Hitler's Secret Attack On AmericaMay 21, 2017

On December 11, 1941, Hitler declares war against America. For German Admiral Karl Donitz, Commander of the U-boat submarine fleet, the time is at hand. Donitz devises a plan for a surprise attack on the US Atlantic Seaboard, called ‘Operation Drumbeat‘. The story of one of the most deadly attacks off America's East Coast is covered up and remains largely untold and secreted away - until now. For the first time, the story of these U-boats and their prey is being hunted down, uncovered and filmed. Using advanced HD remote operated vehicles, side scan sonar, and 3D imaging, this show pieces together the tactics, battles, heroes and villains of ’Operation Drumbeat’, one of the least known and deadliest attacks on the US in history.
