吕布
Cao Cao defeated Lü Bu in numerous battles and eventually surrounded him at Xiapi. Lü Bu tried to break free but could not do so. Ultimately, many of his officers and soldiers defected to Cao Cao. Some were kidnapped by defectors. Lü Bu grew disheartened and surrendered to Cao Cao, who executed him on 7 February 199. By eliminating Lü Bu, Cao had obtained effective control of Xu Province.
