What if the enemy forces were far stronger than expected? What if reinforcements arrived more quickly or in greater strength? What if the new technologies developed for D-Day failed? And what about the weather? No general can control that.ĭ-Day was a critical step in ending the war. When the first bullets flew, when the first boots hit the ground, he would have known that so much could have gone wrong. Now, like Eisenhower, I have sent men on life-threatening operations and I know what Eisenhower knew that no plan, however well thought through, survives first contact with the enemy. He had been planning for this moment for over a year. The man in overall command was US General Dwight D. If the invasion was successful, the battle to defeat Hitler would follow. But on D-Day it was one of the first ships of the British and Allied invasion force that unleashed fury on the forces of Nazi Germany that lay just across the Channel. Nowadays, this vast ship, HMS Belfast, is moored by the banks of the River Thames in London. In the early hours of the 6th June 1944, these huge guns opened fire on the coast of northern France.
