An interesting read - US reprinting of a British Intelligence pamphlet. One slight problem, though, which the orignial poster does not seem to have noticed - pamphlet is dated 1918, and is thus 20 years out of date...and therefore as much use for WW2 boats as a one-legged man at an arse-kicking party...
