Which battle happened first? Operation Overlord or the Battle of the Ch'ongch'on River?
Operation Overlord Operation Overlord was the codename for the Battle of Normandy, the Allied operation that launched the successful invasion of German-occupied Western Europe during World War II. The operation was launched on 6 June 1944 with the Normandy landings (Operation Neptune, commonly known as D-Day). A 1,200-plane airborne assault preceded an amphibious assault involving more than 5,000 vessels. Nearly 160,000 troops crossed the English Channel on 6 June, and more than two million Allied troops were in France by the end of August.
Liberation of Arnhem Operation Anger (sometimes known as Operation Quick Anger), was a military operation to seize the city of Arnhem in April 1945, during the closing stages of the Second World War. It is occasionally referred to as the Second Battle of Arnhem or the Liberation of Arnhem. The operation was part of the Canadian First Army's liberation of the Netherlands and was led by the 49th British Infantry Division, supported by armour of the 5th Canadian Armoured Division, Royal Air Force air strikes and boats of the Royal Navy.
