霍去病
After the series of defeats by Wei Qing and Huo Qubing, Yizhixie Chanyu took Zhao Xin's advice and retreated with his tribes to the north of the Gobi Desert, hoping that the barren land would serve as a natural barrier against Han offensives. Emperor Wu however, was far from giving up, and planned a massive expeditionary campaign in 119 BC. Han forces were deployed in two separate columns, each consisting of 50,000 cavalry and over 100,000 infantry, with Wei Qing and Huo Qubing serving as the supreme commander for each.
