Sun Jian–Liu Biao enmity

Sun Jian–Liu Biao enmity grows from a dispute over the Imperial Seal into a prolonged struggle for Jingzhou, and ends with Sun Jian’s death during the siege of Xiangyang. The account makes their antagonism both personal and territorial: Liu Biao confronts Sun Jian over the Seal, then defends his lands against him, while alliances and the strategic geography of the river crossings repeatedly shape the conflict’s course.

The dispute over the Imperial Seal

After the anti-Dong Zhuo alliance begins to fragment, Sun Jian heads south with his army. Liu Biao, governor of Jingzhou, has received Yuan Shao’s order to stop him, and appoints Kuai Yue and Cai Mao to lead the force sent against him. When the armies meet, Sun Jian asks why his road is blocked; Kuai Yue counters by accusing him of carrying off the Imperial Seal. The accusation turns Sun Jian’s passage home into a confrontation over both political authority and trust.

The two sides choose champions: Sun Jian puts forward Huang Gai, while Liu Biao’s side chooses Cai Mao. Huang Gai lashes Cai Mao with a whip, and Cai Mao flees, prompting Sun Jian’s soldiers to advance. The apparent advantage does not settle the dispute. Liu Biao then arrives with more troops, repeats the charge about the Seal, and asks to search Sun Jian’s baggage. Sun Jian challenges him to fight, but Liu Biao retreats and draws Sun Jian’s men into an ambush, where Kuai Yue and Cai Mao close in from behind. Sun Jian escapes the trap only through a costly fight: three close commanders are killed, and more than half his army is lost before the survivors cross the Yellow River. From then on, Sun Jian and Liu Biao are sworn enemies.

From rivalry to a campaign for Jingzhou

The antagonism is reinforced by the political rivalry surrounding them. Yuan Shu, frustrated when Yuan Shao refuses to provide him with horses and grain, also fails to obtain supplies from Liu Biao. He therefore proposes joining forces with Sun Jian against both Liu Biao and Yuan Shao: Sun Jian is to take Jingzhou, while Yuan Shu moves against Jizhou. Sun Jian accepts, turning the earlier clash over the Seal into an agreed campaign for territory. His eldest son, Sun Ce, asks to accompany him, and joins the war.

Liu Biao prepares to defend his domain, relying on the Yellow River as a barrier. His frontline commander, Huang Zu, positions archers along the river to attack Sun Jian’s approaching boats. For three days Sun Jian’s soldiers remain behind shields while enemy arrows lodge in them. On the fourth day they collect those arrows and fire them back, exploiting the defenders’ exhausted supply. Sun Jian’s troops land and defeat Huang Zu’s men; Huang Zu escapes by leaving his horse and blending in among ordinary soldiers. Sun Jian then captures territory as far as the Han River. Huang Zu withdraws and advises Liu Biao that they cannot hold Sun Jian back.

Xiangyang and Sun Jian’s death

Sun Jian presses his advantage by laying siege to Xiangyang. The narrative sets the impending reversal against two portents: a storm breaks the pole of Sun Jian’s banner, and Liu Biao is told that a star has fallen behind the enemy lines, supposedly foretelling the death of a great general. Liu Biao’s side resolves to seek cooperation from Yuan Shao to eliminate Sun Jian. Lü Gong volunteers to carry the message and is given five hundred soldiers, with instructions to establish an ambush on a nearby hill and signal the besieged city if he succeeds in stopping pursuers.

At night, Lü Gong and his men leave through the eastern gate. Sun Jian hears them and pursues with only thirty horsemen. He rides into the ambush, where a falling stone kills him. He is thirty-seven. His thirty companions are also killed. Lü Gong signals the city, and Liu Biao’s troops come out to attack; the fighting shifts back and forth, Lü Gong is killed, and Huang Zu is captured and taken to Sun Jian’s camp. At daybreak both armies withdraw. The death of Sun Jian changes the immediate stakes: the conflict now concerns the recovery of his body as well as the fate of the campaign.

Negotiation and lasting consequences

Sun Ce learns that his father has been killed and that Liu Biao’s forces have taken the body into Xiangyang. The opposing sides negotiate through the envoy Huan Jie: Sun Ce offers to return Huang Zu in exchange for Sun Jian’s body. Liu Biao agrees, but makes the exchange conditional on the invading troops withdrawing and promising never to attack again. As the envoy is about to return, one of Liu Biao’s advisers argues that the messenger should instead be killed so Liu Biao’s forces can destroy their enemy. The passage presents the proposal as a direct threat to the negotiated settlement, even though Liu Biao has agreed to its terms.

The conflict therefore passes from Sun Jian’s personal rivalry with Liu Biao to a struggle inherited by Sun Ce and bounded by an uneasy bargain. Its causes are layered: suspicion over the Seal, competition for Jingzhou, and the shifting alliances of the warlords. Its outcome is decisive for Sun Jian, who dies in the campaign, but the settlement does not erase the antagonism. Liu Biao’s demand that Sun Jian’s forces withdraw and never return makes the unresolved hostility part of the political landscape that follows.
