At the beginning of the 17th century, pirates infested the Caribbean waters, harassing the major European powers, but they were eventually driven from the region. Some pirates took refuge in Madagascar, where they attempted to capture the lucrative cargo carried by vessels on the shipping route of the European East India Companies. At the end of the 18th century, in order to weaken British influence in the Indian Ocean, France hired privateers to attack commercial ships of the British East India Company. This was an alternative to open warfare, and heralded the privateers' era. Denis Piat recounts the history of the pirates and privateers in the Indian Ocean, especially in Mauritius, from the pirates' arrival in the region to the wrecked ships still to be found today in deep water, and provides portraits of the most famous privateers among them.
