Ernest Hemingway’s third novel, A Farewell to Arms (1929), was crafted from his earliest experience with war. As a teenager just out of high school, Hemingway volunteered to fight in the First World War but was rejected because of poor eyesight. Instead, he drove a Red Cross ambulance on the Italian front, where he was wounded in 1918 by a mortar shell. While recovering in a hospital, Hemingway fell in love with Agnes von Kurowsky, a nurse seven years his senior.
