夷陵之战
In 221, after the collapse of the Eastern Han dynasty, Liu Bei declared himself emperor and established the state of Shu Han. Ma Liang was appointed as a Palace Attendant () in Shu. Later that year, Liu Bei launched a campaign against Sun Quan, leading to the Battle of Xiaoting. Ma Liang was tasked with persuading the tribal peoples in Wuling (武陵; around present-day Wuling District, Changde, Hunan) to join Liu Bei and he succeeded in his mission. Liu Bei was eventually defeated by Sun Quan's general Lu Xun at the Battle of Xiaoting in 222 and Ma Liang was killed in action. Later, after he managed to retreat to Baidicheng (in present-day Fengjie County, Chongqing) safely, Liu Bei appointed Ma Liang's son, Ma Bing (), as a Cavalry Commandant ().
