Mi Fang
In 219, Mi Fang defected to Sun Quan when Sun's general Lü Meng launched a surprise attack on Jing Province (covering present-day Hubei and Hunan), which resulted in the death of Guan Yu. Mi Zhu bound himself and came to Liu Bei, pleading guilty for his brother's crime. Although Liu Bei did not fault him, Mi Zhu was so ashamed that he soon fell sick and died slightly more than a year later.
