Killed by His Own Being Right
Before Yuan Shao resolved to march against Cao Cao, Tian Feng strenuously opposed it, holding that he should first rest and recover his strength and wait for the moment; Yuan Shao, refusing, imprisoned him instead. When word of the defeat at Guandu came, his fellow prisoners were glad for Tian Feng, thinking he would soon be freed and promoted for his accurate foresight, but Tian Feng sighed: "had my lord won and returned, I might yet have lived; now that he has lost, I am sure to die." And so Yuan Shao, feeling his face utterly lost, ordered him executed — a man killed for having spoken rightly, the most ironic footnote to Guandu.
