Grey Wolves

This is the tragic story of the U-boats at war. Brave men fighting a losing battle against odds they could never hope to overcome. Out-numbered, out-gunned and out-thought, the U-boats were justifiably known to their crews as 'iron coffins'. Somehow the U-boat fleet rose to the challenge and even managed a brief flicker of success before their inevitable fate enveloped them. The U-boat war encompassed a campaign that began on the first day of the European war and lasted for six years, involved thousands of ships and stretched over thousands of square miles of ocean, in more than 100 convoy battles and perhaps 1,000 single-ship encounters. In the 68 months of World War II, 2,775 Allied merchant ships were sunk for the loss of 781 U-boats. This is the story of that massive encounter from the German perspective.
