Dear Ms. Doyle,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the series Carded Records Showing Military Service of Soldiers Who Fought in Volunteer Organizations During the American Civil War in the Records of the Adjutant General's Office, 1762 - 1917 (Record Group 94). For more information about these records, please contact the National Archives at College Park - Textual Reference (RDT2) via email at Archives2reference@nara.gov.
Many of the service records in this series have been made available via microfilm and through digitization of the microfilm. Unfortunately, the records for Indiana Volunteers have not been microfilmed or digitized. To request a copy of his non-digitized service record, please download the NATF Form 86, fill it out to the best of your knowledge, and mail the completed forms to the address listed on the form. For more information see Requesting Copies of Older (pre-WWI) Military Service Records.
The majority of Civil War pension files in the Records of the Department of Veterans Affairs (Record Group 15) are in the custody of the National Archives at Washington, DC - Textual Reference (RDT1). To request a search and order copies of military pension application files based on Union service during the Civil War, please complete a NATF Form 85 and mail it to the address on the form.
There are also 3 record series (XC files) in Record Group 15 at the National Archives at St. Louis (RL-SL) that include claims files relating to Civil War Veterans. These records were transferred to the National Archives in 1952 and 1955 from the VA. Please email both RDT1 at Archives1reference@nara.gov and RL-SL at firstname.lastname@example.org with full details about the file you are seeking.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RDT1 and RL-SL. Also, please note that NARA has suspended reproduction and digitization services until further notice due to COVID-19. Orders will not be serviced until operations can resume safely. Once operations resume, document reproduction requests will be filled in the order in which they were received. Additionally, NARA has suspended the option to submit orders online using eservices.archives.gov. We apologize for any inconvenience.
