In February 1646, Qing armies seized land west of the Qiantang River from the Lu regime and defeated a ragtag force representing the Longwu Emperor in northeastern Jiangxi. In May, they besieged Ganzhou, the last Ming bastion in Jiangxi. In July, a new Southern Campaign led by Prince Bolo sent Prince of Lu's Zhejiang regime into disarray and proceeded to attack the Longwu regime in Fujian. Hoping to gain rewards from Prince Bolo, Zheng Zhilong betrayed the loyalists by contacting Hong Chengchou and leaving Northern Fujian undefended against a Qing army led by Li Chengdong and Tong Yangjia.
