Before the morning of 1 September had passed, reports coming in to 2nd Division headquarters made it clear that North Koreans had penetrated to the north-south Ch'angnyŏng -Yŏngsan road and cut the division in two; the 38th and 23rd Regiments with the bulk of the division artillery in the north were separated from the division headquarters and the 9th Infantry Regiment in the south. General Keiser decided that this situation made it advisable to control and direct the divided division as two special forces. Accordingly, he placed the division artillery commander, Brig. Gen. Loyal M. Haynes, in command of the northern group. Haynes' command post was seven miles north of Ch'angnyŏng.
