陳泰
When Jiang Wei led troops from Mount Niutou (牛頭山; west of present-day Zhaohua District, Guangyuan, Sichuan) to reinforce the two fortresses, Chen Tai led a Wei army to block his path. At the same time, Chen Tai sought help from Guo Huai, who led his troops across the Tao River to attack Jiang Wei's base at Mount Niutou. Jiang Wei became fearful so he pulled back all his troops and abandoned the two fortresses.
