Did the logbook of the HMS Bounty survive?
Did the logbook of the Bounty remain with the ship, and was subsequently burned along with the ship off of Pitcairn Island, or did Fletcher give the logbook to Bligh when he set him adrift at the time of the mutiny? In which case it would have ended up back in England...
Bligh (or one of his subordinates) must have made detailed notes about their time in Tahiti. I would think this would make for some fascinating reading.
