Bạch Đằng River
Kiều Công Tiễn or Kiểu Công Tiện () (矯公羡) was a general in the court of Dương Đình Nghệ, a Vietnamese Jiedushi of Tĩnh Hải quân who took over the position in 931. In 937 Kiều Công Tiễn assassinated the Jiedushi to seize his position and thus provoked a revolt led by Ngô Quyền who sought revenge his lord and father-in-law Dương Đình Nghệ. In response to the attack, Kiều Công Tiễn appealed to Liu Yan, the emperor of Southern Han, for reinforcements but he was defeated and executed by Ngô Quyền before the army of Southern Han entered the country. Later, Ngô Quyền had a decisive victory over the Southern Han in the Battle of Bạch Đằng River and marked the independence of Vietnam from Chinese authorities.
