Sun En 孫恩

Sun En appears in the account of Sun Chen in the Biographies of Zhuge Ke, Teng Yin, the Two Suns and Puyang Xing (Records of Wu 19) and in the Biographies of the Three Successor Rulers (Records of Wu 3). His elder brother Sun Chen, courtesy name Zitong, shared a grandfather with Sun Jun, and their father Sun Zhuo was Commandant Who Pacifies the People. When Sun Jun died, Sun Chen, as Palace Attendant and General of the Martial Guard, took command of all the forces inside and outside the capital and ran the government of the court, and was later promoted to General-in-Chief and enfeoffed as Marquis of Yongning.

When Zhuge Dan, General-in-Chief of Wei, rebelled holding Shouchun, Wu sent a relief army. Sun Chen encamped at Huoli and had Zhu Yi attack Wei, but when Zhu Yi was defeated again and again and would not obey the order to fight to the death with thirty thousand men, Sun Chen beheaded him at Huoli and sent his younger brother Sun En to the rescue. Just then Zhuge Dan was defeated, and Sun Chen led his army back. Chen Shou wrote that because Sun Chen had failed to rescue Zhuge Dan, had lost his troops and had himself killed a famous general, there was no one who did not resent him. Records, Wu 19 §84–86

When Sun Liang first took personal charge of government and questioned him more and more, Sun Chen became very afraid. Returning to Jianye, he pleaded illness and did not attend court, placed his younger brother Sun Ju, General Who Awes the Distant, in the Canglong Gate on guard duty, and stationed his younger brothers Sun En, General of the Martial Guard, Sun Gan, Lieutenant General, and Sun Kai (孫闓), Colonel of the Changshui, separately in the various camps, seeking to dominate the court and secure his own position.

Sun Liang plotted with Princess Sun Luban, the Minister of Ceremonies Quan Shang and the general Liu Cheng to kill Sun Chen, but Sun Liang's consort, the daughter of Sun Chen's elder female cousin, revealed the plot to Sun Chen. On the wuwu day of the 9th month of the 3rd year of Taiping (258), Sun Chen attacked Quan Shang by night, sent his younger brother Sun En to attack and kill Liu Cheng outside the Canglong Gate, and then surrounded the palace; gathering the high ministers at the palace gate, he deposed Sun Liang and made him Prince of Kuaiji.

Sun Chen sent the Director of the Imperial Clan Sun Kai (孫楷) and the Gentleman of the Secretariat Dong Chao to receive Sun Xiu, Prince of Langya. In the 10th month, when Sun Xiu reached Busai Pavilion, Sun En, General of the Martial Guard, acting in the affairs of the Chancellor, led the hundred officials to welcome him at Yongchang Pavilion with the imperial carriage and full ceremonial equipage; he had a temporary palace built, made a military tent the side hall and set up the imperial seat there. On the jimao day, Sun Xiu, seeing the side hall, stopped and had Sun Kai go ahead to meet Sun En, and only after Sun Kai returned did he advance in the hand-drawn carriage. Later Sun Xiu raised by one rank all the generals and officials who had received and attended him at Yongchang Pavilion. Records, Wu 3 §21–22 · 28

On the renwu day of the 10th month, in winter, of the 1st year of Yong'an (258), Sun Xiu issued an edict making Sun Chen Chancellor and Governor of Jing Province, and making Sun En, General of the Martial Guard, Imperial Counsellor, General of the Guards and Commander of the Central Army, enfeoffed as a county marquis. Sun Chen's biography records that Sun En and Sun Ju both became county marquises and Sun Gan and Sun Kai (孫闓) village marquises, so that five men of Sun Chen's one family became lords and all commanded the palace troops; their power overshadowed the sovereign, something never before seen among the ministers of the Wu court.

When Sun Chen brought beef and wine to Sun Xiu and Sun Xiu would not accept them, Sun Chen went to the General of the Left Zhang Bu and spoke resentfully, and Zhang Bu reported this to Sun Xiu. Fearing an uprising, Sun Xiu gave him reward after reward, and also gave Sun En the additional post of Palace Attendant so that he would share the oversight of documents with Sun Chen. The Biographies of the Three Successor Rulers record that an edict of the wuxu day of the 11th month said that since the General-in-Chief's duties were numerous, Sun En, General of the Guards and Imperial Counsellor, was given the additional post of Palace Attendant to share the oversight of affairs with the General-in-Chief.

When Sun Xiu asked him in secret, Zhang Bu plotted with Ding Feng to kill Sun Chen at a banquet. At the La festival banquet on the wuchen day of the 12th month of the 1st year of Yong'an (early 259 CE), Ding Feng and Zhang Bu signaled to the attendants to bind Sun Chen, and Sun Xiu beheaded him. Holding up Sun Chen's head, they proclaimed that all who had plotted with him were pardoned, and five thousand men laid down their arms; Sun Kai (孫闓), who boarded a boat intending to go north and surrender, was pursued and killed, and Sun Chen's three sets of kin were exterminated. Chen Shou's main text does not say separately what became of Sun En at this time. Records, Wu 19 §98–101Records, Wu 3 §28
