    03.02.42 South of Newfoundland, Cape Race    
    00.00 BC 4448 Approached close off Cape Race, believe it is hopeless, because I suspect that if traffic still runs at all here, which does not seem to be the case according to the latest Radio Messages of the other boats, it will not run close to shore due to the poor visibility conditions.   Also as a result of bad weather the past few days I have no exact navigation fix,

    continued      
    03.02.42   so that also without the sounder one can form no picture.  For the most part, the difficulty of U-boat navigation results from the fact that not every opportunity to shoot stars can be exploited.  Increased cloud cover often occurs in the morning twilight hours in the northern latitudes, then returns again especially at night.  The creation of a sextant with an artificial horizon for observing would suit this fact and ensure even more accurate submarine navigation. The presence on different boats of a bubble sextant is a start and further development must be accelerated so that it can be operated on a rapidly moving platform.   The still prevailing bias among the navigators would then be easier to eliminate.

      NW 4, Sea 3, Vis. medium to good    
    20.00 BB 8375 Icing was heavier.  Therefore I gave up my advance in the Gulf of St. Lawrence, because the boat is no longer fully ready to crash dive (icing of the diesel air head valve and danger that the vents for main ballast tank I and V will also ice up in the calm seas.

    05.45 CB 2659 Light in sight bearing 330°T.  Turned towards it.  Attempt to close from the moon side of the steamer.  Steamer makes little speed, but turns. Tried to break through behind the stern and approach from the other side.  Steamer turns from the previous North Course to the NE and at the same time increases speed.  Despite maximum speed I can not keep up.  Steamer has a great many lights set so that it can not be identified.  Let the steamer go, because other boats already reported an illuminated U-boat trap here.

        Close up and shoot this time with machine guns the stern and bridge.  Nothing stirs.  The tanker is completely abandoned.  Rubber boat launched, to determine if the tanker has diesel oil for supply on board.  However, what is found is completely unusable because it is very thick and must first be heated to atomize.  
        Sought after secret documents, but the lockers were empty. Found that tanker was proceeding from Montreal to Venezuela. The tanker was armed with a 10.2 cm cannon on the stern and a 4 cm antiaircraft gun on the top deck, but no ammunition was found. 4 explosive cartridges were places in the engine room. Despite this the tanker did not sink.  With a total of 98 8.8 cm shots

Own damage: Forestem pushed to starboard about one meter so that the starboard tubes can not be opened.  Tubes I and IV flood from overboard, tubes II and IV will not open due to bending of outer tube door fairings, watertight bow can not be closed.

Shot from range = 700 meters, depth 3 meters, with tube V.  Miss.  Speed somewhat overestimated, torpedo must have passed barely ahead of the bow, given that fell astern.  It was a small 2500 GRT British freighter of the 3 Island type.

        In the twilight surfaced, maneuvered ahead to target angle 0° and moved off a bit.

Dived.  Surfaced when the tanker was abeam, at a range of 1500 meters and began artillery combat.  Tanker was armed with 3 cannons.  Running battle with E-supplement [use of E-motors and diesels together].  The tanker turned away after the first salvo and shot repeatedly with his stern cannon.  His first impacts were short about 200 meters.   With the help of the E-supplement, his subsequent shots, as usual with the English, were on the short side

        Own impacts were all far, although after the 7th shot a range of 0 was set.  By procedure the First Watch Officer allowed no short shots with the top gun sight. Only at a distance of about 500 meters was the first hit achieved, but also the ammunition ran out.  
    21.30 CB 4796 Must let the still shooting tanker go.  
      A later examination of the range wheel revealed that it had shifted by 6000 meters against the graduated rim, while still stuck so it couldn't be moved, not even by force. During shooting there must have been a continuous maladjustment, because upon departure from the base graduated rim and range wheel rim still matched and were checked by witnesses.

Because the weather is favorable, I decide to download the stern torpedo [from the upper deck], to have at least one tube ready to shoot.  Unfortunately I can not get to the outer tube doors of the forward tubes because the boat pounds too heavily in the swell.  The downloading was just possible in the seas.  The crew worked well and despite the dark night the transfer gear was assembled correctly and properly.

CC 2543 

Shot with tube V.  Miss. Passed astern, because the coarse needle of the torpedo shot angle receiver indicated 10° too low.  In the periscope it was also observed that the torpedo steered to the left with a shooting angle of 186°.  
        [the shot angle of the torpedo was 10 higher than set on the lead angle calculator]  
        With a new check of the system the same discrepancy was very rarely seen again, so it was not discovered during the daily check of the stern tube by the operators.  In addition, the match light was illuminated despite the mismatch of the coarse pointer system, thus preventing the discovery of the defect before the shot.  When the shooting angle was compared to the angle at the tube before the shot it agreed with the result on the lead angle calculator.  The error is still unexplained.

                              Comments of the Befehlshabers der Unterseeboote  
                              on the Kriegstagebuch of "U-564" from 1.11.41 - 6.3.42.  
 
 
 
1.)        The patrol had to be broken off early because the outer tube doors were not operable due to the ramming with "U-107"
2.)        The ramming was the result of incorrect behavior of the Kommandant during the approach of both boats.  As a result he spoiled the great success that might have followed.
3.)        The demolition of ships promises the greatest success when the explosive charge is mounted on a line outboard below the waterline of the ship to be blown up.
4.)        The requirement to create a usable U-Boat sextant is known. So far, however, all such attempts have been unsuccessful.
