Crazy Horse's arrest

Crazy Horse ran into issues during negotiations with both the Army and his other tribesmen. Crazy Horse resisted Clark's attempts to persuade him to travel to Washington, which strengthened the Army's view that he was too unpredictable for negotiations.

Following a rumor that Crazy Horse had gained favor with white people and that they intended to appoint him as the leader of all Sioux, several Sioux became agitated with one another.

As the Army sought Crazy Horse's assistance in their struggle with the Nez Perce people, tensions grew. Untrue to what Crazy Horse had said, an interpreter during these meetings asserted that Crazy Horse had made a vow to continue fighting until all white men were dead.

To combat the Nez Perce warriors, several Sioux warriors enlisted in the Army. Crazy Horse became angry and threatened to leave the negotiations. He was then promptly detained.
