The Battle of the Kumsong River, also known as the Jincheng Campaign (Chinese: 金城战役; pinyin: Jīn Chéng Zhàn Yì), was one of the last battles of the Korean War as well as the last large-scale battle of the war. In July 1953, after the Republic of Korea (ROK) refused to participate in peace negotiations between the Communist and UN forces, the Chinese forces launched an attack on the Kumsong River Salient at the south of the town of Kumsong, scoring a victory over the UNC forces.
