On November 25, 1950, the Chinese 13th Army launched a series of surprise attacks along the Ch’ongch’on River Valley, decimating the U.S. 8th Army’s right flank while allowing Chinese forces to move rapidly into UN rear areas.
With continued fighting from November 26 to December 2, 1950, the Chinese inflicted heavy losses on the retreating UN forces.
After this decisive battle, the 8th Army’s heavy losses forced all UN forces to withdraw south to the 38th parallel.
