Qing and giving the younger Huo Qubing more attention and favour, hoped that Huo would engage the stronger Chanyu's tribe and preferentially assigned him the most elite troopers. The initial plan called for Huo Qubing to attack from Dingxiang (定襄, modern-day Qingshuihe County, Inner Mongolia) and engage the Chanyu, with Wei Qing supporting him in the east from Dai Commandery (代郡, modern-day, Yu County, Hebei) to engage the Left Worthy Prince (). However, a Xiongnu prisoner of war confessed that the Chanyu's main force was at the east side. Unaware that this was actually false information provided by the Xiongnu, Emperor Wu ordered the two columns to switch routes, with Wei Qing now setting off on the western side from Dingxiang, and Huo Qubing marching on the eastern side from the Dai Commandery. Battles at the eastern Dai Commandery theatre were quite straightforward, as Huo Qubing's forces were far superior to their enemies. Huo Qubing advanced over 2,000 li and directly engaged the Left Worthy Prince in a swift and decisive battle. He quickly encircled and overran the Xiongnu, killing over 70,000 men, and capturing three lords and 83 nobles, while suffering a 20% casualty rate that was quickly resupplied from local captives. He then went on to conduct a series of rituals upon his arrival at the Khentii Mountains (狼居胥山, and the more northern 姑衍山) to symbolize the historic Han victory, then continued his pursuit as far as Lake Baikal (), effectively annihilating the Xiongnu clan and allowing conquering tribe such as the Donghu People to retake back their land to establish their own confederacy to declared independent from Xiongnu Overlord following the subjugation for over a few decade. A separate division led by Lu Bode (), set off on a strategically flanking route from Right Beiping (右北平, modern-day Ningcheng County, Inner Mongolia), joined forces with Huo Qubing after arriving in time with 2,800 enemy kills, and the combined forces then returned in triumph. This victory earned Huo Qubing 5,800 households of fiefdom as a reward, making him more distinguished than his uncle Wei Qing. At the height of his career, many low-ranking commanders previously served under Wei Qing voluntarily transferred to Huo Qubing's service in the hope of achieving military glory with him. Death and legacy Emperor Wu offered to help Huo Qubing build up a household for marriage. Huo Qubing, however, answered that "the Xiongnu are not
