The Malmedy massacre was a German war crime committed by soldiers of the Waffen-SS on 17 December 1944 at the Baugnez crossroads near the city of Malmedy, Belgium, during the Battle of the Bulge (16 December 1944 – 25 January 1945). Soldiers of Kampfgruppe Peiper summarily killed eighty-four U.S. Army prisoners of war (POWs) who had surrendered after a brief battle. The Waffen-SS soldiers had grouped the U.S. POWs in a farmer's field, where they used machine guns to shoot and kill the grouped POWs; many of the prisoners of war who survived the gunfire of the massacre were executed with a gunshot to the head.
Besides the summary execution of the eighty-four U.S. POWs at the farmer's field, the term "Malmedy massacre" also includes other Waffen-SS massacres of civilians and POWs in Belgian villages and towns in the time after their first massacre of U.S. POWs at Malmedy; these Waffen-SS war crimes were the subjects of the Malmedy massacre trial (May–July 1946), which was a part of the Dachau trials (1945–1947).
