The Vessel and Her Loss
Winneconne was a British-built steel steam freighter operating for American owners out of New York. On June 2, 1918, during a single-day rampage off the New Jersey and Delaware coast, the German submarine U-151 stopped and sank her along with several other American vessels. The crew was taken off safely before the ship went down, and there were no casualties. Her loss was part of a widely reported wave of U-boat attacks that briefly brought the war to the mid-Atlantic coast.
