Shi Lang led the Qing conquest of Zheng Taiwan. He was originally a military leader working under Zheng Zhilong, the father of Zheng Chenggong. He had a falling out with Chenggong. After escaping imprisonment by Chenggong, Shi Lang defected to the Qing dynasty and participated in a successful assault on a Zheng stronghold. In 1658, Shi was made Deputy Commander of Tongan and continued to participate in campaigns against Zheng forces. Shi relayed information about Zheng internal conflict between Chenggong and his son to Beijing. The Qing established a naval force in Fujian in 1662 and appointed Shi Lang as the commander. Shi advocated for more aggressive action against the Zhengs. On 15 May 1663, Shi attacked the Zheng fleet and succeeded in killing and capturing Zheng forces. From 18 to 20 November, the Dutch fought sea battles against Zheng forces while Shi took Xiamen. In 1664, Shi assembled a fleet of 240 ships, and in conjunction with 16,500 troops, chased remaining Zheng forces south. They failed to dislodge the last Zheng stronghold. After the defection of Zheng commander Zhou Quanbin, Zheng Jing pulled out from the remaining mainland stronghold in the spring of 1664.
