In addition, upon hearing the news in China, the Ming court in Beijing appointed Yang Hao as the supreme commander of an initial mobilization of 55,000 troops from various (and sometimes remote) provinces across China, such as Sichuan, Zhejiang, Huguang, Fujian, and Guangdong. A naval force of 21,000 was included in the effort. Ray Huang, a Chinese-American philosopher and historian, estimated that the combined strength of the Chinese army and navy at the height of the second campaign was around 75,000.
