army met with little success throughout 190, so in 191 Shao took over Ji Province from Han Fu. When the coalition dissolved, Shao sent men against Yuan Shu's officer Sun Jian in Yingchuan Commandery. Gongsun Zan attacked Shao but was defeated at Jie Bridge between Julu and Qinghe commanderies. Shao set his capital at the city of Ye (Hebei) in Wei Commandery. In 193 Shao attacked the Black Mountain bandits and forced them into hiding. In 195, Zang Hong rebelled against Shao but was defeated and sentenced to death. Shao's follower Chen Rong criticized him of dishonorable conduct and was executed as well. With the support of the Wuhuan, he made the final attack on Gongsun Zan in 198 and eliminated him the beginning of next year. In 199 Shao became hostile to Cao Cao and moved against him. His army moved too slow however and in early winter of 200, Cao Cao destroyed two of his supply trains at the Battle of Guandu. His army scattered and fled. Shao became ill and died in 202. He was succeeded by his son Yuan Shang. Cao Cao attacked in the autumn. By the summer of 203 Yuan Shang had been defeated and driven back to Ye, however Cao Cao decided to withdraw at this point. Shang came into open conflict with his brother Yuan Tan, who fled east. In 204 Shang besieged his brother at Pingyuan Commandery but Cao Cao moved against him at Ye and forced him to flee to Zhongshan Commandery where Tan attacked him. Shang fled again to his other brother Yuan Xi in You Province while Cao Cao attacked Tan at Nanpi in Bohai Commandery and killed him. In 205 Shang and Xi were ejected from their territory by mutineers and fled to the Wuhuan under Tadun, but Tadun was defeated by Cao Cao at the Battle of White Wolf Mountain in 207. They fled for the last time, this time to Gongsun Kang, who killed them and sent their heads to Cao Cao. Yuan Shu Yuan Shu was born to a highly distinguished official family who had held office as one of the Three Ducal Ministers, the three highest posts below emperor, for three generations. Despite acquiring a respectful reputation for himself and later becoming General of the Household Rapid as Tigers, Yuan Shu was ultimately overshadowed by his more popular and successful half-brother Yuan Shao.
