Xiahou Ba

Xiahou Ba's parents were important figures in Cao Wei; his father, Xiahou Yuan, had fought alongside his distant cousin and founder of Wei, Cao Cao, since the start of the civil war, and was one of the most trusted of Cao's generals, while Xiahou Ba's mother was a sister-in-law of Cao Cao. After Xiahou Yuan was killed at Battle of Mount Dingjun in 219 at the hands of Shu general, Huang Zhong, most of his troops were placed under the command of Zhang He upon advice from Guo Huai, while his private militia and guards were succeeded by his five sons. Xiahou Ba displayed great hatred for Shu, and vowed revenge for his father.[2] In 220, Xiahou Yuan's eldest son Xiahou Heng was given his own marquisate and marquis title, so Xiahou Ba inherited his father's marquis title with a stipend of tax revenues from 800 taxable households.[3]

In 230, when the Wei general Cao Zhen proposed a shift from defensive to offensive stance against Shu Han, Lieutenant-General (偏将军) Xiahou Ba was named as the vanguard.[4] He then led a force towards Hanzhong Commandery taking a route through the 330 km Ziwu Trail (子午道), and camped in a crooked gorge, near the Xingshi camp set up earlier by Shu general, Wei Yan. There, Xiahou Ba was identified by the local residents, who reported his presence to the Shu forces, and was under heavy attack. As the main army of Cao Zhen had not caught up with the vanguard, Xiahou Ba was thrown into a grave situation, where he was forced to rely on personal skills to fight his enemies between barricades until Cao Zhen arrived.[5]

The two forces reached a stalemate and the standoff lasted for a few months, but the developments favoured the Shu side as continuous rainfall over a month had rendered narrow valleys impassable, resulting in Wei army's logistical difficulty. In addition to the disadvantageous weather, Wei Yan had penetrated to the Wei army's rear and successfully incited some non-Han tribes to oppose the Wei forces, so Cao Zhen and Xiahou Ba begrudgingly decided to retreat. Since then, Xiahou Ba was appointed General of the Right, and stationed in Longxi Commandery to train troops; he personally cared for his soldiers and established friendly relation with the foreign tribes (Xirong people) of the region hence he acquired their admiration.[6]

In the 240s, Xiahou Ba was enfeoffed as the Marquis of Bochang Village and became a close associate of Cao Shuang, Cao Zhen's son and a regent to the Wei emperor Cao Fang.[7] When Cao Shuang decided to wage war against Shu to enhance his personal influence and reputation, Xiahou Ba was made Protector of the Army and came under command of Xiahou Xuan, who was the marquis's son in the clan.[8] For the ensuing campaign, however, the Wei general Guo Huai, whom Xiahou Ba disliked, had the honour of leading the vanguard. This time, Wei forces chose the shorter Tangluo Trail into Shu territory, but again experienced logistic problems as a long section of the trail had no water source. As a result, the Wei forces had no choice but to retreat, and many soldiers merely died of thirst along the way back. After the war, Guo Huai, due to his timely withdrawal of troops, was granted a higher military authority over Xiahou Ba.[9]

From 244 to 249, Xiahou Ba played into the hands of Guo Huai, who wielded power to temporarily command him when a military crisis arose. In 247, when some tribal leaders rebelled against Wei, Xiahou Ba came under attack by the Shu general Jiang Wei, who came to support the tribes. Together with Guo Huai, Xiahou Ba repelled Jiang Wei's attack and struck back at the rebels, forcing many of them to surrender.[10] However, E Zhesai (蛾遮塞) of the Qiang tribes and Zhi Wudai (治无戴) of the Hu tribes still persevered, so the war was fragmented into battles that dragged on to 248, wherein Jiang Wei again led Shu forces to the aid of the rebels.

At this point, it is clear that Guo Huai, instead of Xiahou Xuan, was the actual commander on the field to give out orders. For instance, when Guo Huai decided to attack Jiang Wei's subordinate, Liao Hua, Xiahou Ba was ordered directly by the decision maker to tail Jiang Wei's main troop to the west.[11] Upon knowing Liao Hua was under attack, Jiang Wei harshly returned to his aide's assistance just as Guo Huai predicted, isolating the rebels from Shu reinforcement.[12] As the Shu commander was worn out from the travel, so was Xiahou Ba, but the glory and merit of subjugating the rebellion went to Guo Huai, who was promoted to a district marquis for his achievements. On the contrary, Xiahou Ba virtually received nothing for his effort in the campaign.[13]

In 249, after a coup d'état by Sima Yi against Cao Shuang, a lot of the latter's affiliates were also put to death; being a close friend and associate of Cao Shuang, Xiahou Ba was sensitive to the political developments and grew suspicious of Sima Yi's faction. Soon, Xiahou Xuan, who had the staff of authority to command troops over Liang and Yong provinces, was ordered to the capital under the guise of a promotion. Fraught with dread, Xiahou Ba discussed the issue with Xiahou Xuan, and persuaded the latter to flee with him to Shu. But Xiahou Xuan refused and said "I won't live as a guest in a kingdom of barbarians!" What further perturbed Xiahou Ba was the person who succeeded Xiahou Xuan's former position was none other than Guo Huai, whom Xiahou Ba had a personal feud with. Therefore, Xiahou Ba embarked on his lone journey into Shu.[14]

On his way to Shu, Xiahou Ba lost his way and went into a dead end in a valley, where he ran out of food and resorted to killing his horse, taking the carcass as a last supper. He kept walking until his legs were crippled, then he laid beneath a shadow projected from a large rock, and asked travellers for direction, but still could not figure out how to get out from the dead end. When the locals reported the presence of a lame beggar who looked like the great general Xiahou Ba who attacked them years ago, the Shu emperor, Liu Shan, hurriedly sent a rescue team to escort his uncle-in-law to the Shu capital, Chengdu.[15]

Years ago, Xiahou Ba's cousin, Lady Xiahou, was abducted by the Shu general Zhang Fei and became his wife. As a consequence, the Liu clan and Xiahou clan were linked together though Liu Shan's marriage with Zhang Fei's daughter.[lower-alpha 1] That was why Liu Shan called his son a grandnephew of the Xiahou family. Whether it was for political reasons or a private family issue, Liu Shan appointed the handicapped Xiahou Ba as General of Chariots and Cavalry in Shu.[16]

Nevertheless, Jiang Wei apparently befriended Xiahou Ba, and the duo went on several campaigns against the state of Wei. The Wei imperial court pardoned Xiahou Ba's sons on account of Xiahou Yuan's role in the founding of Wei. Instead they were exiled to Lelang Commandery in present-day North Korea.[17]

At the time Xiahou Ba was already a sexagenarian, if not a septuagenarian, he was still active in social life. A story about that was recorded in Yi Bu Qijiu Zhuan (益部耆舊傳), which says an eager Xiahou Ba once wanted to befriend Zhang Ni, who was famous for subjugating the southern barbarians and was one of the most celebrated Shu generals back then. When Xiahou Ba first met Zhang Ni, he told him, "Although I'm not close to you, I have already entrusted wholly to you for a long time, I hope you would understand this." Zhang Ni responded, "I don't know you, and you don't know me. The rationale is on the other end, how can you say you rely on me? I hope you save your words and continue this talk three years later." This incident was circulated within Shu, and knowledgeable persons and scholars found this anecdote worthy of Xiahou Ba and Zhang Ni character.[18]

As a newcomer from Wei, Xiahou Ba must have had faced discrimination and distrust from his colleagues, but due to his complicated background, he was trusted by Liu Shan, and highly valued by another defector of Wei, Jiang Wei. Once, Jiang Wei asked Xiahou Ba if Sima Yi, who gained control of Wei court, would attack Shu, Xiahou Ba replied, "they just recently established hegemony, so they will not indulge in foreign affairs. However, there is a young Zhong Hui, who will be a threat to both Wu and Shu."[19][20] Believing Xiahou Ba's views that Sima Yi would not handle border issues for some time, Jiang Wei revived Zhuge Liang's strategy on constantly waging wars against Wei, and brought Xiahou Ba with him on his expeditions. Xiahou Ba distinguished himself in Jiang Wei's greatest victory in his campaigns, which was the Battle of Didao, after that battle, Xiahou Ba was not mentioned again in historic records.
