North of the US 9th Infantry and the battles in the Naktong Bulge and around Yongsan, the US 23rd Infantry Regiment after daylight of September 1 was in a very precarious position.
Its 1st Battalion had been driven from the river positions and isolated 3 miles (4.8 km) westward.
Approximately 400 KPA now overran the regimental command post, compelling Freeman to withdraw it about 600 yards (550 m).
There, 5 miles (8.0 km) northwest of Changnyong, the 23rd Infantry Headquarters and Headquarters Company, miscellaneous regimental units, and regimental staff officers checked the KPA in a 3-hour fight.

The KPA advanced to Changnyong itself during the afternoon of September 2, and ROK National Police withdrew from the town.
KPA were in Changnyong that evening.
With his communications broken southward to the 2nd Infantry Division headquarters and the 9th Infantry, Haynes during the day decided to send a tank patrol down the Yongsan road in an effort to re-establish communication.
C Company, 72nd Tank Battalion, led its tanks southward.
They had to fight their way down the road through several roadblocks.
Of the three tanks that started, only the lead tank got through to Yongsan.
There, it delivered an overlay of Task Force Haynes' positions to Bradley.

Still farther northward in the zone of the US 38th Infantry the KPA were also active.
After the KPA breakthrough during the night of August 31, Keiser had ordered the 2nd Battalion, 38th Infantry, to move south and help the 23rd Infantry establish a defensive position west of Changnyong.
In attempting to do this, the battalion found KPA troops already on the ridges along the road.
They had penetrated to Hill 284 overlooking the 38th Infantry command post.
This hill and Hill 209 dominated the rear areas of the regiment.
At 06:00 September 3, 300 KPA launched an attack from Hill 284 against the 38th Regiment command post.
The regimental commander organized a defensive perimeter and requested a bombing strike which was denied him because the target and his defense perimeter were too close to each other, but the USAF did deliver rocket and strafing strikes.

This fight continued until September 5.
On that day F Company captured Hill 284 killing 150 KPA.
From the crest he and his men watched as many more KPA ran into a village below them.
Directed artillery fire destroyed the village.
Among the abandoned KPA materiel on the hill, Schauer's men found twenty-five American BARs and submachine guns, a large American radio, thirty boxes of unopened US fragmentation and concussion grenades and some rations.
