The Civilian Public Service (CPS) was a program of the United States government that provided conscientious objectors with an alternative to military service during World War II. From 1941 to 1947, nearly 12,000 draftees, willing to serve their country in some capacity but unwilling to perform any type of military service, accepted assignments in "work of national importance" in 152 CPS camps throughout the United States and Puerto Rico. Draftees from the historic peace churches and other faiths worked in areas such as soil conservation, forestry, fire fighting, agriculture, under the supervision of such agencies as the U.S. Forest Service, the Soil Conservation Service, and the National Park Service. Others helped provide social services and mental health services. The CPS men served without wages and minimal support from the federal government. The cost of maintaining the CPS camps and providing for the needs of the men was the responsibility of their congregations and families. CPS men served longer than regular draftees and were not released until well after the end of the war. Initially skeptical of the program, government agencies learned to appreciate the men's service and requested more workers from the program. CPS made significant contributions to forest fire prevention, erosion and flood control, medical science and reform of the mental health system. Background Conscientious objectors (COs) refuse to participate in military service because of belief or religious training. During wartime, this stance conflicts with conscription efforts. Those willing to accept non-combatant roles, such as medical personnel, are accommodated. There are few legal options for draftees who cannot cooperate with the military in any way. Experiences of World War I The conscription law of World War I provided for noncombatant service for members of a religious organization whose members were forbidden from participating in war of any form. This exemption effectively limited conscientious objector status to members of the historic peace churches: Mennonites (and other Anabaptist groups such as Hutterites), Religious Society of Friends (Quakers) and Church of the Brethren. The law gave the President authority to assign such draftees to any noncombatant military role. Conscientious objectors who refused noncombatant service during World War I were imprisoned in military facilities such as Fort Lewis (Washington), Alcatraz Island (California) and Fort Leavenworth (Kansas). The government assumed that COs could be converted into soldiers once they were exposed to life in their assigned military camps. Simultaneously the Justice Department was preparing
