Tim O'Brien was drafted to serve in the Vietnam War after graduating from college in 1968. He saw combat in Vietnam from 1969-1970 and was wounded near My Lai. His experiences in the war had a significant impact on him and shaped his writing. In his novels and stories, O'Brien explores themes of violence, courage, and the reality of combat by drawing on his own memories of serving in Vietnam. Many of his works, like The Things They Carried, blend fact and fiction as O'Brien seeks to describe and understand his experience in the war through writing.
