One of the most spectacular, albeit minor, Allied victories of World War II had absolutely no Allied involvement whatsoever.
It came in the form of the Nazi submarine U-1206. The Type VIIC boat was a technological marvel armed with two anti-aircraft guns, five torpedo tubes, and most impressively, a complex toilet that could flush waste into the ocean from deep below the surface.
So complex was the subs plumbing apparatus that each crewman of the U-1206 needed to be specially potty trained on its operational capabilities prior to its April 1945 launch from Kristiansand, Norway a matter of weeks before the war in Europe ended.
The boat was just eight days into its maiden patrol when its captain, 27-year-old Karl-Adolf Schlitt, heard natures call to expel the sort of bodily ordnance that rhymed with his name.
