At 12:30 on 17 December, Kampfgruppe Peiper was near the hamlet of Baugnez when he met the 285th Field Artillery Observation Battalion, U.S. 7th Armored Division. After a battle the Americans surrendered. They were sent to stand in a field. The SS troopers suddenly opened fire on the prisoners. A few survived, and news of the killings of prisoners of war was sent through Allied lines. Following the end of the war, soldiers and officers of Kampfgruppe Peiper, including Joachim Peiper and SS general Sepp Dietrich, were put on trial at the Malmedy massacre trial.
