 By nightfall on 18 August, the North Korean 4th Division had been annihilated; huge numbers of deserters had weakened its numbers during the fight, but by that time, Obong-ni and Cloverleaf Hill had been retaken by the U.S. forces. Scattered groups of North Korean soldiers fled back across the Naktong, pursued by American planes and artillery fire. The next day, the remains of 4th Division had withdrawn across the river. In their hasty retreat, they left a large number of artillery pieces and equipment behind which the Americans later pressed into service.
