Jiang Ban

One of the two advisers whose defection starts the collapse. With Jiao Yi he tells Zhuge Dan the truth — 'The food in the city is short, and the soldiers are many; this can not last long' — is threatened with death as a traitor for it, and concludes on the way out: 'He is lost! We can do no other than surrender or we shall die too.' They go over the wall that night and are both given employment.
