Tromelin Island (/
The island is named for the chevalier Bernard Boudin de Tromelin, the captain of the French warship La Dauphine. He arrived at the island on 29 November 1776, and rescued eight stranded enslaved Malagasy people who had been on the island for 15 years.
Tromelin is about 1,700 metres (1.1 mi) long and 700 metres (0.43 mi) wide, with an area of 80 ha (200 acres), covered in scrub dominated by octopus bush and surrounded by coral reefs. There are no harbours or anchorages, so that access by sea is quite difficult. A 1,200-metre (3,900 ft) airstrip provides a link with the outside world.
Fauna and Flora
Flora is poorly developed due to weather conditions and lack of fresh water. With the exception of two or three months in summer, this flat island is swept day and night by heavy winds that are sustained in winter. In summer, it can suffer the onslaught of cyclones and tropical storms.
There is only grass and brush (low shrubs) present on the island. Veloutaries (Heliotropium foertherianum) and purslane (Portulaca oleracea), with growth shaped by a dominant east winds are present everywhere on the island.
The fauna consists mainly of hermit crabs (Paguroidea), seabirds and sea turtles for which the island is an important nesting place. The green turtle (Chelonia mydas), also known as the freshwater turtle, is mainly encountered and, to a lesser extent, the tortoiseshell turtle, better known as the caret.
The waters are rich with fish. The French Coral Reef Initiative (IFRECOR) has identified 26 species of corals. Allochthonous species were introduced on the island during the various shipwrecks: rats, mice and rabbits. The latter were decimated in 1986 by cyclone Erinesta.
Important Bird Area
The island has been identified as an Important Bird Area (IBA) by BirdLife International because of its significance as a seabird breeding site. Both masked (with up to 250 pairs) and red-footed boobies (up to 180 pairs) nesting there. Sulidae populations have seriously declined in the western Indian Ocean with those on Tromelin among the healthiest remaining.
The island's masked boobies are of the western Indian Ocean subspecies (Sula dactylatra melanops), of which Tromelin is a stronghold. The red-footed boobies constitute the only polymorphic population in the region, indicating its biogeographical isolation. Both great and lesser frigatebirds used to nest on the island. The breeding populations of both birds have since been extirpated, although they continue to use the island for roosting.
There are no resident landbirds.
Wreck of the ship L'Utile
In 1761 the French ship L'Utile (The Useful), a frigate of the French East India Company, chartered by Jean-Joseph de Laborde and commanded by Captain Jean de La Fargue, transporting slaves from Madagascar to Mauritius in contravention of Mauritian law, ran onto the reefs of the island. The ship had departed Bayonne in France with 142 men. After a stopover on the Isle de France (present-day Mauritius), the ship embarked 160 Malagasy men, women and children at Foulpointe, on the east coast of Madagascar, to bring them into slavery on Mauritius, despite the prohibition of trafficking decreed by the governor. A navigation error, due to the use of two conflicting charts, caused the vessel to wreck on the reefs of Tromelin Island (then known as the Isle of Sand). The ship was a frigate, not a slave ship, and thus was not equipped with the shackles and chains usually found on slave ships.
After the wreck, the crew and about 60 Malagasy people managed to reach the island, but the rest of the slaves, locked in the hold, drowned. The crew retrieved various equipment, food and wood from the wreckage. They dug a well, providing drinking water, and fed on salvaged food, turtles and seabirds.
Captain Jean de Lafargue, having lost his mind as a result of the wreck, was replaced by his first lieutenant, second-in-command, Barthelemy Castellan du Vernet who lost his brother Leon in the shipwreck. Castellan built two camps, one for the crew and one for the slaves, a forge and an oven, and, with the materials recovered from the wreckage, began construction of a boat. On 27 September 1761, a contingent of 122 French sailors (crew and officers) left Tromelin aboard the Providence. They left the surviving slaves—60 Malagasy men and women—on the desert island, promising to return and rescue them. The sailors reached Madagascar in just over four days and, after a stopover in Foulpointe, where men died of tropical diseases, were transferred to Bourbon Island (now Réunion Island), and then to the Isle de France (now Mauritius). When the crew of the ship reached Mauritius, they requested that colonial authorities send a ship to rescue the Malagasy slaves on the island. However, they met with a categorical refusal from the governor, with the justification that France was fighting the Seven Years' War and thus no ship could be spared, the island of Mauritius being itself under threat of attack from British India.
Castellan left the Isle de France to return to France in 1762 and never gave up hope to one day return to the Isle of Sand to save the Malagasy people. The news of the castaway slaves got published and stirred the Parisian intellectual milieu; later, the episode was all but forgotten with the end of the Seven Years' War and the bankruptcy of the East India Company.
In 1773, a ship passing close to Tromelin Island located the slaves and reported them to the authorities of Isle de France. A boat was sent, but this first rescue failed, as the ship couldn’t approach the island. A year later, a second ship, La Sauterelle, also failed to reach the island. During this second failed rescue, a sailor managed to swim to the island, but he had to be abandoned by the ship due to bad weather. This sailor remained on Tromelin Island and, some time later, probably around 1775, built a raft on which he embarked with three men and three women, but which disappeared at sea.
It was not until 29 November 1776, 15 years after the sinking, that the Chevalier de Tromelin, commander of the corvette La Dauphine, reached Tromelin Island and rescued the survivors—seven women and an eight-month-old child. Upon arriving there, the Chevalier de Tromelin 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 does 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 the 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 the Isle of France. The Chevalier de Tromelin was the first to precisely describe the island that now bears his name.
The Marquis de Condorcet, advocating the abolition of slavery in his book Reflections on the Slavery of Negroes published in 1781, recounted the tragedy of the castaways of Tromelin to illustrate the inhumanity of the slave trade.
Expedition "Forgotten slaves"
An archeological expedition entitled "Forgotten Slaves", led by Max Guérout, a former French naval officer and director of operations of the Naval Archeology Research Group, and Thomas Romon, archaeologist at INRAP (National Institute for Preventive Archaeological Research), took place from October to November 2006, under the patronage of UNESCO and the French Committee for the History and Remembrance of Slavery (CPMHE). The results of the research were made public on January 17, 2007. The ten members of the expedition probed the wreck of L'Utile, and searched the island for traces of shipwreck, in order to better understand the living conditions of the Malagasy people during these fifteen years. According to Max Guérout, head of the mission, "In three days, a well 5 meters deep was dug. This represented a considerable effort. We found many bones of birds, turtles, and fish." One does not have the impression that these people were crushed by their condition. They tried to survive with order and method."
An anonymous logbook, attributed to a writer of the crew, was found. Basements made of beach sandstone and coral were also found (the survivors thus transgressed a Malagasy custom according to which stone constructions were reserved for tombs). There were also six copper bowls and a pebble used to sharpen knives. The fire was maintained for fifteen years, thanks to the wood from the wreck, the island being devoid of trees.
A second expedition, organized in November 2008, did not reveal the burials observed in 1851 by an English naval officer. However, the remains of two bodies displaced during the digging of the foundations of a building of the weather station have been uncovered. Three buildings built with coral blocks have been discovered, including the kitchen, which was still equipped with kitchen utensils, and in particular copper containers that had been repaired several times, testifying to the slaves' determination to survive.
A third archaeological mission took place in November 2010. It allowed the discovery of three new buildings and many objects, including two lighters and flints, which elucidated the technique used by the castaways to rekindle the fire.
The fourth expedition, took place in September / October 2013. It lasted for 45 days, and enabled to identify many tools, shelters and to understand the layout of the site.
In 2016, an exhibition presenting the results of the various excavation campaigns, entitled "Tromelin, the island of forgotten slaves", was presented jointly in metropolitan France and in the DROM: at the Stella Matutina museum in Saint-Leu (La Réunion), the castle of the Dukes of Brittany in Nantes, the House of Agglomeration of Lorient, the Aquitaine Museum in Bordeaux, the departmental museum of archeology and prehistory of Martinique in Fort-de-France, and finally to the Basque Museum of the History of Bayonne from June to November 2017.
The French claim to sovereignty dates from 29 November 1776, the date that the ship La Dauphine arrived.
The Mauritian claim to sovereignty is based on the fact that the island was not ceded to France by the treaty of Paris in 1814.
It is a matter of dispute whether the building agreement transferred sovereignty of Tromelin from one to the other, and Mauritius claims the island as part of its territory, on the grounds that sovereignty was not transferred to France in 1814, and the island was thus part of the colony of Mauritius at the time of independence. Indeed, as early as 1959, even before independence, Mauritius informed the World Meteorological Organization that it considered Tromelin to be part of its territory. France and Mauritius reached a co-management treaty in 2010.
Tromelin has an Exclusive Economic Zone (EEZ) of 280,000 square kilometres (108,109 square miles), contiguous with that of Réunion. The island's weather station, which warns of cyclones, is still operated by France and is staffed by meteorologists from Réunion.
