Getting back to what was, rather than what might or shouldn't have been, I've just finished the Bercuson/Herwig
Bismarck book.
All in all, not a bad 'starter' read on the subject, with only two irritating points ; the author constantly starts sentences with 'As well,...' and also tries to make much of a case that the USA was heavily involved in the chase (but then, it was originally published in the USA and obviously needed selling to the publishers...).
But it is a very dramatic story, truly fascinating, and could indeed be the starting point for dozens of 'what ifs'. The book has a good bibliography, and I'm fairly certain to be doing a bit more in-depth reading.
And I'm still wondering how
Bismarck failed to shoot down a single Swordfish.....
