By August 7, the KPA 13th Division had crossed the Naktong River at Naktong-ni, northwest of Taegu. ROK troops attacked the 13th Division immediately after it completed its crossing, forcing the KPA troops to scatter into the mountains. The division reassembled to the east and launched a concerted night attack, broke the ROK defenses, and began an advance that carried it twenty miles (32 km) southeast of Naktong-ni on the main road to Taegu. Within a week, the KPA 1st and 13th divisions were converging on the Tabu-dong area, about north of Taegu.
