ROK troops attacked toward An'gang-ni to the east, forcing the KPA's 12th Division into a full retreat. Threatened with encirclement, the KPA's 5th Division and 766th Regiment were ordered into full retreat on August 17. By this time, the 766th had been reduced to 1,500 men, half its original strength. Exhausted and out of supplies, the 766th Regiment moved to Pihak-san, a mountain north of Kigye, to join the shattered KPA's 12th Division. The 12th Division was reduced to 1,500 men in the fighting, and 2,000 army replacements and South Korean conscripts were brought to replenish the division. The 766th Regiment was also ordered to merge its remaining troops into the depleted KPA's 12th Division. Upon the completion of the merger with the 12th Division on August 19, 1950, the 766th Regiment ceased to exist. It had trained for close to 14 months prior to the war but fought for less than two.
