Christopher Houston Carson (December 24, 1809 - May 23, 1868), better known as Kit Carson, was an American frontiersman. He was a mountain man (fur trapper), wilderness guide, Indian agent, and U.S. Army officer. Carson became a frontier legend in his own lifetime via biographies and news articles. Exaggerated versions of his exploits were the subject of dime novels.

Carson wanted to take a winter break from the campaign. Major General Carleton refused. Kit was ordered to invade the Canyon de Chelly. It was here that many Navajos had taken refuge. Historian David Roberts writes, "Carson's sweep through the Canyon de Chelly in the winter of 1863-1864 would prove to be the decisive action in the Campaign."  The Canyon de Chelly was a sacred place for the Navajo. They believed that it would now be their strongest sanctuary. Three hundred Navajo took refuge on the canyon rim at a place called Fortress Rock. They resisted Carson's invasion by building rope ladders and bridges, lowering water pots into a stream, and keeping quiet and out of sight. These three hundred Navajo survived the invasion. In January 1864, Carson swept through the 35-mile (56 km) Canyon with his forces. The thousands of peach trees in the canyon were cut down. Few Navajo were killed or captured. Carson's invasion, however, proved to the Navajo that the United States could invade their country at any time. Many Navajo surrendered at Fort Canby.  By March 1864, there were 3,000 refugees 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 Long Walk of the Navajo. 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.Answer this question using a quote from the following article:
