16,000 men registered as conscientious objectors during the First World War. 3,400 joined the Royal Army Medical Corps, or the Non-Combatant Corps, dubbed the ‘No Courage Corps’. 6,312 conscientious objectors were arrested; 5,970 faced a court martial - and most were imprisoned. 81 conscientious objectors died, and others had mental breakdowns, due to their harsh treatment in prisons and work camps. Many continued to be ostracised after the war, even by their churches. Here are some of their stories.
