    12.22 DH 2179 Steamer in sight bearing 280°T.  Due to unusual lighting conditions, gained the impression that the target angle was bow right 20°, assumed enemy course 340°.  In reality target angle was left 20°. As a result, while contact keeping we have the impression as a result of strong shifting due to passing speed, that he constantly turns off to port because of the increasing target angle. Actually the steamer steered a straight course. When the picture becomes clear from plotting that [we have] the wrong enemy bow the steamer disappears in a rain squall.  
        Because of the straight course, size and white superstructure with colored smokestack the steamer 4-5000 GRT, is probably a neutral.  Search course unsuccessful.

Commentary of the Befehlshabers der Unterseeboote

 
                             to the Kriegstagebuch of "U-604" from 9.9 - 5.11.1942.  
     
                  Given the duration of the enterprise the success is gratifying.  
     
                  Specifically it is noted:  
                  The independently proceeding tanker at an estimated distance of 3500 meters was shot at needlessly.  Tough ones persist and strive for favorable shooting positions.  
                  On 30 October after coming in sight at 08.59 hours the convoy should have been marked for day attack.  Due to the comparatively weak screen the boat would still very likely be able to attack one more time at night.  
                   On finding the convoy again, as well as when losing it, it was only reported: "Convoy in sight" or "Lost".  Information on the location, course and the speed must be reported at all costs.  
                  The sinking on 27 October of the tanker estimated at 9000 GRT concerned "ANGLO MAERSK (7705 GRT).
