A Plan to Fool the Nazis
One of the truly remarkable stories of World War II concerns a ruse which was
perpetrated with such consummate skill that it saved the lives of many allied
troops and helped to shorten the war. The simple, bold, and ingenious subterfuge

MAN NEVER WAS. In short, the idea was to plant fallacious information concerning
the Allied invasion of Europe upon a dead officer, have his body recovered by 
agents who would transmit the false information to Germany, and then observe
the effects of the plan.
