The Richmond Sixteen were a group of "absolutist" British conscientious objectors during the First World War. Conscripted into the British Army in 1916, they refused to undertake even non-combatant military duties. Brought together at Richmond Castle, Yorkshire, most not knowing each other previously, they were transported to France, where they were court-martialled and formally sentenced to be executed by firing squad, but this sentence was immediately commuted to ten years' penal servitude. They were released in April 1919, several months after the Armistice of 11 November 1918 and a few weeks before the signing of the Treaty of Versailles.
