On the first and main road, the 35th Infantry, held a blocking position northwest of Hamch'ang, supported by a platoon of tanks from A Company, A Company, 78th Tank Battalion, and A Battery, 90th Field Artillery Battalion. Colonel Fisher was unable to concentrate his two-battalion regiment here for the defense of on 25 July from P'ohang-dong than it was sent posthaste the next day to reinforce the 27th Infantry Regiment on the next north-south line of communications westward. Thus, in effect, one battalion of U.S. troops stood behind ROK units on the Hamch'ang approach.
On the second road, that leading into Sangju 24th Infantry Regiment assembled two, and later all three, of its battalions. The 2nd Battalion of the 35th Infantry took up a hill position northwest of Hamch'ang and south of Mun'gyŏng on the south side of a stream that flowed past On the north side of the stream a ROK battalion held the front line. Brig. Gen. Vennard Wilson, Assistant Division Commander, insisted that F Company of the battalion should be inserted in the center of the ROK line north of the stream, and this was done over the strong protests of Colonel Fisher and the battalion commander, Lt. Col. John L. Wilkins. Wilson thought the American troops would strengthen the ROK defense; Fisher and Wilkins did not want the untried company to be dependent upon ROK stability in its first engagement. Behind the ROK and F Company positions the ground rose in another hill within small arms range. Heavy rains had swollen the stream behind the ROK's and F Company to a torrent that was rolling large boulders along its channel.
On 22 July the North Koreans attacked. The ROK's withdrew from their positions on either side of F Company without informing that company of their intentions. Soon enemy troops were firing into the back of F Company from the hill behind it. This precipitated an unorganized withdrawal. The swollen stream prevented F Company from crossing to the south side and the sanctuary of the 2nd Battalion positions. Walking wounded crowded along the stream where an effort to get them across failed. Two officers and a noncommissioned officer tied a pair of twisted telephone wires about their bodies and tried to swim to the opposite bank and fasten a line, but each in turn was swept downstream where they floundered ashore a hundred yards away on the same bank from which they had started. Some men drowned in trying to cross the swollen river. The covering fire of a platoon of tanks on the south side held off the enemy and allowed most of the survivors eventually to escape. In this fiasco, F Company lost 6 men killed, 10 wounded, and 21 missing. [12-20]
The next morning  five enemy tanks crossed the river and moved toward Hamch'ang. Artillery fire from a battery of the 90th Field Artillery Battalion knocked out four of the tanks. The fifth turned back across the river, and there an air strike later destroyed it.
