South of Waegwan, two more KPA divisions stood ready to cross the Naktong River in a coordinated attack with the divisions to the north. The experienced KPA 3rd Division was concentrated in the vicinity of Songju, while the untested KPA 10th Division was concentrated in the Koryong area. These two divisions crossed in the US 1st Cavalry Division's line. The KPA 3rd Division's 7th Regiment started crossing the Naktong on August 9. Despite being spotted and taking fire, the bulk of it reached the east bank safely and moved inland into the hills. The 5th Cavalry Regiment and its supporting artillery, now fully alerted, spotted the other two regiments and forced them back to the west bank. Only a small number of KPA reached the east side where either they were captured, or hid until recrossing the river the following night.
