What took place on D-Day?

D-Day, which occurred on June 6, 1944, was a pivotal moment in World War II when Allied forces launched a massive invasion of Nazi-occupied France. Known as Operation Overlord, it involved the largest amphibious assault in history, with thousands of troops landing on the beaches of Normandy. This operation marked the beginning of the liberation of Western Europe from Nazi control and was a crucial step towards the eventual defeat of Germany. The landings faced fierce resistance but ultimately established a foothold for Allied forces in France.
