The significance of the D-Day landings lies in the fact that they represented a major turning point in the war. In retrospect, D-Day can be said to have marked the beginning of the end of World War II. Up until the Allied invasion of Normandy, the United States and Great Britain had been mainly concerned with slowing down the German advance in Europe. But now they were able to go on the offensive, taking the fight to Hitler's Germany in the lands it had occupied.
Once the Allies had successfully completed the invasion of Normandy, they were able to establish a firm foothold in Western Europe, leaving Hitler to face his worst nightmare: a war on two fronts. With the Allies making their way across France, the Germans now found themselves caught in a pincer movement between the Americans and the British in the West and the Soviet Union in the East.
D-Day had an enormous and immediate impact on German strategy. Hitler had no choice but to transfer whole divisions from Russia to France in order to meet the new Allied threat. But the damage had already been done. The D-Day landings had opened up a new front in the war, and the Germans lacked the resources, the manpower, and the logistics necessary to hold back the Allied tide.
D-Day is the World War II military operation which took place on June 6, 1944. It was code-named Operation Neptune, presumably because it involved a water landing by the Allies on the beaches of Normandy, France. It is the largest military operation by sea in history, and of course it had great significance to the war.
Before D-Day, the Germans were in the enviable position of only having to fight a war on one front: the eastern front, where the Russians were steadily encroaching on the territory Germany had won. Almost since the beginning of the war, Germany was in control of western Europe, so they had little fear of anything happening militarily from that direction.
D-Day changed everything. It is probably an exaggeration to say that the Normandy invasion was a turning point in the war, as the Allies had been making steady progress against the German forces for more than a year. What is fair to say is the tides turned against the German forces at Normandy, shortening the war and giving the Allies momentum on the continent of Europe.
In addition to that, the events that transpired on D-Day allowed the non-Russian Allies to be a presence in the war's end as well as to curtail Russia's encroachment any farther into western Europe. Even though Russia was aligned with the Allies, it was making significant progress in capturing territory farther and farther west. The presence of American, Canadian, and British troops served both to stop Germany from its goal of world domination and to keep Russia from gaining any more territory in Europe.
In addition to its military significance, D-Day was then and still is a matter of national pride. The accomplishment was staggering in its boldness. The Allied military coordinated this surprise attack which included the
landing of 24,000 British, US, and Canadian airborne troops shortly after midnight. Allied infantry and armoured divisions began landing on the coast of France starting at 06:30.
The fifty-mile stretch of beaches were swarming not only with troops but with armored vehicles, an astonishing feat, military or not--and even more arrived in the following days.
D-Day is commemorated as one of the significant landmark moments of World War II. The official D-Day Memorial is located in Bedford, Virginia, and the images of troops landing on the beaches of Normandy are now iconic. They symbolize a superior cause and the ability to do the impossible, and that is what makes D-Day significant.
