Yu Fan
In 232, Sun Quan had another misadventure involving his navy — as he sent his generals Zhou He () and Pei Qian () to the nominal Wei vassal Gongsun Yuan, in control of Liaodong Commandery, to purchase horses, against the advice of Yu Fan - and indeed, he exiled Yu Fan to the desolate Cangwu Commandery (roughly modern Wuzhou, Guangxi) as punishment. Just as Yu Fan predicted, however, the venture would end in failure — as Zhou He and Pei Qian, on their way back, were intercepted by Wei forces and killed. Regretting his actions, Sun Quan tried to recall Yu Fan back to Jianye, only to learn that Yu had died in exile.
