    20.12   Outgoing Radio Message:  1315/2/80  
        B.d.U. from "U-26":  Passed 45°N at 13°W.  Position when sending:                           φ =  44°10'N

    03.11.39 Atlantic, level of Cape Finisterre    
    10.00 W 1-2, W-Swell, clear, Vis. good Following radio message received on the 600 meter wavelength:  To All:  
        Bâtiment ennemi, probablement sousmarine par 43° Nord, 14° 20'West a 20.10 h le 2.11.position douteuse.  
                        O 100 / 3 / 11 Quessant Radio  
        The reported U-boat would seem to be us.  
        Bearings were probably taken on sending the Radio Message 1315 / 2 / 80.   
        It is thus proven that bearings are taken on all Radio Messages sent on shortwave and evaluated.  Error between the actual and bearing position:  
                        80 nm in direction 214°.  
        The 600-meter wavelength remains continually monitored as much as possible, because steamer reports, U-boat and mine warning reports can provide important clues.

    09.00   Boat put on the bottom on the "Bajillo del Tambor" Bank in 12 meters water to observe the harbor of Gibraltar.  The flat water requires the greatest caution.  The visibility is very limited.  
        Results of the observation:  
     

 

SE 0-1, flat water, Vis. good, fair, at times a bit misty

There are 3-4 destroyers continually under way observing the Strait and the Bay.  They stay mostly on the line South Mole Gibraltar - Punta Carnero and east of Punta Carnero.  Arrivals head mostly to the South Mole on course 30-40° and shortly before the entrance come to a northerly course.  Both entrances are utilized. Departing the opposite course.  In the harbor at the inner edge of the South Mole lie 3 cruisers each with 3 smokestacks (10000 tons).  Of these one with camouflage.  At the Center Mole a tender.  On the roadstead between La Linea and Palmones lie a total of about 30 steamers.  In the western part predominantly Italians.  In the rest English and French.  Many of them painted dark gray.  Armament can be discerned in a few.  Probably these are auxiliary ships or traps.  There was welding on the forecastle of many English and French steamers.  Apparently to bring armament on board.  
    11.00 - 11.30   2 modern destroyers run in with 3 steamers from the west.  
    11.45   One transport runs out to the Mediterranean.  It steers the following course:  Initially 200-210°, then 180° and finally turns to 40°  
      Wind calm, leaden flat sea, clear, Vis. good Due to my low height of eye the turn points could not be determined exactly.  The escort consisted of 2 destroyers.  
        Off the Center Mole outside the harbor lies a large Italian passenger steamer at anchor "OCEANIA" type.

    08.11.39   2 times the take off of a 2-engined sea plane (flying boat of older type) was observed.  Apparently these serve to guard the Strait.  By day find no net barrier off either entrance.  Whether the presumed net barrier lies to the west of the Center Mole cannot be exactly determined.  It is noticeable that merchant steamers coming out of the south entrance come initially to a southerly course, then move off on a SW course, after a period first turn to the north to get to the Roadstead.  
      Wind calm, leaden flat sea, fair, Vis. good    
        The minefield west of Europa Point seems to be in place.  The course of inbound and outbound vessels give rise to this suspicion.   
    21.40         "        "        " Surfaced and remained lying in position to ventilate the boat, compress air and pump the bilges.  The boat lies in front of a dark part of the bay and is probably not seen.  Completion of the mine task seems hopeless.  With the flat, calm water any approach would be detected immediately.  Due to the water depth the T.M.B. must be deployed approximately 100 to 200 meters off the Mole.  There, however, the periscope can be used only very sparingly even at night, because the illuminated city throws a bright glow on the water.  Continual fixing of the ship's position by bearings made through the periscope is not possible, because the entire harbor is awash in the glow of 1000 lights, however the Mole beacons do not burn.  Due to the current running there determining the ships position by plotting is not sufficient.  
      Brightly illuminated by the lights off Algeciras and Gibraltar Bay, starry clear night, no moon  
      Wind calm, leaden flat sea, Vis. good, starry sky, no moon, the Bay is well illuminated On the basis of Radio Message 1806 / 6 / 62 I decide not to carry out the fouling.  I intend to leave the Bay submerged and break through into the Mediterranean.  
    22.00   Dove again.  Held close to the Spanish coast on a southerly course.  Passed Algeciras.   
    22.30   In the conning tower suddenly a regular, very high chirping sound is heard.  The interval between the tones is 7 seconds.  The tone is very high and reminds one of the German S-gear.  In the listening gear nothing is heard.  Also some members of the crew are not able to hear it.  
        One has the clear impression that a bearing is taken because the tone comes from forward and runs over the port side to aft, the then again comes back.  At the same time I see in the periscope on the port side (260°R) a vessel with a top lantern and a green side light.

    08.11.39   The side lantern is positioned very low and far astern in relation to the top light.  We already saw encountered this arrangement in the previous night when seeing patrolling destroyers, which apparently wished to appear as fishing vessels.  
      Wind calm, leaden flat sea, Vis. good, starry sky, no moon  
        The vessel maintains the same bearing and range.  About every 5-10 minutes a group of bearing tones is heard, so that undoubtedly it seems that we have been located.  The destroyer to port stops and goes at timesly so that it is always abeam to port.  Therefore I turn to the Ensenada de Getares, where there are swarms of illuminated fishermen, and let the boat fall to the bottom in 29 meters water.  Distance from the coast is about 1 nm.  The bottom is rocky.  
                                                                
    09.11.39 Gibraltar Bay    
    01.00 Ensenada de Getares All auxiliary machinery secured.  The gyro compass was shut off.  Through the entire night up to 12.00 noon the bearing tone continued to be heard.  As before at regular intervals.  The heard vessel stops frequently and gets under way for a short time again.  Because of the danger of being heard, no air purification. Mouth breathing through potash cartridges.  
      No weather observation because submerged  
    14.30         "        "        " Boat raised from the bottom and carefully brought to periscope depth.  No patrol vessel is found in the immediate vicinity.  Unfortunately a few fishing vessels.  East of Punta Carnero there is a patrolling destroyer.  He seems not to have detected us, instead stays in his position.   
        rounded close around Punta Carnero and initially steered a westerly course with the current.  There is busy steamer traffic.  2 further patrolling destroyers  and one armed fishing trawler were sighted to the southwest and south.   
    17.00   Because we are apparently not detected, came to course 145°, to cross over to the African side.  The current sets to the east.  Course over ground 120°.  
    about 17.00 Strait of Gibraltar From the west a dispersing convoy runs in for Gibraltar.  3-4 steamers, among them 1 fat tanker, escorted by 2 modern French destroyers.  Range is too great to approach.  Both French destroyers run out again and exchange Recognition Signals with 2 English destroyers.  Letter "Bruno" is recognized.

    18.07 Level of Cape Falcon Surfaced after darkness and moved off to the north, to observe traffic under the Spanish coast.  10 minutes after surfacing an oval white spot is sighted.  Apparently marine phosphorescence on the side of a hull.  Since oil spills were also observed, and probably air bubbles, it may have been a dived U-boat that submerged ahead of us.   Before it had stood against a dark cloud bank.

        There is a lot of steamer traffic here.  Apparently everything going to the north passes here.  Course again set for Cape Tres Forcas, to observe there once more.  Up to now no convoys seen.

    12.15 - 13.15   Dived for a vessel bearing 100°T.  It turns out to be Alborán Island (!), which in the mist is easily mistaken for a steamer.  Strikingly light traffic.  
        I intend to stay further to the north during the night, to deploy periscope-decoys there and then begin return transit because fuel is already tight.  I want to be about 30-40 nm south east of Gibraltar early in the morning, remain there by day and surface and proceed to the west so that by moonset (about 23.00 hours) I am at Ceuta, to break through just off the African coast.  
        Summary of observations in the western Mediterranean:  
        Convoys were not observed.  They seem to run only west of Gibraltar.  On the African coast at Cape Tres Forcas up to Oran no steamer traffic.  The main traffic runs between Gibraltar and Cape de Gata close under the Spanish coast partly within territorial waters.  At Cape de Gata the route forks.  From or to Gibraltar north or south of Alborán Island only independent steamers run, among them those with westerly course dimmed at night.  So far scheduled surveillance does not seem to be carried out in this area.  Neither warships or aircraft were observed.  Vessels seem to be stationed in the Gibraltar area in limited numbers (no flying boats).

    19.45 NE 1-2, Sea 1, changing cloudiness, bright night, moonshine, Vis. good Shadow in sight bearing 330°T.  Was recognized as a dimmed passenger steamer of the "HIGHLAND BRIGADE" type (?) (14100 tons).  The steamer zigzags very strongly that it is thought he had seen us in the bright night.  General course about 160°.  Zigzags at irregular intervals between courses 100° and 220°.  
    19.54   3 torpedoes shot from target angles of 90°, 100° and 180°.  Three misses due to mis-estimating the speed on one hand and on the other by the strong zigzagging of the enemy.  Range at the shot about 2000-3000 meters.

                       λ =   11°50'W  
        Ran behind at AK with the intention of maneuvering ahead for a new attack.  However the steamer runs at 16-18 knots and maintains his zigzags course regularly so that he may not have seen us.  
    23.00   Due to lack of fuel pursuit was given up.  Additionally the speed advantage is too slight.  A pursuit, which would have taken all night, could not be permitted because of our limited fuel inventory, due to the southern course of the steamer.  After giving up the pursuit of the steamer came to most economical speed.  Diesel-electric both diesels LF, 5.3 knots through the water by railing log.

    04.12.39   It was already determined on the last patrol that the direction finder was no longer usable after 14 days.  The overhaul directed by N.E.K. identified a too weak spring tensioning device.  However the newly installed spring is not better.  Furthermore, submerged reception on very low frequency on the direction finder is not sufficient.  Reports on this subject had already been submitted several times by "U-26" in peacetime.  It is unusable in the present condition for wartime.  Experience reports and proposed changes are presented separately.
