In the mountains northeast of Waegwan, the ROK 1st Division continued to suffer from KPA attacks throughout mid-August. KPA pressure against the division never ceased for long. US planners believed the main KPA attack would come from the west, and so it massed its forces to the west of Taegu. It mistakenly believed up to 40,000 KPA troops were near Taegu. This number was above the actual troop numbers for the KPA, which had only 70,000 men along the entire perimeter.
