Note:  The positions in the table above and in the Google Earth patrol summary are derived from the KTB and in many cases do not match those set forth in authoritative references such as Jürgen Rohwer, Axis Submarine Successes of World War Two or the Uboat.net website.  The goal here is to present the picture relative to the U-boat and not the absolute position that the ship was attacked or sank.

                    on the K.T.B. of "U-466" (Thäter) from 29.6. - 16.8.1943.

 
     
 

        The Kommandant had to abort the patrol because of numerous casualties of the bridge crew by strafing fire after the aircraft attack on 24 July.

 
 
         The behavior with respect to the numerous aircraft attacks was good.  Otherwise no success possibilities presented themselves to the Kommandant.
