captives. In 1658, Shi was made Deputy Commander of Tongan. He continued to participate in campaigns against the Zhengs. Shi passed on information such as Zheng internal conflict between Chenggong and his son onto Beijing. The Qing established a naval force in Fujian in 1662 and appointed Shi Lang as the commander. Huang and Shi advocated for more aggressive action against the Zhengs besides just a coastal evacuation policy. On 15 May 1663, Shi attacked the Zheng fleet and succeeded in capturing 24 Zheng officers, 5 ships, and killing over 200 enemies. Shi planned to attack Xiamen on 19 September, but the Qing court decided to postpone the assault until Dutch naval reinforcements arrived. From 18 to 20 November, the Dutch fought sea battles against the Zheng 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 due to the departure of the Dutch fleet. However, after the defection of Zheng commander Zhou Quanbin, Zheng Jing decided to pull out from the remaining mainland stronghold in the spring of 1664. Shi was not content with just the defeat of Zheng forces on the mainland. He proposed to the Qing court an invasion of Penghu and Taiwan. In November 1664, Shi's fleet set sail but was turned back by a storm. He tried again in May 1665 but there was too little wind to move the ships and then a few days later the winds reversed direction and forced him to return. Another failed attempt was made in June when they were met with a violent storm, sinking a few small ships, and damaging the masts of several other ships. Shi's flagship was blown to the coast of Guangdong on 30 June. In 1666, the Qing called off the expedition. Preparations Shi Lang was instructed to arrange the necessary ships, escorts, and provisions for a peace mission to Taiwan, but he did not believe Zheng Jing would accept the Qing's terms. He delivered a memorial to Beijing on 7 January 1668 and warned that if the Zhengs built up their strength, they would pose a serious danger. Shi detailed his plans to invade Taiwan with just 20,000 men and 170 battle ships. He required 10 new battle ships and 20 troop transports to be constructed. He argued that by
