"Almost the entire crew survived and were then taken to POW camps in the United States where they were to remain for the rest of the war,"—reword or reference please. "Almost the entire crew" is vague and sounds like what would be defaulted to when a reference can't be found.
For the further reading section, I'd advise removing the Vol. 2 piece, only because further reading for the general topic would not be volume specific, but it could vary as to what you think the section should be for.
Amongst many other copyedits, I've changed the RN ship names so that there is only one 'HMS'. This because a group of warships are still 'HMS' - 'Her/His Majesty's Ships.
I'm also thinking of re-writing the table so that it matches the majority of other U-boat articles. i.e. 'Raiding career' as a title and the main headings reading thus: "Date || Ship || Nationality (flag then country) || Tonnage || Fate (Sunk or Damaged). I realize that the table would be slightly different to those at "Uboat.net", but that is how many other U-boat article tables are presented and at least the numbers of 'copy-and-paste' should be reduced.
