Gongsun Xiu 公孫修

According to the Biography of Gongsun Yuan, in the 2nd year of Taihe (228) Gongsun Yuan coerced his uncle Gongsun Gong and seized his position. In the 1st year of Jingchu (237), when Guanqiu Jian, Inspector of You Province, and others came bearing an imperial letter under seal to summon him, he raised troops and met them in battle at Liaosui County; after Guanqiu Jian and the others fared badly and withdrew, he made himself King of Yan and established a full array of officials and functionaries.

In the spring of the 2nd year of Jingchu (238) Wei sent the Grand Commandant Sima Yi to attack Gongsun Yuan. Reaching Liaodong in the 6th month, Sima Yi sent the general Hu Zun and others to defeat Bei Yan and the others encamped at Liaosui County, and then hastened straight for Xiangping. The armies again routed Bei Yan and the others at Mount Shou and then dug siege trenches below the city walls. After the summer rains had continued for more than thirty days, when the rain cleared they raised earthen mounds and siege towers and shot into the city, and Gongsun Yuan was driven into desperate straits. His provisions ran out, people ate one another and very many died, and the general Yang Zuo and others surrendered. Records, Wei 8 §47–48

On the night of the bingyin day of the 8th month a great meteor several tens of zhang long fell from northeast of Mount Shou to southeast of the city of Xiangping. On the renwu day, when Gongsun Yuan's host collapsed, Gongsun Yuan and his son Gongsun Xiu led several hundred horsemen, broke through the encirclement and fled to the southeast. The main army pursued them swiftly and beheaded Gongsun Yuan and his son on the very spot where the meteor had fallen. When the city fell, the heads taken from the Chancellor of State downward numbered in the thousands; Gongsun Yuan's head was sent to Luoyang, and Liaodong, Daifang, Lelang and Xuantu were all pacified.

The only place in Chen Shou's main text where Gongsun Xiu's name appears is this one passage, and his courtesy name, offices, age and mother are not recorded. The Annals of Emperor Ming, too, say only that Sima Yi defeated Gongsun Yuan at Xiangping and sent his head to the capital. In the assessment at the end of the volume Chen Shou said that Gongsun Du was cruel and violent without restraint, and that Gongsun Yuan, inheriting his enterprise, added to its viciousness, which served only to overturn his own clan.
