After returning from Washington, White Antelope became known not as a warrior, but as an advocate of peace between white Americans and the native tribes living on the Great Plains. By the late 1850s, many white Americans were no longer willing to follow past treaties that had been signed with the Cheyenne about their land, as gold had been found there, and they resolved to renegotiate the terms. White Antelope was reportedly involved in the ensuing negotiations, and his name is signed to the 1861 Treaty of Fort Wise that emerged, relegating the Cheyenne to a small reservation. White Antelope later condemned the treaty as a "swindle", saying that his name had been added to the Treaty without his consent. In the 1860s he again visited Washington, meeting with Abraham Lincoln.
