"From the heart-rending account of the sinking of the German liner Wilhelm Gustloff in 1945 - the worst maritime disaster in world history - through to a variety of other brutal actions carried out by numerous submarine commanders, including the sinking of the hospital ship Centaur in 1943, this book comes from the deep shadows of a tragic past to reveal the terrible truth of a secretive war that was responsible for the deaths of unimaginable numbers of innocent people. Discover how merchant seamen were savagely machine-gunned in the water, callously slaughtered with hand-grenades or simply left to the circling sharks. Elsewhere, hundreds of doctors, nurses, ship's crew, ambulance drivers and hospital orderlies were viciously killed without compassion, despite being protected by the Geneva Convention."--Provided by the publisher.
