A look beneath the surface at the lives of the elite force of submariners who served in the Kriegsmarine's U-boat arm during the Second World War.
In the early years of the Second World War, the German submariners known as the Ubootwaffe came perilously close to perfecting the underwater tactics of the First World War and successfully cutting Britain's transatlantic lifeline. To the Allies, these enemy sailors were embarking on a mission that was unequivocally evil.
It was popularly believed that the U-boat men were all volunteers; this was not the case. However, once committed to the Ubootwaffe, each man soon 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 one that he had little chance of surviving. The men of the Ubootwaffe were bound together by an intense camaraderie forged in an environment of ever-present danger, and a unity of purpose more powerful than any known to other sailors.
Grey Wolves captures life on board a U-boat, in text, letters, diaries, journals, memoirs, prose and poetry, relaying tales of the mundane and the routine, dramatic and heroic; the fear and resilience of every crew member, from Kapitainleutnant to Mechaniker. It is a vivid, brutally realistic portrait of the men who fought and died beneath the surface of the Atlantic in what was, perhaps, the most critical battle of the war.
