Military history of the Three Kingdoms

Source: Wikipedia, the free encyclopedia.
Timelapse of the Three Kingdoms era

The military history of the Three Kingdoms period encompasses roughly a century's worth of prolonged warfare and disorder in Chinese history. After the assassination of General-in-chief He Jin in September 189, the administrative structures of the Han government became increasingly irrelevant. By the time of death of Cao Cao, the most successful warlord of North China, in 220, the Han empire was divided between the three rival states of Cao Wei, Shu Han and Eastern Wu. Due to the ensuing turmoil, the competing powers of the Three Kingdoms era found no shortage of willing recruits for their armies, although press-ganging as well as forcible enlistment of prisoners from defeated armies still occurred. Following four centuries of rule under the Han dynasty, the Three Kingdoms brought about a new era of conflict in China that shifted institutions in favor of a more permanent and selective system of military recruitment. This ultimately included the creation of a hereditary military class as well as increasing reliance on non-Chinese cavalry forces and the end of universal conscription.

Recruitment and organization

As the Han dynasty fell into disarray after the Yellow Turban Rebellion, its system of conscription and checks on military leadership broke down, giving local leaders the autonomy to recruit their own personal armies. At the heart of each army was a group of trusted Companions (親近 qinjin) consisting of family members, close friends and clansmen hired by whatever means was available to their lord. Cao Cao's earliest commanders who formed the nucleus of his army were all clansmen (Cao Xiu, Cao Zhen, Cao Chun). There was no need for conscription as the conflicts of the late Han dynasty created willing recruits who sought protection under a strong army. This type of soldier, characterized by a lack of loyalty to state or nation, primarily concerned with survival, made up the majority of the army outside of the leader's close following.[1][2] Due to the lack of loyalty among common troops, acts of heroism and courage were particularly emphasized among commanders who were expected to lead from the front. A typical example of this type of commander would be Dian Wei, a former local bully noted for his great strength, appetite, and his choice of weaponry, two halberds of immense weight, who served under Cao Cao. In 195, he personally led a group of volunteers clad in double armour (兩鎧 liang kai) against Lü Bu's forces while his liege made his escape. He was promoted to colonel of the bodyguard unit known as the Tiger Warriors and later met his death against Zhang Xiu in 197.[3][4] While echoes of Han organization continued through the formal titles of military structure, in effect the wars of the Three Kingdoms were fought between armies of bands led by individuals selected by dint of violence and charisma.[5]

Training

Military training programs for the general populace in the inner provinces were mostly discontinued after 30 AD to reduce the risk of rebellion. The total number of professional soldiers in standing armies in the Eastern Han, including all the smaller groups, amounted to approximately 20,000 soldiers. Expeditions and campaigns relied upon tens of thousands of troops from local militia armies and non-Chinese auxiliaries, supplemented by professional and semi-professional troops. [6] The men in the inner provinces of the empire could be called to serve during emergencies or serve in local militias to fight against bandits, but these men received no formal training or regular exercise. On the other hand, men of the frontier provinces were liable for conscription and military service as before. [7] This had a negative impact on the performance of the Han army, as noted by Ying Shao, who remarked that "sending [such] men into battle without training is just throwing them away".[8] The majority of soldiers recruited during the early stages of the Three Kingdoms period were thus "neither disciplined nor well trained in the use of arms".[9] Formations and drill still existed, but these were the exceptions rather than the norm, and there is no evidence of troops engaging in a regular training system or large scale exercises.[10] Most commanders favored simple rather than complex formations and maneuvers. An example of a formation that did exist is Zhuge Liang's Eight Formation Plan, which included different configurations named after Heaven, Earth, Wind, and Clouds. It is not clear what these designations mean, but the Eight Formation Plan was traditionally a square formation composed of nine divisions in three sections.[11] The lack of training severely constrained the kind of orders a commander could give for his troops to follow. As a consequence of the limited tactical flexibility at their disposal, the majority of battles were carried out in one of two ways: a head on charge by elite shock troops followed by the loosely organized army of incoherent and disparately trained and equipped soldiers, or ambush and surprise the enemy before they could even respond and cause them to rout.[12]

Yuan Shao moved to attack Gongsun Zan and the two sides met in battle twenty li south of Jie Bridge. Gongsun Zan had thirty thousand foot soldiers in square formation and ten thousand horsemen split into left and right wings. His White Cavalry Volunteers followed in the center. They split in two, the left riding right, and the right riding left. Their armour and flags shined with brilliance, lighting up heaven and earth. Yuan Shao sent Qu Yi against them with eight hundred soldiers while a thousand crossbowmen on either side supported his advance. Yuan Shao himself led tens of thousands of soldiers from the rear. Qu Yi had resided in Liangzhou for a long time and was familiar with the way of war as practiced by the Qiang tribes. Seeing Qu Yi's small force, Gongsun Zan sent cavalry to crush them. Qu Yi's troops hid behind their shields and made no move until the enemy were ten or twenty yards away; then they leapt up together, their cries shaking the ground, rushing forward with crossbows shooting bolts like thunder, killing all who were struck, and completely defeated Gongsun Zan's army...... killing more than a thousand armed men, Yuan Shao's troops maintained their pursuit to Jie Bridge. Gongsun Zan rallied his troops to turn and fight, but Qu Yi again defeated them. Reaching Gongsun Zan's camp, they captured his standard and the rest of his army took to flight.[13]

The training that the privileged elite received was far greater in extent compared to that of the common soldier. For example, Cao Cao's son, Cao Pi, started his military education in early childhood. He began training in archery at the age of five, started learning how to ride a horse at the age of six, and could both ride and shoot a target at a hundred paces by the time he was eight.[14] Horse archery was also practiced in Shu Han, which fielded a "Flying Army" of mounted archers.[15]

Hereditary troops

In contrast to the military hierarchy of the Han dynasty, leadership of a unit in the Three Kingdoms was functionally hereditary as long as the successor was loyal to his liege and proved militarily competent. When the commander died, a male member of his family inherited control of his troops, and when a soldier died one of his male relatives inherited his position in the unit. By the end of the Three Kingdoms, the term buqu (部曲) had come to designate the institution of hereditary military leadership. Both bu and qu, meaning battalions and companies, were originally units of military organization during the Han. Under Cao Cao, a more systematic form of hereditary soldiery was implemented through "military families" (士家 shijia) which later became "hereditary troops" (世兵 shibing). As their name implies, able male members born into military families served for life, and when they could no longer serve because of illness or death, their sons or close family members replaced them. Their families lived at the capital and other major centers where they could be used by the government as hostages to ensure the loyalty of their soldiers. They were also forbidden from marrying into non-military families in order to prevent their offspring from exiting the system, thus creating a closed community of military households. Although commoners could still be called up in times of urgent need, the rise of government mandated military communities under

Jin dynasty, had by and large, replaced the universal conscription of the Han.[16]

Tuntian

Tuntian, often rendered as "[military] agricultural colonies," were self-sustaining farming communities created for the purpose of providing food for the military. Generally consisting of displaced peoples, refugees, and bandits, tenants of a tuntian were expected to protect themselves in times of emergencies and in return were exempt from corvée labour. Unlike the tuntian system of the Han dynasty, which was generally hands off, the tuntian policy of the Three Kingdoms era was to directly provide them with supplies and material assistance. The policy of tuntian was implemented primarily by Cao Cao, Tao Qian, and Gongsun Zan.[17]

Equipment

Armies of the Three Kingdoms era used largely the same equipment as the Han dynasty since it directly follows the end of the Han. There were however some minor differences and developments such as the increasing prevalence of armoured cavalry. In one battle, the warlord Cao Cao boasted that with only ten sets of horse armour he had faced an enemy with three hundred sets.[18] The horse armour may however have just been partial frontal barding.[15] Mounting stirrups were already in use, possibly as early as the Han dynasty, but full riding stirrups would not appear until the 4th century.[19] References to "dark armour" (xuan kai or xuan jia 玄鎧/玄甲) and "brilliant armour" also began to appear in the 3rd century. This is probably in reference to the association of high quality steel with black ferrous material.[20]

Weapons were largely the same as well, although there was more focus on idiosyncratic weapons wielded by particularly noteworthy individuals. For example, one man named Chen An apparently wielded a great sword over two meters in length[21] and Sun Quan's wife had over a hundred female attendants armed with daos.[22] Trends in warfare that had already been underway during the Eastern Han continued to gain momentum. By the end of the Three Kingdoms, the single edged dao, with its thicker and more durable dull side, had overtaken the straight double-edged jian as the primary close combat weapon.[23] The more expensive, lighter, and less durable jian entered the domain of court dancers, officials, and expert warriors.[24] While halberds were still used during the period, long spears and lances (similar to pikes) re-rose in prominence over halberds for infantry and cavalry forces. This was believed to have been the result of the long spear and lances' simpler construction, the adoption of long spears and lances by heavy cavalry to strike infantrymen, and the adoption of tighter infantry formations with less room for swinging and hooking [of halberds] in response to the greater threat by cavalry. [23][25] Soldiers in the northeast specialized in long spears.[26] After the Han dynasty, the crossbow gradually faded in importance until it made a mild resurgence during the Tang dynasty, under which the ideal expeditionary army of 20,000 included 2,200 archers and 2,000 crossbowmen.[27]

References to "great shields" occur in their usage on the front line to protect spearmen and crossbowmen. Shields were also commonly paired with the single edged dao and used among cavalrymen.[28] Descriptions of the Battle of Guandu mention that Cao Cao's soldiers employed shield cover above their heads each time they moved out into the open due to oppressive arrow fire from Yuan Shao's wooden towers.[29]

Although Zhuge Liang is often credited with the invention of the repeating crossbow, this is actually due to a mistranslation confusing it with the multiple bolt crossbow. The source actually says Zhuge invented a multiple bolt crossbow that could shoot ten iron bolts simultaneously, each 20 cm long.[30]

Dark armour

A report in 231 AD mentions the capture of 5,000 suits of "dark armour" (xuan kai or xuan jia 玄鎧/玄甲) and 3,100 crossbows. Dark armour appears in Han texts as well, but only as the attire worn by honor guards at funeral processions. The only known trait about dark armour is that it reflected the sun's rays. This probably means dark armour was made of high quality steel, which was often associated with black ferrous material.[20]

Brilliant armour

Cao Zhi mentioned three different kinds of armour, two of which were variants of "brilliant" armour:

The Previous Emperor presented your vassal with armor (kai), to wit, a suit of "black-brilliant" (heiguang) and one of "bright-brilliant" (mingguang) and a suit of "double-faced" (liangtang) armor, but now that the present age is peaceful and the weapons and armor (bingge) are not of use, I request leave to turn them all over to the Armor Board (kaicao) to be taken care of.[31]

— Cao Zhi

Brilliant armour was made of decarburized steel, which shines blue-black when polished, giving it its name. Chen Lin described brilliant armour in the following manner:

As for the armor (kai) then like that of Quegong of the Eastern Barbarians,
It is made of the finest steel refined a hundred times;
The armorer has plied his hammer,
The leather-worker has made the stitching;
[Adorned with] dark feathers the flashing armor (jia)
Gleams and shines, throwing off light.[32]

— Chen Lin

Wheel catapult

Ma Jun, a military engineer serving under Cao Wei, devised a siege weapon which threw large stones using a wheel. This device consisted of a drum wheel attached with a curved knife. When rotated, the stones which hung on the wheel would be cut loose by the knife and launched. It is not clear how well this device worked in practice. Successful tests with roof tiles instead of stones are mentioned, but according to Liang Jieming, this contraption never made it past the testing phase and could not have been possible with the technology available at the time.[30]

Special weapons

The historical novel Romance of the Three Kingdoms attributes a number of fictional weapons, often with special names, to certain individuals. Examples include Liu Bei's "Paired Winding Swords" (雙股劍), Guan Yu's "Green Dragon Crescent Blade" (青龍偃月刀), Zhang Fei's "Eighteen chi Serpent Lance" (丈八蛇矛), Zhao Yun's "Blue Steel Sword" (青釭劍), Cao Cao's "Sword of Heaven" (倚天劍), Sun Jian's "Ancient Ingot Blade" (古錠刀), Cheng Pu's "Ironspine Serpent Lance" (鐵脊蛇矛), and Lü Bu's "Fangtianhua Ji" (方天畫戟), otherwise known as the "Sky Piercer" or "Sky Piercing Halberd". While these are completely fictional, the Records of the Three Kingdoms do mention weapons unique to individuals on at least two occasions: Dian Wei's double halberd which weighed 20 kg[33] and Gongsun Zan's two-bladed spear.[34]

Single combat

The Records of the Three Kingdoms and Annotations to Records of the Three Kingdoms contain two instances of single combat between generals. In 192, after Dong Zhuo had been murdered, Li Jue and Guo Si formed an army to oust Wang Yun and Lü Bu from Chang'an. When Guo Si approached the city from the north, Lü Bu opened the gate and offered to settle the matter by single combat. Guo Si agreed and engaged with Lü Bu, who pierced Guo Si with his lance. Guo Si's men came forth, saving their general, and both sides withdrew.[35] Another instance of individual combat occurred between Taishi Ci, then serving under Liu Yao, and Sun Ce. Taishi Ci was on a mission accompanied by only a single horseman when he met Sun Ce, who had 13 other men with him. Taishi Ci charged at Sun Ce and the two sides clashed in single combat. Sun Ce pierced Taishi's horse and managed to grab hold of his halberd while Taishi removed Sun's helmet. When their respective reinforcements showed up, they disengaged and the duel came to an end.[36]

Combat between generals and officers during battle is also mentioned by the Records. In 197 Yan Xing, an officer of Han Sui, engaged with Ma Chao and nearly killed him when his spear broke and pierced Ma Chao's neck.[37] In 200 Yan Liang, a general of Yuan Shao, was slain by Guan Yu, then serving under Cao Cao, during the Battle of Boma.[38][39] In 214 Zhang Liao charged Sun Quan's army with only 800 men and reportedly killed ten soldiers and two officers. He then broke through the enemy ramparts and challenged Sun Quan to a duel, to which he declined.[40]

Cao Cao

Art of War and was fond of hawking and hunting with dogs. He was also considered a troublemaker and local thug in his town. At one point in his youth, Cao Cao and Yuan Shao raided a wedding. Cao Cao kidnapped the bride and directed the pursuers toward Yuan Shao.[41] Xu Shao foretold that Cao Cao would be "a good servant in time of peace, a dangerous chieftain in time of trouble".[42]

In the 170s Cao Cao became a chief of police in Luoyang and made a name for himself as a strict enforcer of the law. He was eventually implicated and dismissed from his post in 178.[42]

Cao Cao took part in suppressing the

Yellow Turban rebellion in 184 as a Commandant of Cavalry. He was then appointed Chancellor of Jinan Commandery, where he set about removing officials under the influence of the imperial family. Cao Cao became afraid of the enemies he had made at court so he left his post.[42]

In 188 Cao Cao became a colonel of the Western Garden. When

He'nan Commandery only to suffer defeat at the Battle of Xingyang.[43]

Cao Cao raised more troops in

Qing Province, Cao Cao succeeded him. By the end of the year Cao Cao had negotiated the surrender of the rebels, who augmented his army with 30,000 additional soldiers, known collectively as the Qingzhou Troops (青州兵).[43]

In 193 Cao Cao drove away

Xu Province. Cao Cao invaded Xu Province in retaliation massacring hundreds of thousands of civilians on his first campaign, but in 194 while on his second campaign against Tao Qian his former friend Zhang Miao raised the flag of rebellion in Yan Province. With the aid of Lü Bu, the rebels dealt several defeats to Cao Cao, taking most of the province. Eventually the tide turned on them and Cao Cao regained his territories. Zhang Miao's family was destroyed while Lü Bu fled to Xu Province.[43]

In 196 Cao Cao took control of the imperial court and moved it to

Gong Du. With Yuan Shao no longer posing a threat, Cao Cao returned to deal with Liu Bei, driving him away to take refuge with Liu Biao.[44]

In the summer of 202, Yuan Shao died, leaving his territory to his sons. They fought among themselves and fell prey to Cao Cao's advances. By 205 he had ousted

Bing Province under his control. In the summer of 207 Cao Cao made a roundabout trip north and defeated the Wuhuan at the Battle of White Wolf Mountain. They fled to Gongsun Kang in Liaodong Commandery, but he beheaded them and delivered their heads to Cao Cao.[45]

As Cao Cao prepared to campaign south in 208, Liu Biao died. His son Liu Zong surrendered while Liu Bei fled further south. Cao Cao followed and defeated Liu Bei at the

Changjiang, Cao Cao retreated north.[46]

In 211 Cao Cao moved west against

Battle of Tong Pass. In 212 Cao Cao left Xiahou Yuan behind to continue the northwestern campaign while he returned east to attack Sun Quan across the Huai River. The invasion force reached the banks of the Changjiang but failed to break the enemy defenses. Cao Cao returned to Ye City in 213.[46]

In 215 Cao Cao eliminated Zhang Lu and occupied

Fancheng. However he was unable to take the city and was himself killed when Sun Quan's general Lü Meng who took advantage of the situation and attacked him from behind. Cao Cao died soon afterward on 15 March, 220. He was succeeded by his son Cao Pi.[47][citation not found
]

Although primarily known as a military leader, Cao Cao also compiled a commentary on the Art of War and was a renowned poet and player of the game of

weiqi.[46] His two most famous poems, Though the Tortoise Lives Long and Short Song Style were written during and right before the battles of White Wolf Mountain and Red Cliff
.

《龜雖壽》

Though the Tortoise Lives Long

神龜雖壽,猶有竟時。

Though the tortoise blessed with magic powers lives long,
Its days have their allotted span;

騰蛇乘霧,終為土灰。

Though winged serpents ride high on the mist,
They turn to dust and ashes at the last;

老驥伏櫪,志在千里;

An old war-horse may be stabled,
Yet still it longs to gallop a thousand li;

烈士暮年,壯心不已。

And a noble-hearted man though advanced in years
Never abandons his proud aspirations.

盈縮之期,不但在天;

Man's span of life, whether long or short,
Depends not on Heaven alone;

養怡之福,可得永年。

One who eats well and keeps cheerful
Can live to a great old age.

幸甚至哉!歌以咏志。

And so, with joy in my heart,
I hum this song.

Later history

Emperor Wu of Jin (Sima Yan)

There are broadly speaking five possible operations for any army. If you can fight, fight. If you cannot fight, defend. If you cannot defend, flee. The two remaining operations include only surrender and death. If you are not willing to face bondage, then all that is left for you is to die and spare your family of the ransom.[48]

— Sima Yi

On 11 December, 220, Cao Pi deposed the last Han emperor and proclaimed himself Emperor of Cao Wei.[49] During his reign Cao Pi alienated his brothers Cao Zhang and Cao Zhi. Cao Pi deeply distrusted his close kin and reduced their powers out of suspicion of their loyalty. Cao Pi died in 226 and was succeeded by his son Cao Rui. Although Cao Rui was twenty years old, he was nonetheless appointed a regency council by his father prior to his death. By 236, three members of the regency council had died, leaving Sima Yi as the primary leader of Cao Wei. Before this time, Shu Han launch attacks on the Wei borders and in 229, Zhuge Liang occupied Wudu Commandery. He was, however, unable to make any further gains during his battles against Sima Yi and died in 234. [50] In 238 Sima Yi annexed the Gongsun state in the northwest.[51] This was followed by a campaign into Goguryeo in 244 and 245.[51] Cao Rui died in 239 and was succeeded by his adopted son Cao Fang, who fell under the regency of Cao Shuang and Sima Yi.[52]

In 249 Sima Yi killed Cao Shuang and seized power in Wei. He died two years later and was succeeded by his son

Jin dynasty.[53]

Sima Yan went on to annex the southern state of Eastern Wu in 280, putting an end to the period of the Three Kingdoms.[53]

Shu Han

Liu Bei

Shu Han was founded by Liu Bei in 221 and was conquered by Cao Wei in 263.

Liu Bei

Liu Bei was a very distant descendant of Emperor Jing of Han. His father Liu Hong died when he was still very young and his mother made a living by selling straw sandals. In 175 Liu Bei was sent to study at the Taixue of Luoyang, where he became friends with Gongsun Zan. Liu Bei had very little interest in books but had a knack for fighting and inspired many young men to join him. With the support of two merchants, Zhang Shiping and Su Shuang, Liu Bei was able to create a sizable following including his long time friends Guan Yu and Zhang Fei. When the Yellow Turban Rebellion broke out in 184 Liu Bei led his troops against them under various commanders. He did well in both campaigns but was only rewarded with a very low position in the imperial service. He abandoned his post when an officer tried to reduce his position and joined Guanqiu Yi on an expedition against rebels in Danyang Commandery. For his service in that expedition he was rewarded with the post of assistant magistrate in a county in Pingyuan Commandery. When the anti-Dong Zhuo coalition formed, Liu Bei raised troops in their service, but soon afterwards left to join his friend Gongsun Zan in the north.[54]

Liu Bei assisted Gongsun Zan against his rival

Xu Province offered him 4,000 troops and a post in Pei Commandery, Liu Bei accepted. Tao Qian died in 194 and Liu Bei succeeded him as Governor of Xu Province. In 196 Yuan Shu invaded from the south and fought Liu Bei for a month at a stalemate. During this time however, Liu Bei had lost Xiapi Commandery due to Zhang Fei killing its Chancellor allowing Lü Bu, who was at the time taking refuge in the province, to attack Liu Bei and forced him to surrender. Having defeated Liu Bei and taken control of Xu Province, Lü Bu drove away Yuan Shu's army. Though he was defeated, Liu Bei still retained Pei Commandery. When Yuan Shu attacked Liu Bei again, Lü Bu prevented his advance out of fear that Yuan Shu would become too powerful. Liu Bei continued to recruit troops until 198 when he intercepted a trade convoy from Lü Bu. Lü Bu's officers Gao Shun and Zhang Liao retaliated, taking Pei Commandery and forcing Liu Bei to flee to Cao Cao. Cao Cao sent an army under Xiahou Dun to assist Liu Bei against Lü Bu. In the autumn their army was defeated by Gao Shun. When Cao Cao joined them in the winter, they successfully laid siege to Lü Bu in Xiapi Commandery and killed him the following year.[55]

In 199 Liu Bei was sent to intercept Yuan Shu from making contact with Yuan Shao. When Liu Bei reached Xu Province, he rebelled, killing the Inspector

Stationed on the northern frontier of Jing Province, in 202 Liu Bei achieved victory against Xiahou Dun and

Changjiang where they were heavily defeated by Cao Cao at the Battle of Changban in Nan Commandery. While Cao Cao occupied the naval base at Jiangling, Liu Bei retreated to the southeast towards Xiakou, and Zhou Yu, general of Sun Quan to the east, came upriver with a sizable army. Having augmented his main army with Jing Province's fleet, Cao Cao continued his advance in the winter against Zhou Yu and Liu Bei's forces arrayed on the east bank of the Changjiang. Despite his superior numbers, Cao Cao was defeated at the Battle of Red Cliffs and his fleet was destroyed by a deployment of fire ships by Sun Quan's officer, Huang Gai. In the winter of 208-209 Liu Bei has conquered most of southern Jing while Zhou Yu had captured Jiangling thus ending any hope Cao Cao had of obtaining area across the Changjiang.[57]

After

Yi Province as an ally. In 212 Liu Bei betrayed Liu Zhang and attacked him, waging a two-year war that ended in Liu Zhang's surrender and Liu Bei's conquest of Yi Province. In 215 Sun Quan demanded that Liu Bei give him all of southern Jing Province that Liu Bei had obtained. When Liu Bei denied his demands, Sun Quan sent an invasion force commanded by Lü Meng and Lu Su and Liu Bei sent Guan Yu to confront the two in response while he gathers troops for an inevitable battle. A settlement was eventual reached, dividing southern Jing along the Xiang River. In 217 Liu Bei invaded Hanzhong Commandery, which was then under the control of Cao Cao, and solidified his gains in 219 by achieving a decisive victory over the Cao army and killing Xiahou Yuan.[58]

In the autumn of 219, Liu Bei proclaimed himself King of Hanzhong at a coronation ceremony in

Xiangfan, but Cao Cao's cousin Cao Ren held out and Cao Cao's officer Xu Huang came to his rescue and drove Guan Yu away from Fan Castle. In the winter while Guan Yu was fighting against Cao Ren an offensive by Lü Meng into Nan Commandery ruined Guan Yu's position and he was killed by Lu Meng upon his capture. Sun Quan thus had seized all of Jing Province.[59]

On 15 May 221, Liu Bei proclaimed himself emperor. He then attacked Sun Quan through the Three Gorges and into the middle Changjiang. The following year Lu Xun destroyed Liu Bei's line of camps and forced him to retreat to Baidi Castle with heavy losses. Liu Bei fell ill soon after the battle and upon Sun Quan being under attack by the forces of Cao Pi the two reformed their alliance. Liu Bei died in the summer of 223 and was succeeded by his son Liu Shan, though the government was effectively under the control of Zhuge Liang as a part of Liu Bei's dying request.[59]

Sun Zi, who is traditionally credited with the authorship of The Art of War. Whether the claimed ancestry is true or not, Sun Jian's family played little role in the affairs of the Han dynasty, and next to nothing is known about Sun Jian's obscure lineage.[60]

As a youth, Sun Jian was described as unusual in appearance, kind, intelligent, but fond of odd behavior. At the young age of 16 he was appointed a junior civil officer in the county administration. Sun Jian first made a name for himself at the age of 17 when he went on a trip with his father to Qiantang. During the trip they heard of a band of pirates led by Hu Yu robbing nearby travelers. Sun Jian wanted to attack them while his father wanted nothing to do with the pirates. Even so, Sun Jian set out to confront the pirates. He climbed onto a hill overlooking their camp and waved his sword as if directing soldiers to attack. The pirates thought Sun Jian was part of a government force so they fled. Sun Jian chased after them and took one head as proof of his success. Thereafter, he was promoted to Commandant.[61]

In 172, Sun Jian was appointed Major of troops in Wu Commandery to put down

Xu Province
, where he gained a sizable following, and was well liked by those around him:

Wherever Sun Jian went he gained a good reputation, and the officers and people loved him and trusted him. There were always hundreds of his old friends from his home district and young adventurers who came visiting him. Sun Jian looked after them and cared for them like his own family.

During his time there, he came to butt heads with Dong Zhuo, who felt that Sun Jian was a good commander but lacked quality troops.[64]

In 186, Sun Jian returned to the capital and in 187 was promoted to Grand Administrator of

Ou Xing, Zhou Chao, and Guo Shi
, even aiding neighboring commanderies, much to the consternation of his clerical officers:

I have none of the civil graces. Warfare is my work. If I cross the borders to attack some rebels, that is simply giving help to a neighbour. Even if I am committing a crime, why should I feel ashamed?

Sanguo Zhi

For his service in defeating the rebels, Sun Jian was enfeoffed as Marquis of Wucheng, the highest noble rank attainable for a man outside of the imperial family.[66]

When

Jing Province, he killed its Inspector Wang Rui as well as the Administrator of Nanyang Commandery, Zhang Zhi, and took over their troops. Sun Jian took the lead in the allied offensive but was defeated by Xu Rong in 191. After recovering from his losses, Sun Jian defeated Hu Zhen and captured the capital of Luoyang. Defending the devastated city however was unfeasible, so he retreated with the Imperial Seal in tow, and passed it down to Yuan Shu. While Sun Jian was attacking Luoyang, the alliance had already broken up, and Yuan Shao's general Zhou Yu (Renming) attacked his base camp. Sun Jian returned and drove back Zhou Yu's army. Yuan Shu then sent him against Liu Biao in Jing Province, where Sun Jian died at the age of 37 in a skirmish near Xiangyang.[67]

Together we raised loyal troops, intending to bring aid to the nation. The rebels and bandits are on the point of destruction, and yet people can act like this. Whom can I work with?

Sun Ce

Sun Ce was still young, and though he had his rank and was now well known, all the soldiers and people called him "Young Gentleman Sun." When men heard that Young Gentleman Sun was coming, they quite lost spirit, and the local magistrates and other officials would abandon the cities and run away to hide in the hills and open country. Then he would arrive, and the men of his command respected order, and they did not dare to rob or plunder: not even chickens or dogs or vegetables were stolen. And so the people were extremely pleased, and they would all come to bring cattle and wine as a welcome to the army.
