Many foundational books of the American and English canon of the 20th century were composed by writers who fought in wars and brought it back in fantasy as a warning. C.S Lewis and Tolkien fought in World War 1. Orwell fought in the Spanish Civil War while Hemingway reported on it, William Golding ("Lord of the Flies") served in the Royal Navy during World War 2, and Vonnegut was a prisoner of war in Dresden which he described in Slaughterhouse-Five. #bookstr
