Du Yu 杜預 was a Field Marshal who served the Jin Dynasty during the end of the Three Kingdoms era. Du Yu was the most important commander under Zhong Hui. When Zhong Hui died and Wei was abolished, Du Yu served Sima Yan of Jin. When Sima Yan sent Du Yu to attack Sun Hao as guardian of the south, Du Yu did not waste time slaughtering the Wu forces. The Wu forces could not defend from the Jin forces and in a matter of time, Sun Hao finally surrendered to Jin, which was the end of Wu Dynasty and the conclusion of the Three Kingdoms.
