8. The Allied Invasion of Normandy (D-Day, 1944)
On June 6, 1944, Operation Overlord commenced with the largest amphibious invasion in history, known as D-Day. Allied forces, including American, British, and Canadian troops, landed on five Normandy beaches—Utah, Omaha, Gold, Juno, and Sword—to establish a foothold in Nazi-occupied France. This operation was pivotal in liberating Western Europe from Nazi control. In comparison, earlier amphibious operations, such as the Gallipoli Campaign during World War I, were smaller in scale and less successful, highlighting the strategic significance of D-Day.
