Part of the Spanish fleet in Venezuela had been warned because a Dutch cabin boy had lost his way on Blanquilla island and was captured, betraying the plan, but the other half from Mexico continued its voyage, unaware of the threat. Sixteen Spanish ships were intercepted; one galleon was taken after a surprise encounter during the night, nine smaller merchants were talked into a surrender; two small ships were taken at sea fleeing, four fleeing galleons were trapped on the Cuban coast in the Bay of Matanzas. After some musket volleys from Dutch sloops their crews surrendered also and the Dutch captured 11,509,524 guilders of booty in gold, silver, and other expensive trade goods, as indigo and cochineal, without any bloodshed. The Dutch did not take prisoners: they gave the Spanish crews ample supplies for a march to Havana. The treasure was the company's greatest victory in the Caribbean.
