On the right flank of the Pusan Perimeter, in the mountainous region of the ROK II Corps, ROK 6th Division soldiers advanced slowly against the 8th Division. After four days of battle, the 8th Division was destroyed as a combat force, suffering about four thousand casualties. Enemy survivors fled in disarray north toward Yech'on. By September 21, the ROK 6th Division, meeting little opposition, was advancing northward toward Uihung.
