Цзян Вэй
In Chapters 92 and 93 of the 14th-century historical novel "Romance of the Three Kingdoms", Jiang Wei was one of the reasons Zhuge Liang went on this expedition, and getting Jiang to defect to Shu became a goal after his quick battle with Zhao Yun. Zhuge Liang sent Zhao Yun ahead first, and after a skirmish and some scheming he comes onto the battlefield. During the battle, Ma Zun (馬遵) suspected Jiang Wei of plotting with the enemy. When Jiang Wei was outside Tianshui, Ma Zun closed the city gates and denied Jiang Wei entry. Jiang Wei had no choice but to defect to Zhuge Liang's side.
