        Wagtail experience from Gysae.  
        1.  Have constantly flown since the latitude of Madeira.  In transit two short flights daily are convenient.  Wagtail used successfully to sea state 4, medium high Swell, where a float plane would not be possible.  
        2.  Landing is the critical point.  Pitching is not an impediment, because the landing platform is in the center of the boat and is steady.  It is expedient to wind in the last meter of cable with the hand crank.  
        3.  Tubes flooded by leaking drains.  As a result both set of blades soaked and temporarily not ready for flight.  Also the hoist.  Here lubrication points for brake cams are necessary, also access for the brake shaft.  
        4.  Stricter selection of personnel is necessary.  Of those ordered on board only one is fully operational.  More value should be placed on training in aircraft maintenance.  
        5.  Other items follow.  14 E-torpedoes, 12 A-torpedoes, 403 cbm.  Naval square EJ 8436.

    19.25 GR 6719 Intermittently flashing light sighted bearing 40°T.  
           
    19.44 GR 6719 Smoke cloud in sight bearing 20°T, held on to it at highest speed.  Further clouds of smoke come into sight to the right and left of it.  
        It is a convoy, about 9 ships, moving in two groups, course about 125°.  Protection consists of several, small shadows set out to seaward, likely escorts.  Over the convoy lighted aircraft move back and forth.  
20.00 GR 6719
  SSW 2, Sea 1-2, 9/10, Vis. 5 nm
        The following location was observed operating:  
        1)  Horizontally polarized 141 cm, search detection during the entire evening.  
        2)  Horizontally polarized 170 cm from aircraft.  
           
    20.18 GR 6727 From port abeam beam a lighted aircraft flies from the boat.  Low altitude.  Engine sounds are heard clearly on the bridge and in the conning tower.  Simultaneously a report of a roaring aircraft detection from the Fu.M.B.  A machine gun is immediately manned by the watch, both others immediately thereafter.  
        Emergency radio message detected.  
        Aircraft flies behind the stern and continues out to sea.  At the same moment sudden cessation of the detection.  No permission to fire so as to remain unnoticed.  
        Afterwards got ahead in shooting position on the third steamer group.  Steaming at 8 knots.  While getting ahead surface ship detection is continually very loud.  Therefore, believe detection is forward looking.  
           
    21.25 GR 6752 Two fan from tubes I and III, depth 4 meters on a large steamer, which drives with smaller ones overlapping.  Bow right, target angle 100°, enemy speed 8 knots, set range 1500 meters.  
           
    21.27 GR 6752 Two fan from tubes II and IV, depth 4 meters on a large tanker.  Enemy speed 8 knots, bow right, target angle 70°, set range 3000 meters.  
        Both fans were fired at long range (2500 meters) because of the laterally offset escorts and detection growing louder.  After 7 to 8 minutes two detonations heard.  But no success observed.  Anyhow, the ships fired at are not hit.  Assumption: end of run detonation in the shallow water.  In the first fan one torpedo is a surface runner.

        Again got ahead, at the same time loaded 2 torpedoes.  Drove at the same speed [as the ships] steamed.  Results this time 9.5 knots.  The first steaming was neglected due to bad visibility.  This plus the surface runner explain the misses.  
           
    22.10 GR 6764 Hospital ship on opposite course insight on the far side of the convoy.  Occasionally the coast can be recognized.  
           
    23.53 GR 6769 Two fan from tube II and IV, depth 3 meters on large freighter.  Enemy speed 9.5 knots, bow right, target angle 90°, set range 1000 meters.  Afterwards turned to starboard for a stern fan on a tanker.  At the same time the escort proceeding at 40° echelon (distance 1500 meters) to the tanker passes at short range, however, does not sight us.  
           
    23.55 GR 6769 Two fan from tube V and VI, depth 3 meters on tanker.  Enemy speed 9.5 knots, bow right, target angle 80°, set range 1000 meters.  
        After a running time of 2 min 12 seconds (1980 meters) two detonations on medium sized freighter.  Minimum estimate 6000 GRT.  Sheared off to port, stops takes a heavy list to starboard.  Emergency lights set.  Crew takes to the boats. After 2 min 20 sec. (2100 meters) engine hit on tanker.  Remains lying stopped, settles deeper astern but does not sink.  Convoy continues its journey.  An escort and a large blue-funneled freighter shear off to take aboard the lifeboats of the freighter which has sunk over the bow in the meantime.

        Because no defense or pursuit is noted, I suppose that the enemy figured on mine hits.  
                                 Intention: Restart for a coup de grâce on the tanker.  
           
    00.40   Tube IV is reloaded.  We are approaching approximately 2000 meters. The large freighter stays near the tanker at low speed.  Both escorts circle.  Therefore, delayed finishing shot.  
           
    00.46 GR 6769 Shot from tube IV, depth 5 meters, on freighter.  Enemy speed 0.  After 2 minutes 20 seconds (2100 meters) hit in engine.  
        Freighter similar to type "PERSENS" or "ACHILLES" minimum estimate 8000 GRT.  Escort did not react.  Therefore tube VI reloaded and restarted again.  
           
    01.10 GR 6766 Coup de grâce from tube VI, depth 5 meters on tanker.  Enemy speed 0, this is empty type similar to "W.B. WALKER".  After 2 minutes 35 seconds (2325 meters) hit in stern, ship breaks at the stern third and settles substantially deeper.

        Because there is still no defense, tube III reloaded, in order to sink the [illegible word] tanker.  
           
    01.53 GR 6766 Shot from tube III, depth 6 meters, enemy speed 0, after 2 minutes 14 seconds (2010 meters) hit amidships.  Tanker burns and sinks over the stern.  On running off a part of the fore ship still floats on an air bubble.  
                                 Intention: Use the short time before twilight to run to deep water. Because the incidents could be seen well from land, I expect a quick response.

        Maneuvered ahead at highest speed before dawn to be in attack position if the fog rises.  
           
    07.49   Dived in changing visibility between 600 and 1000 meters, because by plotting we must be ahead of the enemy.   However, the maximum for the enemy bears [illegible two words] 94°T, strength 4/5 decreasing.  Nothing is seen in the periscope.

  NE 0-1, Sea 0, fog
           
    08.19   Surfaced, as there is no opportunity to attack.  
        As a last resort I intend a surprise attack on the surface out of the fog.  
        To this end, will maneuver ahead at high speed, at the same time approaching the convoy to the limit of visibility, then open outer doors and attack.  
        We must hurry, because fog appears to be breaking up and the boat may be detected by day air immediately.  Later submerged attack with Atos in the mirror smooth sea in flat water appears inappropriate.  
           
    08.44 GR 2536 While angling in at high speed towards the last held convoy position the U-boat suddenly encounters patches where the fog has broken up at the convoy.  By chance it had stopped before for about 5 minutes and then turned to a westerly course to assemble.  
        A modern destroyer is positioned at the head, then approximately 12 medium-sized steamers (including two large-sized) also 2 corvettes and a peculiar gun boat.  
        We are detected immediately and are taken under fire by all ships.  Prompt opening of the outer doors is not successful because several are stiff from warped fairings.  
        Turned away behind the numerous short impacts at highest speed and zigzag courses in the fog, 2 escort vessels take over the pursuit, also throwing depth charges.  2 steamers transmit U-boat warnings on the 600-meter wave. (Position is too southerly).

        The first torpedo left the tube, however, does not run further, but sinks instead.  Due to a failure in the electrical launch system the 2nd torpedo is launched by hand a few seconds later.  
        From approximately 1-1/2 minutes to 2 minutes the long glowing track of a torpedo is seen at the height of the forward mast, so that a hit is assumed.  However, steamer shows no effect and maintains course and speed.  
        After about 7 minutes a torpedo detonation is heard in the boat. Probably an end of run detonation.  (It was later determined that the steamer has deployed protective torpedo nets. See KTB page 93).

        Afterwards periscope was retracted because of the mirror like sea and the closeness of the steamer.  After 23 and 24 seconds 2 hits are heard.  In the extended periscope determined that steamer was hit twice in the foredeck. (Before and after the forward mast).  
        The torpedoing report of the steamer is received with the rod aerial. (Position is correct).  Steamer sinks up to the foredeck to the waterline, the cruiser stern with rudder and propeller at times out of the water.  However, the ship does not sink.

        Hence a coup de grâce from tube VI.  Depth 6 meters, range about 900 meters (missed).  Unexplained failure (possibly torpedo nets).  Determined that steamer had long torpedo nets on both sides to the stern.  In addition many spars extending from the hull.  On both sides of its gantry masts are long slender poles which are the hangers from which the nets are suspended.  (Photographs of the steamer were taken in the air search periscope.)

        It is the Canadian freighter "JASPAR PARK".  Cargo tea and tobacco from Calcutta to Durban.  Size probably similar to Liberty-ship 7000 GRT (from the statements of the crew 1000 GRT.  Believed likely cargo displacement.) Constructed in 1942.

        Presence of the torpedo defense nets are openly admitted by the survivors.  Up to now they had worked well and during the present day, unfortunately, had not been deployed.  
        (We did not expect you)  Concerning the possibility of partial torpedo defense nets during the night and at the coup de grâce no clear picture is to be agreed.  Particularly as in both boats there are mostly "deadbeats".
