By August 14, large KPA forces were focused entirely on taking P'ohang-dong. However they were unable to hold it because of US air superiority and naval bombardment on the town. The KPA supply chain had completely broken down and more food, ammunition, and supplies were not available. UN forces began their final counteroffensive against the stalled KPA forces on August 15. Intense fighting around P'ohang-dong ensued for several days as each side suffered large numbers of casualties in back-and-forth battles. By August 17, UN forces were able to push KPA troops out of the Kyongju and An'gang-ni areas, putting the supply road to Taegu out of immediate danger. By August 19 the KPA forces had completely withdrawn from the offensive.
