In 1655, when an English fleet under Penn and Venables came to the Indies to attack the Spaniards, a body of English buccaneers who had settled at Barbadoes came in their ships to join the colours. In all, 5000 of them mustered, but the service they performed was of poor quality. The combined force attacked St Domingo, and suffered a severe repulse. They then sailed for Jamaica, which they took without much difficulty. The buccaneers found Jamaica a place peculiarly suited to them: it swarmed with wild cattle; it had a good harbour; it lay conveniently for raids upon the Main. They began to settle there, at Port Royal, with the troops left there by Cromwell's orders. They planted tobacco and sugar, followed the boucan, and lived as they had lived in the past at Hispaniola. Whenever England was at war with Spain the Governor of the island gave them commissions to go privateering against the Spanish. A percentage of the spoil was always paid to the Governor, while the constant raiding on the Main prevented the Spaniards from attacking the new colony in force. The buccaneers were thus of great use to the Colonial Government. They brought in money to the Treasury and kept the Spanish troops engaged. The governors of the French islands acted in precisely the same way. They gave the French buccaneers every encouragement. When France was at peace with Spain they sent to Portugal ("which country was then at war with Spain") for Portuguese commissions, with which the buccaneer captains could go cruising. The English buccaneers often visited the French islands in order to obtain similar commissions. When England was at war with Spain the French came to Port Royal for commissions from the English Governor. It was not a very moral state of affairs; but the Colonial governors argued that the buccaneers were useful, that they brought in money, and that they could be disowned at any time should Spain make peace with all the interloping countries. The buccaneers now began "to make themselves redoubtable to the Spaniards, and to spread riches and abundance in our Colonies." They raided Nueva Segovia, took a number of Spanish ships, and sacked Maracaibo and western Gibraltar. Their captains on these raids were Frenchmen and Portuguese. The spoils they took were enormous, for they tortured every prisoner they captured until he revealed to them where he had hidden his gold. They treated the Spaniards with every conceivable barbarity, nor were the Spaniards more merciful when the chance offered.
