By March 1864, there were 3,000 refuges at Fort Canby. An additional 5,000 arrived in the camp. They were suffering from the intense cold and hunger. Carson asked for supplies to feed and clothe them. The thousands of Navajo were led to Bosque Redondo. Many died along the way. Stragglers in the rear were shot and killed. In Navajo history, this horrific trek is known as The Long Walk. By 1866, reports indicated that Bosque Redondo was a complete failure. Major Carleton was fired. Congress started investigations. In 1868, a treaty was signed, and the Navajo were allowed to return to their homeland. Bosque Redondo was closed.
