Biography
Roy E. Peters was a Church of the Brethren conscientious objector from Illinois imprisoned during World War I. His first-person account describes guarded custody beginning May 15, 1918, and confinement at Fort Leavenworth from September 22 to November 25, 1918. He signed his conscientious-objector discharge on January 17, 1919, after leaving the prison.
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.
In his first-person account in Christianity Versus War, Roy E. Peters (military number 753170; Leavenworth number 14589) dates his guardhouse arrest to May 15, 1918. He remained under guard during hospital treatment, reached Leavenworth on September 22, and left that prison on November 25, 1918. His January 17, 1919 conscientious-objector discharge was a later military-administrative event, not the Leavenworth release.
