In the fall of 1944, Allied confidence was high. Flush with success after Normandy, they pushed into Belgium and advanced toward the German frontier. They had no idea that the war was about to take a dramatic turn, one that would result in the U.S. Army's largest and bloodiest conflict of World War II: The Battle of the Bulge. Stunning, newly colorized combat and newsreel footage plus personal memoirs take us to the heart of a battle that would be a catastrophic blow to both sides and leave a muddy graveyard across East Belgium.
