Final answer:
D-Day's main goal was to establish a foothold in Normandy to begin liberating Western Europe from Nazi control, spearheaded by General Dwight D. Eisenhower and resulting in the largest amphibious assault in history.
Step-by-step explanation:
The main goal of the D-Day invasion, which took place on June 6, 1944, was to establish a strong foothold in Normandy, France, and begin the liberation of Western Europe from Nazi occupation. Under the code name Operation Overlord, the invasion involved thousands of American, British, and Canadian forces landing along a fifty-mile stretch of heavily fortified beaches. With General Dwight D. Eisenhower as the Supreme Allied Commander, the landing was the largest amphibious assault in history and would eventually lead to the liberation of Paris and mark a turning point in World War II.
