During the War of the Spanish Succession [1701-1714] which was fought between the European powers, including a divided Spain, over who had the right to succeed Charles II as the King of Spain. The Portuguese had sided with the English during the War of Spanish Succession and in retaliation the French sent a Navy fleet to Cape Verde to attack and sack the islands.[1]
During this conflict, a sea voyage was taken by French Navy Captain Jacques Cassard in 1712 this would be known as the Cassard Expedition. Departing from the port of Toulon [France] with a fleet of eight ships, 3,000 seamen and 1,200 soldiers. This is the fleet that on the 4th of May of 1712 he disembarked his soldiers at Praia Negra, Vila da Praia, Santiago [located in the bay of the city of Praia]. The French arrested the Captain-General and spread throughout the island of Santiago pillaging and burning the homes and the farms of the citizens of the villages and the city of Ribeira Grande [Cidade Velha][2].
The French soldiers arrested women and children and used them as hostages to keep the male residents from retaliating, while they continued burning and pillaging the city of Ribeira Grande and stole everything from slaves, gold, silver and also church chalices and even church bells. After sacking and pillaging Praia and Ribeira Grande, the French turned their attention to Santo Antão [1712][3]; with these successful attacks the French briefly wrangled control of Cape Verde from the Portuguese.
This attack by the French Corsair Jacques Cassard on Ribeira Grande led to the decline of the city and prompted the residents to move the capital to the Praia Plateau, which was easier to defend.
In 1798, the French return and attack the island of Brava in their unsuccessful effort to dislodge the Portuguese influence there and on the coast.[4]
