Deng Ai (197–264),^[1] courtesy name Shizai, was a military general of the state of Cao Wei in the Three Kingdoms period. He is best known for his pivotal role in the Wei conquest of its rival state, Shu Han, in 263. He was described as a very loyal subject who made great contributions to Wei, but was also noted for his arrogance and audacity, which led to his downfall and death.

Born in a peasant family, Deng Ai started his career as a minor agricultural officer. Sometime between 235 and 239, he met Sima Yi, who recognised his talent and gave him a higher position in the civil service. Around this time, he also wrote a proposal on starting agricultural works in the Huai River region, and received credit for his ideas. Deng Ai gained greater prominence in Wei from 249 onwards after he joined the Wei general Guo Huai in stopping a Shu invasion. He also advised the regent Sima Shi on some issues. In 255, he participated in the suppression of a rebellion started by the generals Guanqiu Jian and Wen Qin, and was promoted to the status of a top general. From 255 to 262, he defended Wei's western borders in present-day Gansu from multiple incursions by the Shu forces led by the general Jiang Wei.

Deng Ai reached the pinnacle of his career in 263, when he led Wei forces to conquer Shu. By leading a strike force through a shortcut across dangerous mountainous terrain, Deng Ai showed up in the vicinity of the Shu capital, Chengdu, and took the enemy by surprise. After a failed attempt by the Shu general Zhuge Zhan to stop Deng Ai at Mianzhu, the Shu emperor Liu Shan voluntarily surrendered to Deng Ai and brought an end to the Shu state. Following his success in the Shu campaign, Deng Ai became arrogant about his achievements and showed disregard for the Wei government's authority. The Wei general Zhong Hui exploited and manipulated Deng Ai's arrogance to great effect. In 264, Deng Ai was arrested by Wei Guan and Zhong Hui, who were acting under order by the Wei regent Sima Zhao. He was placed in a prison cart and escorted to the capital Luoyang, but was killed en route by soldiers sent by Wei Guan. His sons were executed as well. His surviving family members were exiled but allowed to return in 265 after the Jin dynasty was established.

Early life and career

Deng Ai was from Jiyang County (棘陽縣), Yiyang Commandery (義陽郡), which is in present-day Xinye County, Nanyang, Henan. He was born towards the end of the Eastern Han dynasty and lost his father at a young age. When the warlord Cao Cao conquered northern Jing Province in 208, Deng Ai moved to Runan Commandery (汝南郡; in present-day southern Henan), where he lived as a farmer and raised cattle. When he was 11 years old, he and his mother passed by Chen Shi's tomb in Yingchuan Commandery (潁川郡; around present-day Xuchang, Henan). He read two lines engraved on Chen Shi's tombstone: "his writings became examples of excellent prose; his conduct served as a role model for officials" (文為世範，行為士則). He was so inspired that he wanted to change his given name to Fan (lit. "(role) model") and his courtesy name to Shize (lit. "for officials to emulate"). However, since the names Fan and Shize were already used by members of his extended family, he could not change his names as such because it would violate naming taboo.^{[Sanguozhi 1]}

Deng Ai later became an Academician (學士) under the local Commandant (都尉) in Xiangcheng (襄城; present-day Xiangcheng County, Xuchang, Henan). However, he was not too successful in his career because he stuttered in his speech. He then switched his job to a "daotian shou congcao li" (稻田守叢草吏; an agricultural officer in charge of grain and fodder). The locals pitied him for his poor family background and often provided him with financial aid. Deng Ai initially did not show any form of gratitude towards them. Whenever he saw mountains and lakes, he started gesturing and pointing out how and where he believed army camps should be laid out, but was scorned by others. Later on, he was promoted to "diannong gangji" (典農綱紀) and "shangji li" (上計吏), which put him in charge of maintaining records of agricultural output.^{[Sanguozhi 2]}

Deng Ai was acquainted with Shi Bao (石苞), who was about the same age as him. They were quite close to Guo Xuanxin (郭玄信), who served as an Internuncio (謁者). When Ji Ben, an Imperial Physician, started a rebellion in Xu (許; present-day Xuchang, Henan) in 218, Guo Xuanxin was implicated and initially placed under house arrest, until an officer came to escort him to the imperial court. Deng Ai and Shi Bao were among the escorts. While travelling for about ten li, Guo Xuanxin chatted with them along the way and remarked that the two of them would become very capable officials in the future. Deng Ai was later promoted to the rank of an "Agricultural Officer of Merit" (典農功曹).^{[Sanguozhi zhu 1]}

Sometime between 235 and 239,^{[lower-alpha 3]} he was sent as a messenger to the capital, Luoyang, where, by chance, he met Sima Yi, who was then serving as the Grand Commandant (太尉) under the Cao Wei government. Sima Yi felt that Deng Ai was an extraordinary person so he recruited him and promoted him to the position of a "Gentleman Cadet in the Imperial Secretariat" (尚書郎).^{[Sanguozhi 3]}

Agricultural and irrigation projects

Around the time, the Cao Wei state was planning to promote agriculture and stockpile food resources in preparation for military campaigns against its rival states, Shu Han and Eastern Wu. Deng Ai was sent to survey the lands from the east of Chen (陳) and Xiang (項) commanderies (around present-day Zhoukou, Henan) to Shouchun Commandery (壽春郡; around present-day Shou County, Lu'an, Anhui), and assess their suitability for agriculture. He saw that the lands were fertile but lacked moisture, so they were not fully utilised. He suggested to dig irrigation channels to irrigate the land, and open up new canals for transporting goods by water.^{[Sanguozhi 4]}

Deng Ai wrote a proposal, the Ji He Lun (濟河論; Discussion on the River), to explain his ideas. He said, "The tuntian system started when the Yellow Turban Rebellion broke out. There are a lot of food supplies stored in the capital, Xu. Even though most of the Empire has been pacified now, the lands south of the Huai River are still ravaged by war. Every time a southern campaign is launched, about half the manpower is used for transporting supplies. The lands between Chen and Cai commanderies are fertile, so we can reduce the number of grain fields around Xu and direct the river flow east to Chen and Cai commanderies. At the moment, there are 20,000 troops stationed north of the Huai River, and 30,000 at the south. There are about 40,000 active soldiers guarding territory and farming at the same time. In good weather, the harvest is three times of that in the western lands. After deducting allowances for the people and soldiers, we have about five million hu (斛) of grain ready for military use. Within six to seven years, we can accumulate 30 million hu of grain on the upper part of the Huai River. This amount of grain is able to feed 100,000 people for up to 15 years. With such abundant food supplies, we can attack Eastern Wu and secure victory!" Sima Yi agreed with Deng Ai's proposal and implemented his ideas.^{[Sanguozhi 5]}

In 241, the agricultural projects were complete. Whenever there were battles in the southeast between Wei and Wu, the Wei forces could sail down the river towards the Huai River region to counter the enemy. This was because they had plenty of food supplies stockpiled upstream and had the water pathways to their advantage. Deng Ai received credit for his proposal.^{[Sanguozhi 6]}

Battle of Tao River

Deng Ai later became a military adviser to the Wei general Guo Huai and was promoted to serve as the Administrator (太守) of Nan'an Commandery (南安郡; around present-day Longxi and Wushan counties, Gansu). In 249, he followed Guo Huai to resist an invasion led by the Shu general Jiang Wei. After the Shu forces were repelled, Guo Huai advanced west to attack the Qiang tribes. Deng Ai cautioned him, "The enemy did not retreat far. They might turn back to attack us again, so we should split up our forces in case they attack us again."^{[Sanguozhi 7]}

Deng Ai remained behind and garrisoned at the north of Baishui (白水; around present-day Baishui County, Weinan, Shaanxi). Three days later, Jiang Wei sent Liao Hua to lead a force to approach Deng Ai's camp from the south of Baishui. Deng Ai told his officers, "Jiang Wei has turned back to attack us. We have few troops. Ideally, we should cross the river and not build a bridge. I believe Jiang Wei must have sent Liao Hua to hinder us so that we are forced to remain here, while he would attack Taocheng (洮城) from the east." Taocheng was located north of the river and was about 60 li away from Deng Ai's position. Deng Ai immediately dispatched troops to travel overnight to Taocheng to defend the fortress. As he expected, Jiang Wei crossed the river to attack Taocheng, but failed to capture the fortress because Deng Ai had already strengthened its defences. For his achievements, Deng Ai was enfeoffed as a "Secondary Marquis" (關內侯), awarded the rank of "General Who Attacks Rebels" (討寇將軍), and subsequently appointed as the Administrator of Chengyang Commandery (城陽郡; around present-day Zhucheng, Weifang, Shandong).^{[Sanguozhi 8]}

Advice on guarding against the Xiongnu

Around the time, the Xiongnu prince Liu Bao, who was nominally a vassal under the Wei government, was gradually building up his military forces in Bing Province. Deng Ai wrote a memorial to the Wei imperial court: "The barbarians have the hearts of beasts and cannot be reasoned with. When they are powerful, they become violent; when they are weak, they pledge allegiance to the imperial court. This was why King Xuan of Zhou was attacked by the Rongdi while Emperor Gao of Han was besieged in Pingcheng. Whenever the Xiongnu grew powerful, the previous dynasties always saw them as a great threat. When the chanyu (Xiongnu ruler) lived in the barbarian lands, the imperial court could not directly control the chanyu and his followers. However, when the chanyu was lured to our territory to become a subject of the imperial court, the Xiongnu lost their leadership and could not cause trouble. As of now, as the chanyu has been living in the capital all this time, he has been alienated from his followers. At the same time, the Xiongnu prince Liu Bao has been living at the border and his military power has been increasing and he poses a threat to the imperial court. We should take extra precautionary measures against him. I heard that there are rebels within Liu Bao's domain, so we can try to split up his domain and hence reduce his military power. The Xiongnu prince rendered meritorious service to the previous dynasty, but his son was not allowed to inherit his domain. We should grant him an honorary title and let him remain at Yanmen Pass. The best strategy to maintain peace at the borders is to isolate the barbarian leaders from their home territories and give them some rewards for their past contributions."^{[Sanguozhi 9]}

Deng Ai also suggested: "We should gradually segregate those Han Chinese living with barbarians, inculcate moral values such as integrity in them, so as to prevent them from resorting to unlawful actions." Sima Shi, the General-in-Chief (大將軍) who had recently taken over the reins of power as the regent of Wei, accepted Deng Ai's suggestions. He also appointed Deng Ai as the Administrator of Runan Commandery (汝南郡; in present-day southern Henan), where Deng lived in his younger days. Upon arriving in Runan to take office, Deng Ai sought a man who generously helped his father before because he wanted to repay that man for his kindness. However, he was disappointed to learn that the man had already died, so he sent his subordinates to pay respects at the man's tomb on his behalf. He also gave many gifts to the man's mother and recruited the man's son to be an accounting officer under him. During his tenure, Deng Ai developed wastelands in Runan and ensured that his soldiers and the common people had their basic needs fulfilled.^{[Sanguozhi 10]}

Giving advice to Sima Shi

When the Eastern Wu general Zhuge Ke retreated after a failed attempt to capture the Wei-controlled fortress at Hefei, Deng Ai approached the Wei regent Sima Shi and said, "Sun Quan is dead and most of the Wu officials are undecided yet on whose leadership to follow. Many Wu nobles and aristocrats have their own followers and private armies, and are capable of seizing the mandate to rule Wu. Zhuge Ke may have recently taken control of the Wu government, but he has no backing from the ruler. Besides, he cares little about consolidating power and instead treats the people harshly and continue to fight a war with us. He mobilised the people of Wu to attack our fortress and failed to conquer it after sustaining heavy losses. This is when he becomes an enemy of his own people. In the past, Wu Zixu, Wu Qi, Shang Yang and Yue Yi rose to prominence because they were favoured by their respective rulers, and they met their downfall after the ruler's death. Zhuge Ke is not only not comparable to these four great men, but also unaware that he is getting himself into deep trouble. His downfall is imminent." As Deng Ai foresaw, Zhuge Ke was ousted from power not long after he returned to Wu and was killed along with his family.^{[Sanguozhi 11]}

Deng Ai was appointed as the Inspector (刺史) of Yan Province (兖州) and promoted to the position of "General Who Inspires Might" (振威將軍). He wrote a memorial to the Wei imperial court: "The most important policy areas are agriculture and war. If the state is wealthy, the army will be powerful. If the army is powerful, it will win battles. Therefore, the key to victory lies in agriculture. Confucius mentioned before, 'abundance in food supplies and number of troops'. Having abundant food supplies is important to maintaining a powerful army. If the state does not designate any officials to be in charge of collecting taxes and food supplies, there will be no one to accumulate wealth from the masses. As of now, the system of giving rewards based on merit is aimed at collecting food supplies and distributing them to the people. If not, the state will break off all its trade routes with the outside world, and a wealthy and prosperous state will become isolated."^{[Sanguozhi 12]}

Helping to suppress the second Shouchun rebellion

Deng Ai was enfeoffed as the "Marquis of Fangcheng Village" (方城亭侯) after Cao Mao became the new Wei emperor in 254. In the following year, when the Wei generals Guanqiu Jian and Wen Qin started a rebellion in Shouchun Commandery (壽春郡; around present-day Shou County, Lu'an, Anhui),^[3] they sent messengers to other areas to incite the people to join their rebellion. Deng Ai arrested and executed the messengers, and then led troops to suppress the rebellion. His force occupied Yuejia (樂嘉; present-day Xiangcheng City, Zhoukou, Henan) and started building pontoon bridges. When the main Wei army led by Sima Shi showed up, Deng Ai rendezvoused with him and they advanced towards Shouchun together. The rebels were subsequently defeated. Deng Ai pursued the fleeing Wen Qin to Qiutou (丘頭; southeast of present-day Shenqiu County, Zhoukou, Henan), but Wen still managed to escape and defect to Wei's rival state, Eastern Wu.^{[Sanguozhi 13]}

The Wu general Sun Jun led thousands of troops and crossed the Yangtze River to support the rebels. The Wei general Zhuge Dan ordered Deng Ai to resist the enemy at Feiyang (肥陽), but Deng saw that if he was stationed in Feiyang he would be in a disadvantageous position, so he relocated his troops to a neighbouring village. He then sent Zhuge Xu to attack the remaining rebels and Wu forces at Lijiang Village (黎漿亭; southeast of present-day Shou County, Lu'an, Anhui), where they defeated the enemy.^{[Sanguozhi 14]}

In the same year, Deng Ai was promoted to "Colonel of Changshui" (長水校尉). Later on, for his contributions in suppressing the rebellion, he was further promoted to acting-"General Who Pacifies the West" (安西將軍) and his marquis rank was increased by one grade to "Marquis of Fangcheng District" (方城鄉侯).^{[Sanguozhi 15][4]}

Battle against Shu

Around 255, the Shu general Jiang Wei led forces to attack Wei and besieged Wang Jing, the Inspector of Yong Province, in Didao (狄道; southwest of present-day Lintao County, Gansu). The Wei imperial court appointed Deng Ai as "General Who Pacifies the West" (安西將軍) and "Colonel Who Protects the Eastern Qiang" (護東羌校尉) to lead troops to lift the siege. By then, Jiang Wei had withdrawn to Zhongti (鍾提; south of present-day Lintao County, Gansu), so many of Deng Ai's subordinates thought that Jiang Wei was exhausted and would not attack Didao again. However, Deng Ai held a different opinion and he said, "The defeat at Taoxi (洮西) was not an insignificant loss. The loss of troops and officers, depletion of stores and reserves, and displacement of refugees are signs pointing towards imminent destruction. I shall explain the situation. Firstly, the enemy is riding on a wave of victories, while we are actually weak. Secondly, the enemy forces are well-trained and battle-ready, while ours are newly recruited and not well-equipped. Thirdly, the enemy is less tired than us because we travel by land whereas they travel by water. Fourthly, the enemy focuses on attacking Didao only, while we spread our defences across four locations – Didao, Longxi (隴西), Nan'an (南安; southeast of present-day Longxi County, Gansu) and Mount Qi (祁山; the mountainous regions around present-day Li County, Gansu). Fifthly, Nan'an and Longxi have grain produced by the Qiang people, while there are fields of wheat beyond Mount Qi. The enemy is cunning. They will definitely come for the wheat." As Deng Ai predicted, Jiang Wei led his forces to attack Mount Qi later but were repelled by the defences set up by Deng. Jiang Wei retreated to Dong Village (董亭; south of present-day Wushan County, Gansu), while Deng Ai stationed his troops at Mount Wucheng (武城山). Jiang Wei tried to seize control of the mountainous terrain from Deng Ai, but was driven back. That night, Jiang Wei attempted to cross the Wei River to attack Shanggui (上邽; present-day Tianshui, Gansu). Deng Ai intercepted Jiang Wei at Duan Valley (段谷; southwest of present-day Tianshui, Gansu) and defeated him.^{[Sanguozhi 16]}

In 256, the Wei imperial court issued an edict as follows: "The cunning enemy Jiang Wei has been inciting the local tribes to rebel against the government, resulting in chaos in the western lands. Deng Ai planned his strategies well, and displayed courage and loyalty in battle. He defeated tens of enemy officers and killed thousands of enemy troops. Our state has caused the Bashu region to tremble in fear, while our military might spreads beyond the rivers. Deng Ai is hereby appointed as "General Who Guards the West" (鎮西將軍) and put in charge of overseeing military affairs in Longyou. He shall also be enfeoffed as the "Marquis of Deng" (鄧侯), and given 500 taxable households as his marquisate. His son, Deng Zhong, shall be enfeoffed as a village marquis (亭侯)."^{[Sanguozhi 17]}

In the following year, Deng Ai defeated Jiang Wei in battle again along the Great Wall and forced him to retreat back to Shu. He was further promoted to "General Who Attacks the West" (征西將軍), and had the number of taxable households in his marquisate increased to 6,600. In 262, he defeated Jiang Wei in battle at Houhe (侯和). Jiang Wei retreated to Tazhong (沓中; northwest of present-day Zhugqu County, Gansu) and garrisoned there.^{[Sanguozhi 18]}

Conquest of Shu by Wei

Strategic planning and opening moves

In the autumn of 263, the Wei imperial government started mobilising troops in preparation for a campaign against Shu. Sima Zhao, who oversaw the campaign, ordered Deng Ai to lead 30,000 troops^{[Sanguozhi 19]} to Tazhong (沓中; northwest of present-day Zhugqu County, Gansu) to harass Jiang Wei and keep him occupied, while Zhuge Xu, the Inspector of Yong Province, would lead forces to block Jiang Wei's retreat route back to Shu.^{[Sanguozhi 20]} Before Deng Ai embarked on the campaign against Shu, he dreamt of himself sitting on a mountaintop with water flowing near him. He asked an official, Yuan Shao (爰邵), who was well-versed in the Yijing, to explain to him what his dream meant. Yuan Shao told him that he would successfully conquer Shu, but would not return to Wei. Deng Ai felt gloomy after hearing this.^{[Sanguozhi 21]}

Deng Ai sent Wang Qi (王頎; the Administrator of Tianshui) to lead troops attack Jiang Wei's camp directly, with Qian Hong (the Administrator of Longxi (around present-day Longxi County, Gansu)) leading another force to clear the path, and Yang Xin (楊欣; the Administrator of Jincheng) to attack the enemy positions at Gansong (甘松; around present-day Songpan County, Sichuan).^{[Sanguozhi 22]}

When Jiang Wei received news that another Wei army led by Zhong Hui had occupied Hanzhong, he led his troops from Tazhong back further into Shu territory, but was pursued by Yang Xin to Qiangchuankou (彊川口), where he was defeated. Jiang Wei learnt that Zhuge Xu's force had blocked his retreat route at the bridge, so he led his men through Konghan Valley (孔函谷; south of present-day Xigu District, Gansu) to the northern road in an attempt to bypass Yong Province. When Zhuge Xu heard about it, he retreated back by 30 li. By then, Jiang Wei and his troops had travelled about 30 li on the northern road when they heard that Zhuge Xu had lifted the blockade at the bridge. Jiang Wei ordered his troops to quickly pass the bridge. Zhuge Xu tried to turn back to block Jiang Wei again but arrived at the bridge one day too late. After crossing the bridge, Jiang Wei moved to Jiange (劍閣; present-day Jiange County, Sichuan) and garrisoned there. Zhong Hui attacked Jiang Wei at Jiange several times but was unable to breach the defences.^{[Sanguozhi 23]}

Capture of the Shu capital

Deng Ai proposed, "The enemy has suffered a setback. We should take advantage of our success to press on the attack. From Yinping (陰平; northwest of present-day Wen County, Longnan, Gansu), there is a shortcut passing through Deyang Village (德陽亭; around present-day Deyang, Sichuan) to Fucheng (涪城; present-day Fucheng District, Mianyang, Sichuan), leading to an area 100 li west from Jiange and about 300 li from Chengdu, the heartland of Shu. We can send a strike force to take this route to attack Chengdu. When Fucheng is under attack, Jiang Wei will definitely send troops from Jiange to reinforce Fucheng, and then Zhong Hui's army can move through the main road to attack the enemy. If Jiang Wei does not send reinforcements from Jiange, Fucheng will be isolated. As military texts say, 'Attack the enemy where they are unprepared, and appear where you are not expected'. If we can strike the enemy at their weak points, we will eventually overcome them."^{[Sanguozhi 24]}

In the winter of 263, Deng Ai led a strike force from Yinping through the shortcut over a distance of more than 700 li. As the shortcut passed through mountainous terrain, they had to construct several bridges along the way. The mountains were high and the valleys were deep, which made the journey extremely dangerous. After some time, they were completely cut off from their supply train. Deng Ai wrapped himself in a large piece of felt and rolled down the mountain. His men climbed trees and scaled cliffs in single file. Deng Ai and his strike force showed up at Jiangyou and caught the defending Shu officer, Ma Miao, by surprise. Ma Miao surrendered to Deng Ai.^{[Sanguozhi 25]}

The Shu general Zhuge Zhan led an army from Fucheng to Mianzhu Pass (綿竹關; in present-day Mianzhu, Deyang, Sichuan), where they engaged Deng Ai and his troops in battle. Deng Ai ordered his son Deng Zhong to flank the enemy from the right, and Shi Zuan to flank the enemy from the left. Both Deng Zhong and Shi Zuan were driven back by Zhuge Zhan, and they told Deng Ai, "The enemy cannot be defeated.". Deng Ai angrily said, "This battle will determine whether we live or die. What do you mean when you say the enemy cannot be defeated?" He wanted to execute them, but they turned back and hastily readied their troops for battle again. They defeated the Shu forces and killed the enemy officers Zhuge Zhan, Zhuge Shang and Zhang Zun.^{[Sanguozhi 26]}

Deng Ai and his men then pressed on further to Luo County (雒縣; north of present-day Guanghan, Sichuan). Liu Shan, the Shu emperor, sent an emissary to present his imperial seal to Deng Ai and indicate his wish to surrender.^{[Sanguozhi 27]}

Managing post-war Shu

When Deng Ai arrived in Chengdu, Liu Shan tied himself up and led an entourage of over 60 people to officially surrender. Deng Ai freed Liu Shan from his bonds and treated him kindly. He also forbid his soldiers from plundering and pillaging the city, and ordered that daily activities in the city resume as per normal. Many former Shu officials were so impressed with Deng Ai that they willingly submitted to him, while the people of Shu also praised Deng. Using the actions of the Eastern Han dynasty general Deng Yu as a precedent, Deng Ai appointed Liu Shan as acting-"General of Chariots of Cavalry" (驃騎將軍) under the Wei imperial court. The various former Shu nobles and officials were also given new appointments in the Wei administration, while some became Deng Ai's subordinates. Deng Ai appointed Shi Zuan as Inspector of Yi Province, and put Qian Hong in charge of overseeing the former Shu commanderies. A memorial site was constructed at Mianzhu Pass to glorify Deng Ai's victory over Zhuge Zhan. The fallen Wei soldiers were buried together with their counterparts from Shu.^{[Sanguozhi 28]}

Deng Ai became arrogant about his achievements in conquering Shu. He once bragged to the former Shu officials, "All of you are lucky to have encountered me, which is why you are where you are today. If you encountered someone like Wu Han, you would have been destroyed." He also said, "Jiang Wei is a short-term hero. He pales in comparison with me." Some people scorned him for his boastfulness.^{[Sanguozhi 29]}

In the 12th lunar month of 263, the Wei imperial court issued an edict praising Deng Ai for his successful conquest of Shu and comparing him to famous generals such as Bai Qi, Han Xin, Wu Han and Zhou Yafu. Deng Ai was promoted to the position of "Grand Commandant" (太尉) in the imperial court and had the number of taxable households in his marquisate increased by 20,000. His two sons were made village marquises (亭侯) and given 1,000 taxable households each in their marquisates.^{[Sanguozhi 30]}

Downfall and death

Correspondence between Deng Ai and Sima Zhao

Deng Ai wrote to Sima Zhao, suggesting that they let the weary troops rest and recuperate while concurrently making preparations for a future campaign against Wei's other rival state, Eastern Wu. He also proposed that Liu Shan be treated generously by making him a prince and showering him with luxuries. The purpose of doing so was to induce and tempt Sun Xiu, the Wu emperor, into voluntarily surrendering to Wei.^{[Sanguozhi 31]}

Sima Zhao sent Wei Guan to reply Deng Ai that his proposal would be submitted to the Wei imperial court for further deliberation before it could be implemented.^{[Sanguozhi 32]} Deng Ai grew impatient and argued that they would be wasting time if they had to wait for further instructions from the imperial court before taking action. He cited lines from the Spring and Autumn Annals and The Art of War to hint that he was justified in ignoring standard protocol and acting autocratically as long as what he did was to Wei's benefit.^{[Sanguozhi 33]}

Zhong Hui's role in Deng Ai's arrest

Zhong Hui, Hu Lie (胡烈), Shi Zuan (師纂) and others accused Deng Ai of showing disrespect for the imperial court's authority, and claimed that he was likely to rebel against Wei.^{[Sanguozhi 34]} The Shiyu mentioned that Zhong Hui was skilled in imitating people's handwriting. After getting his hands on a letter written by Deng Ai to Sima Zhao,^{[lower-alpha 4]} he edited it to make it sound arrogant and demanding. At the same time, he also destroyed a letter from Sima Zhao to Deng Ai to increase Sima's suspicions towards Deng.^{[Sanguozhi zhu 2]}

In the first lunar month of 264,^[2] the Wei imperial court then issued an edict ordering Deng Ai to be arrested and transported back to the capital, Luoyang. Wei Guan and Zhong Hui went to Deng Ai's camp, where they used Sima Zhao's letter of authorisation to order Deng's men to put down their weapons. Deng Ai was arrested and placed in a prison cart for his journey to Luoyang.^{[Sanguozhi 35]} When he was arrested, Deng Ai exclaimed, "I am a loyal subject, yet I meet with such a fate! Whatever that happened to Bai Qi in the past has just happened to me in the present."^{[Sanguozhi zhu 3]}

Death

After Deng Ai was escorted away, Zhong Hui started a rebellion against Wei in Chengdu, but the rebellion failed when some Wei officers, who were unwilling to participate, mutinied against Zhong and killed him. After Zhong Hui's death, Deng Ai's subordinates caught up with the convoy escorting their general, freed him, and brought him back to Chengdu. When Wei Guan heard about it, he ordered Tian Xu (田續) to lead troops to attack Deng Ai.^{[Sanguozhi 36]}

Tian Xu had initially served under Deng Ai during the campaign against Shu. During an earlier battle at Jiangyou, Deng Ai wanted to execute Tian Xu for delaying his advance against the enemy, but spared him eventually. When Wei Guan sent Tian Xu to attack Deng Ai, he told Tian, "You can now take revenge against Deng Ai for how he humiliated you at Jiangyou."^{[Sanguozhi zhu 4]}

Tian Xu and his soldiers intercepted Deng Ai at the west of Mianzhu Pass (綿竹關; in present-day Mianzhu, Deyang, Sichuan) and killed him along with his son, Deng Zhong, and Shi Zuan.^{[Sanguozhi zhu 5]} After Deng Ai's death, his other son(s) in Luoyang was/were also rounded up and executed, while his surviving family members were exiled to the Western Regions.^{[Sanguozhi 37]}

Posthumous rehabilitation and legacy

In 265, after the Jin dynasty replaced the Wei regime, Emperor Wu of Jin issued an imperial edict to pardon Deng Ai's descendants and allow them to return from exile. He noted that Deng Ai was fairly punished for his arrogance and audacity, but the "redeeming factor" was that Deng Ai did not resist arrest and willingly resigned to his fate.^{[Sanguozhi 38]}

When Deng Ai was stationed in Yong and Liang provinces, he strengthened the parapets in the area and had some forts constructed for defensive purposes. During the mid-Taishi era (265–274) in Emperor Wu's reign, the Qiang tribes in Yong Province rebelled against Jin rule and killed the Inspector of Liang Province. The surviving officials and local residents found safety in the forts built by Deng Ai about a decade earlier.^{[Sanguozhi 39]}

Family and descendants

Deng Ai had at least two sons. Two of his sons – one of whom was Deng Zhong – held village marquis titles and owned marquisates of 1,000 taxable households. Deng Zhong was killed along with his father. Deng Ai's other sons who were in Luoyang were arrested and executed in the aftermath of their father's death. Deng Ai's surviving family members were exiled and allowed to return only in 265 after Emperor Wu of the Jin dynasty issued an imperial edict pardoning them.

In 273, Emperor Wu appointed Deng Ai's grandson, Deng Lang (鄧朗), as a langzhong (郎中).^{[Sanguozhi 40]} Deng Lang served as the Prefect (令) of Danshui County (丹水縣; around present-day Xichuan County, Henan) and then as the Prefect of Dingling County (定陵縣; around present-day Qingyang County, Anhui). He had at least one son, Deng Tao (鄧韜). During the Yongjia era (307–313) in the reign of Emperor Huai, Deng Lang was appointed as the Administrator (太守) of Xindu Commandery (新都郡; around present-day Guanghan, Sichuan). However, before he left to assume office, he died in a fire in Xiangyang Commandery along with his mother, wife and children. Only his grandson Deng Xing (鄧行), Deng Tao's son, survived the fire.

Deng Qianqiu (鄧千秋), another grandson of Deng Ai, was recruited to serve under Wang Rong, a prominent Jin dynasty official. He died before Deng Lang while his two sons also perished in the Xiangyang fire.^{[Sanguozhi zhu 6]}

Appraisal

Chen Shou (233–297), who wrote Deng Ai's biography in the Records of the Three Kingdoms (Sanguozhi), commented on Deng Ai as follows: "Deng Ai was upright and strong. He achieved many successes, but failed to protect himself from hidden pitfalls and dangers, which resulted in his eventual downfall. He could envision what would happen to Zhuge Ke, yet ironically could not foresee his own fate. This was probably what the ancients called 'lack of self-awareness and narrow-mindedness'."^{[Sanguozhi 41]}

In 267, Duan Zhuo (段灼) wrote a memorial to Emperor Wu of the Jin dynasty to speak up for Deng Ai. In the memorial, Duan Zhuo discussed Deng Ai's contributions to Wei and argued that Deng had no intention of rebelling against Wei. He also mentioned that Deng Ai had been deeply misunderstood because of his boorish and uncouth behaviour, which made him likely to offend people easily. Duan Zhuo also compared Deng Ai to Bai Qi and Wu Zixu, two generals in the Spring and Autumn period who made great contributions to their respective states but were forced to commit suicide.^{[Sanguozhi 42]}

During the mid-Xianning era (275–280) in Emperor Wu's reign, Fan Zhen (樊震), a general who previously served under Deng Ai during the Wei campaign against Shu, had an audience with the emperor. When Emperor Wu asked about Deng Ai, Fan Zhen became very emotional and he recalled that Deng Ai was a very loyal subject to Wei.^{[Sanguozhi zhu 7]}

Modern references

Deng Ai is first introduced as a playable character in the seventh instalment of Koei's Dynasty Warriors video game series. In the game, he is erroneously associated with the Jin dynasty faction; historically, he died one year before the Jin dynasty was established.

Notes

1. Deng Ai's birth year is not clearly stated in the Sanguozhi. However, his biography in the Sanguozhi mentioned that he was 12 years old (by East Asian age reckoning) around the time when Cao Cao conquered Jing Province in 208 CE. If we assume that Deng Ai was 11 years old in 208 CE, by calculation, his birth year should be in 197 CE.
2. The Zizhi Tongjian makes it clear that Deng Ai died in 264 CE. However, his birth year is not incontrovertibly accepted to be 197 CE. Therefore, 66, the age at which he died, would only make sense if we assume his birth year to be 197 CE.
3. Vols. 73–74 of the Zizhi Tongjian mentioned that Sima Yi was appointed as "Grand Commandant" (太尉) in 235 and he held office until his replacement by Man Chong in 239. Therefore, the time when Deng Ai first met Sima Yi should probably be in between 235–239.
4. It is not clear whether this letter refers to either of the two letters written by Deng Ai to Sima Zhao, or another letter.
