Dear Mr. Boltz,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the Court Martial Case Files, 12/1800 - 10/1894 in the Records of the Office of the Judge Advocate General (Army) (Record Group 153) that may include the court of inquiry information you seek. Click on “Search within this series” to search for specific cases. There also may be related records in one or more of these 16 series in the Records of the Office of the Inspector General (Army) (Record Group 159) for the 1860s. Please email National Archives at Washington, DC - Textual Reference (RDT1) at Archives1reference@nara.gov for more information about these records or assistance with locating a specific case.
In addition, we located Ohio Civil War Central’s page on the 111th Regiment Ohio Volunteer Infantry (1862 - 1865) that includes a report from the regimental commander mentioning the incident.
We hope this is helpful. Best of luck with your research!
