                                                            "Linder".  
        Operate on the convoy immediately.  The enemy can be plotted well from the continuous contact keeper reports at hand.

    12.50   From contact keeping reports the convoy steers a general course of 210°.  I take position directly ahead and dive for submerged attack.  
    13.15   To Action Stations !  The convoy zigzags away ahead of time to 130°.  
    15.00   Secure from Action Stations.  
    15.20   Surfaced.  Hold contact on the starboard side of the convoy, distance 18-20 nm so as not to be detected.  Bearings are taken now and again on quite weak clouds of smoke.  
    16.00 BD 9859    
      Rain squalls, Vis. 16-20 nm    
    18.10   U-boat in sight.  It is "Forster".  I point out the clouds of smoke to him.  Like me he maneuvers further ahead at increased speed.  For 50 minutes a flying boat is over the convoy, must have seen us, however, does not approach us.

    continued      
    19.07.41      
    00.14   Crash dive for 4-engined land-based aircraft.  This was probably equipped with radar, since it approaches all boats positioned at convoy in turn, however, seems to have no bombs because the range [to land] is too great.  
    00.30   Surfaced.  I am positioned ahead of the enemy, at target angle 0°, I turn off a little to port, stopping, the convoy is bow right having target angle of about 5° and take the forward starboard escort ahead, turn away hard, putting him exactly astern and stop.  Turning slowly until the tightly grouped starboard column of the convoy is in a favorable overlaping shooting position.  Targets are three freighters of about 5000 GRT and a passenger freighter of about 8000 GRT with two smokestacks and high superstructure, the 2nd smokestack may be a dummy to give the impression of a more powerful auxiliary cruiser.  
    02.30   1-4 shot ! at target angle 50° and 1000 meters range.  
        All torpedoes run.  I turn away hard to port, just after I have increased speed to get in position to shoot tube 5 there are two tongues of flame and high dark explosive clouds. Thereupon a third deafening bang, an enormous tongue of flame, a whole steamer flies into the air.   It is the one with two smokestacks, he was loaded with ammunition.  A moment later a fourth tongue of flame and explosive clouds, hit amidships on the fourth steamer.  Wreckage flies into the water around us.  I order the bridge crew to leave the bridge to bring themdown to safety before the falling wreckage.  This is misunderstood as the word "Alarm" causing an unintentional diving maneuver.  Went to depth A +10 meters. Two onrushing corvettes cover us with 6 depth charges which however, lie apparently in the Bold ejected from us shortly after diving.  
    03.00   Surfaced so as not to lose contact.  However, am located immediately by the corvettes which lie astern at 800-1200 meters to starboard and port and fire with starshells and high explosive shells.  First ones very well placed.  Due to our higher speed we can slowly break away from our pursuers and now stand between them and the convoy.

    19.07.42      
    xx.x0   Fire in the diesel engine room.  Starboard diesel is out of service, port must also be stopped.  Corvettes again come on.  I decide to dive in spite of the not yet extinguished fire, because the corvettes have closed to 800 meters.  Went to depth A +70 meters.  Four depth charges, no failures Bold ejected.  Another 6 depth charges apparently lying in the Bolde.  At last the fire on board is extinguished, at depth A +40 meters with water from outside, after there was no success in suffocating this with the existing CO2 fire extinguishers.  
    04.00 CE 3381 Only one corvette is still heard in the GHG, "Asdic" not heard.   It may be that these were swallowed up by the Bolde.  
    xx.45   Surfaced.  Contact lost.  Pursued on convoy course 180°, because this was the last observed course of the convoy and the corvettes ran off in this direction.

[extra words from copy of message in radio log extract]

Experience in this Sea Area.
 
      Hardly any independents, convoys leave the main harbour at Trinidad in the morning hours in direction of the Caribbean on a northwest course and 7-9 knots, positioning of the boats is most appropriate where the convoy will be at dusk.  Boats must remain submerged by day to remain unseen.  They must strive to reach attack position during the 1st night as often as possible, because holding contact during the day is hardly possible because of strong air, working together with small coastal patrol boats.  The danger of getting bombed by very fast land-based aircraft is very great here.  If are several boats at the convoy which can not themselves shoot during the 1st night, another boat must be ordered to move off 3 hours before dawn at highest speed ahead on the convoy's main course, then this boat continues submerged at 3-4 knots in the direction of the convoy's main course, in most cases it will still have the convoy's position 3-4 hours before dusk.  The crew could rest during the other hours of the day, so that easier contact keeping is possible during the last 3-4 hours of the day especially as experience has shown that the attention of the enemy decreases during these hours of the day.  
      This contact keeping procedure can apply only to appropriate sea areas and could be applied successfully with a convoy running out from the Gibraltar Strait.  Of course the boat must then renounce an attack.  
     
Experience at the Convoy.
 
      The convoy was screened mainly by aircraft.  Sea escort was comparatively weak.  On sighting the convoy we steamed alongside at the extreme limit of the range of visibility for 30 minutes to match the speed of the convoy.  These 30 minutes have always paid for themselves with me a hundred times over.  Over the convoy sweeping aircraft have set lights and with their circles as a matter of course now and then overfly the boat's course, because of the difference between their night vision range and ours, they always keep enough distance.  Then maneuver ahead until the convoy has target angle 0° at the limit of the range of vision. With target angle set to "constant" continue the attack from ahead.  Now the aircraft gets closer, in the process the boat must make only the lowest speed and be stopped until the aircraft flies off.  The aircraft will always throw only a flare, because before he never knows whether the white foam seen by him is from his own escort vessel.  Then when the ships overlap as much as possible, shoot, turn away and run off.  Save the closest ship for the stern tube.  After the second shot [illegibel word] if at all possible carry out a
