Yellow Wolf or He–Mene Mox Mox (born c. 1855, died August 1935) was a Nez Perce warrior who fought in the Nez Perce War of 1877. In his old age, he decided to give the war a Native American perspective. From their meeting in 1907 till his death in 1935, Yellow Wolf talked annually to Lucullus Virgil McWhorter, who wrote a book for him, Yellow Wolf: His Own Story. He is notable as one of the few members of the defeated Nez Perce to talk openly to strangers and tell their story to the world.
Others of his tribe said he was making a fool of himself for talking to a white man, saying that the children of the tribe would tell the story. In spite of that, he continued to work with McWhorter. In telling the native's side he said, "I am telling my story that all may know the war we did not want. War is made to take something that is not your own." He was concerned that the next generation of Native Americans would continue to suffer under white oppression, and wrote to help them. He said, "the young generation behind me, for them I tell the story. It is for them! I want the next generation of whites to know and treat the Indian as themselves.
