The Rough Riders is the name bestowed on the 1st United States Volunteer Cavalry, one of three such regiments raised in 1898 for the Spanish–American War and the only one of the three to see action. The United States Army was small and understaffed in comparison to its status during the American Civil War roughly thirty years prior. As a measure towards rectifying this situation President William McKinley called upon 1,250 volunteers to assist in the war efforts.
