    11.00 CA 7635 Put the boat on the bottom at a depth of 30 meters.  In spite of 17 tons negative buoyancy the boat works very strongly on the bottom.  With the sea from this direction and with this strength one must find deeper water.

    03.10   Boat rose from the bottom.  I intend to round the buoy to the south of "Currituck-Beach" to the north and then to run closely under the coast to the next buoy to the south.  To go from there to the east, dive when it is getting light and run submerged to find out whether north and southbound traffic runs between land and the 200-meter line by day.  
    04.00 CA 7637 3 shadows to port.  It is a coast guard cutter with 2 patrol vessels.  Course approximately 110°.  Apparently they continued on in port echelon.  Avoided to the north and continued to CA 7628 lower-center edge, then on the next buoy.  No traffic discovered.  Lights as in peacetime.  Went to CA 7691 on course 85°.  In CA 7668 lies an uncharted buoy.  I suppose that it marks a wreck.

        I intend to advance the next night to CA 7360 to position tomorrow submerged on the line connecting Hatteras-Winter Quarter light ship and to advance the next night to Cape Henry.

    02.26   I sent the following Radio Message:  During advance through naval square DC 2287 and in CA 8440 and 7600 nothing except a coast guard cruiser with 2 guard vessels in 7637.  Was not sighted.  Submerged by day.

    00.00 CA 8147 Surfaced.  Thick ground fog.  Under these circumstances an advance under the coast has no purpose.  Therefore, I proceed with 1 E-motor at KF on reciprocal heading.  
    03.55 CA 7366  
    06.00   The fog becomes little bit thinner.  The sky is clear  
    06.20   An aircraft throws a flare bearing 130°T.  Distance approximately 5000 meters.  Shortly after, the aircraft flies over directly ahead of our bow.  Even at night with fog one is not safe from those.  The marine phosphorescence makes it very unpleasant.  I believe from the aircraft one can recognize the boat by the shining wake.  
    06.55   It has cleared a little bit more.  
    11.15   It is very hazy weather with low-hanging clouds.  Therefore, I decide to proceed submerged due to aircraft.

    19.05.42   Radio Message from Gießler saying that his area, to the north of me also has no traffic.  I decide on the basis of the traffic situation off the coast, to ask the B.d.U. for another operations area to the south.  Apparently, the Americans have stopped the traffic and are waiting for the safety of bright northern nights.  The boats in the south report heavy traffic.  I still have 125 cbm and 7-weeks' provisions.  Also, still all torpedoes.  If I operate in the south, I can definitely get rid of my eels to best advantage.  If I do not resupply with fuel oil, I can stay amongst the islands until reaching 35 cbm.  If however, I resupply like Krech and Hoffmann, I can proceed to the traffic-rich area of Folkers and operate there.  
        Therefore I send the following Radio Message:  
        Nothing seen in naval squares CA 8721 via 8181 to 7366.  Alert air day and night. Very heavy marine phosphorescence. Request shifting operations area to the south.  
        Missing Serial Numbers 202-204 and 206 and 207.  125 cbm.  7 weeks' provisions.  Square 8145.

    01.13   Radio Message from B.d.U.:  Gelhaus free to maneuver to the south.  
        I intend to go directly to the south to operate there under and between the islands to the east if I get no resupply.  However, if I am supplied, to operate to the south of Cuba in Folkers area.  Proceeding off the coast of Florida is not promising on the basis of the messages of "U-98", Rasch and Suhren.  Also now, on the basis of the messages, the bright moon period arrives and operating off the coast is not very promising with the strong air surveillance.

    20.50 DM 2686 A steamer (tanker) on a northerly course in sight.  Maneuvered ahead to the north.  In so doing, was sighted by an aircraft at 23.40 hours and forced to submerge.  Aircraft flew quite high and was seen only as it approached.  Crash dive!  Still attempting to approach the steamer submerged.  Because target angle was only approximately 10-15°.  
    00.10   Again at periscope depth.  I do not spot the steamer in the periscope and, therefore, during the dive the steamer has turned away sharply, possibly to a target angle of 120° and a distance of 10000 meters.  Because he can see me, I dive again.  Besides, the aircraft still is there.  Therefore, I dive again.  I remain submerged until it gets dark and then surface and continue my advance.

Attempted to get to it however, it passes by out of range.  As I get closer I determine that the steamer I am operating on lies behind a tongue of land.  However, because he smokes so heavily, I hope that he will emerge soon and I position off the harbor moving back and forth.

      NE 2, Sea 1, 8/10, misty, Vis. medium    
    00.41 DN 7686 A cloud of smoke in sight directly ahead. Steamer's position is approximately DN 7922.  Bearing changes with observation so is not approaching us at target angle 0°.  As stack and masts appear, dived for attack.  Steamer is heading 30°.  Shot from tubes I and II.  Multiple independent shots.  Target speed 11 knots, target angle 90° and 96°.  
        Aim point ahead of after mast.  
        Hits after 25 and 31.5 seconds.  
      DN 7686 First hit at the forward edge of the bridge.  Second at the after mast.  Both with high tongues of flame and heavy smoke.  Afterwards the boat cut under.  Once the periscope was again clear after 1.5 minutes there was nothing to see of the steamer.  Surfaced.  Only an oil slick and some wreckage and a light similar to a night life buoy light sighted.  600 meter wavelength monitored immediately on surfacing, nothing heard.  
        Steamer was a normal cargo steamer, straight stem, lowered deck area [where the gunwale is at the same height as the deck], mast, high and quite compact bridge. Thin stack, quite close behind the bridge, there and behind it several lights and small masts, the stern mast, raised aftership.  I cannot give an exact description of the steamer, because I saw him only badly in the darkness in the periscope and only just before shooting could I see clearly.  I shot 2 torpedoes, because I could not determine the speed and could not determine the target angle exactly in the bad lighting.  I estimate him at approximately 5000 tons.  Topmast was similar to the "AMERICAN".  
        After firing returned to the old course, after 1 hour with 1 E-motor KF, because I hope to strike here even more.

    03.54 EB 2119 Shot on the surface from tube V, target angle 98°, target speed 10 knots, range 1000 meters, aim point smoke stack.  After 50 seconds a high explosion column with white smoke development between the fore mast and the bridge.  Steamer settles immediately forward and within a half minute sinks over the fore stem.  
        Steamer was fully loaded, had an extended Mayer bow, prominent lowered deck area [where the gunwale is at the same height as the deck] forward and aft, forward mast, very large bridge with long superstructure, for passenger transport, high smokestack, between smokestack and bridge [illegible word], behind the smokestack ventilators and small masts, after mast, high cabin with superstructure was however broad and very long.  The section between the masts does not fit at the shot.  Estimate him at least 7000 GRT.  Did not transmit further.

    01.06.42 EB 2113 They appear to be very fast, in spite of my high speed the range does not decrease.  At 22.28 hours a flying boat dives on us.  I give the alarm and want to attack the formation submerged.  Unfortunately, oil has run from the transmission of the rear diving plane into the motor, making it inoperable, so that the rear diving plane can be operated only by hand.  In the high swell and otherwise duck pond sea it will be difficult but must be attempted.  
      Wind calm, Sea flat, Swell, 3/10, Vis. very good  
         
         
        The boat can not be held on course despite all hands maneuvers and 1 motor HF, 1 motor LF.  The soldiers technique with the after diving plane is not as quick as is necessary in the swell.  We constantly oscillate between coming out and 25 meters.  The convoy consists of 4 medium-sized passenger steamers and 2 American 4 smokestack destroyers.  The speed amounts to 14-15 knots.  Because the boat can not steer at periscope depth I break off the submerged attack.  With the speed of 14 knots I can reach the convoy again in 10 hours at the earliest.  My diving plane will still not be in service by then and I must attack submerged due to the moon.  Therefore I let him go and repaired the motor first while submerged.  The motor must be totally removed and cleaned.  Hopefully it is not so heavily charred, that it has shorted.  I must remain submerged, because with the clumsiness of the boat the motor would be smashed and besides, the linkage of the hand drive must be temporarily removed because otherwise the motor can not be removed.

        Reports on the 600-meter wave "SOS, SOS de w u y r position lat 1947N long 8555W submarine torpedoed at 03.05.  
        "The call sign is not clear, it was also taken as w a y r.  
        After the hit the engine runs again and the steamer turns hard starboard.  After about 25 minutes the fore ship had settled such that water runs in the boiler room and apparently fire was extinguished.  After 38 minutes the steamer stands on its fore ship and goes quickly under.  
        The name of the steamer can not be ascertained on the basis of the radio call sign because it is not recorded in the book.  I estimate him at about 4000 GRT.  He was a normal freighter with two masts, lowered deck area forward and astern, smoke stack quite far behind the bridge.  At the level of the smoke stack on each side one small mast.  
        After the sinking ran off on course 0°.

    11.02   A shadow detected ahead bearing 30°T.  Looks like a patrol vessel.  Held on to get a better identification.  Was recognized as a sailing vessel.  Despite the beginning of twilight and the heavy air reported by other boats I decide to sink the sailing vessel with artillery.   He drives dimmed.  Therefore without warning.  He catches fire after the second shot.  He was loaded with a combustible liquid which burns and continues to run out on the water.  When the boat lies in flames up to the after mast, turned away.  Crash dive!! because a flying boat coming out of the dawn quite high is upon us.  Initially continued submerged.  In this area, heavy air is reported from the other boats.  I will continue transit submerged until Mona Island is well astern.

    08.15 DD 1117 [typo DD = DP] Shadow in sight.  Steamer on course 295°, very fast.  I run at 2 x GF and do not get ahead.  Initially with E-motor supplement I come slowly up.  His target angle is 100°.  Because as it is bright I must shoot soon.  Because the target angle is broad and I still have enough torpedoes I decide on a four-fan.  09.48 hours shot from tubes I - IV, target speed 16 knots, target angle 110°, range 3000 meters,  target length 120 meters.  I have deliberately set 3000 meters, so that there is no possibility that the fan will pass.  The range amounted to about 1700 meters.  Nevertheless passed.  I can not maneuver ahead due the beginning of dawn.  Despite this I will however hold contact until it is completely bright, perhaps he will change his course at dawn and I can still engage him.  However he stubbornly holds his course and speed.  I can exactly identify him as a steamer of type TORRENS.  
        I can not explain the miss.  Even if he had been 1 knot faster, which I now accept, or slower, my torpedoes would have to have hit.  A torpedo broke the surface after the shot several times.  
        Because the steamer held his speed, at 11.30 hours pursuit broken off and transit continued.

        When the radio message was sent, I did not consider the provisions transfer correctly.  Possibly I can receive a little more fuel from the tanker and remain a bit longer in this area and still get rid of my torpedoes.  Therefore I sent a follow up Short Signal:  
        Still have provisions up to the 15th of the next month.  Unfortunately the last character is not correct such that the signature comes out "U-124"  
    20.00 DE 1776 Because I must correct the signature of the Short Signal, I want to inform B.d.U. at the same time, that I want to delay two days in DD.  I sent the following Radio Message:

        After 4 minutes 30 seconds a hit between the super structure deck and after mast.  Ship settles aft deeper, however runs on at estimated speed of 13 - 14 knots.  I want to maneuver ahead and make another attack.  However it is slowly getting brighter.  The steamer sees me and angles itself a little bit closer and shoots at me at 10.00 hours with his stern cannon.  I give the alarm and dive.  After the hit the steamer transmits.  He is named "JAGERSFONTEIN" 10100 GRT.  The steamer proceeds at speed with wild zig zags and circles.  At one moment I am positioned favorably ahead of him to shoot however, with this duck pond the periscope is discovered by the numerous people standing on deck.  The steamer again turns away.  I am only surprised that he has not departed, but continues to drive in this area. Perhaps he wants to have calm water to take to the boats. Therefore, I go back to the attack location. The steamer is approximately 15000 meters away, when I reach the location.  I surface.  A lot of cotton bales float there but no boats. He has loaded cotton.  Shortly after surfacing the steamer reports that he taking to the boats, and abandoning the steamer.  He has also stopped and has settled astern a little bit deeper.  I go back to him and see that to port two lifeboats have gotten away.  I then dive and approach him submerged, at 14.59 hours from tube V a coup de grace to hit under the bridge.  High steam cloud, the ship settles deeper astern and sinks over the stern.  Surfaced.  4 lifeboats and a raft float about.  The lifeboats are heavily occupied also a number of women.  Approached close to the lifeboats.  Ran off.
