It may not be a date that will live in infamy, but June 13, 1942, is certainly a date of historic importance. Shortly after midnight, four trained German saboteurs landed in the fog on the beach near the Coast Guard station on Atlantic Avenue in Amagansett. They had rowed ashore in a collapsible rubber boat filled with explosives, clothing, several thousand dollars in cash, and a two-year plan to blow up aluminum and magnesium plants, canals, bridges, waterways, and locks, according to the Sea Frontier War Diary, a document held at the National Archives and Records Administration.
