Replying a little late to Erich's query - one of the best accounts of bomber gunner-vs- Nachtjagd action is a very long chapter in Tom Bennett's book '617 Squadron - The Dambusters At War' detailing in dramatic fashion the actions of Tom McLean DFM, one of the wars' highest-scoring Lancaster gunners.

Bennett was himself a veteran of 617 ; the book, published by PSL in 1986, is something of a misnomer as it deals with 617's post-Dams operations.
