Zhang Guang

Biography & Historical Record

Zhang Guang (or Zhang Kuang / Zhang Guang in various historical transliterations) was a military officer hailing from Danyang Commandery (Danyang Jun) during the late Eastern Han dynasty. Serving as a trusted subordinate officer under General of the Household Xu Dan, Zhang Guang belonged to the elite Danyang warrior units (Danyang Bing) stationed in Xu Province to defend the capital city of Xiapi.

In 196 AD, an acute internal crisis erupted inside Xiapi while Liu Bei was away fighting Yuan Shu at Xuyi and Huaiyin. Zhang Fei, left in charge of defending Xiapi, engaged in a violent dispute with Tao Bao, a prominent Danyang commander and former subordinate of Tao Qian. Zhang Fei executed Tao Bao, throwing the Danyang troops into panic and rage. Experiencing widespread hostility from Zhang Fei, Xu Dan resolved to betray Liu Bei and invited Lu Bu to seize the city.

Xu Dan selected Zhang Guang for a critical diplomatic mission, dispatching him on a fast horse to secretly reach Lu Bu’s camp outside the city. Zhang Guang delivered Xu Dan’s message verbatim: ‘Zhang Fei has created chaos inside the city and killed General Tao Bao, throwing the governance into complete turmoil and causing hearts to scatter. Currently, our General of the Household Xu Dan commands 1,000 Danyang soldiers garrisoned at the West Ba Gate. Upon hearing that your Lordship is approaching, they jumped for joy as if returned to life! We request that your Lordship march forward immediately; our forces at the West Gate will throw open the gates to welcome you!’

Upon receiving Zhang Guang’s crucial intelligence and promise of insider support, Lu Bu ordered an immediate forced march through the night. Arriving at Xiapi by dawn, Lu Bu’s cavalry found the West Gate opened by Xu Dan and Zhang Guang. Lu Bu’s forces flooded into Xiapi, completely surprising Zhang Fei, who fled in chaos and abandoned Liu Bei’s family and administrative base. Through Zhang Guang’s critical courier mission, Lu Bu seized full control of Xu Province without enduring a prolonged siege. Following this pivotal event, Zhang Guang disappears from historical records.

Role in Romance of the Three Kingdoms

In Luo Guanzhong’s Romance of the Three Kingdoms, Zhang Guang serves as the pivotal messenger dispatched during Lu Bu’s surprise takeover of Xu Province in Chapter 14. Operating as a subordinate officer under Xu Dan among the Danyang garrison at the West Gate of Xiapi, Zhang Guang is sent out to contact Lu Bu after Zhang Fei kills Tao Bao during a drunken rage. Zhang Guang delivers the crucial report detailing the internal turmoil and promising that the Danyang troops will throw open the city gates. His swift courier mission enables Lu Bu to launch an immediate night march, surprise Zhang Fei at dawn, and capture Liu Bei’s capital and family.
