Special Collections & Archives has several books containing lists of Ohio soldiers who served in the Revolutionary War, War of 1812, Mexican War, Civil War, and Spanish-American War. Check the library catalog for these sources, available for use in our reading room.
For all servicemen who enlisted from Ohio since World War I and all National Guardsmen (since 1903), the records are located in the Veterans' Affairs Division, Office of the Adjutant General. Ohio did not grant state pensions. For U.S. Regular Army officers, 1789-1917, and enlisted men, 1789-1912, the records are kept by the National Archives and Records Administration. Later records are kept by the National Personnel Record Center.
