Kptlt. Otto Kretschmer in his U-99 appears 4 times on this listing of most successful convoy attacks by a single boat. Most of his sinkings were from convoy's unlike some who mostly hunted ships sailing on their own.

Henke's (U-515), Kals's (U-130), Lassen's (U-160) and Piening's (U-155) attacks in their larger and less agile type IX boats in late 1942 early 1943 are very impressive. Trojer (U-221) has seemingly impossibly high figure of 16 but that includes several landing craft carried on a larger ship.

Convoy attacks after 1942

These are number of ships sunk or total loss from each convoy.

Kurt Dobrat's (U-1232) patrol in Jan 1945 was really impressive and probably the most successful for all of 1945. He sank or destroyed 4 ships and damaged another before being damaged in battle and successfully made it back home.
