• The U-Boat Bases in Maine

  This theory claimed that German submarines were using hidden coves, inlets, or fishing harbors along the Maine coast as clandestine refueling or supply points even before the United States entered the Second World War. In stronger versions, these sites were said to include sympathizer networks, fuel caches, signal systems, and covert landings by agents. The theory drew on the long vulnerability of the North Atlantic coast, real wartime U-boat operations off American waters, and the persistent public tendency to imagine rugged coasts as ideal places for secret bases. The specific claim that U-boats were already refueling in Maine in 1938 belongs more to rumor culture than to documented prewar operations.
