On June 6, 1944, the largest air, land and sea invasion in military history took place on the Normandy coast of France. The Battle of Normandy, often referred to as D-Day and codenamed "Operation Overlord," has been described by historians as a major turning point for the Allied forces in World War II. The 150,000 Allied troops, made up of American, British and Canadian forces, landed on the beaches of Nazi-occupied France and were then able to push inland to Western Europe. The bravery displayed by these troops has been depicted in many books and films, including "Saving Private Ryan"...
