2 U-boats abeam to starboard come towards us at highest speed.  Therefore they must have been at the convoy.  As a precaution came to the same course and to GF.  After 1/2 hour destroyer masts come in sight behind the boats.  Went to AK.  The two other boats are quicker than me.  The destroyer comes out further and opens cannon fire at 7000 meters.  After 20 minutes the fire is so accurate that I must dive.  Afterwards for 7 hours well-placed depth charges, locating and listening pursuit.

                         Comments of the Befehlshabers der Unterseeboote  
                         on the K.T.B. of "U-533" (Hennig) from 25.11.42 - 24.5.43  
     
  First patrol of the Kommandanten with a new boat.  
     
  The anti-aircraft defense on 25 April was good and soon more effective ammunition will also lead to safe firing. The operation on the "Witzendorff-convoy" pitted the boat against strong air and sea defense which the Kommandant bravely outmaneuvered without reaching attack position. 2 bad operating errors with depth charges on 28 April and while preparing the torpedo tubes on 30 April which could easily have been disastrous for the boat ruined a promising attack opportunity for the Kommandant.  
     
  The operation on the "Pückler-convoy" and "Hasenschar-convoy" lead to no success - but instead a very strong contact (ramming) with a destroyer, which the boat escaped by a hairsbreadth.  
     
  During operation on the 'Luis-convoy" the boat encountered only defenses.  
     
  The first patrol was very rich in events of all kinds and was a harsh baptism of fire. Kommandant, boat and crew have welded together well.
