The campaign of 429 was the heaviest blow that any Chinese state struck against the Rouran in the century and a half of the khaganate.[1] The Wei Shu describes it as the Wei state wished it to be remembered: a march across the desert into the enemy’s heart.[1] It followed five years of war with Datan. The war had begun in 424, when the khan’s horsemen surrounded the young emperor at Yunzhong fifty ranks deep. In 425 it had produced a five-road campaign that found no one to fight.[1]

Decision

In the fourth month of 429 Taiwu drilled his army in the southern suburb of Pingcheng, meaning to surprise Datan.[1] The ministers were all against the campaign. The diviners Zhang Yuan and Xu Bian argued from the heavens that he should stop. Taiwu followed the counsel of Cui Hao and went.[1] An envoy returning from the south reported that the Song emperor Liu Yilong meant to attack south of the Yellow River.[1] Liu Yilong had told the envoy to hurry home and tell the ruler of Wei to give back the land south of the river or face the whole strength of his army.[1] Taiwu laughed. He told the court that the little turtle could not save himself, let alone come.[1] If the Song emperor did come and the Rouran had not first been destroyed, the Wei would be waiting for a raider with an enemy at front and back. That was no strategy. He concluded: “My going is decided.”[1]

March

The emperor took the eastern road towards the Black Mountain. The prince of Pingyang, Zhangsun Han, took the western road towards Mount Da’e. The two columns were to meet at the enemy’s court.[1] In the fifth month they halted south of the desert. They left the baggage and struck with light troops, and they reached the Li river. Datan’s people fled west.[1] Datan’s brother Pili commanded the eastern camps. He was bringing them to join the khan when he ran into Zhangsun Han’s column. The column loosed its horse on him and killed several hundred of his chiefs.[1] Datan heard the news and was seized with terror. He took his clan, burned his tents and dwellings, and fled west. He left no trace, and no one knew where he had gone.[1] The tribes scattered and hid in the mountain valleys. Their herds lay spread over the plain with no one to gather them.[1]

Taiwu followed the Li river west and passed the old fortress of the Han general Dou Xian. The fortress was the monument of the campaign of 89 that had broken the northern Xiongnu. Under the Hou Han Shu, Turkic Atlas records that campaign.[1] In the sixth month he halted at the Tuyuan river, three thousand seven hundred li from Pingcheng. There he divided the army to search and sweep.[1] The army swept east to the Hanhai, west to the Zhangye river and north across the Yanran mountains. The area covered five thousand li from east to west and three thousand from north to south.[1] The Gaoche tribes turned on Datan’s people and killed them. More than three hundred thousand surrendered. The captives and war horses taken numbered more than a million.[1] In the eighth month the emperor heard that the eastern Gaoche were camped at the Yini marsh, a thousand li from the army. They had great numbers of people and animals. He sent An Yuan and others against them.[1] When An Yuan and the others reached the marsh, several hundred thousand of the Gaoche surrendered at the sight of the army.[1] The chapter on the Gaoche adds what became of them.[1] They were moved to a belt of land a thousand li wide south of the desert. There they rode their high carts, moved in search of water and grazing, and multiplied their herds.[1] Within a few years they had learned to eat grain, and they were sending yearly tribute. As a result, horses, cattle and sheep became cheap in the Wei state, and felt and hides piled up.[1]

Aftermath

Datan’s people were weakened. He fell ill and died, and his son Wuti succeeded him.[1] Two years later Wuti sent tribute. In 434 he married a Wei princess.[1] The year 429 is treated as the critical juncture. In that year the Rouran were seriously defeated, the Gaoche rose against them and submitted to the Wei, and the hitherto successful khan died.[2] After it, the Rouran recovered quickly. By about 434 they attacked the Kidara Huns in Bactria.[2] Alternatively, 429 was Taiwu’s last great campaign. It was a significant victory, but it failed to capture Datan because the emperor hesitated for fear of a trap. In that case Datan died of illness the same year.[3]

Significance

One reckoning dates the heavy defeat of the Rouran to 424.[3] The chapter itself puts Datan’s raid and the siege of the emperor in 424. It puts the five-road campaign in 425 and the crushing blow across the desert in 429. Under the khaganate, Turkic Atlas follows the chapter.[1] The campaign fixed the pattern of Wei–Rouran war for a century. The emperor could cross the desert and scatter the khan’s people. He could not hold the steppe or catch the khan. The people who profited were the Gaoche. They were resettled in their hundreds of thousands inside the Wei frontier and freed of the Rouran. The Tiele who broke out of the khaganate under Afuzhiluo in 487 were the same people a generation on.
