孟達
The "Book of Jin" and "Zizhi Tongjian", however, are in agreement that Sima Yi, upon hearing that Meng Da wished to rebel, instead wrote a flattering letter to Meng Da to distract and confuse him while preparing to suppress the rebellion. While Meng Da was stuck in a dilemma on whether to commit to his rebellion or not, Sima Yi swiftly assembled his troops and in secret led them to attack Meng Da's base in Shangyong Commandery (上庸郡; around present-day Zhushan County, Hubei).
