Battle of Bạch Đằng (938)

At the Battle of Bạch Đằng River in 938 the Vietnamese forces, led by Ngô Quyền, defeated the invading forces of the Southern Han state of China and put an end to centuries of Chinese imperial domination in Vietnam. It took place at the Bạch Đằng River, near Hạ Long Bay in northern Vietnam.^[1]

In 937, Liu Yan (Chinese: 劉龑; Vietnamese: Lưu Nham), the Southern Han ruler, took the chance to intervene in Vietnam again after the death of the Annam Lord Protector Dương Đình Nghệ. He had been foiled by Dương Đình Nghệ in 931, but now that Dương Đình Nghệ was dead, he thought the time was ripe for another attempt. He placed his own son, Liu Hongcao (Chinese: 劉弘操; Vietnamese: Lưu Hoằng Tháo), in command of the expedition, naming him "Peaceful Sea Military Governor" and "King of Giao." He hastily assembled an army at Sea Gate, where he personally took charge of the reserve force. He ordered Liu Hongcao to embark the army and sail to Giao.

By the time Liu Hongcao arrived in Vietnamese waters with the Southern Han expedition, Liu Hongcao's plan was to ascend the Bạch Đằng River and to place his army in the heart of Giacannoto Chau before disembarking; the Bạch Đằng was the major riverine route into the Red River plain from the north.

Ngô Quyền anticipated this plan and brought his army to the mouth of the river. He had his men plant a barrier of large poles in the bed of the river. The tops of the poles reached just below the water level at high tide and were sharpened and tipped with iron. When Liu Hongcao appeared off the mouth of the river, Quyen sent out small, shallow-draft boats at high tide to provoke a fight and then retreat upriver, drawing the Chinese fleet in pursuit. As the tide fell, the heavy Chinese warboats were caught on the poles and lay trapped in the middle of the river, whereupon they were attacked by Ngô Quyền's forces. More than half the Chinese were drowned, including Liu Hongcao.^[2] When news of the battle reached Sea Gate with the survivors, Liu Yan wept openly. He collected what remained of his army and returned to Canton. This victory ended China's long domination of Vietnam and began a period of Vietnam's independence until the conquest by Ming China. Ngô Quyền's tactic would later be reused by Trần Hưng Đạo in a battle at Bạch Đằng River against the Mongols in 1288.

Background

In 931 AD, Dương Đình Nghệ defeated the Southern Han army – one of the Ten Kingdoms near Tĩnh Hải quân (Army of Peaceful Sea, the name used for Vietnam's army at that time) and achieved the independent status of the Vietnamese at Tĩnh Hải quân; he named himself Jiedushi.^[3]

In 937 AD, Đình Nghệ was killed by Kiều Công Tiễn to revoke the Jiedushi title. Đình Nghệ's son in law and also his general, Ngô Quyền, mobilized his army to revenge Công Tiễn.^[3]

Feared of Ngô Quyền, Công Tiễn requested help from the Southern Han. Thereforce, Emperor of Southern Han, Liu Yan took his chance and prepare to invade Tĩnh Hải (Peaceful Sea) again.^[3]

Liu Yan claimed that if Dương Đình Nghệ was dead, then Tỉnh Hãi Quân would be out of good generals. He ordered his ninth son, Liu Hongcao (Vietnamese: Lưu Hoằng Tháo) to become "Bình Hải tướng quân" (Sea-Pacifying Military General) and "Giao Chỉ vương" (King of Giao Chỉ), he commanded the naval forces of Southern Han into Giao Chỉ.^[3]

Executing the protestors

In the year 938 AD, after calling of all the soldiers in the nation to his side, Ngô Quyền led his army from Ái Châu to the North to kill Kiều Công Tiễn. Công Tiễn was surrounded by Ngô Quyền's army and could not resist. He waited for the reinforcements of Southern Han.^[3]

The Emperor of Southern Han, Liu Yan, gave his son Liu Hongcao the title Tĩnh Hải quân's Jiedushi,^[3] then Hongcao's title was changed rather prematurely into King of Giao (Jiaozhi). He led over twenty thousand troops into Giao Chỉ in the name of "Công Tiễn's Reinforcements".^[3] Liu Yan asked Chongwen's courtier (known by the Vietnameses as Tiêu Ích) for advice. Ích said:

The Han Emperor wanted to move fast and quickly reconquer Tĩnh Hải, so he didn't listen to the advice of Tiêu Ích. He ordered Hongcao to lead his army into the river of Bạch Đằng immediately. Emperor Liu Yan, as a general himself, stayed at Haimen as an alternative reinforcement.

While Liu Yan was mobilizing his army, Ngô Quyền marched to Đại La to kill Kiều Công Tiễn. Công Tiễn at that time, completely surrounded by Ngô Quyền's forces and was killed beforce the Southern Han's reinforcements march into the borders of Vietnam.^[3]

The pole and tide tactic

Ngô Quyền knew that Hongcao was coming, and told his generals:^[3]

Ngô Quyền ordered his soldiers to nail the iron-headed poles under the waters of the Bạch Đằng river. At high tide, the poles would be covered with water, and thus, remain unseen by the Chinese. Ngô Quyền intended to lure the enemy into this area when the tide was up. When the tide was down, the enemy's boats would be stranded, and be easy targets for attack.^[3]

On a late winter day in 938 AD, on Bạch Đằng River, the entire Han's naval fleet led by Hongcao entered Tĩnh Hải.^[3]

The Southern Han's soldiers, seeing the small ships of Ngô Quyền, argressively marched in, thinking that they could easily defeat the small force of Ngô Quyền. Ngô Quyền ordered his army to retreat upstream. He waited until the tide lowered and ordered his army to fight back. The big ships of Southern Han were stranded and penetrated by the poles. At that time, Ngô Quyền used all of his forces to attack. The Southern Han's Army lost the battle and retreated, Liu Hongcao and more than half the force was killed by the Vietnamese.^[3]

The Emperor of Southern Han was leading his army at the borders, so he could not respond to the situation. Hearing the news that Hongcao was dead, Liu Yang was horrified, and ordered his remaining forces to retreat (^[4]). After that, the dynasty of Southern Han forgot about invading Tĩnh Hải quân.^[4]

Year 939, Ngô Quyền became King, took the title Ngô Vương (Ngô King), created Vietnam's Ngô Dynasty, set his capital at Cổ Loa (Today's Đông Anh, Hà Nội).^[5]

Later, in Battle of Bạch Đằng (1288), Trần Hưng Đạo would reuse this tactic to win against the Mongols.^[6])

Tactics

The military tactics used by Ngô Quyền were original, as Lê Văn Hưu described: "Great tactic, good combat" (Vietnamese: "Mưu giỏi mà đánh cũng giỏi" or "mưu tài đánh giỏi") in Complete History of Đại Việt (Đại Việt sử ký toàn thư).^[5] However, according to militarists, applying the pole-and-tide stratagem to inflict damage upon an enemy navy required the successful combination of two factors:

• First, lure the enemy past the poles when at high tide as the poles are hidden.
• Second, know the tide and calculate the time when the tide ebbs, and ensure the enemy ships are above the poles at this point, causing them to be impaled on the poles and sunk.

These two processes were integrally linked, for if the enemy came in at low tide, they would have seen the poles, but if low tide did not come in time, Liu's boats would have easily sailed over the poles.

This is the situation that the militarists of Vietnam recorded of Battle of Bạch Đằng (981), that the Song's army (Vietnamese: Lưu Hoằng Tháo) passed the poles and forward into the land without obstacles (But then they were tricked by Lê Hoàn and was defeated.

Therefore, for this tactic to take effect, beside preparing the poles secretly and quickly, luring the enemy into the right route at the right time was the most decisive factor. Ngô Quyền achieved success with this tactic by calculating and predicting the tides.

One general who reused this tactic was Trần Hưng Đạo in the Battle of Bạch Đằng (1288); Trần Hưng Đạo also understood the requisites behind this tactic and applied them successfully in pushing the Mongol army out of the Bạch Đằng River. Using poles to destroy ships is not easy to pull off: it is no coincidence that both Ngô Quyền and Trần Hưng Đạo are considered great generals in the History of Vietnam.

Significance of the Battle

The great victory at Bạch Đằng, 938, has an important significance to Vietnam, because it ended 1000 years of First Chinese domination of Vietnam (The Long Eclipse) in History of Vietnam, opening up an independence age for the nation of Vietnam.

The Victory of Bạch Đằng is the victorious final of Vietnam in the fighting the Chinese domination and assimilation to retake the independence of Vietnamese people. The full great meaning of this victory can only be seen in the background of the 1117 years Long Eclipse.

Moreover, in those 1000 years, the enemy of the Vietnamese people is a large empire, one of the highest military positions in the Eastern Asia, with the Han's expansionism increasing at it highest rate. Especially under the Eastern Han Dynasty, Tang Dynasty. Continuing the expansion of Qin Shi Huang, the Han Dynasty successfully conquered Northern Korea and the nomads in the North, expanded its borders to Middle Asia and invaded the countries at the South Western. In the 7th century, the Sui conquered today's Taiwan, Giao Châu (North Vietnam), and Tây Đồ Quốc..., the Tang Dynasty expanded in all directions, formed a vast empire as Emperor Taizong of Tang declared: "I have conquered more than 200 kingdoms, parcified both four directions, the Di Mans at the far land have to come here and serve me".^[7]

In the first century CE, the population of Han's empire was over 57 million. At that time, the population of Vietnam was just over 1 million. After the conquest of Vietnam, the plot of the Han Dynasty not just stopped at destroying the national sovereignty, exploiting the people, scavenging the treasures of Vietnam but also assimilate the entire Vietnamese people forever, annex the lands into China. The Chinese assimilation plan is a feature of Han expansionism, was used from the Han's Dynasty to the Tang. In the entire History of Vietnam, this is one of the most dangerous and destinying time that the Vietnamese people must pass.^[8]

Ngô Quyền – the hero in the great Victory of Bạch Đằng in 938, is the King that has rebuilt Vietnam, King of the Kings, as the Đại Việt sử ký toàn thư described.^[4] Phan Bội Châu said: "He is surely worthy with the title "The Mid-Ancestor" of Vietnameses people."

After victory of Bạch Đằng, Vietnam entered a new age to rebuild the country in large-scale. That is the age of the modern Đại Việt, of Thăng Long's traditional, the age of defeating the Song, defending against the Mongols, liberating from the Ming, a golden age of Lý Dynasty, Trần Dynasty, Lê Dynasty.^[8]
