Jiao Yi

Biography & Historical Record

Jiao Yi was a military officer and advisor who lived during the late Three Kingdoms period. He served as a subordinate commander under Zhuge Dan, the General Who Guards the East for the state of Cao Wei stationed at the strategic stronghold of Shouchun.

In 257 AD, Zhuge Dan instigated the Third Rebellion in Huainan to resist the rising hegemony of the regent Sima Zhao. Jiao Yi, alongside his fellow general Jiang Ban, served in Zhuge Dan’s headquarters as core tactical officers. As Sima Zhao’s massive imperial army surrounded Shouchun with multi-layered siege walls, supplies inside the city dwindled severely. By early 258 AD, news reached the besieged garrison that Eastern Wu reinforcement leaders, including Quan Yisheng, had surrendered to Sima Zhao. Recognizing that the garrison was facing imminent starvation and that Wu’s relief operations had completely collapsed, Jiao Yi and Jiang Ban approached Zhuge Dan with an urgent proposal. They advised Zhuge Dan to assemble all remaining troops for a concentrated, all-out sally to break through a single point of the encirclement while the soldiers still had strength to fight.

Zhuge Dan reacted to their advice with extreme anger, refusing to entertain any thought of retreat or compromise. He shouted at them in a fury, declaring that he would gladly die rather than surrender, and threatened to execute both officers if they ever mentioned retreating again. Realizing that Zhuge Dan was bound for total destruction and fearing for their immediate safety, Jiao Yi and Jiang Ban defected that very night by scaling the city walls under cover of darkness and surrendering to Sima Zhao. Impressed by their foresight and judgment, Sima Zhao welcomed them warmheartedly, granting both officers military ranks and positions within the Cao Wei imperial army.

Role in Romance of the Three Kingdoms

In Luo Guanzhong’s Romance of the Three Kingdoms, Jiao Yi appears in Chapter 112 as a close military advisor to Zhuge Dan during the Third Huainan Rebellion. Besieged inside Shouchun by Sima Zhao’s grand Army, Jiao Yi and Jiang Ban evaluate the desperate situation as provisions run dry. They present a joint petition to Zhuge Dan: ‘Food is exhausted and the troops are starving; Eastern Wu’s relief army has failed us completely. It is better to lead our entire army in a desperate sally to break through one section of the enemy lines.’ Zhuge Dan flies into a rage, bellowing: ‘I would rather die than yield! Suggesting retreat only destroys the army’s morale!’ Threatening them with instant execution, Zhuge Dan dismisses them. Realizing Zhuge Dan’s cause is hopeless, Jiao Yi and Jiang Ban slip over the battlements at night and defect to Sima Zhao, who rewards their judgment with military commissions.
