This island was the scene of the murder of two sailors by natives in Hoopiron Bay, July 28, 1885. The men were Captain John Friar and John Watkins, a carpenter of Lallah Rook, a schooner registered in Saint John, New Brunswick. The vessel anchored in the bay to take on fresh water. After the murders, the crew sailed away.
The murders were revenge taken for two unpaid-for deaths of natives in Friar's employ. Despite a two-day search of the island on October 16, by the crews of Governor Blackall, and HMS Diamond and HMS Raven, the murderers were not found, although the skulls of Friar and the carpenter were recovered and given a burial at sea. Later Diamond returned and burned all the villages nearby.
