The history of the development of submarines covered in this book spans the most tumultuous years of the 20th century. When the little Holland No. 1 was launched in 1901, few could guess that the submarine would become the most potent weapon of war ever developed.

Royal Navy submarine HMS Poseidon sank in collision with a freighter during routine exercises in 1931 off the Chinese coast. Thirty of its fifty-six-man crew scrambled out of the hatches as it went down. Of the twenty-six who remained inside, eight attempted to surface using an early form of diving equipment: five of them made it safely to the surface in the first escape of this kind in submarine history and became heroes. The incident was then forgotten, eclipsed by the greater drama that followed in World War II, until news emerged that, for obscure reasons, the Chinese government had salvaged the wrecked submarine in 1972. This lively account of the Poseidon incident tells the story of the accident and its aftermath, and of the author’s own quest to discover the shipwreck and its hidden history.

Richard Hammond offers a major reassessment of the role of the war at sea in Allied victory in the Mediterranean region.

A fascinating and comprehensive account of how an initially ineffectual underwater boat—originally derided and loathed in equal measure—evolved into the most powerful and terrifying vessel ever invented—with enough destructive power to end all life on Earth. Iain Ballantyne considers the key episodes of submarine warfare and vividly describes the stories of brave individuals who have risked their lives under the sea, often with fatal consequences. His analysis of underwater conflict begins with Archimedes discovering the Principle of Buoyancy. Our clandestine journey then moves through the centuries and focuses on prolific characters with deathly motives, including David Bushnell, who in 1775 in America devised the first combat submarine with the idea of attacking the British. Today, nuclear-powered submarines are among the most complex, costly ships in existence. Armed with nuclear weapons, they have the ability to destroy millions of lives: they are the most powerful warships ever created. At the heart of this thrilling narrative lurks danger and power as we discover warfare’s murkiest secrets.

Submariners are a tight knit group of men bound together by training and experience, and with a language all their own. That language is perhaps a little vulgar, but never intentionally demeaning, and a little irreverent but still worldly. This work is an attempt to preserve and explain some of these curious guys who so proudly wear a shiny metal pin that looks like a strange pair of fish on their left breast. This process of accumulating this new language begins in Boot Camp, and is added to with every change of duty station the sailor undergoes. It is heard aboard the boats and, unknowingly, by family members who can't understand terms like head, deck, and overhead, and who think SOS is a distress signal.

The biography of Hans Rose, Germany's most successful WWI convoy period U-boat Ace and WWII anti-fascist naval officer. 'He was a brave man who would take chances that most of his compatriots would avoid. He played his desperate game with a certain decency.'
