袁熙
The Battle of White Wolf Mountain was a battle fought in 207 in the late Eastern Han dynasty of China. The battle took place in northern China, beyond the frontiers of the ruling Eastern Han dynasty. It was fought between the warlord Cao Cao and the nomadic Wuhuan tribes, who were allied with Cao Cao's rivals Yuan Shang and Yuan Xi. The victory attained by Cao Cao dashed the hopes of a Wuhuan dominion, and the Wuhuan eventually became weakened, lost importance, and were gradually absorbed into China or the Xianbei tribes.
