Because the American generals blew off General Montgomery’s advice to use armor in assaulting the beach - Montgomery had the British Army develop specialized assault vehicles for D-Day and offered some to the American Army - they refused.

Because the American generals blew off General Montgomery’s advice to use armor in assaulting the beach

The Americans deployed 64 amphibian Shermans at Omaha beach. The British deployed 40 Churchills. Now, what was that advice again?
