Organizing as the United Indians of All Tribes Foundation (UIATF) with Whitebear as executive director, the Indians used tactics ranging from politicking to occupation of land to celebrity appearances to gain more support. For three months, activists engaged in what Whitebear later described as "Invasion, arrests, jailings, letters of expulsion from military property, physical escort off the fort, re-invasion." The Army cordoned off the fort with concertina wire, brought in two companies of troops from Fort Lewis to prevent incursions, and dug foxholes.
