Hemingway is my absolute favorite author and A Farewell to Arms is absolutely stunning. A lot of people have trouble reading Hemingway, he leaves a lot up for interpretation and discussion but this is just part of his genius. As for symbols, this SparkNotes page is lacking severely. Some big ones are touched on but read carefully and read it a few times keeping in mind that each word has a purpose. Scene descriptions are not put in there for entertainment, the weather, the trees, the mountains, each description keys in to another aspect of the novel.
