Wyoming in the Civil War
Wyoming was not directly affected by the Civil War as regards battles fought in its borders and in the number of soldiers provided.
Wyoming Military Units
No known military units were raised specifically from Wyoming. However men from Wyoming did fight in other units during the Civil War.
The Family History Library and the National Archives have an index to some soldiers from Nebraska Territory (Family History Library films 821905-6).
1890 Census Veterans Schedules
A special census was taken in 1890 of Union veterans of the Civil War. The "Special Schedules of the Eleventh Census (1890) Enumerating Union Veterans and Widows of Union Veterans of the Civil War" (NARA M123) (Family History Library film 338276). An index (Worldcat) to the returns for Wyoming has been published. The records are also available online. For more information on the 1890 Veterans Schedules see Union Census Records.
Compiled Service Records
The Compiled Service Records ($) (Fold3.com) of volunteer Union soldiers who served in organizations from the Nebraska and Dakota Territories are available online. In the future, these records will be made available at no charge through the National Archives web site. The service records are also available at no charge at National Archives research rooms. The compiled service records consist of an envelope containing card abstracts taken from muster rolls, returns, pay vouchers, and other records. Service records may provide rank, unit, date of enlistment, length of service, age, place of birth, and date of death. For more information see Union Service Records.
