D-Day Deception Plans

Topic Summary

Everyone knew there would have to be an Allied invasion to liberate western Europe from Nazi control; that fact could not be kept a surprise. But where, when, and what forces had to be secret if there would be any hope for success. The Allied forces were greatly outnumbered—some reports say 10:1—by Hitler’s Nazi armies who had already built a great “Atlantic Wall” of military obstacles and reinforcements all along the Atlantic coast line.  It was obvious to Hitler that the most advantageous invasion site for the Allies would be Pas de Calais, France because of its proximity to Dover, England. If the Calais ports were taken, they would provide Allied troops a place to quickly deport soldiers and supplies, and access the established French highways to make a straight-line to Hitler’s Germany.

    Knowing all this, the Allied forces began strategizing how to successfully invade. A complex web of deception plans was created to simultaneously be carried out and mislead Hitler’s Nazi forces. Bodyguard was the codename chosen for the overall strategy to protect the invasion. Operation Bodyguard included many deception plans to keep the Nazi forces spread out and guessing where and when the Allies would invade western Europe.
