    20.00 AN 2336    
    22.14 N 3, Sea 2, nearly overcast, bright north horizon, Vis. good Incoming Radio Message 2013/16/061 Kr Kr:  Boat sinking slowly.  Square AF 8787.  
                                                                  U-998  
        I am located 11 nm southeast of U-998.  2-1/2 hours have passed since the detonations.  
      I believe that in the mean time U-998 has sunk.  My intention is to immediately surface and assist U-998.  While submerged, I announce what is at stake to the crew and that aircraft attack can be expected.  
    22.30   Surfaced to search for U-998 (Fiedler).   
    22.45   Recognition Signal exchanged with a German sea emergency aircraft (Do 24).  I follow the aircraft, because obviously the position of Fiedler or the sinking location is known.  In so doing . . .  
    22.59   "Aircraft" alarm - a twin-engine land-based aircraft.  Range 7000-8000 meters.  Flies past then immediately turns towards.  Recognition Signal requested at about range = 5000 meters,  No immediate answer.  Gave permission to fire for the 3.7 cm cannon.  After 3 shots stoppage due to loading mechanism failure.  The aircraft immediately fires the correct German Recognition Signal, turns away briefly and then flies exactly from astern with a dive angle of about 25°.  Permission to fire for all weapons at range 2500-3000 meters.  The 3.7 cm cannon gets off only one shot.  The twins work well.  The aircraft shoots with on board weapons however at the same time received hits from the 2 cm twins, draws close over the conning tower.  Initially pulls up smoking and then goes lower in a left turn, then pulls up again and disappears in the dark southern horizon.

    continued      
    16.06.43 West coast of Norway During the overflights no bombs were thrown.  A new attack by the aircraft, which in the meantime was identified as a "Mosquito" did not follow.  On the conning tower I have 3 severely and 5 lightly wounded.  Severely wounded are:  
                Obstrm. Berhardt (Gunnery Officer)  
                Mtr.Gfr. Machler (Gunner, port twin)  
                Masch.Gfr. Adolf (Loader on the starboard twin)  
        Lightly wounded are:  
        Mtr.Gfr. Schmidt, Gunner on the starboard twin  
        Masch.Gfr. Nork, Loader on the port twin  
        Masch.Mt. Zscharnak, Ammunition Man  
        Masch.Mt. Vollheide, Ammunition Man  
        Oblnt.z.See. d.R. Meyer, Kommandant  
    23.04   Outgoing Radio Message:  Was attacked by aircraft, square AN 2333.    U-804.  
    23.24   Outgoing Radio Message 2310/16/067:  Aircraft attack fended off.  Several wounded.  Position square AN 2333.  
                                                                  Meyer.  
    23.32   Dived to put together a new anti-aircraft watch.  
        On the aircraft attack:  Own speed before and during the attack AK.  No marine phosphorescence.  One approach exactly from astern at low altitude.  Machine gun fire, no bombs, no detection.  Fliege, Mücke, Wanze were manned.  Gear was operable.  According to statements by U-Müller, which recovered the crew of the Mosquito, they testified that they flew visually by day and that also in this case  the boat was sighted and not located [by radar], further that 4 German Recognition Signals at hand were shot, and that bomb throwing did not take place because of hits to the engines.  
        Range when the aircraft came in sight was 7000-8000 meters.  Target angle about bow left 70°, altitude 800-1000 meters, no battery charging.  Communications gear was manned.   
      There is no great desire to surface below deck. I'm not quite sure whether in the immediate vicinity of own coast (30 nm) full commitment of a U-boat to rescue comrades is justified.  I must assume that other aircraft were summoned.  
        Therefore surfacing was delayed and steered in the direction of the suspected sinking location of U-Fiedler submerged.

He sees in the failure of the coup confirmation of the order of Providence to pursue his life's goal.  The criminals had nothing in common with the Wehrmacht, whose Glory is untouched.

    15.00   Dived with crash dive, afterwards went to Action Stations and periscope depth.  
      I believe that the destroyers have sighted us too.  
        2 destroyers come closer without zigzags and speed changes, the 3rd I cannot see in the attack periscope.  My course is 270°.  Both destroyers come out [above the horizon] astern, in perfect position.  
    15.31   Reversal shot from tube 5 on the starboard aft destroyer:  bow left target angle 45°, target speed 10 knots, range 2500 meters, depth 4 meters, W S  [far shot setting]  
    15.33   Reversal shot from tube 2 on the destroyer positioned to port:  bow right target angle 80°, target speed 10 knots, range 2500 meters, depth 4 meters, W S.  
        When getting back to the destroyer shot first I see that his course has changed and he is heading exactly for the periscope at target angle 0° and higher speed.  It is already quite close.   
    15.36   Reversal shot from tube 6:  target angle 0°, target speed 16 knots, range 1500 meters, depth 4 meters, W S.  The range at the shot was no more than 1000-1200 meters.  
        Afterwards went to depth A +70 meters.  
      In order to not have a large bow down angle when being overrun, went deep with a slight down angle.  
        At depth 40 meters was over run by a destroyer.  Shortly before the shot at 15.36 hours there was a detonation fainter than the following depth charges and accompanied by strong rushing sounds.  The Soldiers with several patrols took this to be a torpedo hit.  I myself have still not heard a torpedo detonation however noted that the first detonation was different than the depth charges.  It must have been from the torpedo from tube 2, which was shot at 15.33 hours, at the time of this detonation I saw a water column at the destroyer running astern to starboard however I had the impression that had thrown depth charges.  
    15.36   2 detonations (close) depth charges.  
    15.40   2       "     "     further away than the one that was spoken of as a torpedo detonation.

        The boat is shaken by these depth charges, water entry followed at depth 2 A meters through the "Drain air exhaust head valve".  Water intake in the diesel room.  It was later determined that the exhaust duct above the head valve was torn in several places near weld joints and along a total length of about 1.25 meters. Bad welds were recognized as the cause.  The exhaust duct had a diameter of about 300 mm and is made of of 5 mm thick steel sheets welded together.  As can be seen at the fracture site, the abutting edges showed a bond thickness of a only about 1 mm.  In several places the weld seem was heavily contaminated by slag.

        Occasionally went to high speed.  Despite the significant racket in the Control room nothing came from above.  
      I can only make sense of this if something happened above.  It seemed that the boat's position was exactly known by the approaching destroyers. Exact observations could not be made because the G.H.G. was out of service (since 6 July 1944).

      When deep it became clear that taking the all around sweep and the detonation must have been a coincidence.

    02.30 BD 4939 A large shadow bearing 110°T, sharp or broad target angle [it was unclear to the Kmdt.], range 1500-2000 meters, recognized as an aircraft carrier.  Because there is no indication of target angle and speed, also my tubes must be shifted from circle setting to long loops, turned away hard to port.  The carrier was soon indistinct and passed out of sight briefly.  Turned towards again and put [the carrier] ahead to starboard.  Course of the carrier is approximately NE, therefore had a broad target angle.  While maneuvering ahead there was another larger shadow ahead to port with a destroyer on the right.  Initially put astern with hard starboard and ahead AK, then to starboard astern and came to the course of the carrier.  The destroyer passed out of sight, then came in sight abeam to starboard with target angle bow right.  Initially it seemed that he had not noticed us, then he turned into our wake to bow right target angle 10-15°, quickly grew larger at high speed.  At range 700-1000 meters red light emission (2 searchlights in the fighting top), at the same time artillery fire.  
      SW 4, Sea 3, heavily misty, Vis. about 2000 meters, drizzle, light marine phosphorescence  
      I have the impression that the forecastle gun could not bear on us due to the low range and enemy [vessels] in the field of fire.   
    02.53   After "Fire" was ordered for 2 circling [torpedoes] from tubes 5 and 6, dived with "Crash dive".  
        Set values:  Circle shot, depth 4 meters, initial run 500 meters, ancillary enemy speed 10 knots, bow right 90°.  When submerged I determined that the torpedoes in tubes 5 and 6 did not fire.  "Ready" did not get through to the stern room, the tubes were still safe.  
     

Even though the circle fan from tube 5 and 6 had little prospect of hitting, not firing remains a failure of the Kommandant and the First Watch Officer who had to ensure the fan was fired despite the short time available.  The Order Failure can not be criticized because the time from "Ready" to "Fire" was too brief from the beginning of the shot. On the other hand, staying on the surface longer was no longer possible. The reason for the fan not firing was switching too late from the 4 fan (for the attack on the carrier), to the 2-circle.

 
    02.54 to 02.55   About 10 artillery and depth charge detonations, close.

      1st patrol with a new boat, new crew and first war patrol of the Kommandanten.  
      The attack of the "Mosquito" on the Norwegian coast brought the boat and crew valuable experience.  It was recognized that operation against aircraft requires extreme caution.  The encounters with the destroyer group and the escorts of the aircraft carrier put the boat in a tight spot, which was overcome with good fortune.  
      No significant observations were made concerning surfaced and submerged detections.  Bolde and Aphrodite were not used.  
      The morale and health of the crew during the patrol was good.

Comments of the Befehlshabers der Unterseeboote
 
 

on the K.T.B. of "U 804" (Meyer) from 12.6. - 12.10.1944.

 
     
 

        1st patrol with a new boat.  The aircraft attack on 16 June gave the young crew the opportunity to prove themselves and get to know the most dangerous side of the U-boat war.  The shoot down of the aircraft was a good start.  Attack on destroyer group on 2 August was handled well and calmly.  Unfortunately the boat was not allowed the satisfaction of a sinking.  Hits on 2 units possible.  The rare encounter with an aircraft carrier was not decisively exploited due to confusion, rapidly changing situation and the understandable internal difficulties of the attack.

 
          On final remarks:  The Kommandant does not grade his own Kriegstagebuch!  
  Accredited success:  1 aircraft shot down.  
                                   2 destroyers hits possible.
