Biography
Joseph J. Jantz was a Mennonite conscientious objector from Oklahoma imprisoned during World War I. Court-martialed for refusing military service, he was held at Fort Leavenworth. Sentenced to 25 years in prison. (Documented in the Swarthmore College Peace Collection's World War I Conscientious Objectors database.) Archival note: sent to Camp Travis & assigned to 57th Co., 165th Depot Brigade; put in CO detachment; one of the 41 COs court-martialed at Ft. Travis for refusing to wear the uniform; sentenced to 25 years in 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.
The June 15, 1918 release entry requires confirmation: an indexed roster dated November 27, 1918 lists Joseph J. Jantz, prisoner 13173. The original roster context and final discharge still need verification.
