耿秉 / Geng Bing (Eastern Han)

Overview

耿秉 / Geng Bing is the Eastern Han general whose current bounded profile links the first Northern Xiongnu policy debate to Dou Xian’s later campaign. Hanji 759 presents him advising Empress Dowager Dou to support the Southern Xiongnu request against Northern Xiongnu; Hanji 760 and Hanji 761 then place him as Dou’s deputy and Yanran participant.

Current Profile

Hanji 759 introduces Geng Bing in a decision-advice role. When the Southern Xiongnu chanyu asks Han to join an attack on Northern Xiongnu and specifically asks for Geng and Deng Hong, the dowager consults Geng. He supports the proposal, arguing that the moment fits a use-barbarian-against-barbarian strategy and asking to serve personally.

Hanji 760 shows Geng’s advice becoming part of Dou Xian’s punishment-conversion path. After Dou Xian is implicated in the Liu Chang murder case and asks to redeem a capital offense by attacking Northern Xiongnu, he is appointed chariot-and-cavalry general with Geng as deputy.

Hanji 761 then makes Geng part of the victorious campaign memory. Dou and Geng depart by the Jilu route, other forces move separately, and the campaign produces the Jiluoshan victory, mass submission, and the Yanran commemoration. Geng’s current profile is therefore not an independent command biography; it is the military-support line that helps transform an earlier policy opportunity into Dou’s campaign.

Qualifications

This page is bounded to Hanji 759-761 and does not reconstruct Geng Bing’s full military career. The sources use him mainly as an experienced frontier voice and campaign deputy, while Dou Xian remains the politically dominant actor in the branch.

What Changed

• Created Geng Bing as a bounded Eastern Han entity from Hanji 759-761.
• Linked his pro-expedition advice in Hanji 759 to the later deputy and Yanran roles already present in Hanji 760-761.
