孟達
In 219, Meng Da was ordered to lead a force from Zigui () to attack Fangling (). After conquering Fangling, Meng Da advanced further north and captured another city, Shangyong (), where he rendezvoused with Liu Feng, Liu Bei's adoptive son. Later that year, when Liu Bei's general Guan Yu was trapped by enemy forces in Jing Province, Guan requested reinforcements from Liu Feng and Meng Da, but they refused. Guan Yu was eventually captured by forces of the eastern warlord Sun Quan and was executed.
