夏侯霸
In the 240s, Xiahou Ba was enfeoffed as the Marquis of Bochang Village and became a close associate of Cao Shuang, Cao Zhen's son and a regent to the Wei emperor Cao Fang. When Cao Shuang decided to wage war against Shu to enhance his personal influence and reputation, Xiahou Ba was made Protector of the Army and came under command of Xiahou Xuan, who was the marquis's son in the clan. For the ensuing campaign, however, the Wei general Guo Huai, whom Xiahou Ba disliked, had the honour of leading the vanguard. This time, Wei forces chose the shorter Tangluo Trail into Shu territory, but again experienced logistic problems as a long section of the trail had no water source. As a result, the Wei forces had no choice but to retreat, and many soldiers merely died of thirst along the way back. After the war, Guo Huai, due to his timely withdrawal of troops, was granted a higher military authority over Xiahou Ba.
