Dear Ms. Alex,
Thank you for posting your request on History Hub!
We suggest that you request a copy of his Official Military Personnel File (OMPF). OMPFs and individual medical reports for enlisted men of the U.S. Army who were separated from the service after October 1912 and prior to 1958 are in the custody of NARA's National Personnel Records Center in St. Louis. In many cases where personnel records were destroyed in the 1973 fire, proof of service can be provided from other records such as morning reports, payrolls, and military orders, and a certificate of military service will be issued. Please complete a GSA Standard Form 180 and mail it to NARA's National Personnel Records Center, (Military Personnel Records), 1 Archives Drive, St. Louis, MO 63138-1002. You also may fax the form to 314-801-9195. Veterans and their next of kin also may use eVetRecs to request records. See eVetRecs Help for instructions. For more information see Official Military Personnel Files (OMPF), Archival Records Requests.
You also may check the Hospital Admission Card Files contained in the Records of the Office of the Surgeon General (Army) (Record Group 112) located at the National Archives at College Park. For information on access to this series, please contact Electronic Records (RDE) at email@example.com.
In addition, we searched the National Archives Catalog and were able to locate his name listed on the World War II Honor List of Dead and Missing Army and Army Air Forces Personnel from Virginia, 1946 in the Records of the Adjutant’s General Office, 1917-1985 (Record Group 407). A ‘Thomas Pettit’ with matching serial number is listed as ‘KIA’ at the rank of Corporal under ‘Accomac’ county. This list is digitized and available for viewing using the Catalog.
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 RDE. Also, the National Personnel Records Center is is currently only servicing emergency requests and will soon expand its service to include time-sensitive requests from veterans for records needed to secure VA home loan guarantees and employment opportunities. We apologize for this inconvenience and appreciate your understanding and patience.
We hope this is helpful. Best of luck with your family research!
