On August 10, the Eighth Army organized "Task Force P'ohang" — the ROK 17th, 25th, and 26th Regiments as well as the ROK 1st Anti-Guerrilla Battalion, Marine Battalion and a battery from the US 18th Field Artillery Regiment. This task force was given the mission to clear out KPA forces in the mountainous region. At the same time, Eighth Army formed "Task Force Bradley", consisting of elements of the 8th Infantry Regiment, 2nd Infantry Division. "Task Force Bradley" was tasked with defending P'ohang-dong. What followed was a complicated series of fights throughout the region around P'ohang-dong and An'gang-ni as ROK forces, aided by US air forces, engaged groups of KPA in the area. The KPA 12th Division was operating in the valley west of P'ohang-dong and was able to push back "Task Force P'ohang" and the ROK Capital Division, which was along the line to the east. At the same time, the KPA 766th Infantry Regiment and elements of the KPA 5th Division fought "Task Force Bradley" at and south of P'ohang-dong. US naval fire drove the KPA troops from the town, but it became a bitterly contested no man's land as fighting moved to the surrounding hills.
