In June AD 89, the Han dispatched a force which promptly advanced from Jilu, Manyi, and Guyang in three great columns that included their allies, specifically the main army of the Southern Xiongnu. The force of General Dou Xian advanced towards the Northern Chanyu into the Altai Mountains. A large detachment then moved to the northwest, and in the major battle of the campaign they defeated the Northern Chanyu at the Altai Mountains and pursued them westwards. The Han forces killed 13,000 Xiongnu troops and accepted the surrender of 200,000 Xiongnu from 81 tribes.
