The D-Day invasion began on June 6, 1944 and was the largest seaborne invasion in history. It was an Allied invasion, primarily as a way to gain a foothold in mainland Europe during World War II. The Allies, which included forces from the United States, Great Britain, Canada, and Free France, sailed across the English Channel and landed on the beaches of Normandy. On the beaches, the Allies fought against the Nazi forces in what has become known as the Battle of Normandy, the Battle of D-Day, or the Battle of the Beaches. After fierce fighting, the Allies were eventually successful in liberating France from Nazi occupation. The D-Day invasion was a turning point in World War II and marks one of the most pivotal moments in modern history.
