John Mills was the gunner's mate aboard HMS Bounty, a ship that, after two novels, five movies, and not to mention the actual historical account, needs little if any introduction. According to the ship's log, Capt. Bligh's personal journal, and records of the British Navy, Mills was one of the older, more-experienced crew aboard Bounty, having served on Mediator under Admiral Collinwood (himself a partner with Lord Nelson in many campaigns). Mills apparently lacked a sweet disposition, but as the record shows, he'd spent a lifetime at sea under the command of great mariners. It's safe to say he knew what he was talking about.
