Hanzhong Campaign
After occupying Yi Province, Liu Bei appointed Ma Chao as General Who Pacifies the West (平西將軍) and put him in charge of Linju (臨沮; northeast of present-day Yuan'an County, Hubei). Liu Bei defeated Cao Cao in the Hanzhong Campaign in 219 and declared himself "King of Hanzhong" (漢中王), after which he appointed Ma Chao as General of the Left (左將軍).
