5600, estimated by the U.S.
excerpt from "ebb and flow, US Army November 1950 to July 1951" -
Casualties inflicted on the Chinese by the 23d Regimental Combat Team, counted and estimated, totaled 4,946. Colonel Crombez judged that his task force inflicted over 500 more. The perimeter troops also captured 79 Chinese who at interrogation identified five divisions from the 39th, 40th, and 42d Armies as having taken part in the attacks. The attack force itself, however, appeared to have been no more than six regiments, one each from the 115th, 116th, 119th, and 120th Divisions and two from the 126th Division.
