Excellent book, very thoughtful and raises some interesting questions - not too much naval but if you're interested in the end of the war and the demise of the Third Reich (I'm an Endkampf nut), it's an absolute must.
Good book but wrong Kershaw! Robert Kershaw's the man behind It Never Snows - he's an ex-Para officer from memory who spent a lot of time in Germany. You generally can't go wrong with his books - always a good read. Personally, I prefer War Without Garlands, but then the Eastern Front is my specialist subject.
