“Hubris, means extreme pride or self-confidence. Hubris often indicates a loss of contact with reality and an overestimation of one’s own competence, accomplishments or capabilities, especially when the person exhibiting it is in a position of power.”
“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.“
“The Battle of Bạch Đằng, which took place at the Bach Dang River, near Ha Long Bay in present-day northern Vietnam, was a battle betweenĐại Việt and the invading army of the Yuan Dynasty. It is considered part of the Third Mongol Invasion (1287-88).“
“In 1288 after the evacuation from the capital Thăng Long (present-day Hanoi), Đại Việt’s Grand Commander Trần Hưng Đạo decided to launch an offensive against the Mongolians on the Bạch Đằng River and immediately set to organize the battle.
The Bạch Đằng River ran through Yen Hung district (in Quảng Ninh province) and Thuy Nguyen (in Hai Phong) before reaching the sea. This is where the well-known battle of Ngô Quyền against the Southern Han (Nanhan) took place in 938 A.D. It was from March, Trần Hưng Đạo was already there to prepare the battlefield. He borrowed the same tactic that Ngô Quyền used against the Chinese in 938. He studied the tidal lore, had beds of stakes planted under the water and arranged ambushes in a unified plan of campaign.”
“The Mongolian supply fleet was totally destroyed. Omar was captured.
At the same time, Đại Việt’s Army made continuous attacks and smashed to pieces Toghan’s army on its route of withdrawal through Lạng Sơn. Toghan risked his life making a shortcut through forests to flee home.”
“The Sino-Vietnamese War also known as the Third Indochina War, was a brief border war fought between the People’s Republic of China and the Socialist Republic of Vietnam in early 1979. China launched the offensive in response to Vietnam’s invasion and occupation of Cambodia in 1978 (which ended the rule of the Chinese-backed Khmer Rouge). Chinese Vice-premier Deng Xiaoping saw this as a Soviet attempt “to extend its evil tentacles to Southeast Asia and…carry out expansion there,” which reflected the long-standing Sino-Soviet split. As the former U.S. Secretary of State Henry Kissingernotes: “[w]hatever the shortcomings of its execution, the Chinese campaign reflected a serious, long-term strategic analysis.”
The Chinese entered northern Vietnam and captured some of the bordering cities. On March 6, 1979, China declared that the gate to Hanoi was open and that their punitive mission had been achieved. Chinese forces retreated back across the Vietnamese border, into China. Both China and Vietnam claimed victory in the last of the Indochina Wars of the 20th century; as Vietnamese troops remained in Cambodia until 1989, and the Hanoi imposed regime remains in power in Cambodia till today (2014), it can be said that China failed to achieve the goal of dissuading Vietnam from involvement in Cambodia. Following the dissolution of the Soviet Union, the Sino-Vietnamese border was finalized.”
