 In the aftermath of the Battle of Onjong, the Chinese recognized the ROK II Corps as the most vulnerable unit of the Eighth Army. Besides lacking the firepower of their US counterpart, the ROK II Corps also held the most difficult terrain on the UN right flank. At 10 a.m. on November 24, the ROK 7th Infantry Division on the II Corps'left flank attacked north from Tokchon. At the same time, the ROK 8th Infantry Division on the II Corps' right flank advanced north from Yongwon. The stubborn defenses by the PVA 38th and 42nd Corps soon ground the Korean advances to a halt, and the continuous fighting for the next two days failed to create any gains for the Koreans. During the advances, the Chinese defenses managed to create a wedge in the center of the ROK 7th Infantry Division, forcing the division to commit most of its reserves on the front line. Meanwhile, the ROK 6th Infantry Division in the II Corps'rear could only offer its 2nd Infantry Regiment as the corps' reserve due to the earlier losses at Onjong.
