Citat:In "HIRSCHFELD THE STORY OF A U-BOAT NCO 1935-1945" (Pen & Sword/Cassels/USNIP), Wolfgang Hirschfeld describes how the stern of U-109 while off Greenland, on or about 20 May 1941, descended as a result of crew manometer error to a depth which he estimates at over 300 metres because the indicator was off the scale. The boat was upright in the water and the stern section abaft the last watertight door was fully flooded. When the control room petty officer juggled all compressed air aft in a last desperate attempt to save the submarine, she "soared up to the surface like a rocket".
