As the people of New York City went about their business, a Nazi U-boat was sneaking through its waters
Early in the evening of 12 June 1942, the German submarine U-202 sighted the American coast. For 15 days, the vessel had travelled the 3,000 miles across the Atlantic undetected, but the most perilous part of their mission lay ahead.
Captain Hans-Heinz Lindner switched from diesel to silent electric motors as the submarine edged slowly inland towards the Long Island beach. On board, the four Nazi saboteurs made their final preparations, checking the contents of their four small, wooden crates and folding their civilian clothes into the canvas sea-bag.
