National Guard muster rolls for 1861 to 1919 can be found at the Colorado State Archives. Service records for the Colorado National Guard from 1861 to 1945 are also located there. The “Index to Compiled Service Records of the Union Army for Colorado” can be found on microfilm at the offices of the Adjutant General. The FHL, Denver Public Library, and National Archives-Rocky Mountain Branch also has that index on file. The recorder’s office or county clerk’s office should have post-World War II soldier discharge papers on file. However, some counties are closing the discharge papers to researchers.

- U.S., Confederate Soldiers Compiled Service Records, 1861-1865 – This database contains an index to compiled service records (CSRs) for soldiers who served with units in the Confederate army. Most of the men whose names appear in this index served with units from 15 different states or territories; others were soldiers raised directly by the Confederate government, generals and staff officers, and other enlisted men not associated with a regiment. Compiled service records are files of cards that abstract original military records relating to an individual soldier. A typical CSR will include an envelope that lists a soldier’s name, rank, unit, and card numbers, followed by cards with details extracted from muster rolls, rosters, hospital rolls, Union prison records, payrolls, and other records, with a new card being created each time a soldier’s name appeared on a new document. The CSRs may also include original documents pertaining to the soldier. The CSRs do not constitute an exhaustive list of all men who served in the Confederate army.
