Grey Wolves (DVD)

This War Archive set of exclusive programs brings the most comprehensive collection of Germany's U-Boat warfare strategies probably ever compiled as a definitive series. The U-Boat success in the North Atlantic almost brought Britain to its knees with its Merchant Navy shipping losses bringing essential raw materials and commodities to continue the war and bring succor to its people. New footage helps us understand the on-going battle between hunter and hunted beneath the cold gray waters of the North Atlantic.
