On November 11, 1921, for the consecration of the Tomb of the Unknown Soldier at the Arlington National Cemetery, Chief Plenty Coups, a Crow Indian, was chosen to represent all Native Americans. He came to the ceremony with gifts, a warbonnet and a coup stick and captured the audience with a moving speech, saying among other things that he was "glad to represent all the Indians of the United States in placing on the grave of this noble warrior this coup stick and war bonnet. His two presents were later put in a show case labeled "Chief Plenty Coups, American Indians" in the trophy room of the Arlington Cemetery.
