        Was first perceived by the bridge watch at a range = about 500 meters.  Flew over the boat, from port astern and released a string of bombs.  
        (From the 2nd WO's statement 4-5 bombs, estimated at about 50 kilograms, one detonated beside the 3.7 cm canon in the port upper deck.  Heavy, dull detonation and smoke cloud.  
        Perception in the boat at the detonation: most believed that the aircraft bomb was further abeam in the water.   
        Failures (initially discovered!):  
        1.)  2nd WO and 1bridge visitor wounded, apparently seriously.  
        2.)  Leak in the pressure hull in the diesel room.  
        3.)  Port diesel out of service.

    15.14 EO 1252 Four stern torpedo storage canisters bent and punctured.  A tail piece from an Ato is missing.  Both exterior exhaust valves cannot be moved.  Main ballast and reserve fuel oil tank 3 port and fuel oil tank A port are leaking.  The port diesel cooling water intake is open.  Initially it is sealed from the outside with leak stuffing material.  However, it cannot be fixed from the inside and therefore, will be blind flanged from the outside shortly before dusk.  
        Initially the port diesel is completely out of service.  A large dent in the pressure hull has crushed pipes inside the pressure hull.  Starboard diesel is in service, the aftermost (inner) exhaust gas valve cannot be closed because of deformation of the E-motor bulkhead.  
        2nd WO and a bridge guest wounded by fragments and severe bruises, probably both have multiple broken ribs.  Bridge leading seaman and the other bridge guest somewhat dazed by shock effect, because both were thrown about.  
        It was determined later that the aircraft was brought down by its own bombs.  
        Evidence:  
        1.)  Explosion and, in addition, flash ahead to starboard on the water.  
        2.)  Aircraft parts in large numbers on deck, equipment pieces, glass etc.  
        3.)  1st Watch Officer and the 2nd bridge guest have similarly seen apparently bleeding people with life jackets in the water.

        3.)  . . . .  
        4.)  Naval square.  
      EE 8292 The condition of the wounded is better while proceeding on the surface.  Nevertheless, due to the condition of the boat  
      I intend to remain submerged for one more day, specifically until EE 67 having reported aircraft bombs earlier from EE 85.  Believe that a meeting with Vowe is more favorable, because supply for repair is possible at the same time.  Also, a meeting with Engelmann would force me to move from this area unnecessarily.  His appearance would also take a few days.  The first priority is to leave the air threatened area as quickly as possible.  The internal injuries of the wounded can be looked after by laymen.  
      EE 8292 Attempt to send a Radio Message on Ireland circuit:   
        Meeting Vowe in spite of delay more favorable because of the condition of the boat.  2 men with splitters in the head or back, heavy bruises, likely broken ribs.  Pulse, temperature, breathing normal.  
                                                                  Zschech  
        The boat was not heard.  
      EE 8269 Same attempted on America II Circuit.  As before the boat was unheard.  
      EE 8344 Sent the Radio Message on America II Circuit.   
        Headquarters heard (volume 2-3), then asks for some groups.  Because communication was delayed, headquarters has obviously received the first 17 groups (the Radio Message had 46 groups, the first part contained the suggestion concerning Vowe), communication is broken off by the boat because of the activity of foreign interferers and because of the length of the communication.  The radio repeater does not answer.   Because the boat must soon dive again and I suppose that the most important part of the Radio Message, namely the beginning, will be deciphered because of the difficulties with the Radio Message delivery on all circuits (Coastal Circuit could not be heard) the radio message was not sent one more time.

    23.52 EH 3749 surfaced.  Because I cannot catch up with the steamer with one diesel, pursuit not taken.  
        Steamer not reported by Radio Message, because data was too inaccurate.

    20.00 EH 3119    
    22.05 DS 9773 Shadow bearing 350°T.  
        Identified as a freighter with goal masts, 6000 GRT.  
        Maneuver ahead with one diesel again impossible.  
        Plotted data:  Base course 140°, zigzags up to 30°, 12 knots.  
        Attempt to attack before the moon completely rises, on the surface.  
    22.30 DS 9776 Two-fan on tube V and VI:  
        Eto, depth 3 meters, target angle 110°, speed 10 knots, range = 3000 meters.  
        Miss due to large range or probable failure due to bomb damage.  Now moon rises above the horizon.  Steamer is positioned in the moonlight.  As it turns out, the boat cannot get ahead because own speed is too low.  From experience, diving from high speed also bad.  That is why at all costs I try to stay on the surface as long as possible, in order to use all torpedoes because this is likely to be the last opportunity.  
    22.59 DS 9776 Two-fan from tubes I and IV:  
        Eto, depth 3 meters, target angle 120°, speed 10 knots, range = 3000 meters.  
        Miss due to large shooting range.

    23.05 DS 9776 Single shot from tube II:  
        Eto, depth 3 meters, target angle 100°, speed 6 knots, range = 3000 meters.  
        6 knots set as enemy speed, because a plotting mistake may be present, and higher driving speeds were covered by the two fan.  
        Miss as a result of too great a shooting range.  I still want to make an attempt with an Eto whose gyroscope angle had been set previously in a fixed position by an operating error.  
    23.55 DS 9779 Single shot from tube III:  
        Eto, depth 3 meters, target angle 120° degrees, speed 12 knots, range = 4000 meters.  
        Miss due to too great a shooting range.  
        I now believe further torpedoes would be wasteful.

      SW 1-2, cloudy, 1020 mb, Sea 1    
    00.14 DS 9779 While running off a sudden detonation.  Acceptance: the pistol fired at the end of the run distance at great depth.  Other additional possibility:  gyroscope failure as a result of operating error mentioned above, because detonation was estimated at 15-2000 meters abeam.  
        Am certain it was a torpedo detonation, because the typical metallic sound and afterwards the rolling bang could be heard.  
    00.45 EH 3121 Steamer out of sight,  reloaded.  
    02.05 DS 9773 A new steamer in sight bearing 45°T.  
        Because here certainly the same circumstances with the steamer are present as before (basic course and speed the same), I retreat again after a short time.  
        Because apparently by chance a cluster of traffic exists here, I report the steamer sightings by Radio Message.
