Dear Ms. Wise,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located Carded Records Showing Military Service of Soldiers Who Fought in Confederate Organizations in the War Department Collection of Confederate Records (Record Group 109). Portions of this series have been digitized and are available online. We were unable to locate any results for “Bithan” or “Bithon” or “Mississippi Grays” in the digitized records. We located some results for "Lee, b" "Mississippi."
To order records that have not already been digitized, please fill out a NATF Form 86 for the service records and mail the completed forms to the address listed on the form. You also may place your order online using eservices.archives.gov. For more information see Requesting Copies of Older (pre-WWI) Military Service Records.
Please note that the National Archives and Records Administration (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.
We also located a series titled Record Books of Executive, Legislative, and Judicial Offices of the Confederate Government in Record Group 109 that contains “Records of Mississippi Troops” including morning reports, company books, and hospital registers. For access to these records, please contact the National Archives at Washington, DC - Textual Reference (RDT1) via email at email@example.com.
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. We apologize for this inconvenience and appreciate your understanding and patience.
We hope this is helpful. Best of luck with your research!
