The 1st Cavalry Division's Operation Order 9-50, dated 7:00 AM July 22, identified the NKPA 2nd and 3rd Divisions as opposing the division, each with an estimated strength of 8,775 soldiers.
Elements of the NKPA 4th Division were reported to be in reserve behind the other two divisions.
The 1st Cavalry Division's intelligence staff warned that the most likely course of action for these enemy units was to "continue to advance on our positions in the vicinity southeast of Taejŏn with primary effort being to envelop our flanks and thus cut off our units one at a time. Envelopment will be attempted on both flanks with major effort coming from the southeast."
The order directed that civilians "infiltrating through our lines
will be arrested and turned over to CIC [Counter-Intelligence Corps]."
