Christopher Houston "Kit" Carson (December 24, 1809 - May 23, 1868) was an American frontiersman. The few paying jobs he had during his lifetime included mountain man (fur trapper), wilderness guide, Indian agent, and American 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. In the 1840s, he was hired as a guide by John C. Fremont. Fremont's expedition covered much of California, Oregon, and the Great Basin area. Fremont mapped and wrote reports and commentaries on the Oregon Trail to assist and encourage westward-bound American pioneers. Carson achieved national fame through Fremont's accounts of his expeditions. Under Fremont's command, Carson participated in the uprising against Mexican rule in California at the beginning of the Mexican-American War. Later in the war, Carson was a scout and courier, celebrated for his rescue mission after the Battle of San Pasqual and for his coast-to-coast journey from California to Washington, DC to deliver news of the conflict in California to the U.S. government. During the American Civil War, Carson led a regiment of mostly Hispanic volunteers from New Mexico on the side of the Union at the Battle of Valverde in 1862.-Print ed.
