However, see Eastman, p. 165: "In the early part of the year 1876, there was a rumor that certain bands were in danger of breaking away. Their leader was one Sioux Jim, so nicknamed by the soldiers. American Horse went to him as peacemaker, but was told he was a woman and no brave. He returned to his own camp and told his men that Sioux Jim meant mischief, and in order to prevent another calamity to the tribe, he must be chastised. He again approached the warlike Jim with several warriors at his back. The recalcitrant came out, gun in hand, but the wily chief was too quick for him. He shot and wounded the rebel, whereupon one of his men came forward and killed him. Eastman, Charles A. (1918). Indian Heroes and Great Chieftains. Boston: Little, Brown, and Company.
