From its title, this book purports to be about the Royal Navy, but only a minority of the text is devoted to that service. There is no mention of it at all until page 34 (Out of 144 pages total, or roughly almost 25% of the way through the book), where the fate of some submarines sent to the Baltic in 1915 is covered in one paragraph. The Royal Navy then does not re-appear until page 46. While some Royal Navy ships, primarily light cruisers, destroyers, torpedo boats and submarines, were involved in the fighting in this area during the post war period, the part they played was small, usually only involved a few ships and would only merit a footnote in most histories. One interesting aspect is that the HMS Vindictive, a cruiser converted with a “flying off deck” was deployed to the area and some RNAS aircraft, albeit flying from land bases, were used in bombing attacks against ships and shore targets.
