Normandy and Aftermath
John Keegan illustrates how the D-day landings marked the beginning of the end of Germany's grip over Europe.
Until June 10th, 1944, the German defenders of Normandy still retained the chance of throwing the Allied invaders back into the sea. On that evening the British and Americans succeeded in consolidating their separate footholds into a continuous bridgehead. Thereafter they were safe from defeat in detail and vulnerable only to a major counter-attack. The Germans lacked the capacity to launch such a counter-attack until they rallied their forces from the rest of France - and that the Allies were determined to prevent them from doing.
