                         Commentary of the Befehlshaber der Unterseeboote

 
 
                         On the Kriegstagebuch of "U-615" from 25.11.42 - 9.1.43.
 
 

 

 
 
                 Not a very satisfactory war patrol.  Was in contact with 3 different convoys without realizing success.  Reasons are the numerous engine breakdowns of the boat during the convoy operations and furthermore, overestimation of the screen, premature diving before destroyers and remaining submerged too long.  On the evening of 28 December for example, the boat was positioned at the front of the convoy.  The Kommandant remained dived for over 4 hours after he was forced to submerge by an escort vessel and was immediately depth charged without essential failures, while continual torpedo detonations betrayed the successful attacks of the other boats.
 
 
                 The Kommandant must not be distracted too long from his main objective, namely to get at the ships, by diving too long and being forced off.
