# Wei Xiaokuan

Wei Xiaokuan (韋孝寬) (509 – 17 December 580), formal personal name Wei Shuyu (韋叔裕) (but went by the courtesy name of Xiaokuan), known by the Xianbei name Yuwen Xiaokuan (宇文孝寬) during late Western Wei and Northern Zhou, formally Duke Xiang of Xun (勛襄公), was a general of the Xianbei-led Western Wei and Northern Zhou dynasties of China. He first became a prominent general during Western Wei as he defended the fortress of Yubi (玉壁, in modern Yuncheng, Shanxi) against a vastly larger army commanded by rival Eastern Wei's paramount general Gao Huan, and he eventually contributed greatly to the destruction of Eastern Wei's successor state Northern Qi by Northern Zhou. His final campaign, in 580, saw him siding with the regent Yang Jian against the general Yuchi Jiong in Northern Zhou's civil war, allowing Yang to defeat Yuchi and (after Wei's death) take over the throne as Sui dynasty's Emperor Wen.
More so than other prominent generals at the time, Wei was known for using atypical strategies in both offense and defense, including extensive use of espionage and forgeries to undermine the morale of opposing forces.

## During Northern Wei

Wei Xiaokuan was born in 509, during Western Wei's predecessor Northern Wei (which Western Wei and its rival Eastern Wei were divided from) -- specifically, during the reign of Emperor Xuanwu. His clan was a prominent one in the Sanfu (三輔, greater Chang'an) region, and both his grandfather Wei Zhenxi (韋真憙) and father Wei Xu (韋旭) were commandery governors during Northern Wei.
In Wei Xiaokuan's youth, he was described to be studious and calm. When the general Xiao Baoyin rebelled in 527 and seized the Chang'an region, he was at the capital Luoyang, and he volunteered to serve in the army against Xiao. He served as an officer under Zhangxun Chengye (長孫承業) the Duke of Fengyi and contributed to the army's success, and he was given a post as a teacher at the national university in Luoyang, and then an acting commandery governor. He later served under the prominent official Yang Kan (楊侃), guarding the Tong Pass, when Yang, impressed by him, gave a daughter to him in marriage. Wei became a general during the reign of Emperor Xiaozhuang (528–530) and was created the Baron of Shanbei. During the subsequent reign of Emperor Jiemin (531–532), he served under the official Yuan Zigong (源子恭), the governor of Jing Province (荊州, modern southern Henan) as a commandery governor. It was at this time he became friends with fellow general Dugu Xin, who was also a commandery governor in Jing Province.
In the subsequent reign of Emperor Xiaowu (532–535), Wei was given the task of defending Jing Province, although he was not then governor. Subsequently, when Emperor Xiaowu, seeking to evade the influence of the paramount general Gao Huan, fled west to Chang'an, then controlled by Yuwen Tai, in 534, the empire became divided into Western Wei (with Emperor Xiaowu as emperor) and Eastern Wei (with Emperor Xiaojing of Eastern Wei, whom Gao declared emperor, as emperor). It is unclear when or how, but Wei eventually joined the Western Wei regime in Chang'an, but it is not clear whether that happened before or after Emperor Xiaowu's death (probably by Yuwen's orders) in 535 and replacement by his cousin Emperor Wen of Western Wei.

## During Western Wei

In 538, during a major campaign between Western Wei and Eastern Wei, Wei Xiaokuan accompanied Emperor Wen, and he was made the governor of Hongnong Commandery (弘農, roughly modern Sanmenxia, Henan). He subsequently entered Luoyang (which Western Wei temporarily captured) with Dugu Xin, and for some time tried to defend the city, but eventually they were forced to withdraw from the vicinity of Luoyang. As Wei was then stationed on the borders with Eastern Wei, he became concerned that the Eastern Wei general Niu Daoheng (牛道恆) was capable at drawing the common people of the border region to join Eastern Wei's cause. Wei employed a tactic that he would reuse later—first sending spies to steal samples of Niu's handwriting, and then employing forgers to forge letters purportedly from Niu to Wei offering to defect to Western Wei. He then intentionally allowed spies sent by Niu's superior Duan Chen (段琛) to steal the forgeries, causing Duan to suspect Niu's loyalty and begin to refuse to follow Niu's suggestions. Once Wei was sure of the dissension within the Eastern Wei forces, he made a surprise attack and captured both Duan and Niu, taking the locale for Western Wei.
In 539, Emperor Wen promoted Wei's title from baron to marquess.
In 542, Wei was made the governor of Jin Province (晉州, roughly modern Linfen, Shanxi), and by the recommendation of the prominent general Wang Sizheng (王思政), was given by Yuwen Tai the responsibility of defending the important fort of Yubi (玉壁, in modern Yuncheng, Shanxi), which Wang himself had defended earlier. He managed to pacify the province against raids by the ethnic Xiongnu tribesmen in the area.
In 546, Gao Huan launched a major attack on the Western Wei, starting the Battle of Yubi [zh]. He built earthworks to surround the city, hoping to be able to breach Yubi's defenses on top of the walls, but Wei managed to build on top of the towers on top of the walls, always maintaining a higher vantage point than the earthworks and therefore stopping the Eastern Wei attack. Gao then tried digging tunnels below the walls, but Wei was able to anticipate this and dig tunnels himself to connect with Eastern Wei's tunnels, and then setting fires within the tunnels, burning the Eastern Wei soldiers to death. He further set fires to the Eastern Wei army's battering rams, and for every offensive strategy Gao was able to think of, Wei was able to counter it. Gao had his secretary Zu Ting write a letter to Wei, urging him to surrender, but Wei refused. Gao was unable to capture the fort after 60 days of siege, and he grew angry and ill and was forced to withdraw. For Wei's contributions, he was created the Duke of Jianzhong.
In 553, during the reign of Emperor Wen's son Emperor Fei, Wei was made the governor of the capital region, Yong Province (雍州, roughly modern Xi'an, Shaanxi). In 554, Wei participated in the campaign commanded by Yu Jin (于謹) against the Liang dynasty, which eventually captured its capital Jiangling and its emperor Emperor Yuan. (Western Wei eventually put the Liang emperor to death around the new year 555.) After this campaign, Wei's title was changed to Duke of Rang, and as at the time, Yuwen Tai was choosing prominent Han generals to have their names changed to Xianbei names, Wei's name was changed to Yuwen, probably as a sign of respect and endearment on Yuwen Tai's part. In 556, when Yuwen Tai was carrying out a tour of the northern provinces, he returned Wei to the responsibility of defending Yubi.

## During Emperors Xiaomin and Ming's reigns

Yuwen Tai died later in 556, leaving his son and heir Yuwen Jue under the guardianship of his nephew Yuwen Hu. Around the new year 557, Yuwen Hu forced Emperor Gong of Western Wei to yield the throne to Yuwen Jue, ending Western Wei and founding Northern Zhou, with Yuwen Jue taking the throne as Emperor Xiaomin, but with the alternative title of "Heavenly Prince" (Tian Wang). Wei was made the deputy minister of the interior. After Yuwen Hu removed and killed Emperor Xiaomin later in 557 and replaced him with another son of Yuwen Tai, Yuwen Yu the Duke of Ningdu (as Emperor Ming), Wei took on the additional responsibility as an imperial researcher. (It might have been the case that this was Yuwen Hu's way of removing Wei from a military command without dishonoring him, for Wei's great friend Dugu Xin opposed Yuwen Hu and, in 557, was forced to commit suicide on account of that opposition.) In 560, Yuwen Hu poisoned Emperor Ming to death, and Emperor Ming's brother Yuwen Yong the Duke of Lu became emperor (as Emperor Wu).

## During Emperor Wu's reign

In 561, in recognition of Wei's great victory at Yubi previously, Yubi and the surrounding area was made into Xun Province (勳州 -- "Xun" meaning "achievement"), and Wei was made its governor. During this tenure, Wei was said to be gracious to the people of the province while continuing to effectively employ a network of spies. For example, when his officer Xu Pen (許盆) defected to Northern Qi, Wei sent spies after him, and was quickly able to have him killed.
Around this time, Xun Province continued to be plagued by raids by the ethnic Xiongnu who, while not submitting to either Northern Zhou or Northern Qi, were based within Northern Qi territory and cut off river traffic on the Fen River (汾水, flowing through modern Linfen). In order to cut off the route of their raids, Wei sent his officer Yao Yue (姚岳) to build a fort near the Fen River. Yao initially was fearful that as his troops were building the fort that Northern Qi would launch an attack against him, but Wei warded off Northern Qi attacks by setting up bonfires in the surrounding hills, making Northern Qi forces believe that Yao was being reinforced by a large army, and therefore did not attack Yao, allowing Yao to complete the fort.
In 564, Wei helped negotiate an agreement where Northern Qi returned Yuwen Tai's sister and sister-in-law (Yuwen Hu's mother) to Northern Zhou in exchange for peace. When, late in 564, Yuwen Hu nevertheless was preparing to launch an attack on Northern Qi (in order to placate the northern ally Tujue), Wei sent his secretary Xin Daoxian (辛道憲) to try to dissuade Yuwen Hu, but Yuwen Hu nevertheless launched the attack, which was unsuccessful. In 570, the two states were stalemated while fighting for the control of the city of Yiyang (宜陽, in modern Luoyang). Wei, believing that Yiyang was not worth the effort and instead was apprehensive that Northern Qi would encroach on territory north of the Fen River, sent a proposal to Yuwen Hu to build forts north of the Fen River to guard the territory. Yuwen Hu, however, responded, "While Duke Wei has many descendants, they do not yet number a hundred. Who will be able to guard those forts?" Thereafter, the forts were not built.
Later in 570, Wei's title was promoted to Duke of Xun. That winter, as forewarned by Wei, the Northern Qi general Hulü Guang encroached on Northern Zhou territory north of the Fen River and built forts there, seizing substantial territory. Wei personally met Hulü on the border to try to dissuade him from the campaign, but Hulü did not relent. The armies stalemated after Yuwen Hu sent reinforcements commanded by Emperor Wu's brother Yuwen Xian the Duke of Qi, but territory was already lost.
By 572, however, Hulü was in conflict with the powerful officials Zu Ting and Mu Tipo, both of whom were trusted by the Northern Qi emperor Gao Wei. Wei, hearing this, wanted to create further suspicions in Gao Wei's mind against Hulü, and he decided to try to create a sense that Hulü would rebel. He wrote two songs in couplets, one of which read:
    A hundred sheng [(升, a measurement unit -- and 100 sheng made up one hu (斛))] will fly up to the heavens,
    A bright moon [(明月, mingyue, Hulü's courtesy name)] will shine over Chang'an.
The other read:
    The high [(高, gao)] mountain will collapse on its own,
    The daimyo oak [(槲, hu)] will stand straight on its own.
He sent spies to spread the songs near Northern Qi's capital Yecheng, and the songs soon became popular. Zu, exploiting the situation himself, added two more lines:
    The blind man will bear a great axe,
    The talkative woman will be unable to speak.
Both Zu, who was blind, and Mu's mother Lu Lingxuan (Gao Wei's wet nurse and presumably the "talkative woman") both discussed the songs with Gao Wei, and Gao Wei, his suspicions having been aroused, eventually agreed to have Hulü put to death, greatly weakening the Northern Qi military efforts.
After Hulü's death, Emperor Wu (who had ambushed and killed Yuwen Hu earlier that year and assumed power himself) became particularly ambitious at conquering Northern Qi, and seeing this, Wei submitted three strategies for conquering Northern Qi to Emperor Wu. Also around this time, on account of his old age, Wei repeatedly made offers to resign and retire, but Emperor Wu repeatedly responded with edicts of kind words requesting him to stay.
In 576, when Emperor Wu launched a major attack on Northern Qi, he visited Yubi and praised Wei for his defense of the fort. Wei offered to be the forward commander for the attack, but Emperor Wu declined on reason that he needed Wei to defend Yubi still. However, he sent Wei to assist his brother Yuwen Zhao (宇文招) the Prince of Zhao in a secondary campaign near Yubi. After Emperor Wu conquered Northern Qi in 577, he returned to Yubi and took Wei back to the capital Chang'an with him, promoting Wei to the post of minister of agriculture. Subsequently, however, Emperor Wu made Wei the governor of Yan Province (延州, roughly modern Yan'an, Shaanxi), in charge of the surrounding provinces.

## During Emperors Xuan and Jing's reigns

Emperor Wu died in 578, and his son Yuwen Yun the Crown Prince succeeded him (as Emperor Xuan). In 579, Emperor Xuan passed the throne to his young son Yuwen Chan the Crown Prince (as Emperor Jing), although he held onto power as retired emperor (with the atypical title of "Emperor Tianyuan" (天元皇帝, Tianyuan Huangdi). Later that year, Emperor Xuan made Wei Xiaokuan in charge of Xu Province (徐州, roughly modern Xuzhou, Jiangsu) and the surrounding provinces, and Wei subsequently participated in the campaign against rival Chen dynasty that allowed Northern Zhou to seize the region between the Yangtze River and Huai River from Chen. Wei's contribution was in capturing the important city of Shouyang, and when Emperor Xuan's cousin Yuwen Liang (宇文亮) the Duke of Qi, angry and fearful that Emperor Xuan had recently raped his daughter-in-law Yuchi Chifan, tried to ambush Wei to seize his troops to further act against Emperor Xuan, Wei defeated Yuwen Liang. For these achievements, one of Wei's sons was created the Duke of Hua.
In 580, Emperor Xuan died, and Emperor Xuan's father-in-law Yang Jian the Duke of Sui—the son-in-law of Wei's great friend Dugu Xin—became regent. Yang, suspicious that the general Yuchi Jiong (Yuchi Chifan's grandfather), in charge of Xiang Province (相州, roughly modern Handan, Hebei) and the surrounding regions, tried to replace Yuchi with Wei. Yuchi, however, was suspicious that Yang was intending to usurp the throne, decided to rise against Yang. When Wei approached Xiang Province, he realized this, and he pretended to be ill, and instead tried to flee to Luoyang—on the way, leaving instruction to each post to give feasts to Yuchi's soldiers if they gave chase. Yuchi indeed sent soldiers after Wei, but the soldiers were slowed by the feasts given to them, and were not able to track Wei down. Once Wei reached Luoyang, he carefully guarded the city, and although the ethnically Xianbei soldiers in the city considered rising in support of Yuchi, they ultimately did not do so.
Yang then put Wei in charge of the army against Yuchi. He first defeated Yuchi's general Xue Gongli (薛公禮), who was attacking Huai Province (懷州, roughly modern Zhengzhou, Henan), and then crossed the Yellow River north. He defeated Yuchi's son Yuchi Dun (尉遲惇) near Yuchi's headquarters at Yecheng and then put Yecheng under siege. The city soon fell, and Yuchi Jiong committed suicide. Wei slaughtered the core troops that remained loyal to Yuchi to the end. Wei returned to Chang'an victoriously, and died in December that year.
