Camp Wardwell was established in 1865 along the Overland Trail to protect emigrants and supplies going to and from Denver and the mining districts. The fort was renamed in 1866 by General John Pope for one of his staff, Colonel Christopher A. Morgan, who had died earlier that year. The fort closed in 1868 after being used by 19 different companies from 11 cavalry and infantry regiments (about 1,300 soldiers).
