Any recommendations for fictional accounts of WWl or WWll?

I have read “All Quiet on the Western Front ” and “Slaughterhouse 5”. I think that literature can get to the heart of personal experience by making an historical event personal and help us to understand it better than busloads of books about battle strategies and so on. I’m not discounting the value and need for those also, just looking for powerful literary accounts.

The best novel about WWl I have ever read was “Birdsong:A Novel of Love and War” by Sebastian Faulks. It was an enormous bestseller in the UK but is not as well known here in the United States. It takes you right into the trenches and you see the war through the eyes of a soldier. That novel made me appreciate what those men went through in a way I never had before. That is the sort of book I am looking for.
