Quan Yi (Wu)

Biography & Historical Record

Quan Yi was an aristocratic military general, senior division commander, and hereditary nobleman of the Eastern Wu state who later defected to Cao Wei during the late Three Kingdoms period. Hailing from Qiantang in Wu Commandery, Quan Yi was the son of the legendary Grand Commander Quan Cong and the imperial princess Sun Luban (Princess Quan, eldest daughter of Sun Quan and Lady Bu). Inheriting his father’s illustrious noble title as Marquis of Linxiang, Quan Yi occupied a preeminent position among the Jiangdong aristocracy, possessing command over substantial family garrisons and imperial elite divisions. Documented in Chen Shou’s official dynastic history Records of the Three Kingdoms (Sanguozhi – Book of Wu, Biography of Quan Cong; Book of Wei, Biography of Zhuge Dan) and Sima Guang’s Zizhi Tongjian, Quan Yi is best known historically for his leadership during the Eastern Wu expedition to support Zhuge Dan’s rebellion at Shouchun in 257 and his subsequent defection to Sima Zhao.

In the fifth month of 257, Grand General Zhuge Dan launched a massive rebellion in Huainan against the regent Sima Zhao, dispatching hostages and emissaries to negotiate an alliance with Eastern Wu. Seeing an unprecedented opportunity to destabilize the northern rival, the despotic regent Sun Chen mobilized a massive expeditionary army exceeding seventy thousand troops. Sun Chen appointed Quan Yi, alongside his kinsman Quan Duan, Quan Jing, Quan Yi (Quan Hui), and the northern defector Wen Qin, to command the vanguard force. Displaying decisive tactical speed, Quan Yi and Wen Qin breached Sima Zhao’s outer encirclement lines and successfully marched into the fortified citadel of Shouchun before the Wei armies could fully seal the siege perimeter.

However, the siege dragged into winter, resulting in severe food shortages and deteriorating relations inside Shouchun between Zhuge Dan and Wen Qin. Meanwhile, in the Wu capital of Jianye, internal disputes within the Quan clan flared: several young kinsmen, including Quan Hui and Quan Yi, defected to Sima Zhao due to familial friction. Recognizing an opportunity to break the defense of Shouchun from within, Sima Zhao and his brilliant strategist Zhong Hui forged clandestine letters in the names of the defected Quan kinsmen. The forged messages claimed that regent Sun Chen was furious at the lack of military progress at Shouchun and intended to purge and execute the entire remaining Quan household in Jianye, advising Quan Yi to surrender immediately to avoid clan destruction.

Upon receiving the secret letters in the twelfth month of 257, Quan Yi and Quan Duan were gripped by profound terror, well aware of Sun Chen’s notorious cruelty and arbitrary purges of senior ministers in Jianye. Believing that their home families had already perished or faced execution, Quan Yi and Quan Duan led several thousand elite troops out of the eastern gates of Shouchun and surrendered unconditionally to Sima Zhao. Welcoming their submission with supreme political calculation, Sima Zhao treated Quan Yi with immense lavishness, confirming his hereditary noble title as Marquis of Linxiang in Wei and appointing him Champion General (Guanyun Jiangjun). The defection of Quan Yi and his primary strike detachment shattered the morale of Shouchun’s defenders, paving the way for the total collapse and storming of the city in early 258. Quan Yi spent his remaining years residing peacefully as a high-ranking noble in the Central Plains.

Role in Romance of the Three Kingdoms

In Chapters 111 and 112 of Luo Guanzhong’s classic 14th-century historical novel Romance of the Three Kingdoms, Quan Yi is featured as Eastern Wu’s principal vanguard commander whose relief of Shouchun and fateful defection under Zhong Hui’s psychological stratagem seal the doom of Zhuge Dan’s grand rebellion.

In Chapter 111, following Zhuge Dan’s armed insurrection against Sima Zhao in Shouchun, Eastern Wu agrees to send a grand army to divide the northern empire. Regent Sun Chen dispatches General Quan Yi and his nephew Quan Duan to lead thirty thousand elite troops to reinforce Zhuge Dan. Arriving at Shouchun just as Sima Zhao begins entrenching his siege trenches, Quan Yi coordinates a ferocious assault alongside Wen Qin, smashing through the Wei perimeter and linking up with Zhuge Dan inside the city.

In Chapter 112, the siege reaches a desperate stalemate as food supplies dwindle and winter frosts set in. Outside the walls, Wei strategist Zhong Hui observes that Quan Yi’s family in Jianye has had falling-outs with Sun Chen. Zhong Hui devises a brilliant alienation plot: he directs the captured Wu officer Quan Yi (Quan Hui) to draft forged letters bearing official family seals, which are secretly shot into Shouchun on crossbow bolts. The letters warn Quan Yi: ‘Sun Chen is enraged that our army has failed to break the siege and is slaughtering our clan in Jianye! If you do not submit to the Great General Sima Zhao, our entire lineage will be wiped out!’

Reading the letters, Quan Yi is consumed by despair and dread. Conferring secretly with Quan Duan, Quan Yi exclaims: ‘Sun Chen is a vicious tyrant who executes generals without hesitation. Our families are doomed if we stay!’ That very night, Quan Yi and Quan Duan lead several thousand armored soldiers out of the southern gates, presenting their weapons and flags to Sima Zhao’s camp. Sima Zhao rejoices, grants Quan Yi high military rank, and parades the surrendered Wu commanders before the walls of Shouchun. Witnessing Quan Yi’s defection, Zhuge Dan’s garrison falls into complete panic and despair, leading directly to the final storming of the fortress and Zhuge Dan’s death. Luo Guanzhong commemorates the episode as a masterclass in psychological warfare, demonstrating how internal fear and distrust dismantled the strongest military bastion of the late Three Kingdoms.
