Sun Ce’s conquest of Jiangdong transforms a campaign undertaken with borrowed troops into the foundation of an independent regional power. Seeking to avenge his father and secure his family, he obtains an army from Yuan Shu by leaving the Imperial Seal as a pledge; in the ensuing campaign, military victories, Taishi Ci’s change of allegiance, and the army’s restraint toward local people help turn an expedition into a durable political foothold.

Background and the Borrowed Army

Sun Ce’s court had become known as a center of learning and statesmanship, but his position under Yuan Shu remained uneasy. Yuan Shu praised him at a celebration, yet Sun Ce felt patronized and privately doubted himself when comparing his standing with that of his murdered father. Yuan Shu’s commander Zhu Zhi and adviser Lü Fan urged him to assert his independence, and the two helped devise a plan.

The next day, Sun Ce asked Yuan Shu for three thousand infantry and five hundred cavalry. He presented two reasons for needing them: his father’s murder remained unavenged, and his mother and family were in the power of Liu Yao. In return, Sun Ce left the Imperial Seal with Yuan Shu as a token of trust. Yuan Shu wanted the seal, but affected indifference as he accepted it and supplied the troops. The exchange provided Sun Ce with an army while also making clear that his expedition rested on a temporary bargain, not settled allegiance.

As Sun Ce set out, his childhood friend Zhou Yu joined him with an army of his own. Zhou Yu also recommended that they seek the help of two brothers reputed to interpret auspicious and ill-fated signs. The campaign thus began with both practical military support and an appeal to guidance from signs, while Sun Ce’s immediate aims remained grounded in family security and revenge.

The Contest with Liu Yao and Taishi Ci

Liu Yao, a member of the imperial family, learned that news of his mistreatment of Sun Ce’s family had reached Sun Ce and that an army was approaching. He prepared to resist and sent troops to defend the crossing at Niuzhu. They were defeated with heavy losses, allowing Sun Ce to advance against Liu Yao’s main force.

Before the armies met in full, Sun Ce dreamed that the founder of the Later Han summoned him to a temple dedicated to his memory. Told that the temple lay south, near Liu Yao’s camp, Sun Ce’s advisers cautioned him against going. He insisted that he wanted to pray for success and trusted that the gods would protect him, then rode there with only twelve guards. His visit exposed him to the enemy, but Liu Yao mistook the apparent vulnerability for a trap and would not send out his full force.

Taishi Ci, eager to fight, rode out despite Liu Yao’s objections, accompanied by only one other commander. He and Sun Ce fought for fifty rounds without either gaining the advantage. Taishi Ci drew Sun Ce away from his twelve guards by pretending to flee; their contest resumed and continued after both men fell from their horses, until soldiers from both armies arrived and separated them. The scene establishes their rivalry as a personal contest as well as a military one, but it does not settle the campaign.

The feud shaped the fighting between the two forces as subterfuge and battle continued across the countryside. Taishi Ci was eventually captured and brought before Sun Ce, who greeted him as a hero rather than treating him merely as a defeated opponent. When Sun Ce asked whether Taishi Ci would have killed him if their first fight had ended in capture, Taishi Ci admitted that he did not know. Sun Ce laughed and invited him to dine. Moved by this treatment, Taishi Ci offered to bring over Liu Yao’s disheartened and divided troops if Sun Ce would trust him.

Sun Ce accepted the offer. Taishi Ci recruited thousands of Liu Yao’s soldiers to join Sun Ce, converting a former adversary into a trusted intermediary and turning the divisions within Liu Yao’s force into a source of new strength. The episode’s movement from duel to dinner to recruitment makes personal recognition a practical instrument of conquest: the defeated warrior’s knowledge and influence help enlarge the victor’s army.

Conquest and the Conduct of the Army

After crossing the river and moving south, Sun Ce’s army initially caused panic and disorder. That response changed as local people saw that the soldiers did not steal or harm ordinary residents. People began bringing food and drink to the camp. The narrative therefore presents the army’s conduct not as incidental to conquest but as one of the conditions through which a frightening armed force could gain local support.

Further south, Sun Ce encountered conspirators, thugs, rebels, and bandits who sought to exploit his advance and take territory for themselves. His response was swift and severe; with Taishi Ci now assisting him, he won a succession of battles and captured cities including Jiaxing, Wucheng, and Wujun. The campaign expanded through both the defeat of competing armed groups and the accumulation of territory, while the army’s restraint toward ordinary people offered a contrast to the disorder the expedition had first produced.

The campaign also reaches beyond Sun Ce’s own front. At Xuancheng, his brother Sun Quan and companion Zhou Tai were guarding the area when mountain robbers launched a sudden nighttime attack. Zhou Tai, caught unprepared, fought bravely and rescued Sun Quan, but was brought to Sun Ce’s camp gravely wounded. Sun Ce searched for a capable doctor and was directed to Hua Tuo, who treated Zhou Tai with herbal remedies and medicines; Zhou Tai recovered within a month. Enraged by the attack, Sun Ce then led a swift campaign that eradicated the mountain robbers. The episode connects the security of Sun Ce’s family and companions to the wider work of securing his emerging territory.

Political Independence and Significance

After these victories, Sun Ce strengthened his hold on key places, reported his success to the Han court, made contact with Cao Cao, and demanded that Yuan Shu return the Imperial Seal. These actions mark a change in the campaign’s political meaning. The seal had enabled Sun Ce to obtain troops from Yuan Shu; after building his own position, Sun Ce sought its return rather than remaining defined by the loan that had launched his advance.

The conquest belongs to the larger fragmentation of the Han world, in which Liu Bei, Cao Cao, and Sun Quan emerge as leaders who carve out kingdoms from the failing empire. Sun Ce’s Jiangdong campaign shows the early construction of the power later associated with the Sun family: military force opens the way, but the episode also stresses recruitment, control of key locations, and conduct toward the population. Its closing actions—reporting to the court, dealing with Cao Cao, and demanding back the pledge—present Sun Ce not simply as a successful commander but as a leader moving toward political autonomy.
