Battle of Old Baldy (1953. 3. 23~25)
The Colombian Battalion after being attached to the U.S. 7th Division fought at the Hill 180 battle and took over the guarding duty of the main defense line of Deokeundong in the north of Yeoncheon. And then they fought against the 423rd Regiment of the Chinese Communist 141st Division at the Old Baldy Hill, the outpost of the main defense line. As "A" Company that was dispatched to the Old Baldy Hill suffered heavy casualties by continued bombings by the Chinese Communist, the Battalion decided to replace "A" Company with "B" Company. The Chinese Communist attacked on the night of Mar. 23 when the Battalion was replacing companies.
The Chinese Communist approached to the front of the Battalions position when guarding was less secure while units were replaced. The Colombian Battalion soldiers fought hand to hand with the Chinese Communist that entered their position but had to retreat from the hill as they were outnumbered. The Regiment and Division sent reserve units later for a counterattack, but the loss was mounting and the plan to recapture this hill was abandoned. As a result of this battle, the Old Baldy Hill fell to North Koreas hand after the cease-fire agreement.
After the cease-fire agreement, the Colombian Battalion left in Oct. 1955.
