The "Dive into History" series brings to life the wealth of fascinating history that lies on the bottom of the sea. The series will appeal to historians, naval enthusiasts and divers as it uncovers many thrilling episodes of our naval past preserved for posterity in the ocean's depths. Volume 3 traces the development of the U-boat and its role in two world wars. The eleven wrecks featured are both war losses and war prizes sunk around the coast of the United States during the twentieth century. The authors are both very experienced divers who have combined their knowledge of the wrecks with detailed historical research to accurately tell the story of the "Raiders of the Deep" which came so close to winning two world wars.Some of the wrecks are within easy reach of the sport diver, while others are far more challenging. Some are largely intact while some have experienced heavy damage. Each story is a microcosm of the tale of the U-boat as a formidable weapon of war. The reader will be surprised by some of the facts uncovered in this book. For instance the presence of a rubber-coated "stealth" U-boat in the Potomac River, only 100 miles from Washington DC. This edition benefits from an addendum that updates the story of the U869, recently identified off the coast of New Jersey.
