On Jan. 13, 1942, German U-boat attacks officially started against merchant ships along the Eastern Seaboard of North America. From then until early August, German U-boats dominated the waters off the East Coast, sinking fuel tankers and cargo ships with impunity and often within sight of shore.
In less than seven months, U-boat attacks would destroy 22 percent of the tanker fleet and sink 233 ships in the Atlantic Ocean and the Gulf of Mexico. The U-boats killed 5,000 seamen and passengers, more than twice the number of people who perished at Pearl Harbor.

The U.S. Navy lied to the public about the terrifying U-boat attacks. The news media agreed to government censorship, which helped to hide the military’s incompetence in protecting shipping and the lives of merchant seamen.
