The Harry Ransom Center, the distinguished humanities research library and museum at the University of Texas at Austin, is preparing an exhibition in 2014 to mark the centenary of World War I. The exhibition will view the conflict from the point of view of its soldiers through letters, diaries, memoirs, poems, novels, photographs, propaganda posters, films, and avant-garde art. For Memorial Day, the center has given The Daily Beast exclusive final dispatches from three English literary heroes who died during the war: poet Wilfred Owen’s last letter to his mother, Roland Gerard Garvin’s last letter to his father, Observer editor James Louis Garvin, and poet Edward Thomas’s last letter to his best friend, writer Edward Garnett.
