The landing started on the so-called D-Day. It was by the Allies of World War II: the U.S.A., the U.K., Canada, Australia and other forces. The whole event was codenamed "Operation Overlord" and intended to open a new Western Front of the war. It was the largest seaborne invasion in history. After landing, the Allied forces failed to take any of the towns and places they had planned to take. However, they were able to control the beaches, and in the following days they moved inland.
