袁绍
In order to focus on the conflicts with Gongsun Zan, Yuan Shao entered into a general alliance with Liu Biao against Yuan Shu. In the winter of that year, Yuan Shao defeated Gongsun Zan's elite cavalry at the Battle of Jieqiao with the use of massed crossbowmen. The Han imperial court issued an edict ordering Yuan Shao and Gongsun Zan to cease fire. Yuan Shao then returned to Ye and started targeting the Heishan bandits, who had been causing trouble in Ji Province. With temporary aid from Lü Bu, Yuan Shao managed to defeat the Heishan bandits despite suffering heavy casualties. In any case, Yuan Shao succeeded in drastically reducing the threat posed by the Heishan bandits to his western flank.
