Chinese Military History II

Weapons and Military Technology

China has been an “advanced” country, in comparison to its contemporaries, through most of recorded history, losing ground only after the Industrial Revolution began in Britain. The major innovations in weaponry that influenced Western military history have their counterparts in China. Any list would include the crossbow, armor, the stirrup, fortifications, gunpowder weapons, and shipbuilding.

In the Qin and Han conscript armies, infantry and cavalry replaced chariots as the principal arm, and the infantry were armed with spears, bows, and in particular crossbows (nu), a weapon in whose technology the Chinese remained superior. Later descriptions of Chinese armies usually include units of archers mixed with crossbowmen, the latter presumably needing protection between rounds due to their longer reloading time. The intricate trigger latch mechanism of the crossbow was a closely guarded state secret under the Han. Battle accounts (too often, unfortunately, influenced by literary conventions) often mention the sky being darkened by clouds of arrows. Evidence for the actual conduct of battles is sketchy, but discharges of arrows (including crossbow bolts) were crucial to victory. Even though infantry bearing shields, swords, and spears existed, there is no trace of either a “phalanx” or a “legion” style of infantry fighting.

Qin Shi Huangdi’s tomb army is wearing armor, and there are many later representations of armored Chinese soldiers. Most of the armor is of the lamellar variety, in which overlapping leather or metal plates of varying size are laced together. Such armor is relatively light and flexible at the expense of protective strength, and in the West infantry and cavalry trained for shock tactics and reliance on edged weapons tended to move on to armor composed at least partly of large plates, of which there are a few Chinese examples.

The idea that the stirrup, by permitting the evolution of shock cavalry armed with the lance, was a primary factor in the creation of European feudalism has received a surprising degree of credence, though recent reevalution of the four-horned Roman saddle has undermined its central thesis. In China the spread of the stirrup is associated with the development of the armored cavalryman, mounted on an armored (barded) horse and armed with a lance. Literary references to “armored cavalry” occur as late as the Tang, and a vivid pictorial representation of mounted warriors looking like European knights occurs in a tomb dated to 357 c.E. Nevertheless, it may be stated with confidence that the social outcomes attributed to the stirrup in Europe did not occur in China. Knight-like cavalry were part of the ruling class of north China during the Northern and Southern Dynasties period. This class, which evolved into the governing aristocracy of the Sui and Tang, was largely Xianbi in origin but also included other Inner Asian peoples and Chinese who had adopted barbarian ways. Far from devolving into feudalism, the Sui and Tang dynasties erected a powerful and enduring version of the centralized, bureaucratic empire previously built by the Qin and Han. And, stirrupped or not, the cavalry future belonged to the Inner Asian warrior whose strength was his skill with the bow rather than the lance.

China has always been a country of cities rather than castles, and city walls were not only a means of defense but also a symbol of the city’s status in the hierarchy of rule. The walls were formidable defenses. While there are many recorded examples of long sieges and much literature on siege-craft, it remained the case that the best way to take a city was by treachery or surprise during a period of confusion, and a siege was more likely to be won by protracted blockade than by a successful assault. China’s urban fortifications did not evolve the low, relatively cannon-proof bastions of the trace italienne, as European cities did in the sixteenth century while China lived peacefully under the rule of the Ming. Afterward, the thick earthen walls of the major Chinese cities remained highly resistant to the gunpowder weapons that were becoming more prominent in Chinese warfare.

The basic formula for gunpowder was known to the Song, weapons incorporating gunpowder were used prominently during the Yuan, and in the Ming Yongle reign (1402-1424) a special headquarters was established in Beijing to coordinate the training of gunners. Firearms added to the defensive strength of the Great Wall, itself a Ming creation, and the Chinese element of the Manchu banner system seem to have been valued, in part, as artillery specialists. However, we cannot discern a “gunpowder revolution” in Chinese military history. In the Ming, Qi Jiguang’s successful and widely emulated military organization had gunners serving alongside bowmen, swordsmen, and spearmen in the same primary (squad-level) formations, and in the Qing Zeng Guofan’s Hunan Army battalions combined newer and older weapons in the same way. Firearms originated in China, but in China they remained just another missile weapon. One does not see efforts to standardize manufacture, reduce the number of calibers, or create new tactics and organizations to exploit the potential of a new weapons system.

Marco Polo’s descriptions of Chinese ships were part of his credibility problem in Europe, and Europeans also found it difficult to credit the early Ming naval voyages. It is now accepted that China built wooden ships as large or larger than any ever built in Europe, and, having invented the compass, navigated them beyond the sight of land to Africa and other distant coasts. But these capabilities did not add up to a navy; in the latter part of the Ming and in the Qing, China’s seagoing forces consisted of small ships and boats tethered to the military organizations of specific provinces.

China’s long history of technological progress provides scant comfort for theories that see certain kinds of social and political change as the inevitable result of specific technologies. Neither the stirrup nor gunpowder had the dramatic consequences in China claimed for them in Europe. With respect to shipbuilding technology, Ming China’s withdrawal from the sea was deliberate and dramatic, and had long-lasting consequences. It compares to Tokugawa Japan’s “giving up the gun.” In both cases, ruling establishments feared and prevented technology-driven change.

Military Institutions

Within the context of the factors of continuity and change already discussed, we may see three broad (and partly overlapping) subperiods in the evolution of Imperial China’s military institutions and practices, each of which transcends any single dynasty, and each of which came to an end due to a crisis of Chinese civilization involving the two basic military threats: domestic rebellion and foreign invasion. The first subperiod is bounded by the rise of Qin in the Warring States and the end of the last of the Six Dynasties in 589 C.E., the second by the consolidation of the Northern Wei in the fifth century and the final Mongol conquest of the Song in 1279, and the third by the Kitan conquest of part of north China in the tenth century and the fall of the imperial system as a whole in the twentieth century. We will label these subperiods Han, Tang, and Mongol-Manchu.

Western Han Dynasty (206 BC–AD 9)


The two Han dynasties continued to employ the cadre-conscript army developed by the state of Qin during the Warring States, just as they continued the bureaucratic system and other Qin institutions. Similarly, the military systems of the Three Kingdoms, the ephemeral Western Jin (265-316), and the later south China regimes collectively called the Six Dynasties evolved from the Later Han state of affairs in which rival warlords controlled armies of dependent soldiers (buqu).

The career and reforms of Shang Yang (d. 338 B.C.E.) in Qin are described in a hostile and caricatured way in the sources, but they converted Qin permanently into the strongest of the seven warring states well over a century before the final Qin conquest of China. Shang Yang abolished hereditary status and created a new set of “titles of nobility” (jue) that could be conferred on any male subject, but only for success in war or agriculture. The population was organized in mutual responsibility groups and governed by officials who could not be natives of the areas they governed. These officials were rewarded (or punished) strictly for their success (or failure) in carrying out their orders. The other states contemporary with Qin undertook less comprehensive and less successful reforms, but Qin retained the leadership that Shang Yang’s reforms had conferred. Qin’s greatest general, Bai Qi (d. 257 B.C.E.), made it a deliberate policy to massacre the armies of the states he defeated in order to maintain Qin’s comparative advantage.

While the first Han emperor made a great show of moderating the severity of Qin laws and experimented with a limited revival of feudalism, in the end the Han continued most Qin institutions, including the Qin military system. For most people conscription was the most important element of that system. Men were drafted for two years, serving as infantry, cavalry, or sailors according to their background. For a small minority this meant service in the capital, and for a larger minority service along the walled defenses of the northern frontier, whose operation in Han times is understood in unusual detail from surviving contemporary documents. Most conscripts seem to have served their time within their native province (jun, “commandery”), whose governor (taishou, literally “grand defender”) was also their commander in case of invasion. The founding of the Han coincided closely with the unification of the Xiongnu under Maodun, and Han Wudi’s resort to war against the Xiongnu is associated with the creation of specialist cavalry forces that could fight in the Xiongnu manner, most famously by Huo Qubing (d. 117 B.C.E.). But Wudi’s wars against the Xiongnu and his annexations of territory in Korea, south China, and Vietnam were made possible by the mobilization of large numbers of mostly infantry troops, and this capacity was retained under his successors.

Guangwudi (r. 25-57), the founding emperor of the Later Han, lightened the military burden by eliminating the annual summer mobilization of the reservists. The Later Han maintained military pressure on the Xiongnu, and finally broke them up for good. Except for the adventures of Ban Chao (d. 102) in the Western Regions (now Xinjiang), which were a classic example of indirect rule maintained by locally recruited troops, the Later Han was not committed to territorial expansion. Despite coups and conflicts in Luoyang, relative peace prevailed in the provinces, along with increasing concentration of landownership. When the Later Han confronted its major military crisis, the Yellow Turban rebellion (from 184), the fastest way to mobilize large armies was to recruit among the dependent clients of already powerful notables; a breakdown to war-lordism followed quickly.

Cao Cao (155-220) was the most successful of these warlords, and his descendants were the rulers of Wei, the most powerful of the Three Kingdoms. His rivals founded Shu-Han (221-263, in Sichuan) and Wu (formally 229-280, at Nanjing). The Jin dynasty of Sima Yi and his descendants ended the Three Kingdoms and briefly ruled over a reunified China. After the rebellions and invasions of the early fourth century, the Jin ruled south China from Nanjing until 420, where four more Chinese dynasties followed until 589.

Many scholars believe that under these dynasties peasants were reduced to the status of serfs, and that armies also were composed of soldiers who were unfree dependents (buqu). While some of this theorizing is in the service of a Marxist periodization of Chinese history, it is very clear from the histories of these dynasties that a warlord pattern had developed: For whatever reason, soldiers were at the disposal of their generals, and central authority was correspondingly fragile. While expressions of disdain for soldiers can be found in the literature of the period, many eminent literary figures also exercised high military command, and the warlord founders of two dynasties (Liu-Song and Liang) had sons who compiled major literary collections (Liu Yiqing and Xiao Tong, compilers of the Shishuo xinyu and the Wenx-uan, respectively). The Sui conquest of Nanjing ended this line of evolution.

Tang Dynasty (618–907)


In 493 Tuoba Hong, the Northern Wei emperor posthumously titled Xiaowendi, played a trick on his Xianbi clan leaders. Pretending to lead them in an invasion of south China, he instead made them stop at the still impressive ruins of Luoyang, the capital of the Later Han and Western Jin, which he made his own capital. North China had been overrun early in the fourth century by various Inner Asian peoples who displayed an uncharacteristic hostility to Chinese civilization. After the disorders of this period, the brief stabilization of the Northern Wei in the fifth century as the first of the important “dynasties of conquest” begins the second period of military evolution. The Northern Wei created early forms of the equal field (juntian) land system and the fubing military system that became major institutions under the Sui and Tang dynasties. Most important, the Northern Wei attempted to create a society in which the military skills of the Xianbi would be complemented by bureaucratic and literary skills of the Chinese educated elite. Later dynasties of conquest made the same attempt, and in military matters Inner Asian influence was important even in dynasties (Sui, Tang, Ming) usually considered Chinese.

After the breakup of the Northern Wei, Yuwen Tai (505-556) and his descendants ruled the northwest first through puppet emperors of Western Wei and then as emperors of the Northern Zhou, and there both the soldier-farmer (fubing) military system and the mixed Chinese and Inner Asian Guanzhong aristocracy that commanded it evolved to provide military means and leaderhip for the Sui and Tang empires. The Yuwen rulers were not of Chinese origin, while the Sui founder and the father of the Tang founder were married to sisters from the Xiongnu Dugu clan. By the end of the sixth century, surnames within the Guanzhong aristocracy did not indicate purely Chinese or Inner Asian ancestry because of intermarriage, and similarly the fubing soldiers included elements capable of fighting on foot or on horseback. Under the fubing system each headquarters (fu) commanded about one thousand farmer-soldiers who could be mobilized for war. In peacetime they were self-sustaining on their land allotments, and were obliged to do tours of active duty in the capital. These tours were usually one month long (two months for the most distant units), and their frequency depended on the distance of each unit from the capital. The fubing soldiers permitted the Sui and Tang founders to conquer China, but attempts at foreign conquest were less consistently successful. Obsessive efforts to subdue the Korean kingdom of Koguryo ultimately cost the second Sui emperor his throne and his life. Tang Taizong (r. 626-649) fought both Türks and Tibetans to peace on favorable terms, but failed to overcome Koguryo. That goal was accomplished by his son Gaozong (r. 649-683), though the final winner was not Tang China but its ally, the southern Korean kingdom of Silla, which succeeded in unifying the entire peninsula under its own rule. Japan, which had supported Paekche, the third Korean kingdom, was alarmed by these developments and responded by imitating the fubing and other Tang institutions in the Taika reforms.

Most of the fubing units were located in the northwest, and the system was best suited for the annual campaigning cycle of an expanding empire. Under Empress Wu (r. 684-705) the fubing system declined, and under Xuanzong (r. 712-756) a standing army stationed on the northern frontier evolved in its place. This army reached a strength of half a million men and eighty thousand horses by the 740s. Its Chinese personnel included many men displaced by economic changes since the founding of the Tang, and its non-Chinese personnel included Koreans, Kitan, Türks, and Sogdians. The new standing army thus preserved the Chinese-Inner Asian mixture characteristic of the early Tang, but the old Guanzhong aristocracy ceased to have much involvement with it and its higher ranks came to be filled from within. Having accepted the decline to uselessness of the fubing system, the Tang court had no central army to resist the An Lushan rebellion, and could only counter it by appealing to other frontier commanders whose social background was similar to An Lushan’s and who could move swiftly from loyalty to rebellion when their autonomy was challenged. Despite impressive successes by the court, the pattern of regional warlordism continued until the fall of Tang. While the replacement of the fubing system with the standing army was a major discontinuity in China’s military development, this discontinuity occurred in a period of peace as a result of a deliberate policy decision of the Tang government. While it led to disorder, it was not caused by defeat.

Recognizing the need for a central army as a counterweight to the troops of the regional warlords, the post-An Lushan Tang emperors created the Divine Strategy (Shence) Armies, whose eunuch commanders grew increasingly powerful as the Tang declined. The Privy Council or Bureau of Military Affairs (Shumiyuan), originally a eunuch agency, was taken over by generals during the Five Dynasties (907-960), while continuing to command the central armies (jinjun, qinjun) at the personal disposal of the emperors. The Five Dynasties were politically unstable, each ending in a violent overthrow, but they were militarily successful, since the territory ruled from Luoyang expanded and the troops were increasingly concentrated in the central armies.

The Song founder continued this system, making modifications in the interest of political stability. He retired his principal generals, turned the Bureau of Military Affairs into a department controlled by civil officials, and moved the capital to Kaifeng to make supply via the Grand Canal easier. The chain of command over the central army troops concentrated in the capital area was changed regularly to prevent any general from developing a dangerous personal ascendancy over a particular body of troops. Under the first three Song emperors, the army was efficient enough to reunify the south Chinese states (the Ten Kingdoms) with the empire, but was not strong enough to destroy the two states ruled by Inner Asian peoples (Tangut Xixia and Kitan Liao) that together dominated the northern frontier. The long-term trend in the Northern Song was for the central army to become larger and more expensive, while its soldiers became poorer and less capable militarily and its civilian administrators more intrusive and abusive. The relative ease with which the Jurchen Jin conquered Kaifeng and the rest of north China illustrated the decay to the Song military system. The Hangzhou-based Southern Song depended militarily on an exiguous combination of warlord-led improvised armies and naval power (exercised along the Yangzi as well as on the ocean). The execution of Yue Fei, the most prominent of the warlords, restored political stability even as it dimmed the hope of reconquering the north. When the Mongols completed the destruction of the Southern Song in the 1270s, they ended both the much-discussed “early modern” economic developments of the Song and the continuous line of military evolution that had begun in the Northern Wei.

Ming Dynasty (1368~1644)


While the Mongol conquest of the Song might be seen as the beginning of the third period of evolution, in fact the Mongols derived both ideas and personnel from their Kitan and Jurchen predecessors in the conquest of north China. Both of these dynasties organized their tribal populations into military units that were also social organizations, and employed the decimal system as the partial basis for this organization (in the Jin meng’an-mouke system, the meng’an is an obvious cognate for the Mongolian mingghan, or “thousand”). Both dynasties also assigned troops to princely appanages (ordo, whence the English “horde”), and made these a vital part of their military systems. In general the Kitans welcomed Mongol rule, and many Jurchens came to accept it; both nations collaborated in the further Mongol conquest of China.

After his elevation in 1206 but before his invasions of north China, Chinggis (Genghis) Khan organized his Mongolian population on a tribal military basis. Every warrior, with his family and possessions, was assigned to a particular unit and forbidden to leave it on pain of death. Both the military obligation and the specific rank within the unit were hereditary. The units were decimal: tumen (ten thousand), mingghan, jaghun (hundred), and arban (ten). The Mongols also imposed this system of decimal organization and hereditary obligation and status on their Chinese soldiers.

The succeeding Ming dynasty (1368-1644) originated in rebellion against the Mongols, but they derived their own soldier-farmer (weisuo) system from the Mongol model, even though they compared it explicitly to the Tang fubing system. Hereditary military personnel were assigned military colony lands to cultivate under the direction of hereditary military officers, and armies for active service were mobilized from this pool of theoretically ready personnel. In a process somewhat resembling the history of the Tang military, the Ming weisuo system also evolved into a recruiting agency for a standing army based on the northern frontier, whose military efficacy was based on the spread of firearms technology and, later, on the building of the Great Wall.

In the early seventeenth century Nurhachi and his successor organized the Manchu—formerly Jurchen—people into a military system, the Eight Banners, that had Inner Asian roots traceable to the Mongols and their predecessors, but was also influenced by Ming institutions of direct rule over Jurchen tributary people. The main theme continued to be hereditary enrollment in specific units. Before the Manchus conquered China proper, they organized some conquered Chinese and Mongols into the Chinese and Mongol Eight Banners. As with the Yuan dynasty’s military forces at their height, the banner forces combined Inner Asian cavalry skills with Chinese abilities in engineering and firearms to create a military power that neither a purely Inner Asian nor a purely Chinese society could resist.

The Manchu conquest of China was aided by the defection of Ming armies, elements of which the Manchus organized into their Green Standard Army (liiying), the other half of the Manchu military system. The military ranks and other terminology of the Green Standard forces can mostly be traced to the standing army of the middle and late Ming. Eventually outnumbering the banner forces, the Green Standard troops played an important part in the Qing conquest of south China. Thay also provided the personnel for Qing naval forces, whose signal success was the conquest and incorporation of Taiwan in 1683. As the Qianlong reign (1736-1795) ended, the variety of military forces at the disposal of the Qing dynasty, all of which were derived by various paths from the Yuan, seemed to have answered conclusively all of the military challenges posed by the history of Imperial China. Internal order was secure. The nomadic threat had been ended by the conquest and inclusion within the Qing empire of Mongolia, Tibet, and Xinjiang. And the annexation of Taiwan had deprived seagoing pirates and smugglers of their main base off the Chinese coast.
