dan takes us through the twists and turns of this audacious and unorthodox act of subterfuge.

Produced by Mariana Des Forges and edited by Dougal Patmore.
