Xiahou Ba
Xiahou Ba (died 255–259), courtesy name Zhongquan, was a military general of the state of Cao Wei in the Three Kingdoms period of China. He was the second son of Xiahou Yuan, a prominent general who served under Cao Cao, the warlord who laid the foundation for the state of Cao Wei. Around 249, Xiahou Ba defected to Wei's rival state, Shu Han, after the regent Sima Yi seized power in a coup d'état. He was killed in battle sometime between 255 and 259 against Wei forces.
