The American officer's love for an English nurse is the romantic part of the story that adds to its charm. Although the characters and plot of the story are not real, they are all reflections of the author's personal experience of being on the war front. The detailed and vivid descriptions that the author provides of the war front, hospitals, and the situation of the soldiers have added to the value of this book.
The brutality of war and of course its futility compared to the sacrifices it brings are among the other beliefs that the author expresses in the margins of his story. If you are interested in reading stories that are influenced by a particular historical event, reading the book "A Farewell to Arms" will not be without pleasure.
