In 123 BC, Wei Qing set off from Dingxiang (定襄) and returned with several thousand enemy kills. A month later, Wei Qing again launched from Dingxiang, but would fight a relatively inconclusive battle. Although he was able to kill/capture more than 10,000 Xiongnu soldiers, part of his vanguard forces, a 3,000-strong regiment commanded by generals Su Jian and Zhao Xin (a surrendered Xiongnu prince), encountered a Xiongnu force led by Chanyu Yizhixie (伊稚斜單于), and was outnumbered and annihilated. Zhao Xin defected on the field with his 800 ethnic Xiongnu subordinates, while Su Jian escaped after losing all his men in the desperate fighting. Showing compassion on Su Jian, Wei Qing spared him even though some advocates advised him to execute Su on the spot after court martial to enforce his commanding authority. Due to the loss of Su's detachment, Wei Qing troops did not earn any promotion, even though they scored more gains than losses. At this campaign, his nephew Huo Qubing distinguished himself in battle and was given his own command.
