Targeting English, Dutch, and Portuguese possessions, he raided and ransomed the colonies of Cape Verde, Sint Eustatius, and Curaçao—factories, depots, and seasoning camps used in the Atlantic slave trade.
He also raided and ransomed Montserrat, Antigua, Surinam, Berbice, and Essequibo—wealthy sugar-producing colonies in the Caribbean whose economies were based on the exploitation of slave labor.
At the end of its expedition, Cassard's squadron returned to France with prizes in the form of cash, goods, and enslaved Africans worth between nine and ten million French livres.
Departing in early March 1712 from the port of Toulon with a fleet of eight ships, 3,000 seamen, and 1,200 soldiers, he embarked on an expedition during which he raided English, Dutch, and Portuguese colonies at Cape Verde and in the Caribbean.
[6][7] In 1678, the well-defended island had successfully avoided invasion by a larger fleet led by Jean II d'Estrées that foundered on the Las Aves archipelago.
In Cape Verde, Ribiera Grande was slowly replaced as capital of the Portuguese colony by Praia, due to the latter settlement's strategic position farther east and on a plateau, giving it better natural protection against pirate attacks.
As a result, there was a resurgence in the Golden Age of Piracy as "fully illegal" independent pirate captains took on unemployed sailors and focused on commerce raiding and smuggling.
As there was still need to further fortify Paramaribo, which had never successfully repelled an invasion, it was decided to build another fort closer to Meerzorg above the confluence of the Suriname and the Commewijne.
[15] The effort entailed in provisioning and financing the ransom demanded by Cassard was a heavy burden on the Sephardic Jewish community of Surinam, which owned a third of the colony's plantations in the early eighteenth century.
As such, it was a contributing factor to the century-long decline of plantations with Jewish owners, who slowly relocated the seat of their operations from Jodensavanne to Paramaribo, where they integrated more closely with the rest of the colony's European population.
