        Attack on the surface is possible, because I am coming out of the smokescreen.  On closing the name is found to be:  "ARTHUR F. CORWIN", London, 10516 GRT.  
        On the 600-meter wavelength at 17.12 hours received:  "ARTHUR F. CORWIN" 60° 20' N, 17° 11' W torpedoed 14.39 hours.  
        I accept that U-103 is nearby and has torpedoed the tanker, therefore from 19.15 - 19.40 hours repeatedly gave Underwater Telephone Recognition Signals, no answer.  
        Initiated attack.

        Shooting data:  Target angle bow left 80°, speed 6 knots, lead angle 12°, range = 500 meters, running time 44 seconds = 660 meters.  
        At the detonation strong co-detonation of the fuel, heavy smoke and coil of fire.  Oil running out continues to burn on the water.  Fire spreads out.  Creates a hazy smoke cloud and strong fiery glow in the sky.  
        Steamer settles deeper, however continues to run.  Crew is still partly on board and is located astern.  3 cannons on the superstructure cannot be manned due to the heavy smoke.  No lifeboats are seen.  Initiated a new surface attack, because

        Bow left target angle 90°, enemy speed 4 knots, lead angle 8, range = 400 meters, running time 24 seconds = 360 meters.  The fire on the water spreads rapidly.  Must back away energetically.  
        20.22 and 20.25 hours detonations on board, apparently tanks going high order, gasoline or ammunition.  Tanker now lies burning.  Torpedoes seem sufficient for sinking.

    21.17   Crash dive.  Silent running at depth = 70 meters.  Continued to move off, sounds become distant.  
    22.26   Surfaced.  Intent to lie in wait to see if the tanker sinks.  Reloaded torpedoes, charged the battery.  Destroyer is still at times in the vicinity of the wreck, seen bearing 300°T, 6 nm against the fiery glow.

    01.47   Steamer sighted bearing 260°T.  Zigzag course around 120°. The red glow from the smokestack was seen far away.  Maneuvered ahead to determine shooting data.  Initiated attack.  Steamer zigzagged towards, as a result shooting range was very short.  Shot because I believed range was greater than 200 meters.  
    02.27   Shot one G 7a..  No effect observed.  Shot hit without detonation, probably below the safety range, the steamer stopped.  
        Shooting data:  
        Target angle bow right 80°, enemy speed 8 knots, lead angle 11°, estimated range = 300 meters.  
    02.28   Dived, to not be seen.  Initially still propeller sounds, shifted ahead.  
    02.35   Surfaced to maneuver ahead again.  Steamer is very close.  Sharp or very broad target angle.  Assumed ramming position.  
    02.38   Crash dive.  Moved off submerged.  No propeller sounds heard.  
    03.08   Surfaced.  Steamer lies abeam to port, stopped, athwart the sea.  Am now certain that the shot hit but did not detonate.  
        Maneuvered with E-motors to attack.  
    03.25   Shot 1 G 7e.  Hit between bridge and smokestack.  In the listening gear three sympathetic detonations heard, probably boiler explosions.  Steamer was down by the bow, hurriedly set out boats and sank at 03.37 hours after 12 minutes over the fore stem.  
        Shooting data:  
        Target angle bow right 70°, speed 0, lead angle 0°, estimated range = 700 meters, running time 53 seconds = 795 meters.  
        At 03.27 hours the steamer transmitted on the 600-meter wavelength:  sss, 61°14'N, 18°10' W BLACK OSPREY torpedoed.

Mast in sight bearing 340°T.  Made out as a tanker lying on an easterly course.  Maneuvered ahead to attack.  Got ahead quickly.  Tanker lies stopped.  It turns out that the tanker is damaged.  Position differs from that reported by 30 nm.

        Initiated a new attack on the same steamer.  In so doing the 3rd column made a zigzag to port.  As a result I am in the middle of the convoy.  A large steamer with a passenger superstructure astern to starboard has target angle bow right 5°.  Immediately shot at this.  As the target angle increased recognized as an auxiliary cruiser, gaff ensign, camouflaged, cannons, partly with shields.  2 masts, many stub masts.  
    23.27   Shot a double shot G 7e.  Both hit between the bridge and the after mast, close after one another, With the 2nd hit heavy sympathetic detonation, powder stench, strong pressure wave perceived in the boat.  Auxiliary cruiser breaks in two and sinks after 9 minutes in square AL 2441.  
        Shooting data:  
        Target angle bow right 90°, speed 8 knots, lead angle 16°, range 500 meters, running time 30 seconds = 450 meters.  
        Convoy goes in every directions.  Steamers zigzag constantly.  Hung on to two medium steamers.  Turned off to the NE and closed up a bit.  Other groups proceed in a similar fashion.

                On 20 February a Radio Message concerning the bearing direction of the aircraft could have clarified the situation.  For the future this will be a basic procedure.
