For the first time in history, National Geographic and a group of scientists search the ocean floor for a series of shipwrecks many Americans never heard about. Everyone knows that on December 7, 1941, the Japanese attacked Pearl Harbor. But what most dont know is just days later, Hitler sent his own force to devastate the East Coast. On December 19, the German Naval War Staff sent three U-boats to American waters. It was an assault so deadly, it was covered up by the U.S. government. 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 U.S. Atlantic Seaboard, called “Operation Drumbeat”. The message to the United States is clear; Hitler is coming… This story, one of the most deadly attacks off America's East Coast, is covered up and remains largely untold and secreted away for over 60 years –until now. For the first time, the story of these U-boats and their prey is being hunted down, uncovered and filmed by NOAA National Marine Sanctuaries. Using advanced Hi-Def ROV's, side scan sonar, and 3D imaging, this show will piece together the tactics, battles, heroes & villains of, “Operation Drumbeat”, one of the most unknown and deadliest attacks on the U.S in history.
