On the morning of 1 December, 3/7 Marines engaged the PVA 175th Regiment of the 59th Division at Hills 1542 () and 1419 (). The Chinese defenders soon forced the Marines to dig in on the slopes between the road and the peaks when the convoy passed 3/7's position by the afternoon. With Hagaru-ri still not captured, the PVA High Command scrambled the 79th Division to resume attacks on Yudam-ni, while the 89th Division rushed south towards Kot'o-ri. The Chinese struck at night, and the ferocity of the fighting forced the rear covering forces to call in night fighters to suppress the attacks. The fighting lasted well into the morning of 2 December until all the Marines had managed to withdraw from Yudam-ni.
