As the Supreme Commander of the Allied Expeditionary Force in Europe, Eisenhower was responsible for planning and executing Operation Overlord, the largest amphibious invasion in history. The successful landing on the beaches of Normandy marked a crucial turning point in World War II, as it enabled the Allies to establish a foothold in Europe and begin the liberation of Nazi-occupied territories. Eisenhower's leadership and strategic foresight were instrumental in the operation's success, solidifying his legacy as a key figure in the war.
