The Ill-Fated Northern Expedition
Following the conquest of Northern Han, the Song army was jubilant, and Emperor Taizong, intoxicated by victory, proposed an immediate campaign against the Liao Dynasty. Since Shi Jingtang of the Later Jin had ceded the strategic Sixteen Prefectures of Yan and Yun to the Liao, recovering these lost territories had become an obsession for the Central Plains. While Emperors Shizong of Zhou and Taizu of Song had failed in this endeavor, Taizong believed that the momentum from defeating Liao reinforcements at Taiyuan offered a perfect opportunity. However, many generals cautioned against it, arguing that the troops were exhausted from recent fierce battles. General Huyan Zan explicitly warned, “Overturning the Liao pancake is not easy; Your Majesty should not take such risks.” Ignoring all advice, Taizong ordered the army to march north directly from Taiyuan.
Initially, the Song advance into Liao territory was smooth, with Liao forces retreating continuously. Taizong quickly besieged Youzhou (modern Beijing). Despite fierce assaults, the Liao defenders held firm. The tide turned when Liao reinforcements arrived under the command of the formidable general Yelu Xiuge. At the Battle of Gaoliang River north of the city, the Liao cavalry proved superior, charging wildly and gaining the upper hand. Caught between the city’s sortie and the external assault, the isolated Song army suffered heavy casualties. Emperor Taizong himself was struck by two arrows and fled in a donkey cart, marking a disastrous defeat for the Song.
The Guardian of Yanmen Gate
Emboldened by the Song’s weakness, the Liao launched frequent raids. However, at Yanmen Pass (north of modern Daixian, Shanxi), they met the formidable force of Yang Ye. In one notable engagement, as Liao troops approached the pass, Yang Ye led an elite detachment to circle behind the enemy, coordinating with the garrison to launch a pincer attack. The Liao army was routed, fleeing in disarray. From then on, the sight of the “Yang” banner sent Liao troops retreating in fear. Yang Ye’s reputation soared, earning him the nickname “Invincible.”
Jealous generals whispered to Emperor Taizong that Yang Ye, a former Northern Han defector, could not be trusted and should be removed. Instead, Taizong demonstrated remarkable trust: he sealed these slanderous reports and sent them directly to Yang Ye. Deeply moved by this imperial confidence, Yang Ye dedicated himself even more fervently to defending the frontier.
The Ambitious Campaign of 986
Years later, Emperor Jingzong of Liao died, leaving his young son, Emperor Shengzong (Yelu Longxu), under the regency of the formidable Empress Dowager Xiao. Perceiving an opportunity to exploit a ruler who was merely a child and his mother, Emperor Taizong resolved to launch a second northern expedition to avenge the Gaoliang River defeat and reclaim the lost prefectures. In the spring of 986, he mobilized elite forces for a three-pronged attack, commanding from the capital while his generals executed his detailed battle plans.
The Eastern Route, led by Cao Bin as the main force, aimed to capture Zhuozhou and then Youzhou. The Central Route, under Tian Chongjin, advanced from Xiongzhou to support the main effort. The Western Route, commanded by Pan Mei with Yang Ye as his deputy, was to exit Yanmen Pass and strike towards Yunzhou. Taizong handed them meticulously drawn maps and strategies, confident of victory.
The Collapse of the Eastern Front
Reality, however, diverged sharply from the emperor’s projections. Cao Bin’s force initially succeeded in taking Zhuozhou. Empress Dowager Xiao responded swiftly, dispatching Yelu Xiuge to intercept. A master strategist, Yelu Xiuge targeted the Song supply lines, forcing Cao Bin to retreat. When the Song attempted to reoccupy Zhuozhou after resupplying, Empress Dowager Xiao personally took command at the front, besieging the city. Yelu Xiuge again severed the supply lines, trapping the Song army inside. Forced to break out, Cao Bin’s troops fled south, only to be pursued relentlessly by the Liao cavalry. At the Juma River, the exhausted Song forces were decimated in a decisive battle; legend says the corpses choked the river flow. This route ended in catastrophe.
Tian Chongjin’s central force had achieved some success, capturing Feihu and Lingqiu, but upon hearing of Cao Bin’s disaster, Emperor Taizong panicked and ordered a general retreat. Tian Chongjin was forced to withdraw, surrendering his gains back to the Liao.
The Betrayal at Chenjiagu
The Western Route under Pan Mei had been the most successful, capturing Shuozhou, Yingzhou, Huanzhou, and Yunzhou. As they prepared to link up with the main force, news of Cao Bin’s defeat arrived, prompting an order to retreat. Pan Mei began withdrawing, escorting thousands of civilians who wished to flee to Song territory. Suddenly, Liao forces under Yelu Xiezhen counterattacked, closing in rapidly.
Pan Mei convened a war council with Yang Ye and the military supervisors (Jianjun) Wang Shen and Liu Wenyu. Yang Ye argued pragmatically: “The enemy is too strong. If we engage directly, we will surely lose. I propose sending a diversionary force to Yingzhou to draw the enemy away, allowing us to retreat safely with the troops and civilians through Yanmen Pass.”
Wang Shen sneered, and Liu Wenyu shook his head. Though mere supervisors, Wang and Liu held immense power as the emperor’s confidants, often overshadowing the commanding general. Wang Shen loudly objected: “Facing a great enemy, how can we retreat? Yang General’s plan is cowardly! We must engage in a decisive battle to show the might of the Great Song!” When Yang Ye insisted that a direct confrontation meant certain defeat, Wang Shen stood up and pointed accusingly: “Are you not called ‘Invincible’? Why do you hesitate? Do you intend to defect again?” Liu Wenyu nodded in agreement.
Stung by the accusation of disloyalty, Yang Ye flushed with anger. “I do not fear death, nor will I surrender!” he declared. “I only wish to avoid sacrificing our soldiers in vain. Very well, I will go. Even if I die, my loyalty is clear to Heaven!” Pan Mei remained silent throughout the exchange.
Before departing, Yang Ye returned to Pan Mei and Wang Shen, tears in his eyes. “I was a surrendered general, yet the Emperor trusted and employed me. I will repay this with my life. My death matters little, but the lives of these soldiers must be saved. I will draw the enemy to Chenjiagu. General Pan, please ambush the valley mouth there. When I lure the enemy in, strike from the flank. Can you do this?” Pan Mei agreed, “Rest assured, General Yang, it shall be done.” Wang Shen said nothing.
The Hero’s Last Stand
Yang Ye marched out, driven by a mix of duty and wounded pride. Halfway, he encountered Yelu Xiezhen’s forces. Charging at the forefront, Yang Ye pushed the enemy back to Langya Village, where they fell into a Liao ambush. After a bloody struggle, Yang Ye broke out and retreated to Chenjiagu, expecting Pan Mei’s ambush forces. Instead, the valley was empty. Pan Mei and Wang Shen, having waited for a while and assuming Yang Ye had won, had already departed. Even when news reached them that Yang Ye was at Chenjiagu, they did not return.
Realizing he was abandoned and outnumbered, Yang Ye knew death was inevitable. He told his men, “I am old; my death is of no consequence. You all have parents, wives, and children. Flee and save yourselves!” The soldiers wept, refusing to leave: “We will die alongside you, Old General!” Moved to tears, Yang Ye led his remaining men in a final charge. They killed numerous enemies, but Yang Ye sustained multiple injuries. When his horse fell, he was captured. His son Yang Yanyu, the veteran general Wang Gui, and many soldiers perished on the battlefield.
Martyrdom and Legacy
Yang Ye’s capture shocked the Liao court. Desperate to recruit such a formidable commander, they offered him high office. Yang Ye, having sworn never to surrender, refused food and drink. After three days of fasting, he died at the age of sixty.
News of his martyrdom sent shockwaves through the Song court. Public outrage demanded punishment for Wang Shen, Liu Wenyu, and Pan Mei. Emperor Taizong, upon investigating the truth, was furious. Wang Shen and Liu Wenyu were stripped of their titles and exiled, while Pan Mei was demoted three ranks.
Yang Ye’s legacy lived on through his descendants. His son Yang Yanzhao and grandson Yang Wenguang became distinguished generals. Folklore transformed their history into the legendary tales of the “Yang Generals,” inventing heroic female warriors and vilifying Pan Mei as the traitor “Pan Renmei.” While historically Pan Mei was a capable general whose error was grave but not treasonous, the story of his failure to rescue Yang Ye cemented his infamy in popular culture.
Following this devastating defeat, Emperor Taizong became terrified of the Liao, abandoning any further thoughts of northern expeditions. The Song military developed a “fear of Liao” syndrome. Concurrently, internal rebellions, such as those led by Wang Xiaobo and Li Shun in Sichuan, forced the court to adopt a policy of “Guarding the Interior while Neglecting the Exterior”. This strategy prioritized internal stability over external expansion, effectively ending Song ambitions to recover the lost territories, while the Liao continued their periodic incursions.
