In 1841, the "Trouvadore", an illegal Spanish slave ship, was wrecked off the coast of East Caicos. All of the 20 man crew and 192 captive Africans survived the sinking. Officials freed the Africans and arranged for 168 persons to be apprenticed to island proprietors on Grand Turk Island for one year. They increased the small population of the colony by seven per cent. The remaining 24 were resettled in Nassau, Bahamas. The Spanish crew were also taken there, to be turned over to the custody of the Cuban consul and taken to Cuba for prosecution. An 1878 letter documents the "Trouvadore Africans" and their descendants as constituting an essential part of the "labouring population" on the islands. In 2004, marine archaeologists affiliated with the Turks and Caicos National Museum discovered a wreck, called the "Black Rock Ship", that subsequent research has suggested may be that of the "Trouvadore". In November 2008, a cooperative marine archaeology expedition, funded by the United States NOAA, confirmed that the wreck has artefacts whose style and date of manufacture link them to the "Trouvadore".
