They had been fighting for up to four years abroad and considered that it was now the turn of others, especially those divisions which had not yet been committed in any theatre. A number of former Eighth Army regiments had not been home for six years, and one or two had been away for even longer. Their resentment was strongly influenced by wives and girlfriends at home.

The US 1st Division, known as the ‘Big Red One’, also grumbled when picked yet again to lead the way in a beach assault, but its experience was badly needed. A major assessment report on 8 May had rated almost every other American formation allocated to the invasion as ‘unsatisfactory’. American senior officers were stung into action and the last few weeks of intensive training were not wasted. Eisenhower was encouraged by the dramatic improvement, and privately grateful for the decision to postpone the invasion from early May to early June.

There were other tensions in the Allied command structure. Eisenhower’s deputy supreme commander, Air Chief Marshal Sir Arthur Tedder, loathed Montgomery, but he in turn was deeply disliked by Winston Churchill. General Omar Bradley, the commander of the First US Army, who came from poor Missouri farming stock, did not look very martial with his ‘hayseed expression’ and his government-issue spectacles. But Bradley was ‘pragmatic, unruffled, apparently unambitious, somewhat dull, neither flamboyant nor ostentatious, and he never raised hackles’. He was also a shrewd commander, driven by the need to get the job done. He was outwardly respectful towards Montgomery, but could not have been less like him.

Bradley got on very well with Eisenhower, but he did not share his chief’s tolerance towards that loose cannon, George Patton. In fact Bradley barely managed to conceal his intense distrust of that eccentric southern cavalryman.
