British Conscientious Objectors
Though this website is almost entirely about American C.O.s, the SCPC also holds a small amount of letters and other items by and about WWI British C.O.s. Their experience started in 1914, and their anti-war witness was often shared in American peace circles to help form conscientious principles and responses to war. Because of their influence, it was thought fitting to include them in the mix of voices for this site. To find such, see the Sydney Turner Collected Papers and the letters in the Edward Wilson and Edith J. Wilson Collected Papers.
