Before Eisenhower & Montgomery could invade Sicily, they needed Hitler to think they weren’t invading Sicily. So, they needed a ruse, and what they tried—“Operation Mincemeat”—was fricking genius. First, they found a conveniently already-dead British body, handcuffed a briefcase to him containing fake papers implying the Allies would invade Greece, shot him out of the HMS Seraph, then let him float to the Spanish coast and get scooped up by the Nazis, who fell for it. A huge chunk of the German army was diverted thanks to the plot of “Weekend At Bernie’s.”
