Zhang Guang

Zhang Guang (259 – October 313), courtesy name Jingwu, was a military general of the Jin dynasty (266–420). He was involved in several significant military campaigns under the Jin, all of which he served with distinction and was eventually assigned to guard the Hanzhong region as the Inspector of Liang province (梁州; not to be confused with the Liang province (涼州) of modern-day Gansu which also existed at the time). Due to the fall of Western Jin, the Hanzhong was isolated from Jin control, and Zhang Guang was forced to govern the region with limited resources and pressure from the Cheng-Han dynasty, Chouchi and rebellious refugee groups. In the end, he was surrounded and died of illness while under siege. Provided by Wikipedia
