Xiahou Ba
Guo Huai split his army into two groups with the aim of preventing Jiang Wei from meeting up and combining forces with Zhiwudai. He led one group to attack Liao Hua at Chengzhong Mountain to force Jiang Wei to turn back to save Liao Hua. At the same time, he ordered his subordinate Xiahou Ba to attack Jiang Wei and push him back towards Tazhong (沓中; northwest of present-day Zhugqu County, Gansu). Guo Huai's plan succeeded as Jiang Wei turned back to save Liao Hua when he learnt that Chengzhong Mountain was under attack. In doing so, he failed to meet up with Zhiwudai and eventually retreated back to Shu.
