Patton, a God-fearing man famous for his profanity, enjoyed addressing his troops in provocative terms. ‘Now I want you to remember,’ he once told them, ‘that no bastard ever won a war by dying for his country. You win it by making the other poor dumb bastard die for his country. ’There is no doubt that with out Eisenhower’s support at critical moments, Patton would never have had the chance to make his name in the coming campaign. Eisenhower’s ability to keep such a disparate team together was an extraordinary achievement.

The most recent dispute produced entirely by D-Day jitters came from Air Chief Marshal Leigh-Mallory. Leigh-Mallory, who ‘made everyone angry’ and even managed to rile Eisenhower, suddenly became convinced that the two US airborne divisions due to be dropped on the Cotentin peninsula faced a massacre. He repeatedly urged the cancellation of this vital element in the Overlord plan to protect the western flank. Eisenhower told Leigh-Mallory to put his concerns in writing. This he did, and after careful consideration Eisenhower rejected them with Montgomery’s full support.

Eisenhower, despite his nervous state and the appalling responsibility heaped upon him, wisely adopted a philosophical attitude. He had been selected to make the final decisions, so make them he must and face the consequences. The biggest decision, as he knew only too well, was almost upon him. Quite literally, the fate of many thousands of his soldiers’ lives rested upon it. Without telling even his closest aides, Eisenhower prepared a brief statement to be made in the event of failure: ‘The landings in the Cherbourg-Havre area have failed to gain a satisfactory foothold and I have withdrawn the troops. My decision to attack at this time and place was based on the best information available. The troops, the air and navy did all that bravery and devotion to duty could do. If any blame or fault attaches to the attempt it is mine alone.’
