A word for Li Ling
Li Ling led five thousand foot soldiers deep into Xiongnu territory, fought for eight days until his arrows and grain ran out, and surrendered. Emperor Wu was furious, and all the officials called for his clan’s extermination. Sima Qian spoke up: Li Ling had fought across a thousand miles, inflicting losses beyond his numbers, and might have surrendered to await a chance to repay the Han. Emperor Wu convicted him of "slandering the emperor" and had him castrated. He later wrote in the "Letter to Ren An" that he "endured and clung to life, hidden in filth without refusing," only because "I grieved that my private heart had not fully expressed itself, that I might pass from the world in obscurity with my writing unshown to later ages."
