Yelü Xiuge

Biography

Family Background and Early Years

Yelü Xiuge came from the Liao imperial clan. His grandfather Yelü Shilu, Prince of Sui, was the younger brother of the ancestor Saliadi and an uncle of Liao founder Yelü Abaoji. His father Yelü Wansi held a high tribal military office. The History of Liao says that Xiuge showed from youth the qualities of a great minister. Around 965 he followed Xiao Gan against rebellious Wugu and Shiwei groups, and around 968 military merit brought promotion to Tiyin, an important office dealing with imperial-clan affairs.

Fame at the Gaoliang River

In 979 Emperor Taizong of Song personally led a northern expedition seeking the Sixteen Prefectures of Yan and Yun. After a series of Liao reverses, the Southern Capital, present-day Beijing, was besieged. Emperor Jingzong ordered Yelü Xiuge to replace Yelü Xidi and bring the Five Courts troops to its relief.

At the Gaoliang River, outside present-day Beijing, Xiuge and Southern Administration King Yelü Xiezhen struck the Song army from two wings. The Song army was routed and pursued for more than thirty li, with heavy losses. Xiuge himself suffered three wounds. Emperor Taizong fled south; because Xiuge was too badly wounded to ride, he pursued in a light carriage as far as Zhuozhou but did not catch him. The battle lifted the siege of the Southern Capital, severely damaged the Song army, and established Xiuge's reputation.

Mancheng and Waqiao Pass

In winter 979 Jingzong sent Han Kuangsi and others south. At Mancheng, Song troops offered a false surrender. Xiuge observed that their formation remained orderly and aggressive and warned Han that it was a trap, but Han ignored him. The Song then attacked suddenly and the Liao army collapsed. Because Xiuge had held his own force in readiness on higher ground, he restored order and covered the retreat. Jingzong thereafter entrusted him with southern garrisons and made him Northern Administration King.

In 980 Jingzong personally campaigned. At Waqiao Pass Xiuge killed Song commander Zhang Shi and pursued the enemy toward Mozhou. Before battle Jingzong saw that Xiuge's horse armor was conspicuously yellow and gave him dark armor and a white horse so that he would not be singled out. Xiuge led elite cavalry across the river, routed the Song army, and captured commanders after his arrows were exhausted. Jingzong rewarded him with an imperial horse and gold vessel, praising his courage, and on the return march appointed him Yuyue, the highest honorific office of the Liao.

Command of the Southern Frontier and the Qigou Pass Victory

When Shengzong came to the throne in 983 under Xiao Chuo's regency, Xiuge was placed in overall command of the southern military frontier with discretion to act as circumstances required. He redistributed garrison burdens, established a rotation-and-rest system, encouraged agriculture and sericulture, and strengthened military preparedness. The sources describe the frontier as becoming well governed.

During the Northern Song Yongxi Northern Expedition of 986, the Song attacked in three columns, with Cao Bin and Mi Xin commanding the powerful eastern army. Before Liao reinforcements arrived, Xiuge avoided a premature pitched battle. At night he sent light cavalry to kill isolated soldiers; by day he displayed elite troops to keep the enemy continually on guard; he placed ambushes in woods and grasslands and cut supply routes. Cao Bin's army, short of supplies, fell back, then advanced again. Xiuge continued harassment, forcing the Song soldiers to move in square formations and dig entrenchments while suffering severe thirst.

When Xiao Chuo arrived with the main Liao army, the Song withdrew in rain. Reinforced, Xiuge pursued, surrounded troops defending themselves around supply carts, and drove Cao Bin and Mi Xin into flight. He then attacked tens of thousands of Song troops at the Sha River; panic caused large numbers to drown or be trampled. Liao forces killed many thousands and captured large quantities of armor. After the victory Xiuge piled Song corpses into a victory mound and was created Prince of Song. He proposed exploiting Song weakness and advancing the frontier to the Yellow River, but the court did not adopt the plan.

Junziguan and Later Years

In winter 986 Xiao Chuo again campaigned south and Xiuge served as vanguard, first defeating Song troops at Wangdu. He then met Liu Tingrang's army, killed Li Jingyuan, drove Liu to flee with only a few riders, and captured He Lingtu and Yang Chongjin at Junziguan. He was summoned to the inner palace and rewarded with wine. Liao troops then continued south, taking Qizhou and attacking Shenzhou, Shucheng, Wen'an, and other places.

In 988 Xiuge again led troops south and attacked Zhuozhou, defeated Li Xing, and took Mancheng, Qizhou, Xinle, and other places. In 989 he suffered a rare reverse at the Xu River. Song commander Yin Jilun, whose force Xiuge had underestimated and passed without precaution, launched a night attack between the Tang and Xu rivers. Xiuge was struck in the arm while eating and had to flee on a fast horse, and his army broke in disorder. Thereafter he guarded the frontier more cautiously and avoided deep penetration into Song territory. He later also fought Liu Tingrang north of the Sha River, inflicting heavy losses and taking supplies. Xiuge died of illness on December 22, 998.

Major Activities

Military Contributions

Yelü Xiuge's career covered most of the major early Liao-Song wars. He was central to Liao victories at the Gaoliang River, Waqiao Pass, Qigou Pass, and Junziguan. His ability was not limited to frontal combat. At Qigou Pass he avoided battle while outnumbered, used night attacks, deception, ambushes, and supply interdiction to exhaust the Song army, and only struck decisively after reinforcements arrived.

Frontier Administration

From 983 Xiuge had long-term responsibility for the southern border. He equalized garrison obligations and introduced regular rotation so soldiers could rest, encouraged agricultural production, and repaired military preparations and defenses. The sources credit these measures with restoring both local stability and military strength.

Reputation

Xiuge's name inspired fear in Song territory. Sources say that south of Baigou parents quieted crying children by saying, “The Yuyue is coming,” a story reflecting his military reputation across the border.

Relations with Contemporaries

Xiuge enjoyed the confidence of Emperor Jingzong, Xiao Chuo, and Emperor Shengzong. He fought beside Yelü Xiezhen at the Gaoliang River. At Mancheng he served under Han Kuangsi, whose refusal to accept Xiuge's warning resulted in defeat and highlighted Xiuge's judgment.

Historical Assessment

Liao / Contemporary

The History of Liao praised Xiuge for broad strategic vision, seemingly prophetic judgment of enemies, long combat experience, and restraint from indiscriminate killing. Emperor Jingzong praised his courage after Waqiao Pass, and Xiao Chuo's decision to give him discretionary authority over the southern frontier demonstrates the trust placed in him.

Song and Yuan Periods

The History of Song records Xiuge's reverse against Yin Jilun, while also showing the strength of the Liao force Yin surprised. Song anecdotal writings preserved the story of his name being used to stop children crying. The Yuan compilers of the History of Liao gave him a full biography and treated him as a leading Liao commander.

Ming and Qing Periods

Wang Qi discussed Xiuge as one of the key figures enabling Liao to resist Song expansion. Li E examined details of his exhaustion tactics at Qigou Pass, and Zhao Yi called Xiuge and Yelü Xiezhen “bulwarks of the Liao.”

Modern and Contemporary

Chen Shu regarded Xiuge as one of the most important military commanders of the early and middle Liao. Tao Jinsheng analyzed his Qigou Pass tactics as an example of fighting successfully while initially weaker. Modern scholarship generally treats him as one of the outstanding Liao commanders of the Liao-Song confrontation.
