The Northern Xiongnu remained a persistent threat to Han dynasty territory and allied Southern Xiongnu. The Han court, seeking to neutralize this threat, organized a large multi-column punitive expedition in 89 AD, deploying forces from Jilu, Manyi, and Guyang alongside Southern Xiongnu allies under the command of General Dou Xian.
In June 89 AD, Dou Xian led Han and Southern Xiongnu forces into the Altai Mountains, engaging the Northern Chanyu in a decisive battle. A large detachment swept northwest, defeated the Northern Chanyu's forces, and pursued them westward. The campaign resulted in 13,000 Xiongnu killed and the surrender of approximately 200,000 individuals from 81 tribes.
Following the victory, Dou Xian led his troops north to the Khangai Mountains and commemorated the campaign by commissioning the Inscription of Yanran, carved into a cliff and composed by historian Ban Gu. The defeat severely weakened the Northern Xiongnu and accelerated their westward migration, with long-term implications for the population movements across Central Asia.
