漢中之戰
After taking Hanzhong Commandery by defeating Cao Cao in the Hanzhong Campaign in May 219, Liu Bei further expanded his territorial gains in June 219 by sending Meng Da and Liu Feng to take Fangling (房陵; present-day Fang County, Hubei) and Shangyong (上庸; north of present-day Zhushan County, Hubei) commanderies. Cao Cao was temporarily forced to be on the defensive after these continuous setbacks.
