In lots and lots of patrols (probably about 100) I've seen 2 or 3 task forces. The latest (outside Freetown in June '44) was a squadron of 3 DDs...
Earlier I used to cheat and look at those lists of where the BBs etc. are located in Scapa Flow and Loch Ewe, but that got quite boring after a while. All too easy.
Btw. I encountered a large convoy recently, and among the ships was an auxilliary cruiser. It is no more...
