Ngô Quyền (897–944) was Dương Đình Nghệ's most loyal general and son-in-law.
He served under Dương Đình Nghệ's command and married one of his daughters.
After the murder of father-in-law, Ngô Quyền sought revenge.
He launched an attack and defeated Kiều Công Tiễn in 938.
The latter, before his death in battle with Ngô Quyền, sent an emissary to Southern Han court to ask for military re-enforcement.
The Southern Han state's emperor then sent an army to the South land to assist Kiều Công Tiễn in 938.
However, Ngô Quyền's forces were tipped off over the advancing Southern Han army and therefore he quickly mobilized his forces and strategically stationed them in key battle sites.

To defeat the Southern Han army coming to supply aid to his rival, Ngô Vương cleverly planted iron spikes underneath the Bạch Đằng River and timed the attack of the Southern Han navy.
The attack began during high tide to conceal the spikes beneath the water.
After the Vietnamese held the enemy in check for hours, the tides receded and the spikes impaled the Chinese armada.
The Vietnamese forces followed this impalement with ferocious fire attacks, which annihilated hundreds of giant warships.
The Southern Han navy and the Prince of Southern Han were killed in the battle.
This tactic was repeated again during the Trần Dynasty by Trần Hưng Đạo against the third Mongol invasion of 1288.
