The Battle of Penghu was a naval battle fought in 1683 between the Qing dynasty and the Kingdom of Tungning. The Qing admiral Shi Lang led a fleet to attack the Tungning forces in Penghu. Each side possessed more than 200 warships. The Tungning admiral Liu Guoxuan was outmaneuvered by Shi Lang, whose forces outnumbered him three to one. Liu surrendered when his flagship ran out of ammunition and fled to Taiwan. The loss of Penghu resulted in the surrender of Zheng Keshuang, the last king of Tungning, to the Qing dynasty.
