Commentary of the Befehlshabers der Unterseeboote

 
 
on the War Diary of "U-156" from 07.07 - 16.11.1942.
 
 

 

 
 
                A well executed patrol.
                The Kommandant was in a difficult position during the rescue operation of the "LACONIA-shipwrecked".  It was wrong to believe in an "implied armistice".  It almost led to the loss of the boat.  Because leadership refrained from transmitting the status and refusal of the neutralization, he acted in his best belief.   The incident is renewed proof of the harmful effect of humanitarian feelings with such an enemy.
                The security of one's own boat must always remain fully protected.
