At four o'clock on the morning of June 13, 1942, four men, in the fatigue uniforms of the German Marine Infantry, were landed in a rubber boat by two German sailors on the beach at Amagansett near the tip of Long Island, 125 miles east of New York City. They changed to civilian dress and then buried in the sand their uniforms and a supply of explosives, incendiaries, fuses, detonators, timing devices, and acids. They carried with them some $90,000 in American currency and had an elaborate list of American factories, railroad centers, bridges, power plants, water supply systems, and the like. They were accosted by an unarmed Coast Guard patrol. Alleging that they were fishermen, the four men sought the silence of the patrol first by threats to kill him and then by a bribe. He accepted $260, promptly reported the incident, and a squad of Coast Guardsmen shortly discovered the buried articles. A submarine was seen and heard off shore. The four men went to New York City.
