D-Day Definition
D-Day, also known as Operation Overlord, was the codename for the Allied invasion of Normandy, France, on June 6, 1944. It was the largest seaborne invasion in history and a turning point in World War II.
Events Leading Up to D-Day
The planning for D-Day began in 1943, after the Allies had achieved success in the North African Campaign. The invasion was intended to open a second front in Europe and relieve pressure on the Soviet Union, which had been fighting the Germans on the Eastern Front since 1941.
The Allies assembled a massive force of over 150,000 troops, 5,000 ships, and 11,000 aircraft for the invasion. The troops were divided into five assault forces, each assigned to a different beach on the Normandy coast. The beaches were codenamed Utah, Omaha, Gold, Juno, and Sword.
The invasion was originally scheduled for June 5, 1944, but was postponed due to bad weather. On June 6, the weather was still far from ideal, but the Allies decided to proceed with the invasion anyway.
Planning and Logistics
The planning and execution of D-Day, the largest amphibious invasion in history, was a logistical marvel. The operation involved meticulous coordination among Allied forces, extensive planning, and the mobilization of vast resources.
Key individuals and organizations played pivotal roles in the planning process. The Supreme Allied Commander, General Dwight D. Eisenhower, oversaw the overall strategy and coordinated the efforts of the various Allied forces. The British Chiefs of Staff, led by Field Marshal Sir Alan Brooke, developed the initial invasion plan, codenamed Operation Overlord.
The American Joint Chiefs of Staff, headed by Admiral William D. Leahy, provided significant input and support.
