Biography
Percy H. Peters was a Church of the Brethren conscientious objector from Virginia imprisoned during World War I. Court-martialed for refusing military service, he was held at Fort Leavenworth. (Documented in the Swarthmore College Peace Collection's World War I Conscientious Objectors database.)
Custody record
The cited World War I archival record does not establish a one-day imprisonment. The imposed sentence and the period actually spent in custody are different; no exact duration is recorded here unless supported by custody records.
Moomaw describes Percy H. Peters in a Camp Lee guardhouse from April 15 to June 15 and sent to Leavenworth on July 16. The separate Greenleaf account of Roy E. Peters must not be assigned to Percy; the precise release remains unresolved.
The compilation explicitly reports a ten-year hard-labor sentence imposed August 29, 1918. Its account distinguishes military discharge in January 1919 from an earlier release from Leavenworth and transfer to Camp Dodge; the imposed ten years is not actual service.
