The Enormous Room is Cummings’s autobiographical narrative of the time he spent in La Ferté Mace, a French concentration camp a hundred miles west of Paris. Cummings and a friend, both members of an American ambulance corps in France during World War I, were erroneously suspected of treasonable correspondence and were imprisoned from August, 1917, until January, 1918. In this book, Cummings describes the prisoners with whom he shared his captivity, the captors who subjected their victims to enormous cruelty, and the filthy surroundings of the prison camp.
