How do we know what happened to Bligh and his crew after they were set adrift?

After being set adrift in 1789 following the mutiny on the HMS Bounty, Captain William Bligh and his loyal crew navigated over 3,600 nautical miles in a small open boat to reach safety. They arrived at Timor, an Indonesian island, after a harrowing journey lasting nearly seven weeks. Bligh documented their experiences in a detailed log, which provides a firsthand account of their survival and the challenges they faced. Subsequent investigations and historical records help corroborate their journey and the fate of the mutineers.
