Meng Da
In 228, Zhuge Liang launched the first of a series of Northern Expeditions against Wei, and he succeeded in persuading Meng Da to assist the Shu army by rebelling against Wei. However, Meng Da's rebellion plot was leaked out by Shen Yi (), the Administrator of Weixing (), whom Meng Da had a feud with. The Wei general Sima Yi wrote letters to Meng Da to put the latter in a dilemma on whether to rebel or not, and secretly led an army from Wan (in present-day Nanyang, Henan) to attack Meng Da's base in Xincheng. Sima Yi's forces arrived at Xincheng in just eight days and caught Meng Da completely off guard. Meng Da was betrayed by his nephew Deng Xian () and subordinate Li Fu () and his rebellion was swiftly suppressed. He was captured and executed by Sima Yi.
