Nguyễn Huệ

Biography

Family Background and Early Years

Nguyễn Huệ was originally surnamed Hồ and was said to belong to the same clan as Hồ Quý Ly, emperor of Vietnam's Hồ dynasty. His fourth-generation ancestor Hồ Phi Khang had lived in Hưng Nguyên County, Anh Đô Prefecture, Nghệ An, within the northern territory controlled by the Trịnh lords. During fighting between the Trịnh and the Nguyễn lords of Quảng Nam, he was captured by Quảng Nam forces under Nguyễn Phúc Tần and resettled for land reclamation in the Tây Sơn area of Quy Nhơn Prefecture. Because Hồ Phi Khang came from a literate family, Nguyễn lord Nguyễn Phúc Tần appointed him head of the Tây Sơn settlement, an office inherited by his descendants. By the time of Nguyễn Huệ's father Hồ Phi Phúc, the family had moved to Kiên Thành, identified in the Chinese source with present-day Phú Lạc Village in Tuy Viễn County.

Nguyễn Huệ's original name was Hồ Thơm. As a youth he was exposed to ideas that reportedly inspired thoughts of rebellion. His father Hồ Phi Phúc had studied under the Confucian scholar Giáo Hiến. Giáo Hiến was originally surnamed Trương and was the son of the scholar Trương Văn Hạnh. After his father was killed by the powerful former Nguyễn official Trương Phúc Loan, he fled to An Thái and taught both literary and martial subjects. He regarded Nguyễn Nhạc and Nguyễn Huệ as exceptionally talented, valued them highly, and encouraged them to rise against the former Nguyễn regime.

After Hồ Phi Phúc died, Nguyễn Nhạc inherited the position of head of the Tây Sơn settlement and later became a low-ranking tax official at Vân Đồn. Officials under the Quảng Nam Nguyễn lords were then described as deeply corrupt, taxation was heavy, and successive natural disasters helped provoke repeated peasant uprisings. Nguyễn Nhạc seized the tax silver under his control and distributed it to the poor, after which he was wanted by the authorities. He fled with his two younger brothers to the Tây Sơn area, where they became outlaws.

The Tây Sơn Uprising and Alliance with the Trịnh Against the Nguyễn

In 1771, the thirty-second year of the Cảnh Hưng era, Nguyễn Huệ and his elder brothers Nguyễn Nhạc and Nguyễn Lữ established a fortified base in the Tây Sơn area and recruited troops. The Tây Sơn forces denounced the corruption of Trương Phúc Loan and proclaimed the goal of overthrowing him and Nguyễn Phúc Thuần while installing the allegedly capable imperial grandson Nguyễn Phúc Dương as Nguyễn lord. By seizing wealth from the rich and distributing it to the poor, the movement gained broad local support. To gain further support, the three brothers changed their surname to their mother's surname, Nguyễn. They gained the backing of local strongman Nguyễn Thung and wealthy merchant Huyền Khê, absorbed small peasant rebel groups in the surrounding area, and were joined by forces associated with Tập Đình and Lý Tài. Nguyễn Nhạc styled himself First Camp Chief. Nguyễn Huệ was only nineteen but was strong, bold, and known for leading from the front. The Nguyễn-dynasty Biography of the Spurious Tây Sơn later described him as having “a voice like a great bell, eyes flashing like lightning, cunning and skilled in fighting,” so that “everyone feared him.”

In 1774, the thirty-fifth year of the Cảnh Hưng era, Trịnh lord Trịnh Sâm learned of the turmoil in the south and ordered the general Hoàng Ngũ Phúc to lead thirty thousand land and naval troops southward, ostensibly to punish the powerful former Nguyễn official Trương Phúc Loan. Hoàng advanced rapidly and captured Phú Xuân, present-day Huế, the Nguyễn capital, forcing the Nguyễn lord to flee toward Quảng Nam. At the same time, the Tây Sơn forces were moving from Quy Nhơn toward Quảng Nam. Nguyễn Nhạc, Lý Tài, and Tập Đình were defeated by Trịnh forces at Cẩm Sa village, identified with present-day Hòa Vang in Đà Nẵng, and the Trịnh occupied Quảng Nam. Caught between the former Nguyễn forces and the Trịnh, Nguyễn Nhạc made peace with Hoàng Ngũ Phúc and asked to serve as the vanguard against the former Nguyễn.

In 1775, the thirty-sixth year of the Cảnh Hưng era, Nguyễn Nhạc falsely proposed peace to former Nguyễn commander Tống Phước Hiệp. When the latter relaxed his guard, Nguyễn Nhạc ordered Nguyễn Huệ to launch a surprise attack. Nguyễn Huệ defeated the former Nguyễn force and captured Phú Yên. After this victory the Trịnh lord granted him the title “Vanguard General of Tây Sơn.”

Capture of Gia Định and Temporary Destruction of the Former Nguyễn

Although the Trịnh forces had advanced far south, disease soon spread through their army, and Hoàng Ngũ Phúc abandoned Quảng Nam and withdrew to Phú Xuân. The Tây Sơn then occupied Quảng Nam. In 1776, the first year of the Thái Đức era, Nguyễn Nhạc sent Nguyễn Lữ to attack the Gia Định region. Nguyễn Lữ briefly occupied the city but was soon expelled by Đỗ Thanh Nhơn.

In 1777, the thirty-eighth year of the Cảnh Hưng era, Nguyễn Nhạc again sent Nguyễn Lữ and Nguyễn Huệ against Gia Định. The city fell. Nguyễn Phúc Thuần fled to Long Xuyên, in present-day An Giang Province, while Nguyễn Phúc Dương fled to Ba Vát, in present-day Vĩnh Long Province. Both were captured by Nguyễn Huệ's pursuing forces and beheaded together with many members of the royal clan and senior officials. The former Nguyễn ruling group was temporarily destroyed; only Nguyễn Phúc Thuần's nephew Nguyễn Phúc Ánh escaped. The following year, Nguyễn Nhạc proclaimed himself King of Tây Sơn at Vijaya, in the Quy Nhơn area of central Vietnam, adopted the era name Thái Đức, and founded the Tây Sơn dynasty. Nguyễn Huệ received the title Longxiang General.

While Nguyễn Huệ was pursuing the former Nguyễn ruler, Mạc Thiên Tứ, commander of Hà Tiên, accompanied the royal party. After escaping pursuit, he returned to Hà Tiên. The Tây Sơn urged him to surrender, but he remained loyal to the former Nguyễn, refused, and later fled through Phú Quốc to Siam.

Struggle for Gia Định and Defeat of Siam

Although the Tây Sơn had destroyed the main former Nguyễn court, Nguyễn Phúc Ánh remained active. He raised troops in Long Xuyên, and the pro-Nguyễn Đông Sơn forces responded, rapidly recovering Gia Định. With the support of Đỗ Thanh Nhơn and others, the city and its subordinate districts returned to former Nguyễn control. In 1780, the third year of the Thái Đức era, Nguyễn Phúc Ánh executed Đỗ Thanh Nhơn, after which the Đông Sơn forces rebelled and the Gia Định region fell into disorder.

In 1782, the fifth year of the Thái Đức era, Nguyễn Nhạc and Nguyễn Huệ led three thousand land troops and a number of warships south against Gia Định. They fought Nguyễn Phúc Ánh's forces on the Qizhi River. Nguyễn Phúc Ánh received help from the Frenchman Manuel and a European-style ship. The Gia Định Thành Thông Chí describes a major naval battle in which the Tây Sơn used favorable wind and tide to charge directly; Nguyễn forces broke while Manuel's ship continued resisting until Nguyễn Huệ concentrated forces on it, surrounded it, and burned it, killing Manuel. Nguyễn Phúc Ánh withdrew to Phú Quốc. In 1783, the sixth year of the Thái Đức era, Nguyễn Lữ and Nguyễn Huệ again led forces south and decisively defeated Nguyễn Phúc Ánh on the Siqi River, forcing him once more to flee to Phú Quốc.

Nguyễn Phúc Ánh continued his resistance. He sent the French missionary Pigneau de Béhaine with the crown prince Nguyễn Phúc Cảnh to seek help from France and dispatched Chu Văn Tiếp to Siam. In 1784, the seventh year of the Thái Đức era, King Rama I of Siam sent major commanders with twenty thousand troops and three hundred warships into the Gia Định region and ordered another five thousand troops from Cambodia to support them. The Siamese advanced rapidly through places including Rạch Giá, Ba Xắc, Trà Ôn, Bình Triệt, and Sa Đéc. Tây Sơn commander Trương Văn Đa could not stop them and appealed to Quy Nhơn for help. Nguyễn Nhạc therefore sent Nguyễn Huệ to intercept the invasion.

After several engagements with the Siamese, Nguyễn Huệ at one point considered withdrawing and negotiating peace, but former Nguyễn defector Lê Xuân Giác persuaded him not to do so. He instead adopted a strategy of drawing the enemy deep into an ambush. On January 19, 1785, in the twelfth lunar month of the seventh year of the Thái Đức era, Tây Sơn forces prepared an ambush along the banks near Rạch Gầm and Xoài Mút by Mỹ Tho. A small Tây Sơn force lured the Siamese troops stationed at Sa Đéc into pursuit. When they entered the ambush zone, Nguyễn Huệ ordered artillery to open sudden fire on the Siamese warships, then launched land and naval assaults amid the resulting disorder. The Siamese army was decisively defeated, and Tây Sơn forces continued the pursuit of Nguyễn Phúc Ánh. With ammunition and food exhausted, Nguyễn Phúc Ánh escaped to Siam with only a few close followers. This engagement became known as the Battle of Rạch Gầm–Xoài Mút. The source states that afterward the Siamese “feared Tây Sơn as they feared a tiger.”

Northern Campaign Against the Trịnh and the End of the Later Lê Order

After destroying the former Nguyễn government and securing the Gia Định area, Nguyễn Huệ was ordered by Nguyễn Nhạc to campaign north against Phú Xuân, then held by the Trịnh. After occupying Phú Xuân, Trịnh commander Hoàng Ngũ Phúc died, and Trịnh Sâm appointed Bùi Thế Đạt to defend Thuận Hóa, later replacing him with Phạm Ngô Cầu. Phạm was described as timid and suspicious, and the defense of Phú Xuân became lax. Nguyễn Hữu Chỉnh, who was stationed in Thuận Hóa with him, concluded that the Trịnh were doomed and defected to the Tây Sơn.

In May 1786, the ninth year of the Thái Đức era, Nguyễn Nhạc appointed Nguyễn Huệ commander of the expedition, with Vũ Văn Nhậm as commander of the left army and Nguyễn Hữu Chỉnh as commander of the right. Their land and naval forces attacked Thuận Hóa. Nguyễn Huệ sent a fortune-teller to Phạm Ngô Cầu to predict that he would fall ill and to advise him to construct an altar and pray for seven days and nights. Phạm followed the advice and ordered his soldiers to serve at the rites. The Tây Sơn took the opportunity to advance in force. The Trịnh army was defeated, Phạm opened the gates and surrendered, and the Tây Sơn rapidly occupied Thuận Hóa.

After taking Phú Xuân, Nguyễn Huệ pressed on to Đồng Hới and initially intended to hold the old boundary at the Gianh River. Nguyễn Hữu Chỉnh opposed this and urged a further northern campaign against the Trịnh, arguing that the Trịnh generals were lax, the troops arrogant, and the court without discipline, and that if the Tây Sơn claimed to “support the Lê and destroy the Trịnh,” the realm would respond. Nguyễn Huệ eventually accepted the proposal.

The Trịnh regarded Phú Xuân as former Nguyễn territory and initially paid little attention to Nguyễn Huệ's advance, sending only Trịnh Tự Quyền with twenty-seven military units to defend Nghệ An. But as Nguyễn Huệ's forces moved farther north, the defenders of Nghệ An and Thanh Hóa fled without fighting, allowing him to reach the Vị Hoàng River near present-day Nam Định. One night before the battle, he placed wooden figures aboard unmanned boats, beat drums and raised banners, then let the craft drift downstream. Veteran Trịnh commander Đinh Tích Nhưỡng mistook them for an attack and ordered his ships into line to fire their cannon. By the time he realized the boats carried wooden figures, his forces had exhausted their ammunition. Nguyễn Huệ then attacked, forcing Đinh to abandon his ship and flee, while Trịnh Tự Quyền and Đỗ Thế Dận also collapsed.

Nguyễn Huệ continued advancing while proclaiming that his purpose was to “support the Lê and destroy the Trịnh.” Trịnh ruler Trịnh Khải urgently summoned Hoàng Phùng Cơ, defender of Sơn Tây, but Hoàng was defeated at Vạn Xuân Lake, identified in the source with present-day Vạn Phúc commune in Thanh Trì, Hanoi. Trịnh Khải personally took the field on a war elephant but was defeated, captured while fleeing, and committed suicide. Trịnh rule in the north thereby collapsed. Nguyễn Huệ buried him with princely rites and entered the capital Thăng Long to pay court to Emperor Lê Hiển Tông.

After entering Thăng Long, Nguyễn Huệ received the title “Marshal, Supporting the Righteous, Assisting Fortune, Majestic Duke of the State” and married Lê Hiển Tông's youngest daughter, Lê Ngọc Hân. When Nguyễn Nhạc learned that Nguyễn Huệ had independently campaigned against the Trịnh, he sent people to Thuận Hóa to stop him. After hearing that Thăng Long had fallen, Nguyễn Nhạc feared that Nguyễn Huệ might establish himself there and hurried north with troops. He met the Lê emperor and Nguyễn Huệ. Lê Hiển Tông soon died, and Lê Mẫn Đế succeeded him. The new ruler received Nguyễn Nhạc in the former Trịnh residence. Several days later Nguyễn Nhạc invited the Lê ruler and Nguyễn Huệ to the residence, recognized Lê authority in Bắc Hà, and then withdrew south together with Nguyễn Huệ.

Fraternal Conflict and Proclamation as Emperor

In 1787, the tenth year of the Thái Đức era, Nguyễn Nhạc made Nguyễn Huệ “King of Bắc Bình,” based at Phú Xuân. Nguyễn Nhạc styled himself Central Emperor and remained at Quy Nhơn, while Nguyễn Lữ became “King of Đông Định” at Gia Định. Conflict soon erupted between Nguyễn Huệ and Nguyễn Nhạc and escalated into armed fighting.

According to the Biography of the Spurious Tây Sơn, after becoming emperor Nguyễn Nhạc became increasingly violent and indulgent, killed meritorious followers including Nguyễn Thung, and behaved arbitrarily. During the campaign against the Trịnh, treasures from the Trịnh palace had all fallen into Nguyễn Huệ's hands; Nguyễn Nhạc demanded a share but Nguyễn Huệ refused. Nguyễn Huệ in turn wanted Quảng Nam, which Nguyễn Nhạc refused to cede. The source further alleges that Nguyễn Nhạc violated Nguyễn Huệ's wives and concubines, deepening the younger brother's anger. Nguyễn Huệ then issued a proclamation listing Nguyễn Nhạc's crimes and attacked first, surrounding Quy Nhơn. Nguyễn Nhạc summoned Đặng Văn Chân with troops from Gia Định, but Nguyễn Huệ defeated and captured him. Nguyễn Huệ built an earthen mound outside Quy Nhơn, mounted cannon on it, and bombarded the city. Facing defeat, Nguyễn Nhạc reportedly had cannonballs taken to the ancestral temple and wept, then climbed the city wall and asked Nguyễn Huệ, “How can a younger brother bear to cook flesh in a pot made of skin?” Nguyễn Huệ was moved and lifted the siege. The brothers then agreed on a boundary at Bản Tân: territory south of Quảng Nghĩa went to Nguyễn Nhạc, while Thăng Hoa and Điện Bàn and lands to their north went to Nguyễn Huệ, and the two ruled separately.

Meanwhile the political situation in Bắc Hà changed. Soon after Tây Sơn forces withdrew, Trịnh Bồng gathered remnants seeking to restore Trịnh rule and entered Thăng Long, taking control of the Later Lê court. Lê Mẫn Đế urgently recalled Nguyễn Hữu Chỉnh. Nguyễn returned to his home region, raised local troops, and expelled the Trịnh. He then monopolized power himself in a manner compared to the former Trịnh lords. Knowing that Nguyễn Văn Duệ, stationed at Nghệ An, was a subordinate of Nguyễn Nhạc and hostile to Nguyễn Huệ, Nguyễn Hữu Chỉnh attempted to win him over. In 1787 he also sent Trần Công Xán to Phú Xuân requesting the return of Nghệ An to the Later Lê court. Nguyễn Huệ was furious. Following Trần Văn Kỷ's advice, he sent Vũ Văn Nguyệt to escort the envoys home, but their boat was deliberately sunk en route and all aboard drowned. Nguyễn Huệ then sent Vũ Văn Nhậm north, who defeated and captured Nguyễn Hữu Chỉnh. Lê Mẫn Đế fled to Bảo Lộc Mountain. Unable to find the emperor, Vũ Văn Nhậm installed Lê Duy Cận as regent.

In 1788, the first year of the Quang Trung era, Nguyễn Huệ proclaimed himself emperor at Phú Xuân and adopted the era name Quang Trung, becoming the Quang Trung Emperor.

War with the Qing and Qing Investiture

After Nguyễn Huệ proclaimed himself emperor, Lê Mẫn Đế, the last ruler of the Later Lê dynasty, fled into Qing territory and requested Qing military intervention. The Qianlong Emperor ordered Sun Shiyi, governor-general of Liangguang, to lead forces into Vietnam. In 1789, the second year of the Quang Trung era, Nguyễn Huệ marched north, defeated the Qing army near Thăng Long, present-day Hanoi, and recovered the capital. He then changed his name to Nguyễn Quang Bình and sent envoys to seek investiture from the Qing. Recognizing that he held effective control of Vietnam, the Qianlong Emperor invested him as King of Annam.

Later Years and Death

In 1792, the fifth year of the Quang Trung era, Nguyễn Huệ died of illness while preparing to destroy the remaining former Nguyễn forces. After his death, factional conflict between the Tây Sơn groups severely weakened the dynasty. It was destroyed in 1802 by Nguyễn Phúc Ánh, and Nguyễn Huệ's remains were exhumed and subjected to posthumous punishment.

Nguyễn Huệ came of the Tây Sơn Nguyễn. As a youth he was stirred by ideas that bred thoughts of rebellion. His father Hồ Phi Phúc had studied under the scholar Tiêu Hiến, originally surnamed Trương, grandson of the scholar Trương Văn Hạnh, who had been destroyed by a powerful minister of the old Nguyễn — a lineage and a grudge that from the first gave the Tây Sơn brothers their anti-Nguyễn cast. The three brothers won the support of the local magnate Nguyễn Trang and the rich merchant Huyền Khê, absorbed small peasant risings around them and drew risings by Tập Đình and Lý Tài to their side, growing steadily stronger. Nguyễn Nhạc styled himself first chieftain, with Nguyễn Trang second and Huyền Khê third. Caught between the old Nguyễn and the Trịnh, Nguyễn Nhạc made peace with the Trịnh and offered himself as their vanguard against the Nguyễn, while pretending to seek a pact with the Nguyễn against the Trịnh and giving his daughter Thọ Xuân to Nguyễn Phúc Dương, heir of the old Nguyễn. When Tống Phúc Hợp was off guard, Nguyễn Nhạc had Nguyễn Huệ attack; Nguyễn Huệ beat the old Nguyễn army and took Phú Yên, and was made "vanguard general of the Tây Sơn" by the Trịnh lord.

The wars with the old Nguyễn and with Siam formed the main line of Nguyễn Huệ's military career. In 1776 Nguyễn Nhạc sent their brother Nguyễn Lữ against Gia Định, which he took and as quickly lost; Nguyễn Phúc Ánh rose at Long Xuyên, joined by the Đông Sơn army and by Lê Văn Quân, Nguyễn Văn Hoằng, Tống Phúc Khuông and Tống Phúc Lương, and with Đỗ Thanh Nhân's support Gia Định and its dependent districts were recovered for the old Nguyễn. In 1782 Nguyễn Nhạc and Nguyễn Huệ came south with three thousand sailors and soldiers and a fleet, and fought Nguyễn Phúc Ánh's forces at the Seven Channels, where Phúc Ánh had the French adventurer Mạn Hòe with Western ships. By the account in the dynastic history, Nguyễn Huệ's men ran before wind and tide with full sail, Phúc Ánh's fleet broke without fighting, and only the Western ship of Mạn Hòe resisted long, until Nguyễn Huệ burned it about him and Mạn Hòe died in the flames; Phúc Ánh withdrew to Phú Quốc and Gia Định was again subdued. In 1783 Nguyễn Lữ and Nguyễn Huệ came south again and routed Phúc Ánh's army at the Four Channels with their backs to the water, driving him once more to Phú Quốc.

The battle of Rạch Gầm–Xoài Mút in 1785 best displays Nguyễn Huệ's generalship. Fighting the Siamese and having lost several engagements, he thought of withdrawing and making peace; dissuaded by the surrendered Nguyễn officer Lê Xuân Giác, he chose instead to draw the enemy in. On 19 January 1785 the Tây Sơn set ambushes along the banks at Rạch Gầm and Xoài Mút and sent a small party to lure the Siamese from Sa Đéc; the Siamese pursued into the trap, Nguyễn Huệ had his artillery open suddenly on their ships, and in the confusion his land and water forces charged, routing them utterly and pursuing Nguyễn Phúc Ánh, who fled into Siam with a handful of followers. From that battle the Siamese feared the Tây Sơn army, and Nguyễn Huệ's name was made.

In 1786 Nguyễn Huệ was sent against Phú Xuân. He first had a fortune-teller go to the Trịnh commander Phạm Ngô Cầu, foretell illness and advise a seven-day altar and prayers; the commander believed him and set his soldiers to serve at the altar, and the Tây Sơn advanced in force and broke the Trịnh army. Nguyễn Huệ then had a letter urging the deputy commander Hoàng Đình Thể to surrender delivered deliberately to Phạm Ngô Cầu, who suspected his subordinate, failed to support him and let him be killed; the Tây Sơn stormed the city, Phạm Ngô Cầu surrendered in terror, and Huế was taken at once. Nguyễn Hữu Chỉnh then pressed him to exploit the victory northward, arguing that the Trịnh lords' "generals were idle and their soldiers insolent, the court without discipline", and that a campaign in the name of supporting the Lê and destroying the Trịnh would rally all. Nguyễn Huệ, uneasy that he had been ordered only against Phú Xuân and should not forge edicts to march further, at last followed his advice. Advancing under the slogan of supporting the Lê and destroying the Trịnh, he found the commanders of Nghệ An and Thanh Hóa melting away before him; facing the Trịnh fleet at the Vị Hoàng river, he had wooden images set on boats one night, drums beaten and flags waved as they drifted downstream, and the Trịnh admiral Đinh Tích Nhưỡng, taking them for the enemy, formed line and fired until his powder was gone — then Nguyễn Huệ attacked, the admiral fled his ship and Sơn Nam was taken. Pressing on to Thăng Long, he routed the Trịnh lord Trịnh Khải, who charged on his war elephant, was beaten, taken in flight and killed himself; the Trịnh ascendancy in the north was ended. Nguyễn Huệ buried him with royal honors, entered the city to pay his respects to the Lê emperor, was made "generalissimo, duke of Uy", and married Lê Hiển Tông's youngest daughter Lê Thị Ngọc Hân. Nguyễn Nhạc, learning of the uncommanded campaign, came north by forced marches; after a meeting with the Lê emperor the brothers returned south together, leaving the north to the Later Lê.

The rift within the Tây Sơn then widened. According to the False Western Dynasty, Nguyễn Nhạc after taking the imperial title gave himself up to debauchery and killed his own followers, putting Nguyễn Trang to death; the treasure of the Trịnh lord's palace taken in the campaign went wholly to Nguyễn Huệ, who refused to give it up, and Nguyễn Nhạc refused him Quảng Nam in return and even violated his wives, so that the brothers became enemies. Nguyễn Huệ issued a proclamation of his brother's crimes and marched on Quy Nhơn, throwing up earthworks outside the city and bombarding it with shot the size of a peck; Nguyễn Nhạc had the shot gathered and wept with it in the ancestral temple and called down from the wall that a brother should not have the heart to boil meat in a hide, and Nguyễn Huệ, moved, raised the siege, the two making peace with the Bản river as the boundary. Meanwhile the north changed hands repeatedly: Trịnh Bồng gathered the remnants and entered Thăng Long, Lê Mẫn Tông summoned Nguyễn Hữu Chỉnh to rescue the throne, and he drove out the Trịnh only to wield a power like a Trịnh lord's, until Nguyễn Huệ destroyed him.

In 1788 the Qing, professing to restore the Lê, sent Sun Shiyi into Vietnam; he entered Thăng Long, reinstated Lê Mẫn Tông and posted strong forces at Hà Hồi and Ngọc Hồi. Nguyễn Huệ first sent men to Thăng Long with humble apologies to the Qing, lulling Sun Shiyi, then prepared in his ancestral Nghệ An, choosing a hundred thousand soldiers and more than a hundred war elephants, and took the imperial title in 1788 with the era name Quang Trung to hold the people's allegiance. On the third day of the first month of 1789 his army secretly surrounded the camp at Hà Hồi and forced its surrender; on the fifth he advanced on Ngọc Hồi under Qing artillery fire, sending his men forward in groups of twenty carrying three planks lashed together and wrapped in wet rice straw, each man with a dagger at his belt and twenty armed men behind, while he himself directed the attack from a war elephant, and routed the Qing, Sun Shiyi fleeing in haste. After the victory his misgivings about the Qing deepened, and he sought peace: taking the name Nguyễn Quang Bình, he sheltered and repatriated Qing prisoners, laid the blame for the war on Sun Shiyi, negotiated through Fuk'anggan, and sent his nephew Nguyễn Quang Hiển with tribute and a petition for investiture, receiving from the Qianlong emperor the title king of Annam; when Fuk'anggan pressed him repeatedly, Nguyễn Huệ had a double of similar appearance go to the capital in his place, and the Qianlong emperor, believing it, received him at the Rehe lodge and feasted him among the princes. He also took the Chinese pirate chiefs Trần Thiêm Bảo, Lương Quý Hưng and Đàm A Chiêu into his service with rank, supplying them with warships taller and sturdier than their own, so that the pirates of the South China Sea grew from small bands into organized thousands troubling the Chinese coast. In 1792 he sent an envoy to ask for a marriage alliance and for the cession of the two Guangdongs, and gathered his best elephant troops to invade Guangzhou by sea, but fell gravely ill before it could sail; on 27 August of that year he issued a proclamation vowing to destroy Nguyễn Phúc Ánh, who had allied with France. Of his death, the False Western Dynasty says he had dug up the tombs of the Nguyễn lords and was now repaid by their spirits, while modern Vietnamese scholars call it a sudden stroke. After his death the political measures he had introduced were largely abandoned, and the Tây Sơn dynasty, increasingly cut off from the people, lost their support and were destroyed by Nguyễn Phúc Ánh.

Major Activities

Military Contributions

Nguyễn Huệ is described in the Chinese source as one of the outstanding military commanders in Vietnamese history. He joined the Tây Sơn uprising at nineteen and was known for courage and personal leadership in battle. In the wars against the former Nguyễn, he captured Gia Định, seized and killed Nguyễn Phúc Thuần and Nguyễn Phúc Dương, and destroyed the southern Nguyễn regime that had ruled for more than two centuries. At the Battle of Rạch Gầm–Xoài Mút, he used a strategy of drawing the Siamese army into an ambush and decisively defeated it, leaving the Siamese, in the source's phrase, “afraid of Tây Sơn as of a tiger.” In the northern campaign against the Trịnh, he operated under the slogan “support the Lê and destroy the Trịnh,” employed surprise tactics, captured Phú Xuân, advanced through the Vị Hoàng River region and Thăng Long, and ended Trịnh rule in the north. In the war against the Qing, he defeated the Qing expedition and compelled the Qing court to recognize the Tây Sơn regime's rule over Vietnam.

Political Activities

On the basis of his military victories, Nguyễn Huệ established a unified Tây Sơn regime. After proclaiming himself emperor with the era name Quang Trung, he worked to consolidate the state, established diplomatic relations with the Qing, and received investiture from the Qianlong Emperor as King of Annam. He also adopted measures intended to stabilize social order, although the source notes that his short reign prevented many of them from being fully implemented.

Travels and Campaign Geography

Nguyễn Huệ's military activities extended throughout Vietnam. From Gia Định, now Ho Chi Minh City, and Hà Tiên in the south, through Quy Nhơn and Phú Xuân, now Huế, in the center, to Thăng Long, now Hanoi, in the north, he campaigned across the country over little more than a decade and ended more than two centuries of north-south division.

Relations with Contemporaries

Nguyễn Huệ launched the Tây Sơn uprising with his elder brothers Nguyễn Nhạc and Nguyễn Lữ, but later clashed with Nguyễn Nhạc over the division of power, leading to armed conflict. He married the Later Lê princess Lê Ngọc Hân and thereby formed a marital connection with the Later Lê royal house. In the war against the Qing he came into direct military and diplomatic conflict with the Qianlong Emperor's government and with Sun Shiyi, governor-general of Liangguang.

Historical Assessment

Qing / Contemporary Assessments

• The “Vietnam” section of the Draft History of Qing records an assessment attributed to the Qianlong Emperor that Nguyễn Huệ was “fierce and skilled in war” and a dominant military figure of Annam.
• Qing official Sun Shiyi described Nguyễn Huệ in his reports as “using troops like a god,” reflecting his fear of Nguyễn Huệ's military ability.
• The Nguyễn-dynasty official history Đại Nam liệt truyện chính biên sơ tập, in its “Biography of the Spurious Tây Sơn,” described Nguyễn Huệ as having “a voice like a great bell, eyes flashing like lightning, cunning and skilled in fighting.” Although compiled by a hostile regime, it still acknowledged his unusual martial ability.

Nguyễn Dynasty Period in Vietnam

• Official Nguyễn histories labeled the Tây Sơn regime “spurious Tây Sơn” and frequently criticized Nguyễn Huệ, but continued to acknowledge his skill in war.
• The Nguyễn historian Phan Huy Chú wrote in Lịch triều hiến chương loại chí that Nguyễn Huệ “rose from Tây Sơn with the courage of a common man and within ten years possessed both north and south,” acknowledging his capacity as a founder.

Modern Vietnam

• Modern Vietnamese nationalists treated Nguyễn Huệ as a national hero who resisted foreign intervention, and his defeats of Siamese and Qing forces became widely celebrated.
• Vietnamese historian Trần Trọng Kim, in Việt Nam sử lược, described him as exceptionally talented in strategy and regarded him as one of the outstanding military figures of Vietnamese history.

Contemporary Assessments

• The Vietnamese state lists Nguyễn Huệ, the Quang Trung Emperor, among national heroes, and memorial facilities dedicated to him exist in multiple places.
• Although Vietnamese scholarship contains differing assessments, it generally recognizes his historical contribution to ending Vietnam's north-south division.
• Chinese scholars Guo Zhenduo and Zhang Xiaomei, in A General History of Vietnam, described Nguyễn Huệ as “an outstanding military commander” while also identifying his conflict with Nguyễn Nhạc as an important cause of the Tây Sơn dynasty's later collapse.
