Yuan Shang
Following Yuan Shao's death in 202, his son and successor Yuan Shang continued maintaining friendly ties with the Wuhuan. When Yuan Shang was defeated by his father's rival Cao Cao and forced to flee further north, he took shelter under Tadun and the Wuhuan tribes. Tadun attempted to help Yuan Shang regain control over the territories in northern China but to no avail. In 207, Cao Cao personally led his forces on a campaign against Yuan Shang and the Wuhuan tribes. By the time the Wuhuan realised that Cao Cao was on his way to attack them, it was a little too late but they still managed to muster thousands of horsemen to fight the enemy. Both sides clashed at the Battle of White Wolf Mountain near Liucheng (柳城; southwest of present-day Chaoyang, Liaoning). During the battle, Tadun was captured by the "Tiger and Leopard Cavalry" (虎豹騎) unit led by Cao Cao's cousin Cao Chun and was later executed by Zhang Liao, a general under Cao Cao.
