Almost nothing went right for the Allies. Bad weather, poor timing, and surprising defenses all contributed to the almost massive failure, but the Allies prevailed, due to some costly mistakes by the Nazis as well. How did they do it? It all started after December 7, 1941, the attack on Pearl Harbor. On December 7, 1941, Japan attacked Pearl Harbor in Hawaii. Soon after, Germany and Italy declared war on the United States and vice versa. The next year, British and American forces were in talks of invading Europe, this would be a major task to complete. In the article “Timeline of D-Day,” it says British Officer “Lieutenant-General designated ‘COSSAC’, Chief of Staff to the Supreme Allied Commander (designate). Detailed planning for landing operation commences; Operation Overlord is born” (Shellburst).In 1944, Dwight Eisenhower was put as the leader of the whole op. Hitler, being Hitler, got ahold of this whole plan to invade, and set up defenses in Pas-de-Calais. Little did he know, the whole thing was a deception operation by the Allies. They wanted the Germans to believe their invasion target was Pas-de-Calais, whilst in reality, it was the beaches of Normandy.After the major deception plan, the main invasion was ready to commence. “On the morning of June 5, 1944, General Eisenhower gave the green light to Operation Overlord. Within hours, a whole fleet of 3,000+ landing craft, 2,500+ ships, and 500+ naval vessels were on their way to the beaches. It was originally intended for the ground invasion to take place on that night, but very bad weather postponed it to the next morning…” (Research Starters: D-Day). While the ground attack was pushed back until the morning, Airborne units were ready to attack. More than 800 aircraft, carrying paratroopers and gliders, deployed troops to land on the easternmost and westernmost beaches: Sword Beach and Utah Beach. It didn’t take long for them to perform their specific tasks, and within minutes, they had secured both beaches. The Airborne units were the main part of the invasion, and they completed their objective.In the morning, the ground units were ready for their attack. The ships fired artillery rounds onto the beach to give cover to their ground forces. When they landed, the Germans were caught by surprise, but they put up an extremely hard fight. The forces were set up to land on three different beaches: Gold Beach, Juno Beach, and Omaha Beach, the hardest fought and bloodiest beach of the five. The forces struggled on all three beaches, due to higher than expected German reinforcements. More than 10,000 Allied soldiers have been recorded killed in action or missing in action. On Utah Beach, the landing craft landed upwards of 2500 feet away from their initial landing zone. On Gold Beach, a large number of German reinforcements were set up there, along with mines and traps set up along the shore. Now on Omaha Beach, the battle was really fought. Allied forces initially thought there would be little to no German troops waiting, but they were heavily ambushed, and a lot of their landing craft were taken out before even arriving on shore. For the ones that did make it, once they opened the doors, the machine guns in the bunkers started firing, forcing the soldiers to jump over the side into the water. While some soldiers waited for the machine guns to reload, others tried running straight for the seawall. This bold move got them almost immediately killed and sent back into the water, making it turn a bloody red color. When the Allies got close enough to where the guns couldn’t reach them, they cleared the bunkers and secured Omaha Beach. This battle is what most people remember D-Day by. It’s made an appearance in movies, documentaries, and video games.
