This listing is as accurate as the data in our database allows, mistakes or omissions should be very few and far between. Changes in the database (ships moved from one U-boat to another etc.) are reflected immediately.

Please note: These tonnage figures (and sometimes the number of ships sunk) is still being debated among historians. This is one of several different possible figures but still very close whatever the "real truth is". This is often due to convoy battles at night when an attacking wolfpack fired torpedoes into the convoy and two commanders claimed the same ship, although post-war research has eliminated most of those doubtful victims there are still some in question.
