Grey Wolves 1939-1941 (DVD)

September 1939 found the submarine arm of the Kriegsmarine unready for conflict. Nevertheless, Doenitz's 'Grey Wolves' were still able to inflict substantial losses on vessels carrying Britain's lifeblood. This program depicts the course of the U-boat war in its initial phase in vivid images captured primarily by German cameramen with much being presented to the viewer for the first time.
