A highly readable account covering the technology, politics, personalities and events which shaped the Royal Navy submarine service.
The personal testimony of numerous submariners brings home the bravery of the men who put to sea in these craft, and the tragedy that befell so many, particularly in the first half of the 20th century.
The technological progress from Britain's first Holland type submarines of 1901 (20m long, 120 tonnes) to the latest high-tech Trident vessels (150m long, 16,000 tonnes) is fascinating in itself.
This book has something to offer anyone interested in WW1, WW2, cold war or naval history.
