 Early in the morning on August 15, G Company men on Hill 303 spotted 50 North Korean infantry supported by two T-34 tanks moving south along the river road at the base of the hill. They also spotted another column moving to their rear which quickly engaged F Company with small arms fire. In order to escape the enemy encirclement, F Company withdrew south, but G Company did not. By 08: 30, North Koreans had completely surrounded it and a supporting platoon of H Company mortarmen on Hill 303. A relief column, composed of B Company, 5th Cavalry, and a platoon of US tanks tried to reach G Company, but was unable to penetrate the North Korean force that was surrounding Hill 303.
