The Battle of the Ch'ongch'on River (Chinese: 清川江战役; pinyin: Qīngchuānjiāng Zhànyì), also known as the Battle of the Ch'ongch'on, was a battle in the Korean War that took place from November 25 to December 2, 1950, along the Ch'ongch'on River Valley in the northwestern part of North Korea. In response to the successful Chinese First Phase Offensive against the United Nations (UN) forces, General Douglas MacArthur launched the Home-by-Christmas Offensive to expel the Chinese forces from Korea and to end the war. Anticipating this reaction, the Chinese People's Volunteer Army (PVA) Commander Peng Dehuai planned a counteroffensive, dubbed the "Second Phase Campaign", against the advancing UN forces. Hoping to repeat the success of the earlier First Phase Campaign, the PVA 13th Army first launched a series of surprise attacks along the Ch'ongch'on River Valley on the night of November 25, 1950, at the western half of the Second Phase Campaign (Chinese: 第二次战役西线; pinyin: Dì'èrcì Zhànyì Xīxiàn), effectively destroying the Eighth United States Army's right flank, while allowing PVA forces to move rapidly into UN rear areas.
