Zhang Song
When Zhang Song's true intentions were revealed to Liu Zhang by Zhang Song's elder brother Zhang Su, he executed Zhang Song and began his battle against Liu Bei, who then began his conquest of Yi Province. Although generals such as Zhang Ren fought hard to defend their master, Liu Bei's forces had the upper hand, and by 214 they had surrounded Yi Province's capital, Chengdu. Liu Zhang's advisers Liu Ba, Dong He and Hu Jing pleaded to their master to resist at all costs, but Liu Zhang rejected their pleas, saying "I don't want my subjects to suffer any more." He then surrendered to Liu Bei.
