The 13th and 15th Regiments of the NKPA 6th Division delivered the attack on Kaesŏng.
Most of the ROK 12th Regiment troops at Kaesŏng and Yŏnan were killed or captured.
Only two companies of the regiment escaped and reported to the division headquarters the next day. Kaesŏng was entirely in enemy hands by 0930.
Darrigo, meanwhile, sped south out of Kaesŏng, reached the Imjin River safely, and crossed over to Munsan-ni.[3-20]

On the regimental left, a ROK patrol from K Company's position on Sobuk-san had the luck to capture the commanding officer of the N.K. 15th Regiment but, unfortunately, he was killed a few minutes later while trying to escape. The patrol removed important documents from his body.
