Operation Overlord

The Invasion of Normandy was the invasion and establishment of Allied forces in Normandy, France, during Operation Overlord in World War II. The invasion was the largest amphibious operation in history. The Normandy invasion began with overnight parachute and glider landings, massive air attacks, naval bombardments, early morning amphibious landings on five beaches codenamed Juno, Gold, Omaha, Utah, and Sword and during the evening the remaining elements of the parachute divisions landed. The "D-Day" forces deployed from bases along the south coast of England, the most important of these being Portsmouth.
