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.

	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
		For the Befehlshaber der Unterseeboote
