Radio Summary of Radio Log

 
 
                                                 Comments of the Befehlshabers der Unterseeboote
                                                 on the Kriegstagebuch " U-564 " from 18.9.42 - 30.12.42.
 
        First patrol of the Kommandanten!
        Even considering it was the first patrol of the Kommandanten he operated with remarkable ineptitude and caution. The Kommandant had an abundance of attack opportunities which were not seized with the energy necessary to bring him a shooting opportunity and thus success.
        The Kommandant must still prove himself and show whether he has enough boldness and skill.
 
                                                 For the Befehlshaber der Unterseeboote
  - The Chief of the Operations Department -
