He [Lt. Col. Gilbert J. Check] took up defensive positions in the evening near the village of Sangyong-ni, south of Poŭn. The battalion assumed responsibility for that sector at 1700 after ROK troops fell back through its position. [12-46]
Colonel Check was unable to obtain from the retreating ROK troops any information on the size of the North Korean force following them or how close it was.
That night he sent 1st Lt. John A. Buckley of A Company with a 30-man patrol northward to locate the enemy. Near Poŭn Buckley saw an enemy column approaching. He quickly disposed his patrol on hills bordering both sides of the road, and, when the column was nearly abreast, opened fire on it with all weapons. This fire apparently caused the enemy advanced unit to believe it had encountered a major position, for it held back until daylight.
