HMS Affray was the last RN submarine to be lost at sea. At the time of her sinking, rumours about the cause of her loss circulated widely. Many were discounted once her final resting place had been found and the Official Inquiry's report had been published. However, speculation persists to this day as to the reasons why she sank.
From Twenty Thousand Leagues Under the Sea to The Hunt for Red October, readers the world over have demonstrated an enduring fascination with travel under the sea. Yet the riveting story behind the invention of the submarine—an epic saga of genius, persistence, ruthlessness, and deceit—is almost completely unknown.
Like Henry Ford and the Wright brothers, John Philip Holland was completely self-taught, a brilliant man raised in humble circumstances, earning his living as a schoolteacher and choirmaster. But all the while he was obsessed with creating a machine that could successfully cruise beneath the waves. His struggle to unlock the mystery behind controlled undersea navigation would take three decades, during which he endured skepticism, disappointment, and betrayal. But his indestructible belief in himself and his ideas led him to finally succeed where so many others had failed.
Going Deep is a vivid chronicle of the fierce battles not only under the water, but also in the back rooms of Wall Street and the committee rooms of Congress. A rousing adventure at its heart—surrounded by an atmosphere of corruption and greed—this a story of bravery, passion, and the unbreakable determination to succeed against long odds.
