Coldman, Elliot "Incident at the Wreck Buoy."

Improbable (but public morale-boosting) tale set off the coast of North Carolina. The crew of an American ship sunk by a German U-boat early during the War gain revenge when another “Heinie” sub subsequently snags itself on her wreckage. Having been declared a menace to navigation, the ship is soon thereafter blown up by a wrecking crew — and the snagged U-boat goes to the botto with her.
