        The harbor is like a "duck pond", only large sailing vessels are distinguished.  In the center there is a patrol vessel at the terminal.  Mines are deployed according to plan, the first at 00.48 hours, one lies exactly in the channel off the barrier.  
        Mine laying on the surface would be impossible because a searchlight often illuminates the entrance at irregular intervals.

then over the stern at the 60 meter distance.  Deployed the last three TBM greens in the channel which was between 12 and 17 meters deep.  Last mine at 01.09 hours.  Total laying time 21 minutes.  Boat can be held while moving astern very well if it is exactly balanced.  The same at AK reverse, which was required by the barrier and presented no difficulties to the Engineering Officer.   While moving astern the boat must lie absolutely on an even keel, because otherwise it cannot be held in 12-17 meters of water.   For this purpose trimming is best done with soldiers.

  Ran submerged up to the entrance of the Grand Cul De Sac Bay.  Turned.  After the searchlight from Port Castries had shined, surfaced, so that the conning tower hatch was just clear, to locate the steamer, despite approaching to within 800 meters, nothing is seen.  The moon is in the west, so that our silhouette is easily seen from land.  Further penetration of the bay in darkness is not possible, because there is very little water, and the channel is very narrow.  At the illumination of the searchlight again dived and moved off.

    00.40   The second torpedo was shot at target angle = 90°, target speed = 9 knots, range = 1000 meters, depth = 2 meters.  
        Hit at the aim point aft 10 meters, heavy detonation column, apparently at the same moment a boiler explosion.  Steamer settles deeper aft.  Cannon was made ready and aimed at the periscope and rod antenna.  Steamer does not transmit.  After 37 minutes the bulkhead to the cargo hold breaks.

The steamer rights itself briefly and sinks quickly over the stern post.  Steamer is like "ALANMOOR", on the forecastle a sprit for mine search gear.  Has noticeably a lot of rafts in the rigging both fore and aft.

        Target angle misjudged.  Target angle is very broad.  Misled by the sound bearing growing larger.  
        Because steamer runs off exactly in the direction of the sun it is difficult to make out in the periscope. Steamer bridge and smokestack are still above the horizon.  Suddenly out of sight, in the sound gear nothing more is heard.

        From his statement "REZEWIE" 766 GRT, piece goods from Para-Brazil via Trinidad for New York.  Radio room, bridge and cannon position with 2 inches of armor.  
        I do not believe the Captain, because the steamer by the running time of the torpedo and the width in the periscope measured only 60 meters, while the "REZEWIE" is over 100 meters long.  Also a perfect coastal steamer would not have such armor and equipment.  Hold steamer as a 1500 - 2000 GRT motor ship.

        Steamer is Swedish "PEIPING", had painted out national colors and name.  No flag.  Because it is not on the list in accordance with Standing Kriegsmarine Order B.d.U. No. 105 and proceeding dimmed at night, will knock off.  Due to low fuel inventory, confusing installation of sun sails on the central and quarterdeck and proceeding dimmed, I decide on an attack without warning.  
        At target angle = 90°, target speed = 12.5 knots, range = 800 meters, depth = 2.5 meters.  
    15.28   Double shot from tube I and IV.  Hit after 69 seconds 2nd shot missed, because steamer was faster than estimated.  Steamer stops.  Slight list.  3 boats to the water, 2 set off, 1 remains lying alongside.  Due to tarpaulins and awnings the upper deck cannot be seen. Therefore, did not surface.  Also crew members still are aboard which can barely be seen.

        Ato had water in the engine chamber.  After 183 seconds a dull detonation was heard in the entire boat.  Because there was no running track, only bubbles in a location and running was heard up to detonation, the torpedo was probably a ground runner.  
        Steamer settles however does not sink.

        Today he soils his bunk and the living space; afterwards I had his comrades wash him.  In the conning tower Keller again has a seizure which appears very much feigned to me.  After one or two minutes Keller was again in condition to give normal answers and come down, albeit with outside assistance.  
        Since I have no means of combating such illness on board, I decide to proceed to the supply space at high speed in order to get to a doctor as soon as possible.  
    20.20   Radio Message (Serial No. 269):

        During the sending of the Radio Message Keller was again cared for by the First Watch Officer and Engineering Officer.  In this connection, Keller made a statement to a comrade that he only feigned the seizure to get back at his comrades.  
        After the Engineering Officer reported to me, I gave him the order to interrogate Keller who now lies in his bunk.  This interrogation confirms my suspicion completely.  
        Because Keller has feigned these disease symptoms, the only serious sign is the fever of 38.5°C, I can save the fuel from Schnoor and me.  Therefore.  
    22.03   Radio Message:  1)  Arrival supply point on 14 September at 10.00 hours.  Bearing signals from 12.00 hours.  Serial No. 269 settled.

                       Comments of the Befehlshabers der Unterseeboote

 
                         on the Kriegstagebuch of " U-66 " from 27.5 - 29.9.42.  
     
  First war patrol of the Kommandant with a veteran boat.  The very good performance, in which the mine task is especially highlighted, brought a gratifying success.
