For some time he held out, but the rapid disappearance of the buffalo, their only means of support, probably weighed with him more than any other influence. In July, 1877, he was finally prevailed upon to come in to Fort Robinson, Nebraska, with several thousand Indians, most of them Ogallala and Minneconwoju Sioux, on the distinct understanding that the government would hear and adjust their grievances. At this juncture General Crook proclaimed Spotted Tail, who had rendered much valuable service to the army, head chief of the Sioux, which was resented by many. The attention paid Crazy Horse was offensive to Spotted Tail and the Indian scouts, who planned a conspiracy against him. They reported to General Crook that the young chief would murder him at the next council, and stampede the Sioux into another war. He was urged not to attend the council and did not, but sent another officer to represent him. Meanwhile the friends of Crazy Horse discovered the plot and told him of it. His reply was, “Only cowards are murderers.” His wife was critically ill at the time, and he decided to take her to her parents at Spotted Tail agency, whereupon his enemies circulated the story that he had fled, and a party of scouts was sent after him. They overtook him riding with his wife and one other but did not undertake to arrest him, and after he had left the sick woman with her people he went to call on Captain Lea, the agent for the Brules, accompanied by all the warriors of the Minneconwoju band. This volunteer escort made an imposing appearance on horseback, shouting and singing, and in the words of Captain Lea himself and the missionary, the Reverend Mr. Cleveland, the situation was extremely critical. Indeed, the scouts who had followed Crazy Horse from Red Cloud agency were advised not to show themselves, as some of the warriors had urged that they be taken out and horsewhipped publicly. Under these circumstances Crazy Horse again showed his masterful spirit by holding these young men in check. He said to them in his quiet way: “It is well to be brave in the field of battle; it is cowardly to display bravery against one’s own tribesmen. These scouts have been compelled to do what they did; they are no better than servants of the white officers. I came here on a peaceful errand.” The captain urged him to report at army headquarters to explain himself and correct false rumors, and on his giving consent, furnished him with a wagon and escort. It has been said that he went back under arrest, but this is untrue. Indians have boasted that they had a hand in bringing him in, but their stories are without foundation. He went of his own accord, either suspecting no treachery or determined to defy it.
