Wang Dun 王惇

According to the Biographies of the Three Successor Rulers in Records of Wu 3, when Sun Jun died in the 9th month of the 1st year of Taiping (256), his younger cousin Sun Chen, a Lieutenant General, was made Palace Attendant and General of the Martial Guard in command of all forces inside and outside the capital, and recalled Lü Ju and the others who had gone out to attack Wei. Lü Ju, hearing that Sun Chen had replaced Sun Jun, was furious, and Lü Ju, Wen Qin, Tang Zi and others recommended Teng Yin, General of the Guards, as Chancellor, but Sun Chen would not listen. When Lü Ju led his troops back to attack Sun Chen, on the dingwei day of the 10th month Sun Chen sent Sun Xian, Ding Feng, Shi Kuan and others with ship-borne troops to intercept Lü Ju at Jiangdu, and sent the general Liu Cheng with infantry and cavalry to attack Teng Yin. Teng Yin's troops were defeated and his clan exterminated, and on the xinhai day Lü Ju was captured at Xinzhou. Records, Wu 3 §12–14

In the 11th month, Sun Chen was made General-in-Chief, granted the credentials, and enfeoffed as Marquis of Yongkang. Sun Xian plotted with the general Wang Dun to kill Sun Chen, but the plot was discovered; Sun Chen killed Wang Dun and forced Sun Xian to take his own life. Records, Wu 3 §14

The account of Sun Chen in Records of Wu 19 records this affair differently. Sun Chen was promoted to General-in-Chief, granted the credentials, and enfeoffed as Marquis of Yongning, and relying on his exalted position he was arrogant and often behaved without courtesy. Earlier, Sun Lü, a younger cousin of Sun Jun, had taken part in the plot to kill Zhuge Ke, so Sun Jun treated him generously; he rose to General of the Right and Wunan Commander, was granted the credentials and a canopy, and managed the affairs of the Nine Offices fairly. When Sun Chen treated Sun Lü less generously than Sun Jun had, Sun Lü was angered and plotted with the general Wang Dun to kill Sun Chen. Sun Chen killed Wang Dun, and Sun Lü took poison and died. Records, Wu 19 §83

The two accounts differ on the fellow conspirator, Sun Xian or Sun Lü, and on Sun Chen's fief, Marquis of Yongkang or Marquis of Yongning, and they say that Sun Xian was forced to kill himself and that Sun Lü took poison and died. In both accounts Wang Dun's office is given only as general, and he was put to death by Sun Chen. Records, Wu 3 §14Records, Wu 19 §83

In the 12th month of the 1st year of Yong'an (258), when Sun Chen, who had reluctantly come to the La festival assembly, rose from his seat, Ding Feng and Zhang Bu signaled the attendants with their eyes to bind him. When Sun Chen begged to be banished to Jiao Province, Sun Xiu asked why he had not banished Teng Yin and Lü Ju, and beheaded him. Sun Xiu also issued an edict saying that Zhuge Ke, Teng Yin and Lü Ju had been harmed by the brothers Sun Jun and Sun Chen without guilt, and ordering that they all be reburied and offered sacrifices. Wang Dun's name does not appear in this passage. Records, Wu 19 §99–102

The Biography of the Lord of Wu in Records of Wu 2 records, after the passage on Sun Quan capturing Guan Yu and pacifying Jing Province in the 24th year of Jian'an (219), that Sun Quan sent the Colonel Liang Yu to present tribute to the Han court, had Wang Dun buy horses, and sent Zhu Guang and others back. Chen Shou's main text does not record this Wang Dun's office or what became of him afterward. Records, Wu 2 §26 · 28–29
