D-Day (D-Day) The invasion of Normandy lasted from June 6, 1944 to August 1994. It brought great effects in World War II, but especially in Germany . It was a turning point in the war. The loss of D-Day caused the power of the German army to weaken, leading to its downfall during World War II. When the Americans and the Allies invaded Normandy, German military reserves were extremely low. The German leaders did not expect an attack that day and left the Normandy headquarters. “Confident that rough seas and heavy cloud cover had put off any invasion plans for a while, Rommel went to visit his family at their home in southern Germany. Furthermore, most of Rommel's command staff headed inland for a military conference” (The History Place), implying that they were not prepared to defend themselves against Allied forces. German leaders expected the arrival of the Americans and Allied forces, but did not expect any attack that day due to the great storm. Since the leaders decided to take a day off, they had to face the consequences when Germany had lost the battle. Furthermore, there were not enough people to defend Normandy. Since "many Germans believed that the massive Normandy landings were simply a feint to draw their reserves away from the Pas de Calais", (Richard J) responded by defending the Pas de Calais. Unfortunately for the Germans, the Normandy defenses collapsed due to lack of men because they assumed they were wrong. The Normandy invasion was not a distraction, so the Americans and the Allies managed to win the D-Day battle thanks to the Germans' meager reserves. The Germans didn't realize this until it was too late. Yet Hitler allowed no reinforcements. He “…did not believe that D-Day was the real American… at the center of the paper… and most of their officers were absent at the time. By the time the news arrived that there had been an invasion, it was too late and they lost the battle despite having many advanced technologies. This affected the upcoming battles because they were forced to change their tactics as the Allied forces continued to liberate the countries. They continued to cross the German borders, which led to the fall. Furthermore, the D-Day response contributed to their loss because many German officers were worried about the war and dented their confidence. Bottom line, when Germany lost D-Day, they started losing every battle as well. D-Day was the reason why the Germans began to lose power. Despite their efforts, they failed to win the battles against the three power formations because they were now too weak. Ultimately, the three teams defeated Germany and put an end to Nazi power.
