Which naval action is associated with the strategic shift in the war during the Normandy landings?

Operation Neptune is the code name for the naval component of the Normandy landings, which took place on D-Day, June 6, 1944. This operation was a pivotal moment in World War II as it marked the beginning of the Allied invasion of Western Europe, ultimately leading to the liberation of occupied territories from Nazi Germany.

The successful execution of Operation Neptune involved extensive planning and coordination among various Allied forces, with a massive naval armada providing support for the landing of troops on the beaches of Normandy. This operation not only established a crucial foothold in France but also facilitated the transfer of troops and supplies necessary for sustained military operations in Europe.

Other actions, such as the Battle of Midway, played significant roles in the Pacific theater, while the Battle of the Atlantic was critical for maintaining supply lines. However, these battles are not directly related to the strategic shift in the war in Europe that resulted from the Normandy landings. The Invasion of Italy, while also an important campaign, occurred earlier and had different tactical objectives compared to the Normandy invasions that brought about a significant turning point in the European front. Thus, Operation Neptune stands out as the key naval action associated with the strategic shift during the Normandy landings.
