THYBORØN, DENMARK—CBS News reports that researchers from the Sea War Museum Jutland have found the wreckage of U-3523, a Nazi submarine sunk by a British aerial assault on May 6, 1945, the day after Nazi forces surrendered in Denmark. The extremely quiet Type XXI vessel was said to have been capable of travel from Europe to South America without surfacing. Historic records indicate the U-3523 had been carrying a crew of 58, but its mission is unknown. The submarine was found in the North Sea, about nine miles from the site where the British navy reported the hit, partially buried in the sea bed on a diagonal. The researchers have documented more than 450 wrecks while scanning the areas of the North Sea and the Skagerrak strait, which flows between Denmark and Norway. Nine of those wrecks have been identified as German submarines. To read more, go to "The Archaeology of World War II."
