小早川秀秋
Soon after the Chinese ambassadors had safely returned to China in 1597, Hideyoshi sent approximately 200 ships with an estimated 141,100 men under the overall command of Kobayakawa Hideaki. Japan's second force arrived unopposed on the southern coast of Gyeongsang Province in 1596. However, the Japanese found that the Korean army was both better equipped and better prepared to deal with an invasion than several years prior. In addition, upon hearing the news in China, the imperial court in Beijing appointed Yang Hao (楊鎬) 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 historian, estimated that the combined strength of the Chinese army and navy at the height of the second campaign was around 75,000. Korean forces totaled approximately 30,000 with General Gwon Yul's army in Gong Mountain (공산; 公山) in Daegu, General Gwon Eung's (권응) troops in Gyeongju, Gwak Jae-u's soldiers in Changnyeong (창녕), Yi Bok-nam's (이복남) army in Naju, and Yi Si-yun's troops in Chungpungnyeong.
