Fortitude

This declassified WWII report offers a detailed look at the Allied campaign to deceive the Nazis about the immanent attack on Normandy.

As the conflict in Europe wore on, the Germans braced for an amphibious assault on France. The only question was where and when the Allies would strike. This required an intricate misinformation campaign to throw the Nazis off the scent.

The objective of Operation Fortitude was to persuade the enemy that the long-awaited landings would take place in the Pas-de-Calais, and that any attack in Normandy would be nothing more than a diversionary feint that could be safely ignored. Hundreds of bogus agent reports were manufactured, an entire US Army Group was invented, false radio signals transmitted, and inflatable tanks, dummy bombers built of balsa wood and canvas landing craft were positioned where they could be photographed by the Luftwaffe.

The elaborate ruse suggested an imminent amphibious assault from Dover, across the shortest stretch of the English Channel. Operation Fortitude was an extraordinary success. In this volume, the classified official history of the entire operation, written by Roger Hesketh as head of the team of D-Day deception specialists, has been declassified and released.
