Prior to the invasion, Hong Taiji sent Abatai, Jirgalang, and Ajige to secure the coastal approaches to Korea, so that Ming could not send reinforcements. On 9 December 1636, Hong Taiji led Manchu, Mongol, and Han Banners against Joseon. Chinese support was particularly evident in the army's artillery and naval contingents. The defected Ming mutineer Kong Youde, ennobled as the Qing's Prince Gongshun, joined the attacks on Ganghwa and Ka ("Pidao"). The defectors Geng Zhongming and Shang Kexi also played prominent roles in the Korean invasion.
