1. The road to Red Cliffs

The Battle of Red Cliffs is the hinge on which the entire political history of late Han China turns. The story of how a single campaign, fought in a few weeks across the winter of 208 and 209 CE, was able to overturn the apparent unification of the empire under the northern warlord Cao Cao, and how a fragile coalition of southern leaders was able to inflict a defeat so decisive that it defined the political geography of China for the next ninety years, requires attention both to the immediate context and to the longer arc of Han decline.

Cao Cao had spent two decades accumulating power. From his first commission under the eunuch court of Emperor Ling in the 170s, through the catastrophe of the Yellow Turban Rebellion and the subsequent revolt of the eunuchs themselves in 189, through the coalition against the eastern tyrant Dong Zhuo in 190 and 191, Cao Cao had positioned himself, with a combination of administrative skill, tactical flexibility, and an instinct for political timing, as the leading warlord of northern China. By 207 he had secured the western front against the Wuhuan of the northern steppe at the Battle of White Wolf Mountain, and by the summer of 208 he had completed the conquest of the four northern provinces that had been the base of the late Han dynasty. He returned to Ye, the old Wei provincial capital, and accepted the formal title of Imperial Chancellor.

The pretext for the southern campaign was the elimination of the southern warlords who had refused to submit. Liu Biao, the governor of Jing Province, had accepted a nominal alliance with Cao Cao but had resisted military occupation. South of the Yangzi, the brothers Sun Ce and Sun Quan had consolidated the Jiangdong region through a series of military campaigns in the 190s and 200s. Between them, these southern warlords blocked Cao Cao’s access to the productive rice lands of the lower Yangzi valley and to the wealthy gentry families who had migrated south in the previous decade.

The immediate cause of the southern campaign was the death of Liu Biao in the autumn of 208 and the succession of his younger son, Liu Cong, against the claims of his elder brother, Liu Qi. Liu Qi had already been sent south to take command of a buffer zone between his father’s base of Xiangyang and the southern warlords of Jiangdong. Liu Cong, who had been left at the provincial capital of Xiangyang, accepted Cao Cao’s offer of a marriage alliance and surrendered the city without a fight. The surrender of Xiangyang gave Cao Cao a forward base in the middle Yangzi and forced the southern alliance to react.

The southern alliance was at first extremely fragile. Liu Bei, whose family had been in the imperial clan of the Han and who had been a sometime ally of Cao Cao, a sometime rebel against him, and a sometime client of the late Liu Biao, had been in Jing Province under Liu Biao’s protection for almost a decade. When Liu Cong surrendered, Liu Bei was forced to evacuate south, with what was left of his army and the population of several tens of thousands of followers who had attached themselves to his cause. Sun Quan, the younger of the two Sun brothers and now the leading power of Jiangdong after the death of Sun Ce in 188, faced the prospect of being the last significant warlord standing between Cao Cao and the unification of the empire.

The classic account, in Chen Shou’s Records of the Three Kingdoms, describes the events of the summer and autumn of 208 through a series of embassies. Zhuge Liang, the future chancellor of Shu, was sent by Liu Bei to Sun Quan as an envoy; Lu Su, Sun Quan’s leading strategist, travelled north to meet Liu Bei; the two sides met at the fortress of Fankou and agreed to a joint strategy. Cao Cao meanwhile marched south along the Xiang River, captured Xiangyang without resistance, and pushed his forward units across the Yangzi into the south bank. The southern alliance withdrew to the area south of the Yangzi, near the present-day border of Hubei and Hunan provinces, where the Yangzi is wide and the southern shore commands the river.

The first phase of the campaign had therefore been entirely in Cao Cao’s favour. He had secured Jing Province without a fight, had forced the southern alliance to retreat across the Yangzi, and had assembled in the Jiangling area a fleet of more than a thousand warships, many of them lashed together to provide stability for his soldiers who were unused to life on the water. By the late autumn of 208, the balance of forces appeared so heavily in Cao Cao’s favour that several commentators recorded that Cao Cao sent a letter to Sun Quan inviting him to surrender in terms that assumed the campaign was already over.

2. The opposing forces

The numerical strength of the armies on each side is one of the most debated questions in the historiography of the period. The traditional figures, reported by Chen Shou and amplified by later commentators, are that Cao Cao brought an army of more than 200,000 to the campaign, while the southern alliance fielded between 30,000 and 50,000. Modern historians regard the figure for Cao Cao as significantly inflated; it includes the population of Jing Province who were conscripted into service after Liu Cong’s surrender and who were largely ineffective in combat. The figure for the southern alliance is more defensible but is also subject to uncertainty.

What is clear is that Cao Cao’s army had two principal weaknesses. First, the men were largely unaccustomed to naval warfare. The Yangzi in the relevant section is a wide, fast, and treacherous river, and the use of large flat-bottomed craft lashed together was a way of stabilising the troops rather than of producing an effective fleet. Second, the army had marched hard and fast from Ye to Xiangyang, with a long logistical tail, and many of the troops were suffering from disease, malnutrition, and exhaustion by the time they reached the Yangzi.

The southern alliance was smaller but had several advantages. The soldiers of Jiangdong, descended from the military households settled by Sun Ce in the previous decade, were experienced sailors. The combined force under Zhou Yu, the commander of Sun Quan’s army, included several thousand marines from the Lake Taihu region of the lower Yangzi who were accustomed to fast and manoeuvrable river craft. Liu Bei contributed a smaller but battle-tested force that had been with him in the long retreat from Xiangyang and that retained its cohesion. The southern force was also supplied through friendly territory, while Cao Cao was at the end of a long and increasingly strained supply line from the north.

The weapons of the campaign were those of the late Han army as it had been developed over the previous century. Crossbows were the dominant missile weapon, with the repeating crossbow invented by Zhuge Liang’s predecessor in the late second century already in use among the southern forces. Spears, halberds, and short swords were the principal close-combat arms. Armour was generally leather or lacquered leather for infantry, with iron scale armour reserved for the more heavily equipped units. Cavalry, which had been the deciding arm of the northern campaigns, was largely irrelevant in a naval engagement fought on the Yangzi.

The leadership on each side is one of the better documented aspects of the campaign. On the northern side, Cao Cao himself was the supreme commander, with his old subordinate Xiahou Dun commanding the land forces and Cao Chun commanding the cavalry reserve. The naval command was entrusted to Cao Ren, Cao Cao’s cousin, who had served with him since the early campaigns. On the southern side, the alliance was commanded on the field by Zhou Yu, with the political leadership of Sun Quan and Liu Bei. Zhuge Liang served as a civilian adviser on the Liu Bei side, while Lu Su and Zhuge Jin represented the Sun family at the political level.

3. The course of the battle

The battle itself was fought in two distinct phases. The first was a preliminary engagement in the late autumn of 208, in which Zhou Yu’s southern force, after a period of cautious manoeuvre along the southern bank of the Yangzi, launched a small probing attack against the northern fleet near the mouth of the Han River. The attack was inconclusive in itself but demonstrated that the southern force was willing to fight and was technically superior in naval manoeuvre. The second phase was the decisive engagement of late December 208 or January 209, traditionally identified with the area around the modern city of Chibi in southeastern Hubei.

The tactic by which Zhou Yu and his colleagues won the decisive engagement has been the subject of commentary since the fifth century. The traditional account, recorded in Pei Songzhi’s commentary to the Records of the Three Kingdoms, holds that Zhou Yu’s chief adviser Huang Gai offered to lead a strike force of several dozen fast boats, filled with incendiary material, against the northern fleet. The plan was for these boats to approach the northern fleet under cover of a feigned defection, and then to set the lashed-together ships on fire. Cao Cao’s fleet, unable to separate in time, was overwhelmed by the resulting conflagration. The southern force followed up with a coordinated attack and routed the northern army, which retreated northwards through Jiangling in disorder.

Recent historical scholarship has been more cautious about the specifics of the engagement. The size of the southern strike force, the nature of the incendiary material, and the exact sequence of events are all debatable. What is not debatable is the outcome: Cao Cao’s fleet was destroyed, his army retreated north across the Yangzi, and the southern alliance retained control of the south bank. The campaign that had begun with the surrender of Xiangyang ended with the destruction of Cao Cao’s southern expeditionary force and the abandonment of any immediate plan to conquer the south.

The political consequences of the defeat were felt almost immediately. Liu Bei, taking advantage of the southern alliance’s victory, marched south into the four southern commanderies of Jing Province and established himself as the de facto ruler of that region. Sun Quan, having committed to a war he had feared his father Sun Ce would not have started, retained control of Jiangdong and the lower Yangzi. Cao Cao returned to Ye, where he spent the next several years consolidating his control of the north and preparing for further campaigns that never quite produced the decisive victory he had hoped for.

4. The historiographical tradition

The Battle of Red Cliffs has the rare distinction of being one of the few battles in Chinese history that has been described in detail by a series of major historians writing in different centuries and from different ideological positions. The earliest surviving account is in Chen Shou’s Records of the Three Kingdoms, completed in the third century CE. Chen Shou was a former subject of Liu Bei’s state of Shu and wrote with a sympathetic view of the southern alliance, particularly of Zhuge Liang and Liu Bei. The work is therefore partial, but it is also the closest to the events themselves and remains the indispensable primary source.

Pei Songzhi’s commentary to Chen Shou, completed in the fifth century, drew on a much wider range of sources, including some that have since been lost. Pei’s commentary added the detail of the incendiary attack and the specific sequence of events that became canonical in the later tradition. The commentary is, in many ways, the source for the popular and dramatic account of the battle that has been current in Chinese literature ever since.

The Tang and Song commentaries on the campaign introduced a more rhetorical element, with the battle presented as an example of how the weak could overcome the strong through superior strategy and superior virtue. The Song historian Sima Guang, in his Comprehensive Mirror for Aid in Government, presented the campaign as a turning point in which the southern alliance’s success was due to the moral clarity of its leaders and to the specific genius of Zhou Yu in command. Sima’s account is more conservative in its treatment of the source material than Pei Songzhi’s, and it is also more didactic.

The Ming and Qing novelists, particularly Luo Guanzhong in Romance of the Three Kingdoms, turned the campaign into the most famous of the period’s set pieces. Luo’s account of the battle, with its long opening dialogues, its detailed depiction of Zhou Yu’s planning, and its emphasis on the heroic rivalry between Zhou Yu and Zhuge Liang, has shaped the popular imagination of the battle in East Asia ever since. Luo’s account is not a reliable source for the actual events; it is a literary reworking of the historical tradition for the purposes of entertainment and moral instruction.

Modern Chinese historiography has been more cautious about the details of the campaign while retaining its central importance. The great twentieth-century historians Chen Yinke, Lu Simian, and Tian Yuqing all devoted attention to the campaign and to the broader military history of the Three Kingdoms period. The current consensus is that the campaign was a turning point, that the southern alliance’s victory was the result of a combination of strategic and tactical factors, and that the immediate consequences of the victory were the consolidation of three separate regional power bases that would compete for the imperial succession until the third century CE.

5. Cultural and literary afterlife

The Battle of Red Cliffs has been the subject of more literary and artistic treatment than any other battle in Chinese history. The combination of great stakes, famous personalities, and a decisive outcome made it irresistible to writers and dramatists, and the campaign has been retold in poetry, prose, fiction, drama, painting, and the visual arts across the entire span of Chinese history.

The poetic tradition begins with the contemporary reaction to the campaign. Cao Cao himself, the great poet of late Han, wrote the famous Short Song Style poems that are traditionally associated with the southern expedition. The poems are melancholy and self-aware, presenting the poet as the man of action who knows that he is past the prime of his life and that the world does not always reward the capable. The poems are also military, with their imagery of the moon, the wind, the river, and the soldiers who do not return.

The Tang and Song poets, looking back on the campaign from a distance, treated the battle as a moment of pure heroism. The great Tang poet Li Bai, in his Early Departure from Baidi City, evokes the campaign as a precedent for his own adventurous journey down the Yangzi: “The kingdom of Wu is far away on the river banks, the banners of Zhou Yu are now dust.” Su Shi, the great Song poet, in his Remembering Red Cliffs, evokes the campaign as an image of the impermanence of human achievement and the indifference of nature.

The Ming dynasty novel Romance of the Three Kingdoms, by Luo Guanzhong, gave the campaign the dramatic shape that has been canonical ever since. Luo’s account of the preliminary diplomacy, of the meeting at Fankou, of Zhou Yu’s strategic brilliance, of Huang Gai’s fire attack, and of Cao Cao’s retreat, is a literary reworking of the historical tradition with the addition of much invented dialogue and incident. The novel is one of the four great classical novels of Chinese literature and has shaped the popular imagination of the Three Kingdoms period across East Asia.

The visual tradition has been equally extensive. The Battle of Red Cliffs was a favourite subject of Chinese painters from the Song dynasty onwards, with the fire attack as the canonical moment. The most famous paintings include Qiu Ying’s Battle of Red Cliffs scroll of the late Ming period, with its detailed depiction of the burning fleet; and a series of Yuan and Qing dynasty depictions that emphasise the heroic leaders and the disastrous outcome for Cao Cao. Modern Chinese painting has continued the tradition, with the campaign frequently depicted in propaganda and popular art.

In East Asian popular culture more broadly, the campaign has been retold in Japanese manga, Korean historical drama, and modern Chinese television series. The most famous of the television adaptations is the 2010 Chinese series Three Kingdoms, in which the Battle of Red Cliffs is the climax of the first season. The campaign also features prominently in the Japanese strategy game Romance of the Three Kingdoms, in which it is one of the playable historical battles.

6. The legacy of the campaign

The Battle of Red Cliffs was the decisive moment in the long civil war at the end of the Han dynasty. The campaign transformed the political map of China in three concrete ways. First, it established the possibility of three regional power bases coexisting on the territory of the late Han empire. The Wei state in the north, the Shu state in the west under Liu Bei, and the Wu state in the east under Sun Quan, all derived their legitimacy from the campaign’s outcome and all defined themselves in opposition to the others.

Second, the campaign produced a permanent realignment of the Chinese political elite. The gentry families who had migrated south in the late Han period had previously looked to the northern capital at Luoyang and at the southern provincial capital at Xiangyang for their political future. The destruction of the northern expedition and the consolidation of the southern power bases meant that the gentry of the lower Yangzi, of the Jiangnan region, and of the southwest became a new political class with their own centres of patronage and their own literary culture.

Third, the campaign established the military and naval institutions that would define Chinese warfare for the next three centuries. The use of fast-moving river fleets, the deployment of incendiary weapons at sea, the integration of naval infantry with land infantry, and the use of the Yangzi as the strategic dividing line of the empire, were all innovations of the campaign and the period of warfare that followed. The Three Kingdoms period is therefore the formative moment in the development of Chinese naval warfare, just as it is the formative moment in the political division of post-Han China.

The campaign has been remembered not only as a military event but also as a moral moment. In the Confucian historiographical tradition, the battle is a story of how the southern alliance, fighting for the legitimacy of the Han line and for the moral principle of resistance to tyranny, was able to defeat the much larger force of Cao Cao, whose ambition was presented as the cause of his downfall. The moral reading of the campaign has been the dominant one in Chinese popular culture for nearly two thousand years, and it remains the principal frame in which the campaign is taught in Chinese schools and universities.

For modern military historians, the Battle of Red Cliffs is also a case study in the conduct of riverine warfare and in the application of asymmetric strategy against an apparently superior opponent. The southern alliance’s success in using terrain, weather, and manoeuvre to offset its numerical inferiority is a classic example of strategic defence against strategic offence, and the campaign has been the subject of sustained study in military academies in China, Japan, and Korea. The campaign is taught as an example of how the moral and political conditions of warfare can be as decisive as the material and numerical conditions, and as an example of how a single decisive engagement can alter the course of an entire century.

7. The campaign in its physical setting

The Yangzi River at the latitude of the campaign runs through a varied geography of cliffs, marshes, and old river courses. The traditional identification of the battle site with the present-day Chibi district in southeastern Hubei, near the city of Xianning, is supported by local tradition, by the placement of memorial monuments, and by the geography of the Yangzi at that latitude, where the river is wide enough to accommodate a fleet of more than 1000 vessels and where the southern bank commands the river through a long ridge of hills. The opposing commanders had a clear field of view from their respective camps and could observe the deployment of their opponents across the river.

The climate of the Yangzi valley at the time of the battle was harsh for soldiers unused to southern conditions. The winter of 208 to 209 was reportedly an unusually cold one, with heavy frost and morning mist that obscured the river for hours at a time. Cao Cao’s northern troops, recruited from the cool dry country of the central plains and accustomed to mounted warfare on open ground, suffered badly from the cold and from the unfamiliar diet of fish and rice. The southern troops of Jiangdong and of the Jiangxia region, in contrast, were acclimatised to the river environment and could move and supply themselves through it with ease.

The Yangzi is also a river of strong currents and sudden changes in depth. The stretch near Chibi includes several channels separated by islands and shoals, and the river flow varies considerably with the season. The southern alliance, operating close to its home territory, could rely on local pilots who knew the river’s behaviour; Cao Cao’s northern force had to rely on captured pilots whose knowledge was partial. The difference in piloting skill was one of the secondary reasons for the outcome of the battle, particularly when the southern fire attack forced the northern fleet into a confused retreat through unfamiliar waters.

The supply situation also favoured the south. The southern alliance was operating within its own territory and could draw on the grain stores of the lower Yangzi and the rice production of the Jiangdong region. Cao Cao’s supply line, running from Ye through Xiangyang and down to the Yangzi, was already long and had been strained by the rapid march of the army in the autumn. The capture of Xiangyang had secured the granaries of Jing Province but had not been sufficient to feed the army indefinitely. The southern commanders’ strategy was therefore implicitly based on the expectation that time and weather would weaken the northern army, even before the open battle was joined.

8. Comparison and reception

The Battle of Red Cliffs is often compared, in the Western historiography of the campaign, with other decisive engagements of similar scale. The Battle of Salamis in 480 BCE, in which a Greek fleet defeated a much larger Persian fleet in the narrow waters of the Aegean, is the closest classical parallel. Both battles involved a numerically inferior coalition facing a numerically superior imperial force; both were decided by superior naval manoeuvre; both had consequences for the political geography of the eastern Mediterranean, in the case of Salamis, and of the Chinese empire, in the case of Red Cliffs.

The comparison is instructive but should not be pressed too far. Salamis was fought in a much narrower stretch of water than Red Cliffs and the Athenian fleet was a genuinely unified force rather than a fragile coalition. The political consequences of Red Cliffs were also longer-lasting than those of Salamis: the Three Kingdoms period lasted ninety years, while the Greek victory at Salamis led to a further century of intermittent warfare against the Persian Empire before the conquests of Alexander. The cultural memory of the two battles is also different; Salamis is a foundational moment in the Greek sense of national identity, while Red Cliffs is one of several turning points in the long narrative of Chinese unification and division.

Western reception of the Battle of Red Cliffs has been, until recently, largely mediated through the Romance of the Three Kingdoms and through the popular imagery of the Three Kingdoms period as a moment of heroic individualism. The popular Japanese computer game Romance of the Three Kingdoms, in which the campaign is one of the playable scenarios, has brought the campaign to a wide international audience. The 2008 film Red Cliff, directed by John Woo, has also been an important recent introduction, with its dramatic recreation of the fire attack and its emphasis on the political rivalry between Zhou Yu and Zhuge Liang. The film was a co-production with mainland Chinese and Taiwanese studios and is one of the most successful Chinese-language films of the twenty-first century.

Scholarly reception in the West has been more cautious. Rafe de Crespigny, the Australian historian of late Han China, has been the most influential modern interpreter of the campaign in English. His Three Kingdoms: A Historical Narrative presents the campaign as a turning point in the long civil war but emphasises the contingency of the outcome and the importance of the political, military, and logistical factors that combined to produce the southern victory. De Crespigny is particularly attentive to the discrepancy between the literary accounts and the historical evidence, and his work is the indispensable starting point for any Western reader who wants to understand the campaign in its historical context.

The campaign’s place in the longer narrative of Chinese unification has been the subject of a parallel historiographical debate. The standard Chinese view, derived from the orthodox tradition of the Romance of the Three Kingdoms, presents the Three Kingdoms period as a tragic intermission in the long history of imperial unification. The alternative view, associated with Chen Yinke and with the modern tradition of regional history, presents the Three Kingdoms period as a moment of legitimate regional autonomy that produced cultural and economic developments that would not have been possible under a centralised empire. The Battle of Red Cliffs, as the moment at which regional autonomy became possible, is therefore a pivot in the larger debate as well as in the immediate military history.

For military historians in East Asia, the campaign has been a touchstone for thinking about the conduct of riverine and naval warfare. The South Korean and Taiwanese naval academies include the campaign in their curricula as an example of how to organise defence against an invasion launched by a larger and better-equipped power. The Japanese Self-Defense Forces, which have a special interest in the lessons of the campaign for the defence of the Japanese archipelago, have included the campaign in their standard training materials. The campaign is, in this respect, one of the few events in Chinese history that has become part of the international professional military curriculum.

For the Chinese historical profession, the campaign has been a long-standing subject of sustained attention. The major works of Chinese Three Kingdoms scholarship, including those of Tian Yuqing, Lu Simian, and more recently Zhang Xiaotao and Zhu Guanzhao, have all devoted detailed attention to the campaign. The current consensus in Chinese scholarship is that the campaign was decisive in establishing the Three Kingdoms period, that the southern alliance’s victory was the result of a combination of strategic and tactical factors, and that the cultural memory of the campaign in the popular tradition has had both positive and negative effects on the modern understanding of the period.
