9. The Double Cross Pays Off
Juan Pujol’s carefully crafted lies, coupled with other Allied deception measures whereby a fictional First US Army Group, under the command of George Patton, was massed across the English Channel opposite the Pas de Calais, worked. The Germans were convinced during the crucial weeks of June, 1944, to keep powerful formations in that region, rather than rush them to Normandy to help destroy the vulnerable Allied beachhead.
By the time the Pas de Calais formations were finally released, it was too late. The Allies had amassed sufficient forces in Normandy to not only defeat German attacks, but to then go on the offensive, break out of the beachhead, and sweep across and liberate France within a few months.
