After a short rest, the breakout began on 6 December, with the 7th Marines as the vanguard of the retreating column, while the 5th Marines covered the rear. At the same time, the much-delayed PVA 26th Corps arrived at Hagaru-ri with its 76th and 77th Divisions to relieve the 58th and 60th Divisions. As the 7th Marines pushed aside the PVA 76th Division south of Hagaru-ri, the 5th Marines took over the Hagaru-ri perimeter and recaptured the East Hill from the 76th Division. In a last effort to stop the breakout, the customary Chinese night attack was launched, with the 76th and 77th Division striking the Hagaru-ri perimeter from all directions. The Marines repulsed the attacks, inflicting heavy casualties.
