U-Boat and Submarine Factoids

Did You Know?

by Oblt. Ernst Schmidt (10-1983)


  • Potash cartridges were used by the crew by mouth to remove the carbon dioxide from the air when submerged for a longer time? The filtering or the chemical air purifiers were not sufficient, they were noisy and used the much needed battery power while under depth charge attack.

  • the radar screen on an aircraft flying at 9,750 feet would reveal surfaced U-Boats up to a distance of 80 miles?

  • there were more than 300 destroyers protecting the convoy system and over 700 escort vessels of other types employed on the high seas alone?

  • engaged in inshore convoy protection and general ASW duties were another 2,000 ships and boats?

    Gerhard Nolde

    Where is U-Boat Skipper Gerhard Nolde? He was last seen on 20 April, 1945 at Hitler's Birthday Party. Let us know - it is most important for research in progress for our INTELLIGENCE PAGE by CORDEZ.

    RITTERKREUZ mit EICHENLAUB

    The 18th winner of the OAK LEAF CLUSTER to the KNIGHTS CROSS was KPLT FRIEDRICH GUGGENBERGER (269-+-1987), Skipper of U-81. The award was made 8 January, 1943. It was U-81 under GUGGENBERGER that sank HMS ARK ROYAL.

    He was born on 6 March in 1915 in München (Munich); was in Crew (Class of) 34; his highest rank was Kapitänleutnant; he was Skipper of U-81 and then U-513; he was one of the U-Bootfahrer who tunneled out of the POW camp at Papago Park, Arizona; he ended his days in May of 1988 in Garmisch.

    Far-East Boats

    From the information sent from WERNER K. HOFFMANN (327-LIFE-1987) we learn that U-1062 carried a load of torpedoes to the Far East. This was the first mission of this rare TYPE VII-F boat & she was sunk with all hands on her return voyage SW of the Cape Verde Islands by the destroyer escort USS FESSENDEN.

    5th LARGEST

    From data sent by CAPTAIN ROBERT THEW (333-+-1987) we learn that the 5th largest ship ever sunk by submarine was the 29,150 ton Royal Navy battleship HMS ROYAL OAK. Who doesn't know that U-47 under Günther Prien (pictured here) slipped into the Fleet Anchorage at Scapa Flow on the night of 14 October, 1939? In an issue of LIFE Magazine the following week, there is a photo of Prien sitting in a chair with his wife standing over his shoulder. Prien is speaking into a telephone and the caption reads:

      "Hello Mother; I just sunk a battleship."

    Günther Prien had only seventeen more months to live.....

    For KTB #113 next month, what was the 4th largest ship ever sunk by submarine?

    46 Italy had signed the armistice with the Allies on 8 September, 1943 and the battleship ROMA was sunk on 9 September by German aircraft so she could not be used against the Kriegsmarine or the remaining German merchant fleet.
