        Course for the two last shots:  65°, 1 hit, running time:  2 minutes 10 seconds.  
        Three steamers sheer out immediately and are in a sinking condition, one starts to burn.   
                                                       A fourth steamer was torpedoed, lies deeper forward.  Sinking likely.  Two of the sinking steamers are 6000-7000 GRT, the third 3000 GRT.  The torpedoed steamer was medium tonnage.  In total 3 steamers sunk, 1 torpedoed with a total tonnage of 14000-18000 GRT.  
                                                       One hour long very many star shells, that illuminate the battlefield bright as day, despite this I can set off unnoticed on the surface.  
    04.00 CF 7397    
    04.12  

Outgoing Radio Signal (0331):  Enemy convoy in sight square CF 7385.  The reported convoy consists of 15 vessels, enemy steers 180°, enemy runs at 8 knots.

 
                                                                       - Witte -  
    04.27   Came to course 210°, hope to have the convoy again on this course in 2 hours.  
    05.10 CF 7631 Convoy in sight again bearing 210°, 3 nm away.  Clear night, however very dirty horizon.  
      I attempt again from the east to advance on the flank.  In so doing was noticed by the port forward escort, which could not possibly have seen me, since the corvette could hardly be seen in the binoculars by me. Suspect radar, exacty as with the astern escort in the first attack.  
    05.33   In the searchlight of the corvette, about 1000 meters away, artillery fire.  
    05.34 CF 7634 Crash dive.  At depth A -20 the first depth charges.  
    05.36   Incoming Radio Message (0459):  To Witte:  Attack free tonight in favorable shooting opportunities.  At lightness continue transit, after that report position.  No convoy operation.  
      Tough luck, if I had the radio message in my hands a few minutes earlier, we would have been spared the depth charge blessing that followed.  
    07.05                                                 Up to now 45 well-placed depth charges from 2 corvettes, which have us "properly" in the gear with good localization conditions.  Minor failures.  After a new approach ran off for 10 minutes at GF, by this I get free.  From now only still distant scare bombs.  Detonations all lay over the boat.  Average depth of the boat:  A +75 meters.  
    08.00 CF 7634    
    12.00 CF 7636 Day's run:  = 189 nm  = 15.8 nm  
      φ = 36°34'N, λ = 22°38'W    
    14.00 CF 7386 No propeller sounds for an hour, Asdic impulses were fainter, therefore: surfaced.  All in all the convoy operation was a beautiful baptism of fire for the young crew.

    14.45                                                  On transit to the west passed an enormous wreckage field with many lifeboats and rafts.  The smallest boat carried the name "MONTENOL", (Steamer "M O N T E N O L" = 2646 GRT).  Four further boats were examined, of them 3 of the same type.  The last 4 boats were equipped for 36 personnel each.  The boats originate from the convoy operation, the wreckage field confirms therefore, that at least 3 steamers were sunk.  Judging by the size of the lifeboats, as was also observed, two large and one smaller steamer were present.  
    16.00 CF 7386    
    18.17   Outgoing Radio message (1805):  Naval square CF 7355 5 hits on 4 steamers.  3 steamers left sinking, 4th steamer sinking likely.  Total about 14000-18000 GRT.  Depth charges.  My position is naval square CF 7344.  9 + 8 torpedoes, 200 cbm, NW 1, high pressure weather conditions.    - Witte -

                                                       With the last zigzag there is no shooting opportunity for me on the steamers, therefore I attempted to shoot the starboard flank escort.  
                                                       Destroyer continually had target angle 0°, even at GF I cannot get out of the way.  The destroyer intermediately turned towards.  Therefore I must assume that somehow he noticed me. Despite this I remained at periscope depth, because he slowly wandered astern at the very end and I still hoped for a chance to attack.  However he passed at high speed 150 meters astern and shot at my periscope with artillery turning at the same time for depth charge attack.  Now I went deep at AK, no more shots fired.

                                                       Because the escort is ahead to starboard, I attempt to attack on the starboard side.  The escort runs at listening speed, 8 knots.  From 3000 meters range Asdic sounds area heard clearly.  The escort is a no destroyer, instead an American gun boat of type "ERIE".  The gun boat already has target angle 100°, range 2000 meters, when suddenly it goes to high speed and runs towards me at target angle 0°.  
    15.18   I can still get a shot off from tube III, in fact on the first steamers, that however missed due to an avoidance maneuver.

    23.57                                                  Since I am still a bit close to the flying boat to be able to stay on the surface unseen, I make a short advance in 20°T, where a suspicious smoke shroud was observed.

    03.31 EL 2326                                   If I am still to shoot, this is the last chance, because I have inaccurate navigation and do not know how far I am from the coast.  In addition, the escort makes such restless movements, steams up and looks to both sides. So I take the next favorable moment to initiate attack.

      Despite exact data all missed.  By my observation and also observation of the other officers of the boat both steamers stopped after the shots were taken, while the gunboat went to high speed and the steamers circled.  
                                                        The movements of the vessels lead one to suspect am under water locating or listening of the shots.  
                                                       Another approach is no longer possible due to the proximity to the coast.  "Colon" cannot be far away, then ahead to starboard, the sea sector is searched every half hour by a powerful searchlight.  That was a day with a lot of work and much bad luck!

    02.25                                                   An escort vessel, behind two steamers in broad echelon.  Course 310°.  The escort vessel is a destroyer and it is already noted while closing that both steamers are very large tonnage and are fully loaded.  The night is very bright, the water is an absolute, silvery, mirror duck pond, only the horizon is obscured and is constantly illuminated by very bright Summer lightening.  
                                                        From my experience the previous day and with these weather conditions for me, only a very careful approach and an attack from aastern is in question.

    04.00 EL 2261                                    The first approach failed, at enemy target angle 130° I am still 4000 meters away.  I broke the approach off, today I only want to shoot with very certain data.  By plotting the convoy has increased speed from 8 to 11 knots.  Occasionally the forward ship Morses with the destroyer, one stills feel pretty safe around Colon.  Since I can clearly convince myself of the size of the ships in the Summer lightening, I intend to shoot a double shot at each steamer and have the depth changed from 3 to 4 meters.  Despite yesterday's disappointment, I am daring this big torpedo expenditure again, these steamers deserve it.

    04.48                                                  Three high explosion clouds, the forward steamer shows a list and settles deeper aft.  The other shows at first only a list.  Both steamers shoot emergency signals, the destroyer comes about and goes in the vicinity of his mortally wounded charges.

                                                       In the first hour of the maneuver ahead I can determine that the steamer zigzags unusually, over 60° to each side, by which his general course changes slowly to the west.  For me that means the outside curve and I can only close slowly.  Several times the steamer passes out of sight in thunder showers, and I can only find him again by energetic pursuit in the direction of the bearing.  In the evening twilight I am on the bright horizon again and lose the steamer in a dark thunder cloud bank.  At this moment it came to a southerly course.  However after half an hour pursuit at GF I am suddenly ahead of him.  Because he also zigzags so strongly at night it takes a very long time to finally get in a favorable position for a stern shot.  But I am patient, he must get within a range of 1000 meters!

        Hit forward 30 meters and 40 meters.  Forecastle was torn off, otherwise however no further sinking observed.  
      Boats were put to the water.  I circled the ship at close range, to gather exact data for the type.  It is a modern passenger freighter with 4 passenger decks, 2 raked masts and a short thick smokestack.  Aft there is a deck house.  If I had recognized it as a large passenger freighter during the approach I would have had the depth setting of the torpedoes changed from 3 to 4 meters.  
    04.31                                                  Because the steamer still lays calmly without settling deeper and artillery use promises little success due to the strong Swell,  
        Coup de grâce from tube III:  
        Shooting angle - 0°, hit center, range = 950 meters, 61 seconds.  
    05.13 EL 2184 Steamer sank over the forestem.  
                                                       6 boats were observed in the water, 5 fully occupied, with them 6 large rafts.  In the dark night the boats pass out of sight quickly, I still catch one and learn here that it was a ship of the "United Fruit" company with bananas from Colon to New York.  In addition to the cew of 84 men, there were 97 passengers on board. The name explanation was incomprehensible.  The name "SIXAOLA" could be heard several times from the many explanations with which I was content to get away from here for now. By detailed observation by me and also by the other officers the sunken ship cannot be the "SIXAOLA" pictured in the "Merchant Ships" instead a ship of the same Shipping Firm of type "ANTIGUA".  The observations match also with the photograph in the book.  I suspect, that here a name change from the Shipping Company and because the observations are unambiguous and confusion of such a gross nature is ruled out.  Nevertheless, until the final clarification of this case, I decide. until his decision to use the name "SIXAOLA" in the report, as this name is unfortunately my only "official" document so far.  
    08.00 EL 2158 Therefore:

                                                       The steamer is now by observation and bearing shift bow left target angle 20°.  I try to at GF to close and steady the bearing.  That works splendidly, then the steamer zigzags only 10° to each side, I can even gain some space and turn for the stern shot at a short distance.  I can see from afar it is a ship of modern construction with a far protruding bow and cruiser stern.  With this sharp stem yhe speed is very difficult to estimate, however by submerged plotting he must run 13-14 knots.

      beautiful ship, perfect for torpedo firing.  It is a modern about 7000 GRT size tanker with a canon on the stern.  An attack with artillery would be pointless in this weather, because a modern armed tanker driving in ballast would only smile slightly at this attempt - so I have to let him run with a heavy heart.

    02.45                                                  Artillery permission to open fire, range = 800 meters.  Luckily, the first shot is in the bridge.  Steamer turned hard away immediately and returns fire.  It's really uncomfortable, especially at this short distance.  I also turned away at GF for the first time when he continues to fire in rapid salvos.  Gradually we find ourselves on the opposite course, but at twice the distance. I can no longer use the 3.7 cm without a sight. After about 10 minutes, a lucky hit goes into the aft deck house.  Due to the developing smoke, the steamer is very handicapped in shooting, that encourages me to stick with it, although he had already shot in damn well.  Even now he continues to shoot despite the obstructed view, only the impacts are less precise.  When his superstructure began to burn, he gave up the fight and launched boats, and ceased fire. Soon the ship will be on fire and then I also cease fire.

I took the steamer up to the last moment a Spaniard, because it has lowered the side of the hull at the level of the cargo hatches  
    17.28   I surfaced next to the steamer, because I could observe at close range that I had no neutral vessel before me.  
    17.30 ENE 5-6, Sea 4-5, medium Swell First salvo.  The men at the cannon don't have it easy in this weather, but our opposite isn't firing back, so I can proceed  
      very cautiously. Nevertheless, two men were knocked out of action by the sea in their belts.  This small steamer is much tougher than his larger brother yesterday, although there were more than 70 hits in the belly out of 100 shells, it hardly lists.  The crew had already abandoned the ship after the first salvos.  
    18.10                                                  Secured the cannon.  Steamer starts to burn and and since there is not a word to be understood in this sharp wind, let one man come on board.  This man writes everything worth knowing without even being asked.  It is the Yugoslavian  
              freighter:  
        "ANTE MATKOVIC" of 2710 tons.  
        Cargo:  Coal from Norfolk for Trinidad.   
    18.36 BC 8523                                  Steamer sinks over the forestem.  Until the third salvo he transmitted an emergency signal.  That was a tough but nice end to our series of sinkings.  But we are still proud of our remaining 17 shells!

    20.47                                                  Dived.  On getting closer one sees that it is a large, fully loaded tanker, but unfortunately is seen to have a cannon aft.  Despite this I decide after long deliberation to attack this tanker on the surface with artillery, because it is too difficult to let such a whopper pass idly.  
    22.00 NE 4-5, 5/10, Vis. good, medium Swell Surfaced.  Cannon ready!  
      Unfortunately it turns out that of the 17 shells in the readiness
      containers only a few of them still work, most of them did not survive the depth charge prosecution.  However these few have the desired effect, the first boat is launched.  The tanker transmits avidly, however does not shoot back -- so carry on!  Now only impudence helps!  At range = 800 meters the 3.7 cm comes into action (without sight), occasionally the 2 cm helps.  Success:  hardly any hits but the tanker stops and sets out the remaining boats.  Now I have the bridge shot on fire at close range, the waterline is too difficult to hit in this swell.  Soon the bridge burns, and I hope, it will burn out and lead the cargo to explode.

        A loaded 10000 ton tanker is always worth the full commitment!

                                                 After "anxious" 20 minutes of waiting, the rubber boat with the demolition squad comes back.  Detonation of the explosive charge installed in the ship bottom of the engine room.  At first the tanker settles deeper aft quickly, then however still floats quite a long time on its cargo, even when only the bow of the vertical ship is jutting out of the water.
