Grey Wolves: The U-Boat War 1939–1945

In the early years of the Second World War, the elite force of German submariners known as the Ubootwaffe came perilously close to perfecting the underwater battle tactics and successfully cutting Britain's transatlantic lifeline. To the Allies, these enemy sailors were embarking on a mission of unequivocal evil.Each member of the Ubootwaffe understood that he must take pride in being part of a unique brotherhood. He had to do so because he was setting out—in claustrophobic, unsanitary, stench-filled, and ultimately hellish conditions—on a journey that would test his mental and physical endurance to the very limits, and which he had little chance of surviving. Those that did return soon ceased to take comfort in friends or family, dwelling only on the knowledge that another patrol awaited them.
