Excellent ending to Dr. Rodger's three book series "A Naval History of Britain", with the same level of detail and interesting presentation of facts I have come to expect from reading other of his works over the years. For anyone interested in a comprehensive naval history of Britain (from which the US Navy inherited much of its tradition), I would highly recommend this series. In addition, "The Wooden World: An Anatomy of the Georgian Navy" is also quite a good read. My (incomplete, sadly) collection of Dr. Rodger's works will continue to hold a special place on my naval history shelf for easy reference in the future. I also hope Dr. Rodger's health has improved. The shipper unfortunately did not pack this book well, resulting in minor damage (mostly cosmetic - book is still entirely readable).

Answers Many Questions about Naval Developments

Format: Hardcover

The history offers a detailed and well organized account of the Royal Navy as it transitioned from sail to steam. Coverage included personalities, technology, tactics and strategy. The combination provided a complete appreciation of the dynamics at play, some unexpectedly. The details might be a bit much for a casual reader but offered plenty of avenues for research not available or compiled in one source. I look forward to the final volume, which should describe another watershed era.

Great Book with a different perspective

Format: Hardcover

This will be a short review of a very long book. I ordered the book expecting more of a history of the British Navy, but this is more of a history of Britain with respect to its navy. It is still excellent and authoritative, just different than I expected. I really appreciate a somewhat different perspective than I have found in some other books. For example, any discussion of Jackie Fisher I have read previously seemed to border on the hagiographic, whereas here he seems to get a very evenhanded appraisal. A great book, highly recommended.
