Hong Chengchou positioned his troops on Mt. Rufeng which stands between Songshan and Jinzhou. When the battle first started the Qing forces did badly. Hong Taiji therefore decided to remain on the defensive, conducting only small scale attacks on the Ming army's front line. When the enemy became exhausted, he would then release a full-scale attack to achieve victory. The impatient Chongzhen emperor ordered his marshal to be more aggressive, playing into Hong Taiji's plans.
