Here, the Filipino Battalion recaptured the Christmas Hill by supporting this Company's counterattack and made a preparation for a Chinese Communist counterattack. While the Battalion was defending the outpost it built at the point 1.3km from the hill's right side, it was attacked by the Chinese Communist Army on the night of Jul. 18. It defeated them and continued to defend this battle line until the cease-fire agreement was signed. As a result of this battle, the Christmas Hill (south near Hill 1090) was included in the south side of the military demarcation line.
After the cease-fire agreement, the Filipino Battalion left in May 1955.
