Cui Liang

Governor of Anding and the hinge of the whole three-city deception. Frightened into mustering his four thousand, taken in by the false Pei Xu and his sweat-soaked letter, then by a second messenger claiming Tianshui has already marched. Marches, is ambushed between Guan Xing and Zhang Bao, cuts out with a hundred men — and comes home to arrows from his own wall and Wei Yan telling him to yield. Surrenders, is treated with courtesy, and immediately plays double: agrees to talk Yang Ling into seizing Xiahou Mao, then plots with him to kill the escorts and lure Zhuge Liang in, and shoots a warning letter over the Nanan wall on an arrow. Zhang Bao spears him as he turns to run.
