Wei Qing's army, setting off from Dingxiang, encountered Yizhixie Chanyu's army. Wei Qing ordered his troops to arrange heavy-armoured chariots in a ring formation, creating mobile fortresses that provided archers, crossbowmen, and infantry protection from the Xiongnu's cavalry charges, and allowing the Han troops to utilize their ranged weapons' advantages. A 5000-strong cavalry was deployed to reinforce the array against any Xiongnu attack. The Xiongnu charged the Han forces with a 10,000-strong vanguard cavalry. The battle solidified into a stalemate until dusk, when a sandstorm obscured the battlefield. Subsequently, Wei Qing sent in his main forces and overwhelmed the Xiongnu. The Han cavalry used the low visibility as cover and encircled the Xiongnu army from both flanks, but Yizhixie Chanyu and a contingent of troops broke through and escaped.
