D-Day occurred on the beaches of Normandy, France during World War 2 while the Nazi/Germany occupied France. The United States military forces, joined with other nations approached the beach from the ocean while the Nazis defended the beach. The Nazi's were eventually overwhelmed after a massive loss of life on both sides, which was the turning point of the war leading to the defeat of the Germans.
