In 279, with the general Ma Long (馬隆) having finally put down Tufa's rebellion, Emperor Wu concentrated his efforts on Eastern Wu, and commissioned a six-pronged attack led by his uncle Sima Zhou, Wang Hun (王渾), Wang Rong, Hu Fen (胡奮), Du Yu, and Wang Jun, with the largest forces under Wang Hun and Wang Jun. Each of the Jin forces advanced quickly and captured the border cities that they were targeting, with Wang Jun's fleet heading east down the Yangtze and clearing the river of Eastern Wu fleets. The Eastern Wu chancellor Zhang Ti (張悌) made a last-ditch attempt to defeat Wang Hun's force, but was defeated and killed. Wang Hun, Wang Jun, and Sima Zhou each headed for Jianye, and Sun Hao was forced to surrender in spring 280. Emperor Wǔ made Sun Hao the Marquess of Guiming. The integration of former Eastern Wu territory into Jin appeared to have been a relatively smooth process.
