As one can surmise from the title, the following book is a biography of a man named Kit Carson. He was an American frontiersman, a fur trapper, wilderness guide, Indian agent, and U.S. Army officer. He became a frontier legend in his own lifetime by biographies and news articles, and exaggerated versions of his exploits were the subject of dime novels. His understated nature belied confirmed reports of his fearlessness, combat skills, tenacity, and profound effect on the westward expansion of the United States.
