While Simon was impatiently expecting succour from Jamaica, and astonished at Mansvelt's really unavoidable silence, the Spaniards were preparing to smoke out the wasps' nest that lay so dangerously near their orchard. A new governor of Costa Rica threw unusual decision into their plans. Fearing they should lose the Indies piecemeal, they resolved to crush the evil ere it grew indestructible. Don Juan Perez de Guzman equipped a fleet of four vessels with fifty or sixty men each, commanded by Don Joseph Sancho Ximenes, major-general of the garrison of Porto Bello. Don Juan, in a letter to Simon, promised him a reward if he would surrender the island to his Catholic Majesty, and threatened him with punishment if he resisted. Simon, seeing the impossibility and uselessness of resistance, surrendered it after a few shots, on the same condition with which Morgan had obtained it from the enemy.

The Spaniards made much of their victory, publishing "a true relation and particular account of the victory obtained by the arms of his Catholic Majesty, against the English pirates, by the direction and valour of Don Juan Perez de Guzman, knight of the order of St. James, governor and captain-general of Terra Firma, and the province of Veraguas."

The account goes on to describe the arrival of fourteen English vessels on the coast, 1665, their arrival at Puerto de Naos, and the capture of St. Catherine's from the governor, Don Estevan del Campo, the enemy landing unperceived. Upon this the valorous Don Juan called a council of war, wherein he declared the great progress the said pirates had made in the dominions of his Catholic Majesty, and propounded, "that it was absolutely necessary to send some forces to the isle of St. Catherine, sufficient to retake it from the pirates, the honour and interest of his Majesty of Spain being very narrowly concerned herein, otherwise the pirates, by such conquests, might easily, in course of time, possess themselves of 'all the countries thereabout.'" The less vapouring, or more pacific, ingeniously proposed to leave the pirates alone till they perished for want of provisions, but Don Juan, overruling their timidity, sent stores to the militia of Porto Bello, and conveyed himself there, with no small danger of his life. At this port he found the St. Vincent, a good ship, belonging to the Negro Company, which he equipped with a crew of 270 soldiers, thirty-seven prisoners, thirty-two of the Spanish garrison, twenty-nine mulattos of Panama, twelve Indian archers, seven gunners, two lieutenants, two pilots, a surgeon, and a Franciscan chaplain. Before they set sail, Don Juan (who did not go with them) encouraged them to fight against the enemies of their country and their religion, "those inhuman pirates who had committed so many horrid cruelties upon the subjects of his Catholic Majesty," promising liberal rewards to all who behaved themselves well in the service of their king and country. At Carthagena, they received a reinforcement of one frigate, one galleon, a boat, and 127 men.

On arriving at the island, the pirates discharged three guns, refused to surrender, and declared they preferred to lose their lives. The next day three negro deserters, swimming to the admiral, told him there were only seventy-two men on the island, and two days after the day of the Assumption the Spaniards landed and commenced the affray. The St. Vincent attacked the Conception battery, the St. Peter the St. James's forts, the pirates driving off many of the enemy by loading their guns with part of the pipes of a church organ, threescore pipes at a time. The pirates lost six men before surrendering, the Spaniards one. They found in the island 800 lbs. of powder, and 250 lbs. of bullets. Two Spanish deserters, discovered amongst the prisoners, were "shot to death" the next day. The prisoners were transported to Puerto Velo, all but three, who, by order of the governor, were kept as a trophy, like chained Samsons, to work in the castle of St. Jerome at Panama, a fortress building by the governor at his own expense.

A day or two after this unavoidable surrender, a vessel arrived at St. Catherine, bringing reinforcements and provisions from the governor of Jamaica, who had repented of his rejection of Mansvelt's proposal, but had not even yet the courage to be boldly dishonest. The Spaniards, hoisting an English flag, persuaded Simon to welcome it, and betray it into their hands. There were fourteen men on board and two women, all of whom were made prisoners.

On the death of Mansvelt, Morgan became without opposition the leader of all the adventurers of Jamaica. He at once published far and wide his intention of setting out on a grand expedition, and named Cuba as a rendezvous, St. Catherine's not being far distant. Morgan had been no less anxious than Mansvelt to make this island a fortress and a storehouse. He had written to the merchants of Virginia and New England, to contract with them for ammunition and provisions; but this hope being ended by the Spanish conquest, he felt himself free to embark on a wider and more ambitious field. His plans were for a moment defeated, but his courage and ambition were not a whit humbled.

Two months spent in the southern ports of Cuba sufficed him to collect a fleet of twelve sail, with 700 fighting men, part English, part French, resolved to follow him to the death. To prevent the disunion so frequent between the two nations, Morgan had a clause inserted in the charter-party, empowering him to condemn to instant death any adventurer who killed or wounded another. A council was then called to decide on what place they should first fall. Some proposed Santiago, which had been before sacked, others a swoop on the tobacco of the Havannah, or the dye-woods of Campeachy. Many voices were strong for a night assault on the Havannah, which, they said, could be taken before the castle could be ready to defend itself. The very ransom of the clergy they might carry off, would be worth more than the pillage of a smaller town. But some Buccaneers, who had been prisoners there, said nothing could be done with less than 1500 men, and the proposal was abandoned, when they proved that they must first go to the island de los Pinos, and land in small boats at Matamana, fourteen leagues from the city.

At last some one proposed a visit to Port-au-Prince, a town of Cuba, very rich from its traffic in hides, and which, being far inland and built on a plain, could be very easily surprised. The speaker knew the city well, and was sure that it never had been sacked. Despairing of collecting forces enough to attempt the Havannah, they pursued the Spaniard's plan. Morgan at once acceded to this scheme, and, giving the captain the signal of weighing anchor, steered for Port St. Mary, the nearest harbour to Port-au-Prince. The night of their arrival in the bay a Spanish prisoner threw himself into the sea, and swimming on shore went to inform the governor of the Buccaneers' plans, having, with a scanty knowledge of English, gathered a full insight, deeper than history tells us, of Morgan's intentions.

The governor instantly sent to the neighbouring town for succour, and collected, in a few hours, a force of 800 armed freemen and slaves, occupying a pass which the Buccaneers must traverse. He cut down the trees, barricaded the approaches, and planned eight ambuscades, strengthened by cannon to play upon them on their march. He then marched out into a savannah, where he might see the Buccaneers at a long distance.
