The Battle of Song-Jin (Chinese: 松錦之戰) was fought in 1641 and 1642 at Songshan (Chinese: 松山) and Jinzhou (Chinese: 锦州), hence the name "Song-Jin". Hong Chengchou's 100,000 elite troops, sent to break the siege of Jinzhou, were crushed by the Eight banner armies of the Qing Dynasty at Songshan. Hong Chengchou and a small number of the remaining troops were besieged at Songshan and defeated a few months later. The Jinzhou garrison and the general Zu Dashou surrendered to the Qing army shortly after the defeat of Ming armies at Songshan.
