Yuan Shao–Gongsun Zan alliance and conflict

The relationship between Yuan Shao and Gongsun Zan moves from cooperation to armed conflict and then, under outside mediation, back to an uneasy political alignment. Its defining rupture comes when Yuan Shao turns a proposed joint action against Jizhou into a means of taking control of the province; the ensuing battles at the Pan River make that betrayal visible on the battlefield, while their later reconciliation exposes the fragility of their shared cause.

Alliance Undone by the Seizure of Jizhou

Yuan Shao first proposes that he and Gongsun Zan attack Jizhou together. He then warns Han Fu, the province’s governor, of the danger posed by Gongsun Zan and offers to defend the city alongside him. Some of Han Fu’s advisers recognize the maneuver as an attempt to take power, but most believe Yuan Shao will protect their freedom. Once Yuan Shao arrives with his army, he takes over Jizhou. Two advisers attempt to assassinate him and are killed by his guards; Han Fu receives a grand but ineffectual title and is pushed aside. Only after losing the province does Han Fu understand the deception and flee to Chenliu.

This capture transforms the supposed partners into opponents. Gongsun Zan regards Yuan Shao’s action as treachery and goes on the offensive. At the bridge over the Pan River, their armies face each other from opposite sides. Gongsun Zan calls Yuan Shao a traitor; Yuan Shao answers that Han Fu submitted to him as a superior and challenges Gongsun Zan’s right to intervene. Gongsun Zan counters that Yuan Shao, once regarded as the rightful leader of the uprising, has shown himself to be no better than a beast. Their dispute is thus not merely over possession of a province: both attempt to claim political legitimacy, while Gongsun Zan presents Yuan Shao’s conduct as a betrayal of the cause he once represented.

Battles at the Pan River

Yuan Shao orders an attack, and Gongsun Zan’s forces are driven into retreat. Wen Chou pursues Gongsun Zan, who is exhausted, without a weapon, and thrown from his horse. Zhao Zilong intervenes, holding Wen Chou off long enough for Gongsun Zan’s men to reach him. Zhao had previously served Yuan Shao, but had become disillusioned and was on his way to join Gongsun Zan; their meeting in the midst of the fighting marks his arrival as an ally in action as well as intention.

The battle returns to the bridge, where the commanders’ different military strengths shape the contest. Gongsun Zan relies on cavalry, while Yuan Shao positions a thousand crossbowmen in two wings, with eight hundred additional bowmen and fifteen thousand infantry behind them. Yuan Shao stands at the center of this force. Gongsun Zan plants a large war banner before the bridge and attacks under bombardment, but Yuan Shao’s archers drive his troops back. Yuan Shao’s infantry then cut down the banner and force Gongsun Zan to abandon the bridge. Zhao Zilong again helps prevent disaster, killing the attacking general.

Zhao follows this intervention with a counterattack through Yuan Shao’s troops. Gongsun Zan and his men join him, pressing close to Yuan Shao’s position and nearly breaking through. Yuan Shao rallies his soldiers, reverses the momentum, and forces Gongsun Zan to retreat once more. The fighting consequently brings neither side a decisive victory: individual rescues and reversals alter the immediate danger without ending the contest between the armies.

Xuande’s Intervention and a New Friendship

Just as Yuan Shao believes he is close to victory, Xuande arrives with Zhang Fei, Guan Yu, and their men. Yuan Shao drops his sword in fright and retreats to the safety of his camp. He loses many soldiers in the river and in the counterattack by Gongsun Zan’s forces. The intervention changes the battle’s immediate balance, but does not settle the larger dispute between Yuan Shao and Gongsun Zan.

Afterward, at Gongsun Zan’s camp, Xuande and his sworn brothers meet Zhao Zilong for the first time. Xuande and Zhao quickly become close friends. This personal bond emerges directly from the political and military turmoil: Zhao’s decision to leave Yuan Shao’s service places him alongside Gongsun Zan, and the battle brings him into contact with Xuande’s party.

Stalemate, Mediation, and Political Reversal

The battles at the bridge end in a stand-off that lasts a month. Neither army yields. From Chang’an, Li Ru hears of the deadlock and advises Dong Zhuo to mediate, hoping to bring Yuan Shao and Gongsun Zan back onto Dong Zhuo’s side. The strategy succeeds: the former opponents again align themselves with Dong Zhuo’s political camp.

For Xuande and Zhao Zilong, this reconciliation is not a reassuring settlement. They are profoundly horrified that Yuan Shao and Gongsun Zan have abandoned their earlier cause and returned to cooperation with Dong Zhuo. The episode therefore ends with a political realignment rather than a resolution of the trust broken over Jizhou. Its pattern of alliance, betrayal, battle, and pragmatic reunion demonstrates how shared opposition can be subordinated to immediate political advantage, while the reversal deepens the disillusionment of those who had expected their leaders to remain faithful to their cause.
