With so many fire-support landing craft, why did the assault on Omaha Beach begin so badly?
Short answerThe beach's geography strongly favoured the defence, and the assault needed more effective firepower and possibly more tracked landing vehicles.
NotesOmaha was strategically important because of the wider invasion geography, but its local terrain made it the worst assault beach. Swimming tanks alone do not explain the failure. More LVT-type tracked vehicles might have helped troops cross the beach, but the defenders also required a greater weight of effective fire.
