The Cassard expedition was a sea voyage by French Navy captain Jacques Cassard in 1712, during the War of the Spanish Succession. 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.
