Step-by-step explanation:
The D-Day invasion was a significant event in American history as it marked the beginning of the end for Nazi Germany in World War II. It was a massive amphibious assault launched by American, British, and Canadian forces on June 6, 1944. General Dwight Eisenhower, who later became the 34th President of the United States, led the invasion. The Allied forces used over 5,000 landing and assault craft to transport about 160,000 troops across the English Channel to the beaches of Normandy in France. The successful invasion created a beachhead that allowed for the landing of more troops and heavy equipment, ultimately leading to the liberation of Paris and the eventual defeat of the Germans.
