In May 1944, the Western Allies were finally prepared to deliver their greatest blow of the war, the long-delayed, cross-channel invasion of northern France, code-named Overlord. Gen. Dwight D. Eisenhower was supreme commander of the operation that ultimately involved the coordinated efforts of 12 nations.
After much deliberation, it was decided that the landings would take place on the long, sloping beaches of Normandy. There, the Allies would have the element of surprise. The German high command expected the attack to come in the Pas de Calais region, north of the river Seine where the English Channel is narrowest. It was here that Adolf Hitler had put the bulk of his panzer divisions after being tipped off by Allied undercover agents posing as German sympathizers that the invasion would take place in the Pas de Calais.
