Which historic military operation is associated with June 6, 1944?

The date June 6, 1944, is most famously associated with D-Day, the operation that marked the beginning of the Allied invasion of Normandy during World War II. This pivotal day involved the largest seaborne invasion in history, with Allied forces landing on five beachheads in Normandy, France, to establish a foothold in German-occupied Western Europe.

While "Operation Overlord" is the broader campaign that encompassed the entire Normandy invasion, D-Day specifically refers to the initial landing phase on that particular date. Therefore, saying D-Day emphasizes the exact day that became a turning point in the war, which is critical for understanding the significance of the event.

The other choices, such as Operation Barbarossa, which refers to the German invasion of the Soviet Union beginning in June 1941, and the Battle of the Bulge, which occurred later in late 1944, are not directly connected to June 6. They are important military operations but do not pertain to the events of that specific day.
