Your uncle, S/Sgt. Warren A. Gresham, was assigned to Company E, 3rd platoon, 264th regiment, 66th Infantry division. He was one of 41 survivors from his platoon. Only 3 of the 41 survivors from his platoon were hospitalized. He was not hospitalized. No one from 3rd platoon was killed. Stats are from my copy of National archive official army Leopoldville casualty lists prepared on 12/29/1944 & 01/05/1945. Your uncle’s name appears on page 352 of my book, Leopoldville: A Tragedy Too Long Secret, among the names of the 264th regiment Leopoldville survivors.
