On what date did the Battle of Normandy begin?

The Battle of Normandy, more commonly known as D-Day, began on June 6, 1944. This date marks one of the most significant events in World War II, as Allied forces launched a massive invasion of Nazi-occupied France. The operation involved extensive planning and execution, combining naval, air, and ground forces to establish a foothold in continental Europe.

D-Day was pivotal not only for its immediate military impact but also for its role in the eventual liberation of Western Europe from German control. The success of the landings at various beaches along the Normandy coast set the stage for subsequent operations that would lead to the downfall of Nazi Germany.

The other dates provided in the options do not correspond to the initial invasion. July 4, 1944, falls well after D-Day; August 15, 1944, is when the Allied invasion of southern France, known as Operation Dragoon, took place; and September 1, 1944, has no relevance to the events of the Normandy invasion. Thus, June 6, 1944, is consistent with historical accounts of this landmark military operation.
