 The PVA 38th Corps landed the first blow against the ROK II Corps at 5 p.m. on November 25 . Aided by total surprise , the PVA 113th Division of the 38th Corps first shattered the ROK 7th Infantry Division 's Reconnaissance Company on the division 's right flank , creating a 0 @.@ 5 mi ( 800 m ) gap between the ROK 7th and 8th Infantry Division . Simultaneously , the PVA 114th Division of the 38th Corps attacked the center @-@ right of the ROK 7th Infantry Division , pushing the ROK 5th and 8th Infantry Regiment back in the process . When the ROK 7th Infantry Division 's center and right were in complete chaos , the PVA 112th and the 113th Division of the 38th Corps slipped past the UN lines and advanced towards Tokchon . With only one battalion in reserve to check the Chinese divisions , the Tokchon garrison and the ROK 7th Infantry Division headquarters were soon surrounded and attacked by the two Chinese divisions at 4 a.m. on November 26 . Under heavy pressures from the PVA 114th Division , the ROK 5th and 8th Infantry Regiment tried to fall back to Tokchon , but the Chinese ambushes in the rear scattered the unsuspecting Koreans . On the afternoon of November 26 , Tokchon was captured by the Chinese , and the ROK 3rd Infantry Regiment on the ROK 7th Infantry Division 's left flank drifted westward and joined the US 2nd Infantry Division .
