The "Malmédy Massacre" was a war crime committed on 17 December 1944 by Peiper combat troops at Baugnez crossroads. 82 Americans were taken prisoner and shot there. Each of the black rectangular stones on the wall of the War Memorial bears the name of a victim.
That same SS unit perpetrated further mass shootings over the next few days, including those at Honsfeld and Büllingen. The cases were brought before the military court at Dachau in 1946.
