close-range gunshot wounds to the head — the coup de grâce that ends the life of a fatally-wounded soldier. The head-shot wounds were additional to the gunshot wounds made by the machine guns of the initial gunfire of the massacre. Twenty other soldier corpses showed small-calibre gunshot wounds to the head, without powder-burn residue; 10 corpses had blunt-trauma injuries, likely from having been butt-stroked to death; some corpses showed a single gunshot wound, either to the temple or behind the ear. U.S. Army investigators established that most of the G.I. corpses were in a very small area, which location suggested that the Waffen-SS had assembled and summarily executed their U.S. POWs as quickly as possible after capture. Later, under custody of the U.S. Army, Waffen-SS POWs testified that some American POWs had tried to escape the shootings; other Waffen-SS POWs said that some of the American POWs had recovered their own weapons, and then fired upon Waffen-SS soldiers enroute to Ligneuville. Trial proceedings The trial of US vs. Valentin Bersin et al., Case Number 6-24 (May–July 1946), was one of the Dachau Trials that were held from 1945 to 1947. The tribunal of U.S. Army officers tried 74 Waffen-SS officers and soldiers, most of whom had been members of the 1st SS Division Adolf Hitler Bodyguard. The defendants included SS-Oberst-Gruppenführer Sepp Dietrich, commander of the 6th Panzer Army, SS-Brigadeführer Fritz Krämer, SS-Gruppenführer Hermann Priess, commander of the I SS Panzer Corps, and SS-Standartenführer Joachim Peiper, commander of the 1st SS Panzer Regiment – the principal unit of Kampfgruppe Peiper, who committed the massacre at Malmedy, Belgium. There were originally 75 suspects. However, one of them, 18-year-old Arvid Freimuth, killed himself before the trial started. Another, Marcel Boltz, had his case withdrawn upon the request of the French government since he was a French national. They were going to prosecute Boltz themselves, but dropped the case since they didn't think the evidence was strong enough. Col. Willis M. Everett Jr. (USA) led the defence team, and Col. Burton Ellis (USA) led the prosecution team in the trial of the Waffen-SS war criminals indicted for the massacres of more than 300 US Army POWs "in the vicinity of Malmedy, Honsfeld, Büllingen, Ligneuville, Stoumont, La Gleize, Cheneux, Petit Thier, Trois Ponts, Stavelot, Wanne and Lutrebois" and the massacre of 100 Belgian civilians at Stavelot, during the 16 December 1944—13 January 1945 period at
