When in session the Jerseyville City Council adopted a Resolution Of Respect to the former council member. Berthoux was in his last year of a 4 yr. term as city councilman when he volunteered for the draft. Though he had had previous military service and was beyond draft age, Berthoux told friends and associates that he was prompted by a strong feeling of moral obligation to do his part in the Vietnam situation. He enlisted and left for service October 4, 1966. The service man received basic and advanced training at Camp Carson, CO. Following a 30 day leave in August, he left for Vietnam where he was a member of Co. A, First Battalion, 12th Infantry, 4th Infantry Division.
