 While aboard the corvette "Bayonnaise", Tromelin came across Sydney Island and Phoenix Island, probably in 1828, although some sources state 1823 and 1826.Placing the island at 3°42'S, 189°17'E, Tromelin claimed it was already reported on Norie's map.A "Phenix", plus unnamed islands at similar coordinates feature in Jeremiah N. Reynolds's 1828 report to the American Navy, but the source of the name (and discoverer) remains contentious.
