Gongsun Xu (Late Han)

Overview

公孙续 / Gongsun Xu is Gongsun Zan’s son in the late-Han Yijing endgame. His role is small but structurally important: he is the messenger and outside-relief node linking Gongsun Zan’s trapped fortress, the Black Mountain forces under Zhang Yan, and the failed fire-signal coordination that Yuan Shao exploits.

Current Profile

The bounded sources first show Gongsun Xu being sent from Yijing to seek help from the Black Mountain Army. The final source then places him with 张燕 as a relief force approaches, while Gongsun Zan secretly instructs him to bring 5,000 cavalry to a northern lowland and wait for a fire signal. Yuan Shao’s interception of that letter turns Gongsun Xu’s intended rescue role into the hinge of a deception, and the source closes his arc by noting his later death at the hands of Xiongnu Tuge forces.

Key Characteristics

• Familial relief agent for Gongsun Zan rather than an independently developed political actor.
• Link between Yijing’s trapped center and Black Mountain outside assistance.
• Participant in a failed fire-signal coordination plan that Yuan Shao converts into a trap.
• Disambiguated late-Han figure distinct from the Warring States 公孙续.

Evidence

• Relief mission from Yijing: Hanji 1030 identifies Gongsun Xu as Gongsun Zan’s son and the person sent to seek Black Mountain support.
• Failed outside coordination and death notice: Hanji 1031 places him with Zhang Yan’s relief force, records the intercepted fire-signal instructions, and notes his later killing by Xiongnu Tuge forces.

Qualifications

The sources do not develop Gongsun Xu’s motives, factional base, or command competence in detail. His importance here is relational: he marks how Gongsun Zan’s attempted external rescue depends on communication and trust channels already vulnerable to Yuan Shao.

What Changed

• Hanji 1031 adds Gongsun Xu’s role in the failed 5,000-cavalry fire-signal plan.
• His page now includes the later Xiongnu Tuge death notice.
• The profile now links him more tightly to Yijing’s outside-relief failure rather than only to the earlier request for help.

Relationships

• 公孙瓒 - father and trapped commander whose rescue plan defines Gongsun Xu’s late-Han role.
• 易京 - besieged center from which the relief request and fire-signal plan originate.
• 黑山军 - outside force sought for relief in the Yijing crisis.
• 张燕 - Black Mountain leader associated with the approaching relief force.
• 袁绍 - opponent whose interception of Gongsun Zan’s letter turns Gongsun Xu’s mission into a trap.
• 公孙续 - separate Warring States figure sharing the same romanized name.
