Peter Henn's "The Last Battle" maybe. The author served with fighter units but went on to the Schlachtflieger after wounds left him unfit for high altitude flying. It's written under a pseudonym but there was discussion here years ago about his real identity (although I can't remember what the answer was). And of course there was Hans-Ulrich Rudel (if you can stomach his unrepentant political attitudes).
