Operation Overlord was the codename of the Allied Normandy invasion on June the 6th 1944 (D-Day). Allied land, naval, and air troops invaded the northern shores of Nazi-held France, and established beachheads (codenamed Utah, Omaha, Gold, Juno and Sword) in five key areas by the next day, opening the area for other Allied troops. The invasion marked the beginning of the end of the Nazi war effort. The invasion, the largest amphibious landing in history, was overseen and executed by General Eisenhower with British field marshalMontgomery in command of Allied ground forces during the invasion. The invasion involved some 800,000 combat troops that had been massed in Britain (mainly in the southern counties) for the operation; over 4,000 ships, under the command of British admiral Sir Bertram Ramsay; and about 5,000 fighters and almost 6,000 bombers that were used to provide air support.
