Wilfred Owen
Conditions for troops on the Western Front were very harsh, and Owen suffered several bad experiences that led to him being considered unfit to continue fighting.  He was sent to Craiglockhart War Hospital in Edinburgh for treatment by a psychiatrist.  While there, he wrote poetry, and became editor of the hospital magazine, which was called The Hydra.  Soon afterwards, a better-known poet called Siegfried Sassoon arrived at the hospital as a patient, and the two became great friends.  Sassoon helped Owen to improve his writing, and introduced him to other writers and publishers.  Although Sassoon had made a public protest against the war, he quickly grew tired of life at the hospital, and went back to France to continue fighting.  In the meantime, Owen was given a job in the Northern Command Depot at Ripon, where he did not have to do any fighting.
