    12.31 BE 1229 Steamer in sight bearing 342°T.  Bow left, target angle 60°.  Turned away hard to port, steamer put astern.  Enemy comes out very quickly.  
        Came to 2 x GF.  Enemy general course 205°.  Slightly irregular zig zags.  By plotting steamer runs 17.5 knots and is as fast as the boat.  Despite 600 Amps assistance per shaft the bearing continues to decrease, from 330°T at the beginning of the chase to 310°T at 17.30 hours.  Boat gradually falls astern.

  Steamer makes a general course change and runs against the medium-high SE-swell.  In so doing loses about 1 to 1.5 knots.  Bearing steadies and very slowly the degree of E-supplementation is switched off due to [battery] capacity the boat slowly begins to gain ground again and with progressing twilight approaches.  
         
         
         
    19.00    
    19.35   Steamer at target angle 0°.  Course 170°, speed 16 knots.

    20.07   Turned for bow attack.  
    20.12   Bow right, target angle 30°.  Steamer zig zags towards the boat with target angle 0°.  Boat runs at range = 3000 meters at LF ahead of the steamer.  
        With 2 x GF run to the port side.  
    20.15 BE 1739 Attack with stern torpedo.  At range = 800 meters.  Hit under the bridge.  
    20.18   Steamer settles.  
    20.20   Steamer rises up sharply and sinks by the bow.  
        Enemy was a single smokestack passenger steamer, turbine propulsion, cruiser stern and sharply raked forestem.  On the stern apparently a disguised cannon.  Dark gray paint over all.  From bridge to stern continuously running superstructure.  3 decks.  Very similar to the American type Brazil, Argentina, Uruguay.  Estimated at 12,000 GRT.  Approached the boats.  By the consistent, independent statements of the crew of 3 rafts, size 16000 GRT.  
        Name remained unclear despite repetition and repeated spelling.  Spelling "C E O U I" or similar accepted.

Commentary of the Befehlshabers der Unterseeboote

 
                             to the Kriegstagebuch of "U-604" from 3.11. - 31.12.1942  
     
          The Kommandant acted skillfully during the pursuit and sinking of the fast runner on 2 December.  In contrast, the boat ought to have achieved success during the operation on the convoy from the 8th to the 12th of December.   The boat had contact quite often, had opportunities for success several times and should not have failed to attack only because of unfavorable attack conditions, brief forcing off by a destroyer and continuous diving only for detections.  Opportunities at the convoy are rare and must therefore be utilized whenever possible, even under unfavorable conditions.  
  Recognized success: 1 ship of 12000 GRT sunk.
