On November 29, 1944, two German agents landed on the shore near Hancock, Maine. They had set sail on September 22 aboard the German U-Boat 1230. The mission was to gather information about the effectiveness of German propaganda and gather intelligence on American shipyards, airplane factories and rocket-testing sites. William Colepaugh and Eric Gimpel came ashore in a rubber raft, armed with cash, guns, diamonds and other spy equipment. They made it to Boston and then New York city where Colepaugh, an American who had gone over to the German side, engaged in an extended course of nightclubbing and womanizing. Gimpel attempted to actually do some spying. Colepaugh ultimately turned himself in, admitted he was a spy and gave Gimpel up as well. They were arrested in late December. They were ultimately convicted of espionage and sent to prison. For the full details of the story see: https://en.wikipedia.org/wiki/Unternehmen_Elster.
