How Carriers Fought : Carrier Operations in WWII
..an engaging and informative work that helps deliver clarity to a topic that is still far more commonly asserted and assumed than it is understood. * Vulcan: The International Journal of the History of Military Technology * This is a great book for the general reader and the naval expert but also for the naval wargamer who needs the detail for his games; thoroughly recommended. * Miniature Wargames * This book is thoroughly recommended. It inspired all kinds of ideas and reflections whilst also being worthwhile simply as a reminder of the importance of tactical and technical detail for a fully rounded appreciation of why the Pacific War turned out the way it did. [...] Whether you are primarily a war-gaming enthusiast or a historian of operations and strategy, there is much here for you. * Naval Review *
