                         Commentary of the Befehlshaber der Unterseeboote

 
 
                         On the K.T.B. of "U-615" (Kapitzky) from 10.1.43 - 20.4.43.
 
 

 

 
  On the crash dive on 22 February at 15.13 hours:  Do not dive when the aircraft is already too close.   Repel the first approach on the surface.  
  On the convoy operation from 16 - 19 March:  The offered attack opportunity was not utilized.  Never put off an attack without a valid reason.  Also, the U-boat is very difficult to see in moonshine.  
  The Kommandant must make use of previous experience, a good measure of self-confidence and optimism is justified and also necessary.  
     
  Accredited success:  
  1 munitions steamer           12000 GRT sunk
