Richard Bland was hit by one torpedo from U-255 on 5 March.  The torpedo did not explode and passed completely through the ship which remained in convoy.  On 10 March U-255 attacked Richard Bland again breaking the ship in two.  The stern section sank, the forward section was towed to Iceland and declared a total loss.
Note:  The positions in the table above and in the Google Earth patrol summary are derived from the KTB and in many cases do not match those set forth in authoritative references such as Jürgen Rohwer, Axis Submarine Successes of World War Two or the Uboat.net website.  The goal here is to present the picture relative to the U-boat and not the absolute position that the ship was attacked or sank.

        An own U-boat comes up at high speed from astern and turns away.  
    02.22   Three shadows astern to port.  
    I want to maneuver ahead for a day attack because I cannot get an overall view of the situation in the low visibility.  
    03.59 AC 4348 upper-center Outgoing Radio Message 0329:  03.00 hours convoy AC 4269 lower-left. Course 80°.  Detection 140 cm, horizontally polarized.  Weather.

        I just get the Radio Message out.  Then Crash dive for land-based aircraft from 90°T, 4000 meters away, course 270°.  
    08.56   Ran in to attack.  Was noticed by the screen probably in the wave troughs and apparently already at 1500 meters shot at or depth charges were thrown.  I cannot see where the always well-placed detonations come from.  
        Went to depth 2A meters, depth charges.  
        I attempt to go up again and still reach attack position, however at depth A meters well-placed depth charges again.  
    11.07/09   Ejected four Bolde and zigzagged against the seas to 250°.  All together 54 depth charges for us.

        A part of the detonations that we heard under water, must have come from an air attack, which we only learn of now, F.d.U. reports damaged ships.

        Must run off before destroyers several times.  Cannot see anything of the convoy except for these quite far offset escorts.  
    02.45   Radio Message 0109:  07.00 hours be in patrol line from square 6749 to 8342, Göllnitz, Reche, LaBaume, Queck, Timm.  
        Advanced ahead of the far offset escorts.  Did not get through the flank screen.  
    03.40   Outgoing Radio Message 0310:  Convoy AC 5697, speed 9 knots, course southeast.  Weather.  
    04.00 AC 5934 center It was already brighter.  I decide at least to attack a destroyer.  Ran as far ahead as possible and turned towards the screen.  Hound's curve on the starboard aft destroyer.  However, I do not get close enough at a usable target angle.  The steamer columns were now visible in front of the already brighter eastern sky.  Behind the destroyer there is now a gap.   
      NW 3, Sea 2, (mist) 10/10, -3°C, 989 mb, Vis. 3 nm, medium Swell  
    04.32   Two-fan tubes II and III on three overlapping steamers:  speed 9 knots, target angle right 70°, range 2500 meters.  However the range may have been underestimated; in any case it seems our cold Etos did not reach.  
        I can only run off, because it is evermore brighter.  In so doing I advance on a far offset destroyer, which forces us to go too far off.  
    05.11 Driving snow Outgoing Radio Message 0445:  Convoy AC 5935, course 140°.  
    06.20 AC 5965 center-left edge Have lost sight of the convoy.  Maneuvered ahead by plotting.

    06.52   Several escort masts come at us out of the mist bearing 100°T, about 10 nm away.  
    I suspect that the convoy has advanced into heavy ice and must avoid.

                    After a short overhaul the boat had a new opportunity to familiarize itself with the difficulties of the Norwegian Sea at this time of year.  To the aggravating visibility and ice conditions this time came especially stormy weather and strong defenses at the convoy.  With radar detection appearing for the first time with the uncertain visibility especially also uncomfortable at night.  It is therefore gratifying that, given the small number of boats and the limited use of the Luftwaffe at least on the return route an air and an underwater attack succeeded.  It is still regretted that it was not possible to detect and sink more steamers in the storm.  The boat knocked off 3 steamers of about 18000 GRT.  
                    Minor malfunctions of the engines were corrected underway.  There was ice damage on the over deck and the outer tube doors.  
                    The crew performed well, especially the bridge watch with the heavy seas.  Except for minor cases all were healthy and seaworthy.  The Midshipmen continued their training and performed especially well as plotting mates.

Comments of the F.d.U. - Norwegen
 
 
on the K.T.B. of "U-255" from 10.2.43 - 15.03.43.
 
 

 

 
 
1.) To 24 February 11.05 hours:  It turned out to be the Holmes Luftwaffe Radio Beacon that worked on the same frequency as the contact keeper.  Side probably determined incorrectly.
2.) To 4 March 09.51 hours:  The propagation conditions of short wavelengths in the period from 2 to10 March 1943 in the Polar area were very bad due to electromagnetic storms. Radio communications with the boats at sea was frequently broken.  The disturbances were constantly announced by the Rechlin Radio Advisory Center and the Tromsö Radio Observation Center.  On 3 March the following report was issued:  Double interference short wave propagation for the second half of the night until noon on 4 March.  In the Polar zone failures are to be expected.
  Against these propagation disturbances a frequent change is ineffective and the boats must rely on very long wavelength reception.
3.) The success and toughness of the proven boat is recognized.
