Operation Drumbeat: The Secret U-Boat War on America’s Doorstep!

Operation Drumbeat (Unternehmen Paukenschlag) was one of the most devastating U-Boat offensives against the United States during World War II. In early 1942, German submarines struck almost unopposed along the American East Coast, sinking merchant ships within sight of city lights. This video reveals how the attack unfolded, why the U.S. was unprepared, and how Germany briefly dominated the Atlantic right off America’s shores.
