I've seen two convoys off Scotland in 1940 with Nelson or Revenge BBs in their midst.
Hit the Nelson with 3 torps but got DC'd to destruction before it sank (I was young and inexperienced

). Hit the Revenge with 4, yes 4 torps and sneaked away deep. It sank.
Otherwise sank a Fiji in Loch Ewe.
These were all GWX.
