Threats and losses: In pre-invasion briefings, troops were told there would be Allied bombing power preceding them and that the Germans would be largely obliterated and washed ashore, Citino said.
While there were aerial bombings, the impact was not as planned. Some of the B-24s and B-17s flying overhead missed their targets. German troops sprayed guns and mortars with clear views of the soldiers, stevedores, porters, and technical support charging the narrow stretch of beach. Men waded through rough, cold water from Allied landing crafts under withering heavy fire. The dangers continued with mines in the sand.
The scene was similarly gruesome for combat engineers moving in with Bangalore torpedoes to blow up obstacles. Meanwhile, amphibious tank operators tried to shield Allied infantry and medics came ashore to try to administer emergency care while facing counterattacks and navigating around the dead and wounded.
Impact: A fraction of those who landed reached the top of the bluff. Some company headcounts went to single digits. But the troops who helped secure Omaha and the five paths off the beach in the coming days cleared the way for massive tanks, fuel, food, and reinforcements important to the rest of the campaign.
