The Battle of the Ch'ongch'on River, also known as the Battle of the Ch'ongch'on or the Second Phase Campaign Western Sector (Chinese: 第二次战役西线; pinyin: Dì Èr Cì Zhàn Yì Xī Xiàn), was a decisive battle in the Korean War, and it took place from November 25 to December 2 in 1950, along the Ch'ongch'on River Valley in the northwestern part of North Korea. In response to the successful Chinese First Phase Campaign against the United Nations forces, General Douglas MacArthur launched the Home-by-Christmas Offensive to evict the Chinese forces from Korea and to end the war. Anticipating this reaction, the Chinese People's Volunteer Army Commander Peng Dehuai planned a counteroffensive, dubbed the "Second Phase Campaign", against the advancing UN forces.
