By 1939, the world was once again at war. Ten months before the Attack on Pearl Harbor, the 28th Division was ordered into federal service. After America entered World War II, the division trained extensively, both in the homeland and abroad in England and Wales. Landing in France after D-Day, the division fought through Normandy, helped liberate Paris, and ended up bitterly engaged along the "West Wall" of Germany in November 1944. One month later, during the Battle of the Bulge, the division proved instrumental in stalling the last German offensive of the war. The German High Command nicknamed the division "Bloody Bucket" following the fierce battles of the Hurtgen Forest and the Bulge. The unit suffered more than 25,000 casualties of which 2,000 were killed in action. Elsewhere in the war, the division's 111th Regiment was detached to serve in the Pacific; Pennsylvania's 213th Regiment saw action in North Africa and Italy, while other units served across the globe.
