Answer:
D-Day was the Allied invasion of Normandy, France on June 6, 1944 during World War II. It was the largest seaborne invasion in history, involving over 150,000 Allied troops from Britain, Canada, and the United States. The Allied forces were led by General Dwight D. Eisenhower, with the goal of liberating Europe from Nazi control. The invasion was launched from England, with troops landing on the beaches of Normandy. The heavy casualties of the invasion were not in vain, as the Allies were ultimately successful in liberating France, and eventually Europe, from Nazi rule.
