Watch The Grey Wolves: Echoes from WWII Online

Grey Wolves captures life on board a U-boat, from the German perspective. First hand accounts in text, letters, diaries, journals, memoirs, 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.
