Defection of Fu Shiren and Mi Fang

The Defection of Fu Shiren and Mi Fang was a pivotal turn in the struggle for Jingzhou: the surrender of Gong’an and Nanjun gave Sun Quan’s forces control of two cities while Guan Yu was already facing pressure from the advancing Wu army. The episode turns on more than military imbalance. Yu Fan’s appeal to the officials’ grievances, Fu Shiren’s break with his former allegiance, and the arrival of an urgent demand from Guan Yu combine to make the defense of Nanjun collapse from within.

The cities and the opening

After Lü Meng captured Jiangling, Sun Quan arrived with his army. With the Jingzhou region in Wu’s hands, his forces turned to securing Gong’an and Nanjun, controlled respectively by Fu Shiren and Mi Fang. Holding those cities mattered to the campaign: their allegiance would determine whether Wu could consolidate its gains beyond Jiangling.

Yu Fan identified the personal conflict that might open the gates. Neither governor was pleased with Guan Yu, who had reprimanded and punished them. Yu Fan reasoned that an offer to escape Guan Yu’s authority might persuade them to change sides. The plan treated resentment as a military opportunity, making a fractured chain of loyalty as consequential as the movements of armies.

Fu Shiren opens Gong’an

The proposal reached Fu Shiren by an arrow shot over the walls of Gong’an. Remembering his earlier disgrace at Guan Yu’s hands, he decided his future lay elsewhere. He opened the gates and went with Yu Fan to deliver the city keys to Sun Quan.

Sun Quan initially considered appointing Fu Shiren governor of Gong’an. Others cautioned that, if Guan Yu returned to attack, Fu Shiren might betray his new master in turn. Rather than entrust him with the city, they sent him to Nanjun to approach Mi Fang, his old friend and fellow target of Guan Yu’s displeasure. The transfer made Fu Shiren both a defector and the instrument of a second surrender.

Mi Fang’s decision

In Nanjun, Mi Fang had already heard that Jiangling had fallen. Fu Shiren arrived in person and urged him to surrender to Wu, saying the odds against him had left no choice. Mi Fang resisted: he said he could not betray the king of Hanzhong and reminded Fu Shiren that he and his brother had served their lord for many years.

Fu Shiren answered by returning to the grievance that had shaped his own decision. Guan Yu had treated them harshly, he argued, and would neither forget nor forgive if he prevailed. Mi Fang’s stated loyalty and Fu Shiren’s warning set service to their lord against fear of the commander who represented that lord’s authority. The episode presents the conflict as a choice under pressure, not as a settled lack of allegiance on Mi Fang’s part.

The demand and the surrender

The debate changed when a messenger arrived from Guan Yu demanding that the two cities provide large quantities of rice for the army. Fu Shiren killed the messenger, an act that astonished Mi Fang. Fu Shiren declared that Guan Yu meant to have them killed, interpreting the demand as a trap rather than an ordinary military requisition.

News then arrived that Lü Meng was advancing on Nanjun. The approaching force finally persuaded Mi Fang to surrender the city, and Lü Meng received the news with delight. The change of sides thus followed a sequence of converging pressures: resentment of Guan Yu, Fu Shiren’s intervention, the grain demand, and the immediate threat of Wu’s advance.

Military consequences

The capture of Gong’an and Nanjun completed Wu’s seizure of key positions in Jingzhou and weakened Guan Yu’s ability to hold the region. The defection was followed by the account of Xu Huang fighting Guan Yu and Guan Yu retreating. In the wider campaign, the surrendered cities were therefore not merely local losses: they formed part of the pressure that forced Guan Yu away from his position as Wu consolidated its control.

The episode also draws a contrast between formal loyalty and the practical conditions that sustain it. Mi Fang invokes years of service and his duty to his lord, yet gives way when Fu Shiren’s warning is reinforced by a demand he takes to be threatening and by Lü Meng’s advance. Wu’s victory comes through force, but also through knowledge of an adversary’s internal resentments—and through turning those resentments into an opening for surrender.
