Normandy landings
The landing started on the so-called D-Day. It was by the Allies of World War II: the United States, the United Kingdom, Canada, Australia, and other countries. The whole event was codenamed "Operation Overlord" and was intended to open the Western Front in the war. It was the largest seaborne invasion in history. After the landing, the Allied forces failed to take any of the towns and places that they had planned to take. However, they controlled the beaches, and in the following days, they moved inland.
