Archibald Armstrong was 2nd mate on the Fisburn (promoted to chief mate at Rio de Janeiro), which landed in Sydney in January 1788 as part of the First Fleet.
It is believed he was the same Archibald Armstrong who was master of the Atlantic transport in 1791 as part of the Third Fleet, and then first mate of the Kitty in 1793-94 and master of the Supply in 1797. He died at sea while trying to rescue the crew of the Sydney Cove which had been wrecked on an island in the Furneaux group off the north east corner of Van Diemen's Land early in July 1797. He completed the rescue of the survivors but was lost in a violent storm during the return to Sydney.
