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.
