    01.40   Aircraft in sight close by, possibly a Sunderland, comes from the south, flies over forward of the bow, turns up, is then no longer seen.  Because the engine sounds remain in the vicinity and are loud,  
    01.43   dived.  
    02.19   Surfaced.  No further aircraft or sounds in the vicinity.  
    03.53 Point Tanne UA seems to have a broad oil trace.

      NE 4, Sea NE 3, 4/10, Vis. medium, +16°C 2 He 115 take over close escort.  1 Condor aircraft passed for reconnaissance sweep.  
    08.34 - 09.00   Test dive up to 09.00 hours.  
    10.00   A third He 115 appears as relief.  
    12.00 BF 8349 lower-right Day's run:  Surfaced     192.2 nm  
      EbyS 4-5, Sea E 4, 4/10, Vis. very good, +17°C                  Submerged    1.5 nm = 193.7 nm.  
    12.30   From Radio Message U-boat situation:  
        2.)  Convoy detected departing Gibraltar yesterday evening.  Operation continues.  
        As can be seen from the above, we must get well clear of the convoy.  
    16.00 BF 8248 center    
      E 5, Sea E 4, 4/10, Vis. good, +17°C    
    18.00   Clocks set back 1 hour to M.E.Z. [Mitteleuropäische Zeit = GMT +1]  
    21.00 BF 8147 upper-right Escort aircraft broke off close escort at 17.45 hours.

    01.00 BF 7349 Steered west behind "PUMA".  
      E 6, Sea E 5, 4/10, medium bright night, Vis. moderate, +15°C    
    09.00 BF 7158 Test dive until 08.32 hours.  Weather is favorable for transfer.  Seas may not increase much but because then driving at higher speed into the seas will be in question.  
      EbyS 7, Sea E 5-6, 3/10, misty, Vis. medium  
    11.50   Radio Message to UA for PUMA:  Today air reconnaissance with 4 Condors between 43°N and 47°N to 19°W 14.00 hours in the west.  Repeat tomorrow with up to 2 aircraft anticipated.        B.d.U.  
        I believe the address of this Radio Message = To PUMA - is dangerous.  According to Operations Order I re-transmitted it to PUMA.  
        The Radio Message gives, if the enemy is reading our general traffic - and I take that as likely - great insight into the type and area of operations.  
    13.00 BE 9367 Day's run:  Surfaced     288.5 nm  
      E 7, Sea E 6, 5/10, misty, Vis. medium, +14°C                  Submerged      1.8 nm = 290.3 nm.  
    17.00 BE 9347 lower-left corner The lubricating oil consumption is unusually high, especially for the port diesel.  Attempted to find the leaks and remove.  
      E 7-8, Sea E 6, 4/10, misty, Vis. medium, +14°C  
    19.00   Set clocks back 1 hour to M.G.Z.

    continued      
    24.10.41      
    19.41 BE 9259 center-left edge "PUMA" reports vessel in sight ahead.  Initially PUMA continues on old course and goes on course 300°, when by turning away UA suggests to him the possibility changing course. "PUMA" makes the basic error, with "UA" standing before him, therefore directly towards the enemy, of sending Morse with his very bright searchlight.  
      Evening twilight  
        (The signal service on PUMA is actually extremely clumsy. From the naval signal personnel there is nothing to report.   Most cases confirm that one of the ship's officers is signaling, the normal merchant ship signal procedure.  
        Each message must be given 3 to 5 times.  It takes a long time for urgent quick signaling, it is insufficient)  
        The reported vessel was not sighted by "UA". It remains questionable whether or not it is an illusion.  
    22.15   PUMA again goes to course 270°.  
    22.30   Supercharger out of service.  Bearings damaged.  Repair by onboard means is questionable. (The work order of the boat to check the supercharger during the shipyard period was dropped by the Flotilla.)  
                                                
    25.10.42      
    08.00 BE 9118 upper-right Radio Message to UA for PUMA:   
      E 5-6, Sea E 4, 9/10, bright night, Vis. medium Today's remote reconnaissance without sighting the enemy.  25 October reconnaissance between 43°30'N and 47°30'N up to 22°W with 3 Condors at 14.00 hours to the west.  
    10.00 BE 8237 upper-right    
      EbyS 6, Sea E 5, 10/10, Vis. medium, +15°C    
    11.13   Test dive and servicing of the torpedoes until 11.42 hours.  
        Up to this morning 30 cbm of fuel oil have been consumed.  Because "PUMA" has only 35 cbm for us on board, meaning this supply cannot extend operational range.  
        Because "PUMA" does not run at 12 knots but between 13 and 14 knots, UA can just keep up at GF = 15 knots at 13.1 cbm of fuel per day.  
        The equipping of PUMA with fuel for us proves to be too low by half.  
    14.00 BE 8217 upper-right Day's run:  Surfaced     299.7 nm  
      E 5-6, Sea E 4-5, 10/10, cloudy, Vis. medium, +16°C                  Submerged      2.3 nm = 302.0 nm.

    12.45 CD 3673 Began fuel transfer from "PUMA".  
        The taking over of the gear is very difficult in the considerable swell; PUMA also has difficulty. The people on deck are up the neck in the water many times. Naturally a midshipman falls overboard, but is quickly fished out again.

        Taken over:  35 cbm.  
        Consumption to now:  70 cbm, therefore exactly double.  
        PUMA gives an inventory, with the result that 46 cbm were taken over.

    15.00 CD 6739 Released by "PUMA".  Great farewell.  Initially continued on PUMA course diesel-electric.  PUMA drew ahead only gradually.  
    17.00   Officer-Only Radio Message to UA:  
        1.)  For U-boat attack the currently released area includes the following areas.  
                1.)  Between the latitudes from square CF 2522 and square ES 4888 the area east of the longitude of square Dora Gustav 2455.  
                2.)  South there from up to the latitude of square 2757 of the large square that lies south of square ES, the area east of the longitude of square ES 8721.  
        2.)  Outside these area must expect several own ships, therefore released case by case depending on the situation.

        Continued to run on the same course until the beginning of twilight.  
    22.00 CD 9153 Came to course 140°.  This is not the shortest course to the attack free area, this would mean too great a detour on the way to the designated operations area.  Therefore I decide to steer the more southern, somewhat longer, course of 140°.

                                              Situation Considerations.  
      After passing the Cape Verdes the boat entered the actual operations area of the Southern Boats.  Further instructions for UA were not yet available at the time. The area off Freetown is still appears sparsely traveled. U-107, U-125 and U-103 also apparently remain here without success.  U-126 has, as far as is known, reported traffic, however neutral.  
      In the South Atlantic at the latitude off German Southwest Africa U-68 had few but beautiful successes, off Walvis Bay however no traffic met.  
      Due to the high fuel consumption for the PUMA escort task, only half of which was supplied, the action radius of UA extends to Walvis Bay.  There is no attack reserve. So going there would only be worthwhile if heavy traffic was expected, or if prior supply was possible.  
      Unfortunately other areas appearing worthwhile are not currently released. The delimitations of attack areas here in the south, which directs the U-boats in poor ship traveled areas in order to keep the rest of the Ocean

        for sporadic own independents turns out to be a great hindrance for the U-boats, even the western boundary at 30°W is annoying. (See the large steamer on 31°W on 1 November.)  
        I intend to proceed further in the general direction of Ascension and Walvis Bay.  I expect to get further orders now and retain most of my fuel for long range operations.  
    11.30   Radio Message:  Eckermann is reminded of report concerning special task.  
      It was arranged that:    
      a)  A Short Signal in B.d.U. Orders.  This was sent on 2 November and again on 3 November.  
      b)  In the Group West Orders: a report concerning  
              1.)  Further intentions of the Kapitän if deviating from previous orders (with supplement if necessary)  
              2.)  Sighting of the enemy.  
              3.)  Special events, combat operations.  
           
      To all points there was nothing to report.  Therefore only a Short Signal was sent.  A message beyond the Short Signal, if nothing special was to be reported was not ordered from the wording of the order, however, apparently was intended.  
      Therefore Radio Message:  task completed 29 October square CD 91 without special occurrences.  ES 34, 185 cbm.        UA.  
      The delivery of this Radio Message is very awkward, since the boat is about 500 nm from Freetown, also possibly in the U-126 operations area.  Furthermore, by using Bathurst there are good bearing possibilities and angles.  The radio message is superfluous, but unfortunately now regarded as ordered.  It is also not advisable to delay delivery, because I think it is better to transmit north of Freetown, not south closer to the subsequent operations area. One advantage lies in the fact that the B.d.U. is made aware of the unfavorable evolution of the fuel situation.

      Situation:  
      "UA" is positioned in square FE 83 to look south of the Equator.  The fuel supply is still sufficient for 7700 nm.  The route "via Liberia coast - supply place - homeland is 8000 nm.  So due to fuel it is no longer possible, as recommended by the B.d.U., to search in Freetown and the coast to the east, time would be available for 3 days.  
      I intend therefore to go to the area freed by U-68 to operate there and then to be at the supply place at the beginning of December, the boat has just enough fuel for the return transit.

        Out of caution communications with PYTHON were however extremely restricted.  
      [V-boat = Verkehrsboot - a picket boat, ship's boat] The V-boats from PYTHON had in the mean time gathered the people from the hose and transport boats and come alongside.  27 men were taken over.

Enemy turns off until it is almost transverse and visibly reduces speed.  Additionally I think I see a signal.  Range about 3000 meters.  I suppose that he has seen the boats, observed the situation and must make a great circle around the dive location and shoot at PYTHON from

        Apparently the enemy increased speed again.  (Later comparison with the sketch of PYTHON, showed that the occasionally slow speed of the enemy had also been observed from there.) Moreover about 1 minute after the shot the enemy turns to target angle 45°.  
    18.19   Quickly comes closer such that I decide on a stern-fan.  Speed was initially set at 20 knots.  Despite the ongoing combat the shift takes place so slowly that I again reduce the enemy speed setting to 12 knots.

At 18.35 hours "PYTHON" received a stopping volley from long range, about 18000 meters.  He then turned to starboard, stopped, and at 18.45 hours put out his boats.  At the same time he was blown up and set on fire, and sank at 19.32 hours.

        Began taking over the crews.  In the mean time U-68, which had previously dived before the aircraft, approached.  
    20.50   Among the first taken over, was the previously wounded Kaptlt. Kühn (First Officer Ship 16).  He hangs in his transport hammock just in the conning tower hatch when an aircraft flies from the south.  At the same moment, the "DORSETSHIRE" comes in sight again with its cloud of smoke bearing 220°T.  
        Apparently he has not noticed the presence of the U-boats and wants to take over the crew of the PYTHON.  
    20.52   "U-68" and somewhat delayed "UA" dived.  However because the aircraft must have seen us the cruiser does not come closer.  According to English information the presence of U-boats was "suspected".  
    21.41 GF 9391 Surfaced.  Cruiser no longer seen.  Went to the boats.  The people on the rubber rafts were taken on board on deck.  There are now 104 men on each submarine, in the cutters still about 200 men.  The cutters (5 each) are taken in tow by both U-boats.

    23.50   Redistribution is completed.  For this the V-boats which approached in the meantime gave good service.  Came to course 330°, speed 5 knots.  Intention is, to run towards the boats U-124 and U-129 and get as much distance from the sinking point as possible.  
        Crew is stowed away in the boat, initially up to 24 men must remain on deck in rubber boats.  In case of a crash dive the rubber rafts will be put off and remain with the released cutters.  
        In the boat room for all must be created slowly at first. The Artillery ammunition is thrown overboard to get the magazine free, torpedoes were reloaded.  Provisions stowed.  There is a huge rummaging in the boat.  
        The following Radio Messages were sent on several frequencies:  
        1)  19.00 hours,  PYTHON sunk by heavy cruiser at the supply point.  "UA"  
        2)  00.30 hours, With Merten square 9364, course 330°, 5 knots towing.  No losses.  "UA"

        2.)  With 11 lifeboats and 2 U-boats 14 days.  With 4 U-boats 104 men each also to Spanish port, if necessary home port.  With this prolonged diving impossible due to air supply. With lifeboats not sea capable and too slow.  Kmdt. Bruno asks return transit as soon as possible with four submarines without towing.        "UA".

    12.50   I decide to attack.  Let the boats go.  Rubber boats with 70 men put overboard.  (Were taken in tow and on deck by U-68.)  
    12.55   Set off, cannot maneuver ahead for a long time because I cannot leave the boats too long with Merten.  
        The enemy seems to approach quite favorably on general course 300°.  
    13.07 GF 6112 Dived.  Closed the enemy on about course 145°.  
    13.28   As the enemy comes in sight in the periscope it was determined that the general course is westerly after all.  About 270°.  
    13.30   Ran towards the enemy on course 210° and later further up to 250°.  In so doing ran a total of 24 minutes at AK.  
        Enemy zig zags between 330° and 210°.  Therefore UA only gets closer slowly.  
        The steamer comes closest on his course of 300°.  
        Range however was not under 3000 meters.  
        Also the target angle on this course is as much as 90°.

      Steered course 270°.  Attempted to get ahead at AK on the general course while the enemy zig zags.  Gained little. 
Indeed, while the target angle is sharp again the range threatens to increase.   Therefore when the enemy is again at target angle 330°, attempted to get even closer on course 250°.

        to shoot a 3-fan, although a G 7 a had to be included.  
        Enemy held his course until 6 minutes after the shot, only then turns within the framework of his zig zagging to course 250°.  
        No hit!  Miss!   
        Almost unexplainable.  Torpedoes were recharged the day before, must therefore reach despite the high shooting distance of 3200 meters.  The spread width covers a target from 7.6 knots to 10.3 knots, without consideration of the target length.  Target angle was exact.  
        The steamer sighted the G 7a, then he sent an SSS-report with position (received by U-68).  Apparently he did not evade.  When he turned the torpedo was at 5500 meters, however the shooting range was only 3200 meters.  
        Believe it was English "CLAN MACMAH or CLAN MACMAN, 6076 tons out of Glasgow.  
    15.18   Came to course 45°.  
        A new attack must be cancelled, because the shipwrecked cannot be left alone any longer.

                                                                Eckermann.  
        2.)  From 13.15 hours bearing signals by U-68 and from 17.45 hours by UA.  
        According to his statement Clausen had passed by astern and had only found the formation by bearing signals.  
       

The crew was distributed such that the "Ship 16" people are stowed on the submarines in the final form. "PYTHON" crewmen were put into the cutters.  They will later be placed aboard Mohr.

 
        About 19.00 hours transfer of the shipwrecked and corresponding provisions is ended.  Continued to advance with U-68 and U-129.

      The behavior of Mohr is completely incomprehensible to me.  He brings the entire rescue operation in danger, first by the fact that food and water rapidly decrease with the useless waiting and now that the 48 hour-long bearing signal sending in this wide sea area must bring the enemy.  A position message from him would clarify the situation immediately and allow appropriate measures to be taken.  It almost seems as if he has not manned his radio station for days.  
      It is with this operation further disadvantage, that the messages given on the various frequencies of the boats by the B.d.U. are not all repeated on any area frequency.  So there is no overview of what happens to all the individual boats, how much fuel they have, where they are etc.

1.) The Southern area at and west of Cape Town appear very promising.
2.) In the Southern area U-boats operating together or positioned together must ensure reception by day on one shortwave receiver even if Control is not heard so that a quick message exchange in urgent cases (for example KR messages) is ensured.  The use of all suitable frequencies for communication with the B.d.U. remains unaffected. Though the B.d.U. Radio Center repeated all appropriate Radio Messages from the Southern area on the area frequency. For the U-boats, it is always beneficial, and in my opinion, also important to be well informed as possible about the other boats in the area.
3.) Supply Ship.  The outfitting was advantageously carried out by a B.d.U. service center, and not by the Supply Ship Organization. Despite best intentions this is too rigid. (For example, "PYTHON", although coming from southern France and equipped with with refrigeration, had no fruit on board.  The Captain complained about lack of information before the trip. Supply and meeting place must be far apart to avoid surprise in case of compromise.  For this purpose, the individual supply operations must be well separated.
          The hoses etc. still have to fit better and be provided with quick release fittings. Currently the making and breaking of the seals takes much too long.   Important for surprises!
4.) Inflatable boat.  The large supply rubber boat of "PYTHON" was taken and proved itself excellently. It is proposed to equip all U-boats and store the boat in a quick-to-use canister on deck.

                         on the Kriegstagebuch of "U A" from 31.7. - 25.12.1941.  
                         -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-  
     
                   The Kommandant had shown on his previous patrol little luck and skill, which in part explains the failures.  
                  - Sustained bad luck with all offensive operations is improbable. - If for example on this patrol, the commander decides to attack a steamer sighted during the rescue operation, then it is obvious that this attack is only undertaken if the situation is favorable for it.  Not however, to refrain from maneuvering ahead so as not to leave the boats alone so long.  At sea state 1 to shoot a 3-fan in which 1 Ato is included, plus a 3000 meter range where the enemy is certain to see the bubble track, is seen from the beginning as having little chance of success.
