Lost Treasure Ships of The Twentieth Century contains intriguing stories of lost treasure, dramatic sinkings, heroic feats of survival and technically sophisticated salvage. Some of the treasures have already been found and recovered but some are still awaiting discovery. This book will appeal to both the practical diving aficionado and the armchair dreamer, as well as the large number of enthusiasts who are interested in all aspects of maritime history, particularly relating to the two World Wars. The locations of about 170 lost treasure ships, such as the Titanic and the Laurentic, with their valuable cargoes are shown on detailed maps along with the major routes which were used for the movement of gold and treasure around the world. Nigel Pickford also explores the sophisticated salvage operations which make use of such technologically advanced equipment as computer controlled side scan sonar systems and deep sea grabs as well as featuring historic feats of diver centred salvage.
