    12.50   The north coast of Iceland comes in sight to port.  
    13.32   Kolbeinsey Island bears 215°T.  
    13.52 AE 1686 40° to starboard a steamer in sight, 8 nm away.  
    13.53   Dived.  
    14.05   To Action Stations.  
        Steamer emerges from the haze to the north totally out.  Dived, because the boat is positioned on the clear horizon.  Steamer initially has bow right target angle 50°, then turns to bow left, zigzags about 30-50° about every 7-9 minutes, estimated speed 10 knots (see sketch).  
        I run on converging courses to the zig zags at GF and HF, showing the periscope at KF, and approach the enemy to a target angle of 70-100° distance 2000-2400 meters (6 x magnification 15-17° in the periscope).  Did not shoot because range is too great.  
    15.22   Secured from Action Stations.  
    16.00 AE 1923    
    16.05   Steamer passes out of sight bearing 70°T.  
    16.15 Vis. good, W 4, Sea 3, 1023 mb Steamer can no longer be seen.  Initially I pursue on course 70°, then on general course 100-110°, on course 100° at GF.  However the steamer does not come in sight.  I believe that the steamer is a patrolling auxiliary cruiser and come  
    19.00   to course 0°, to possibly meet him on this course.

        Appearance of the steamer:  
        A passenger steamer with one canted smokestack and 2 canted masts.  Estimated 8000 tons.  Superstructure light gray, hull dark gray.  A crow's nest in the top of the forward mast.  It may have been the English auxiliary cruiser "ALAUNIA".  Armament could not be distinguished (backlit).  It must have run at a minimum of 13-15 knots.

    15.00   Large ice blocks (5-10 meters high) to starboard 5 nm away.  
    16.00 AD 2962 Searching squares AD 29 and 52 on the intended search courses was not possible due to ice in the NW half of the square.  Searched the SE half of square 29 and 52 up to the ice limit and square 53 to about 10 nm of the coast.

      Overcast, Vis. changing, wind calm, SE, 1025 mb    
    01.20   Vessel in sight bearing 250°T.  It looks like the superstructure of a large vessel coming over the horizon.  Apparently at very low speed, because the bearing does not shift.  
    02.15   Dived, to identify the vessel submerged.  In the periscope nothing can be distinguished.  
    02.30   Surfaced, to take a new bearing.  Vessel lies bow left about target angle 20°.  
    02.30   Dived, to close submerged.  
        After a while the vessel comes in the periscope, was smaller and smaller and turns out to be a large fishing trawler with 2 masts (mirage).  
        Moved off submerged on course 270°.  Vessel passes out of sight.

        Because the shallow depth is not noted on the chart and the depths given on the chart are uncertain, I decide to surface.  
        All around sweep is clear, the visibility is somewhat worse.  
    04.41   Surfaced.  
        While blowing the visibility suddenly improves, so that the fishing trawler is again in sight 2-3 nm away.  Initially he towns towards, then slowly to the coast and runs off.  I must accept that I have been sighted.  Therefore so that the presence of the boat will not be betrayed, I decide to sink the fishing trawler.  
    05.15   Fire opened.  
    05.30   Vessel sunk with artillery.
