Nazi Underworld: The Ghost Of U-513

On the 19th of July 1943, a US patrol plane spots a German U-boat on the water surface. There is no time for the vessel to dive: 2 bombs are direct hits. The U-boat is U-513. It takes 46 of its crew to their deaths - only 7 men survive. But until now, the final resting place of U-513 and what exactly happened to it has remained a mystery. The adventurer Vilfredo Schurmann made it his mission to find the submarine off the Brazilian coast and in the summer of 2011 finally struck gold: followed by our cameras, he managed to locate the wreck. It allows us to piece together the puzzle of the U-boat's final mission and grizzly end.
