    20.00   Forward destroyer suddenly comes with target angle 0° by complete surprise towards our position ahead of the convoy to port.  At highest speed ran a race for 20 minutes with the destroyer.  Distance about 8000 meters.  Thereafter he has enough steam to get closer.  
    20.30   Crash dive, turned away 90°, destroyer runs at highest speed to the diving location and throws about 30 depth charges.  At the same time silent running, also the depth charge thrower.  Creeping speed.  Apparently successful.

    24.00 BC 8395 Then he suddenly runs in from low range at medium speed, exactly overruns the boat and throws well-aimed depth charges.  No locating was detected.  The tracking of the U-boat after hours of painful crawling speed is completely inexplicable.  Two exact overruns and about 20 severe depth charges.  A damned clever destroyer:  English not American.  Despite depth = A +40 meters.  All rudders several fuses failed and some valves sprung.

        Maneuvered ahead with heavy ground sea.  Tanker runs at about 14-15 knots.  At greater range behind him a smaller shadow.  Steamer of medium-size, on the same course with same speed.  It could be a small patrol vessel, however much closer.  With the seas difficult to recognize, but probably freighter farther away.

        3-fan from tubes I, II and IV:  
        Target speed = 14 knots Spread angle 10° selected, to possibly get a second hit on the tanker.  Fan shot due to high enemy speed and weather conditions.  2 torpedoes shot out with bayonet.  No hits on tanker despite exact data.   
        Target angle = 90°  
        Range = 1800 meters  
        Depth = 3 meters  
        Spread width 100 meters  
        Running time 6 minutes 32 seconds  
        Hit with enormous detonation, covered by tanker shadow, on freighter 5000 GRT.  
        New maneuver ahead, to shoot last torpedo in new attack on tanker.  It was only due to the weather situation that all 3 torpedoes missed the tanker, since the data was plotted exactly.  Freighter shadow is no longer seen, disappeared, sunk.  After torpedo detonation the tanker slows to 11 knots.  New maneuver ahead thereby facilitated.  Ground sea is always decreasing.  
    07.06 DC 1177 2nd attack on tanker.  Data plotted exactly again.  
        Target speed = 11 knots    
        Target angle = 86° Hit a bit behind the center, behind the large bridge.  Enormously strong detonation.  Tanker is half loaded in ballast.  
        Range = 800 meters  
        Depth = 3 meters  
        Running time 35 seconds (500 meters)  
        Tanker disappears temporarily behind the fire and smoke.  Afterwards lists about 40° to port, stern sinks first.  Ran off because of the shallow water and the expected patrol vessel.  All torpedoes expended except for the over deck Atos.  
        Set off to sea.  Last observation, slowly sinking of the tanker over the stern with heavy list.  Large tanker "STANCAV MELBOURNE" 10444 GRT.  After torpedoing the tanker reported the
