Of course - one has to accept that a Russian might have had a good reason for wanting the UK or its allies to think that they were somewhere near the TEZ when in fact they weren’t...feigned global reach etc. Equally a remark made in a foreign language might have been meant in a different way to the one taken - for example a decrease in submarine op tempo in the North Atlantic might have freed up NATO (in this case UK) assets to go south.
In the Falklands Edition of Flight Deck the 820 NAS entry seems to suggest they attacked a whale ‘successfully’.
Sadly any events pieced together from memories will be inaccurate. Lord knows we’ve all spent enough time in peacetime de-briefs trying to make sense of what we thought we saw!
