The Brits had subs?:rotfl:
No, really, there are almost certainly many good books about British submarine operations during the war; but one I would recommend you hunt down is
War Beneath The Sea, by Peter Padfield. It gives a great overview of ALL sub ops by all nations; and all the sections are equally good.
