Yue Jin
As a result of the disastrous defeat at the Red Cliffs, Cao Cao's huge army was scattered around the northern plain above the Yangtze River. Yue Jin was ordered to station inside the city of Xiangyang, in anticipation of counterstrikes by Sun Quan's general Zhou Yu. When Liu Bei's general Guan Yu was attempting to cut the connection between Jiangling County and Xiangyang, he was stymied by Yue Jin, who led his army out and defeated him. During Guan Yu's second attempt to block the waterway of Xiangyang, Yue Jin attacked Guan Yu again on the water near Xiakou (夏口; in present-day Wuhan, Hubei) and drove him away.
