The invasion of Europe, which took place on June 6, 1944, was code-named "Operation Overlord" and was overseen by General Dwight D. Eisenhower, who was the supreme commander of Allied Expeditionary Forces during WWII. On D-Day, more than 156,000 allied troops would cross the English Channel to attack the German army that was dug in at Normandy, France.
"Operation Overlord" was executed with the idea that it would bring a swift end to the war. "Omaha," "Utah," "Gold," "Juno" and "Sword" were the code names for the beaches that received the main amphibious assault by allied forces. The United States, Canada and England landed nearly 133,000 troops on the beaches of Normandy, France, on D-Day, and took 10,300 casualties as a result of the main assault.
