Listed as a Gettysburg Casualty taken to Harrisburg for treatment in one of the Camp Curtin Post Hospitals where he died there July 27, 1863.

There is an outside chance that there may be some information on him in the medical records of the Camp Curtin hospitals. Perhaps in the Camp Curtin Ledger, 1863-1865 held in the Civil War Holdings of the Pennsylvania State Archives, Harrisburg, PA
