Zhang Lu
Ma Chao and Han Sui were defeated by Cao Cao at Huayin and retreated west. In 213 Ma Chao made an alliance with the Qiang and Di people as well as Zhang Lu. He then seized Hanyang Commandery. In the autumn an uprising by Yang Fu and Jiang Xu defeated Ma Chao and forced him to take refuge with Zhang Lu. Zhang Lu provided Ma Chao with troops to make an attempt to re-establish himself in Liang Province, but Ma Chao was defeated by Xiahou Yuan. Realizing that Zhang Lu would not provide him with any more troops, Ma Chao joined Liu Bei, who made him a general. Under Liu Bei, Ma Chao campaigned against Cao Cao in Wudu Commandery in 217 but failed to make any headway. Ma Chao died in 222.
