Native American Mounted Rifleman, 1861-65 is one of the titles in Osprey Publishing's Warriors series. All titles in the series are well-researched and contain full-colour plates of the uniforms or clothing worn by military forces of the past and present. In this title, the author and illustrator focus on the Aboriginal People of the Southeast cultural region. The Five Civilized Tribes (Cherokee, Chickasaw, Choctaw, Creek, Seminole) were caught up in the turmoil of the American Civil War and they had no choice but to side with the Confederacy. This volume focuses on their war efforts during this time period.
