It was not until 29 November 1776, 15 years after the sinking, that Ensign Tromelin-Lanuguy, captain of the corvette "Dauphine", reached Tromelin Island and rescued the survivors – seven women and an eight-month-old child. Upon arriving there, Tromelin-Lanuguy discovered that the survivors were dressed in plaited feather clothes and that they had managed, during all these years, to keep a fire lit (the island did not have a single tree). The Malagasy people, who had been left on the bleak little island, built a shed with coral stones, for most of the wood had been used in the construction of the raft for the crew. They also built a lookout on the highest point of the island in order not to miss the ship that would, they hoped, come to their rescue. They were all from the Central Highlands of Madagascar, and had no knowledge of how to produce food in the coastal environment. Most had died within the first few months on the island. The survivors remained with Jacques Maillart, governor of Mauritius ("Isle de France"), who declared them free and offered to bring them back to Madagascar, which they refused. Maillart decided to baptize the child Jacques Moyse (Moses), on the day of his arrival in Port-Louis on 15 December 1776, and to rename his mother Eve (her Malagasy name was Semiavou) and to do the same with the child's grandmother, whom he called Dauphine after the name of the corvette that rescued them. The trio was welcomed in the house of the intendant of Mauritius ("Isle de France"). Tromelin was the first to precisely describe the island that now bears his name.
