Battle of Xiangyang
Yuan Shu had previously set up his headquarters in Nanyang in 189, but after losing the Battle of Xiangyang (191) in which his best general Sun Jian was killed, he withdrew to Chenliu in the east, and began expanding his influence in Yang Province in 192. Suffering heavy defeats at the hands of Yuan Shao and Cao Cao, Yuan Shu was forced to flee, and relocated his base to Shouchun in Jiujiang (present-day Shou County, Anhui) on the southern bank of the Huai River.
