The Battle of Normandy, also known as D-Day, took place during World War II from June 6 to August 1944. It began with the Allied invasion of German-occupied France, primarily involving forces from the United States, the United Kingdom, and Canada. The operation aimed to establish a foothold in Europe and ultimately liberate it from Nazi control. The invasion started on June 6, 1944, with a massive amphibious assault on the beaches of Normandy, including famous sites like Omaha Beach and Utah Beach. Following the initial landings, intense fighting continued as Allied troops pushed inland, leading to significant victories and the eventual liberation of Paris in August 1944.
