Perhaps the most important victory won by the allies in the West was the triumph over the deadly German U-boat. Once a harbinger of death for merchant shipping and its escorts, by 1943 the British and American fleets had gained the upper hand and the U-boat had become the hunted rather than the hunter. This film features extensive footage from the Battle of the Atlantic, and of U-534 the last surviving U-Boat in Western Europe. She was sunk in the Baltic in 1945 and raised again to the surface intact in 1993. On board U-534 the treasures of World War II were preserved as if in aspic. Now for the first time in over 50 years we can experience again the claustrophobic world of the U-boats.
