"

During the First World War, Somerville College together with the Examination Schools and other Oxford buildings were requisitioned by the War Office to create the Third Southern General Hospital, a facility for the Royal Army Medical Corps to treat military casualties.[1][2] For the duration of the war, Somerville students relocated to Oriel College.[3] Because many male students had left Oxford to enlist in the military, Somerville was able to rent St Mary Hall Quad which they bricked off from the rest of the college to segregate it from the Oriel's remaining male students.[4] Many students and tutors were involved in work in World War I and some of them went to the Western Front in France.
