    13.08.44      
    16.00 Bordeaux Made fast U-boat Bunker 3 b.  
           
    14. - 16.08.44   Cleared the boat.  
           
    17. - 24.08.44   Shipyard overhaul.  Due to development of the situation there is only limited time for the most urgent work, therefore installation of a fixed snorkel and replacement of a few cylinder liners.  At the same time took over and equipped the boat.  
           
    25.08.44      
    12.00 Bordeaux Departed U-boat Bunker 6 for 2nd patrol (transfer to Norway).  Proceeded with "U-857" in convoy by 1 escort vessel to "Ile Verte".  
    15.06   Anchored at the north tip of "Ile Verte".  
    16.35   Put the boat on the bottom.  
    19.46   Surfaced.  
    20.59   Beginning of twilight.  
    22.06 ["Sparer" not understood - perhaps the type of tone (contunuous, wavering etc)?] Continued without escort with "U-857" via Point "446" and "Garten".  Boats themselves deploy noise buoys.  From Royan continual detections (Sparer) in Naxos range.  No approaches.

        Outbound Orders "U-534", "U-587".  
        1.)  Depart Bordeaux 26 August morning with escort to Point "446", transfer to Norway.  
        2.)  From Point 446 "Nollau" proceeds about 15 nm to the north . . . . Route Rosengarten.  "Nollau" objective BE 54.  
        3.)  Strongest surveillance by enemy air and search groups, nights focal point within the 100-meter line.  
                                                                F.d.U. West.  
    03.22   Reached Point "Garten".  Noise buoys released.  Dived depth A -50 meters.

    16.00 BF 9235    
    23.50   Went to snorkel depth.  When starting the diesel the diesel room was heavily smoked because the exhaust gas piping leaks.  Boat must surface.  Conning tower hatch cannot be opened.  Ob.Strm. goes out through the Galley hatch and opens the conning tower hatch from the outside.  
    24.00 BF 9234 Surfaced.

Concluding remarks
 
     
  The boat departed on 25.8.1944 after a 4-6 days long shipyard period after it had previously been out 15-1/2 weeks. The situation in France required the shipyard period be reduced as much as possible. Only a fixed snorkel was installed and a few cylinder liners were replaced. A snorkel cam was not installed. After the first snorkeling attempt, in which the boat immediately filled with smoke (personnel casualties) the boat was forced to surface, immediately there was locating and an aircraft attack. The attack was repelled and resulted in the shoot down. The anti-aircraft operation proved particularly effective here. The aircraft was brought down with 10 rounds of 3.7 cm and one magazine 2 cm for each weapon.
 
  Attempted to snorkel at the beginning of darkness but each time the attempt failed because the exhaust gas piping leaked heavily and initially the new packing was forced out.  From then on the Bay of Biscay was crossed by surfacing to charge with the fixed snorkel.  In the central North Atlantic Ocean at night also proceeded on the surface after each previous snorkel attempt failed.  After about 5 weeks the diesels were then repaired so that then nearly perfect snorkeling was carried out up to the convoy intake point.  The engine personnel performed especially well on this patrol.  
  The task of transferring the boat to the homeland could be carried out.  An operations area for the boat was not in question, because it was then no longer fully operational technically.

Comments of the Befehlshabers der Unterseeboote

 
 
on the K.T.B. of "U 534" (Nollau) from 28.8. - 28.10.1944.
 
     
          Boat was proceeding to Norway after a short shipyard period, makeshift repairs and installation of a fixed snorkel. Technical defects affected the patrol unfavorably. To recharge the battery the boat had to proceed mostly on the surface. By continually repeated attempts and the independent work of the engine personnel at the end of the patrol snorkel operation could be performed properly. The shooting down of an aircraft was a beautiful success.  
     
  Accredited success:  1 aircraft shot down.
