It was something of a hazard, for the Spanish garrison was formed of all the desperate criminals the colonial police could catch. These men made excellent soldiers, for after a battle they were given the plunder of the men they had killed. Then Panama, with its great garrison, was perilously near at hand, being barely sixty miles away, or two days' journey. Lastly, the town was strongly fortified, with castles guarding it at all points. The garrison was comparatively small, mustering about three companies of foot. To these, however, the buccaneers had to add 300 townsfolk capable of bearing arms. Following John Exquemeling's plan, we add a brief description of this famous town, to help the reader to form a mental picture of it.

Porto Bello stands on the south-eastern side of a fine bay, "in the province of Costa Rica." At the time when Morgan captured it (in June 1668) it was one of the strongest cities in the possession of the King of Spain. It was neglected until 1584, when a royal mandate caused the traders of Nombre de Dios to migrate thither. It then became the port of the galleons,[16] where the treasures of the south were shipped for Spain. The city which Morgan sacked was built upon a strip of level ground planted with fruit-trees, at a little distance from the sea, but within a few yards of the bay. The westward half of the town was very stately, being graced with fine stone churches and the residence of the lieutenant-general. Most of the merchants' dwellings (and of these there may have been 100) were built of cedar wood. Some were of stone, a thing unusual in the Indies, and some were partly stone, with wooden upper storeys. There was a fine stone convent peopled by Sisters of Mercy, and a dirty, ruinous old hospital for "the sick men belonging to the ships of war." On the shore there was a quay, backed by a long stone custom-house. The main street ran along the shore behind this custom-house, with cross-streets leading to the two great squares. The eastward half of the city, through which the road to Panama ran, was called Guinea; for there the slaves and negroes used to live, in huts and cottages of sugar-cane and palm leaves. There, too, was the slave mart, to which the cargoes of the Guinea ships were brought. A little river of clear water divided the two halves of the town. Another little river, bridged in two places, ran between the town and Castle Gloria. The place was strongly fortified. Ships entering the bay had to pass close to the "Iron Castle," built upon the western point. Directly they stood away towards the town they were exposed to the guns of Castle Gloria and Fort Jeronimo—the latter a strong castle built upon a sandbank off the Guinea town. The constant population was not large, though probably 300 white men lived there all the year round, in addition to the Spanish garrison. The native quarter was generally inhabited by several hundred negroes and mulattoes. When the galleons arrived there, and for some weeks before, the town was populous with merchants, who came across from Panama to buy and sell. Tents were pitched in the Grand Plaza, in front of the Governor's house, for the protection of perishable goods, like Jesuits'-bark. Gold and silver bars became as common to the sight as pebbles. Droves of mules came daily in from Panama, and ships arrived daily from all the seaports in the Indies. As soon as the galleons sailed for Spain, the city emptied as rapidly as it had filled. It was too unhealthy a place for white folk, who continued there "no longer than was needful to acquire a fortune."

Indeed, Porto Bello was one of the most pestilential cities ever built, "by reason of the unhealthiness of the Air, occasioned by certain Vapours that exhale from the Mountains." It was excessively hot, for it lay (as it still lies) in a well, surrounded by hills, "without any intervals to admit the refreshing gales." It was less marshy than Nombre de Dios, but "the sea, when it ebbs, leaves a vast quantity of black, stinking mud, from whence there exhales an intolerable noisome vapour." At every fair-time "a kind of pestilential fever" raged, so that at least 400 folk were buried there annually during the five or six weeks of the market. The complaint may have been yellow fever; (perhaps the cholera), perhaps pernicious fever, aggravated by the dirty habits of the thousands then packed within the town. The mortality was especially heavy among the sailors who worked aboard the galleons, hoisting in or out the bales of merchandise. These mariners drank brandy very freely "to recruit their spirits," and in other ways exposed themselves to the infection. The drinking water of the place was "too fine and active for the stomachs of the inhabitants," who died of dysentery if they presumed to drink of it. The town smoked in a continual steam of heat, unrelieved even by the torrents of rain which fall there every day. The woods are infested with poisonous snakes, and abound in a sort of large toad or frog which crawls into the city after rains. The tigers "often make incursions into the street," as at Nombre de Dios, to carry off children and domestic animals. There was good fishing in the bay, and the land was fertile "beyond wonder," so that the cost of living there, in the tiempo muerto, was very small. There is a hill behind the town called the Capiro, about which the streamers of the clouds wreathe whenever rain is coming. The town was taken by Sir Francis Drake in 1595, by Captain Parker in 1601, by Morgan in 1668, by Coxon in 1679, and by Admiral Vernon in 1740.

Having told his plans, the admiral bade his men make ready. During the afternoon he held towards the west of Porto Bello, at some distance from the land. The coast up to the Chagres River, and for some miles beyond, is low, so that there was not much risk of the ships being sighted from the shore. As it grew darker, he edged into the land, arriving "in the dusk of the evening" at a place called Puerto de Naos, or Port of Ships, a bay midway between Porto Bello and the Chagres, and about ten leagues from either place.

They sailed westward up the coast for a little distance to a place called Puerto Pontin, where they anchored. Here the pirates got their boats out, and took to the oars, "leaving in the ships only a few men to keep them, and conduct them the next day to the port." By the light of lamps and battle lanterns the boats rowed on through the darkness, till at midnight they had came to a station called Estera longa Lemos, a river-mouth a few miles from Porto Bello, "where they all went on shore." After priming their muskets, they set forth towards the city, under the guidance of an English buccaneer, who had been a prisoner at Porto Bello but a little while before. When they were within a mile or two of the town, they sent this Englishmen with three or four companions to take a solitary sentry posted at the city outskirts. If they could not take him, they were to kill him, but without giving the alarm to the inhabitants. By creeping quietly behind him, the party took the sentry, "with such cunning that he had no time to give warning with his musket, or make any other noise." A knife point pressing on his spine, and a gag of wood across his tongue, warned him to attempt no outcry. Some rope-yarn was passed about his wrists, and in this condition he was dragged to Captain Morgan. As soon as he was in the admiral's presence, he was questioned as to the number of soldiers then in the forts, "with many other circumstances." It must have been a most uncomfortable trial, for "after every question, they made him a thousand menaces to kill him, in case he declared not the truth." When they had examined him to their satisfaction, they recommenced their march, "carrying always the said sentry bound before them." Another mile brought them to an outlying fortress, which was built apparently between Porto Bello and the sea, to protect the coast road and a few outlying plantations. It was not yet light, so the pirates crept about the fort unseen, "so that no person could get either in or out." When they had taken up their ground, Morgan bade the captured sentry hail the garrison, charging them to surrender on pain of being cut to pieces. The garrison at once ran to their weapons, and opened a fierce fire on the unseen enemy, thus giving warning to the city that the pirates were attacking. Before they could reload, the buccaneers, "the noble Sparks of Venus," stormed in among them, taking them in their confusion, hardly knowing what was toward. Morgan was furious that the Spaniards had not surrendered at discretion on his challenge. The pirates were flushed with the excitement of the charge. Someone proposed that they "should be as good as their words, in putting the Spaniards to the sword, thereby to strike a terror into the rest of the city." They hustled the Spanish soldiers "into one room," officers and men together. The cellars of the fort were filled with powder barrels. Some ruffian took a handful of the powder, and spilled a train along the ground, telling his comrades to stand clear. His mates ran from the building applauding his device. In another moment the pirate blew upon his musket match to make the end red, and fired the train he had laid, "and blew up the whole castle into the air, with all the Spaniards that were within." "Much the better way of the two," says one of the chroniclers, who saw the explosion.

"This being done," says the calm historian, "they pursued the course of their victory" into the town. By this time, the streets were thronged with shrieking townsfolk. Men ran hither and thither with their poor belongings. Many flung their gold and jewels into wells and cisterns, or stamped them underground, "to excuse their being totally robbed." The bells were set clanging in the belfries; while, to increase the confusion, the Governor rode into the streets, calling on the citizens to rally and stand firm. As the dreadful panic did not cease, he rode out of the mob to one of the castles (Castle Gloria), where the troops were under arms. It was now nearly daybreak, or light enough for them to see their enemy. As the pirates came in sight among the fruit-trees, the Governor trained his heavy guns upon them, and opened a smart fire. Some lesser castles, or the outlying works of Castle Gloria, which formed the outer defences of the town, followed his example; nor could the pirates silence them. One party of buccaneers crept round the fortifications to the town, where they attacked the monastery and the convent, breaking into both with little trouble, and capturing a number of monks and nuns. With these they retired to the pirates' lines.

For several hours, the pirates got no farther, though the fire did not slacken on either side. The pirates lay among the scrub, hidden in the bushes, in little knots of two and three. They watched the castle embrasures after each discharge of cannon, for the Spaniards could not reload without exposing themselves as they sponged or rammed. Directly a Spaniard appeared, he was picked off from the bushes with such precision that they lost "one or two men every time they charged each gun anew." The losses on the English side were fully as severe; for, sheltered though they were, the buccaneers lost heavily. The lying still under a hot sun was galling to the pirates' temper. They made several attempts to storm, but failed in each attempt owing to the extreme gallantry of the defence. Towards noon they made a furious attack, carrying fireballs, or cans filled with powder and resin, in their hands "designing, if possible, to burn the doors of the castle." As they came beneath the walls, the Spaniards rolled down stones upon them, with "earthen pots full of powder" and iron shells filled full of chain-shot, "which forced them to desist from that attempt." Morgan's party was driven back with heavy loss. It seemed to Morgan at this crisis that the victory was with the Spanish. He wavered for some minutes, uncertain whether to call off his men. "Many faint and calm meditations came into his mind" seeing so many of his best hands dead and the Spanish fire still so furious. As he debated "he was suddenly animated to continue the assault, by seeing the English colours put forth at one of the lesser castles, then entered by his men." A few minutes later the conquerors came swaggering up to join him, "proclaiming victory with loud shouts of joy."

Leaving his musketeers to fire at the Spanish gunners, Morgan turned aside to reconnoitre. Making the capture of the lesser fort his excuse, he sent a trumpet, with a white flag, to summon the main castle, where the Governor had flown the Spanish standard. While the herald was gone upon his errand, Morgan set some buccaneers to make a dozen scaling ladders, "so broad that three or four men at once might ascend by them." By the time they were finished, the trumpeter returned, bearing the Governor's answer that "he would never surrender himself alive." When the message had been given, Captain Morgan formed his soldiers into companies, and bade the monks and nuns whom he had taken, to place the ladders against the walls of the chief castle. He thought that the Spanish Governor would hardly shoot down these religious persons, even though they bore the ladders for the scaling parties. In this he was very much mistaken. The Governor was there to hold the castle for his Catholic Majesty, and, like "a brave and courageous soldier," he "refused not to use his utmost endeavours to destroy whoever came near the walls." As the wretched monks and nuns came tottering forward with the ladders, they begged of him, "by all the Saints of Heaven," to haul his colours down, to the saving of their lives. Behind them were the pirates, pricking them forward with their pikes and knives. In front of them were the cannon of their friends, so near that they could see the matches burning in the hands of the gunners. "They ceased not to cry to him," says the narrative; but they could not "prevail with the obstinacy and fierceness that had possessed the Governor's mind"—"the Governor valuing his honour before the lives of the Mass-mumblers." As they drew near to the walls, they quickened their steps, hoping, no doubt, to get below the cannon muzzles out of range. When they were but a few yards from the walls, the cannon fired at them, while the soldiers pelted them with a fiery hail of hand-grenades. "Many of the religious men and nuns were killed before they could fix the ladders"; in fact, the poor folk were butchered there in heaps, before the ladders caught against the parapet. Directly the ladders held, the pirates stormed up with a shout, in great swarms, like a ship's crew going aloft to make the sails fast. They had "fireballs in their hands and earthen pots full of powder," which "they kindled and cast in among the Spaniards" from the summits of the walls. In the midst of the smoke and flame which filled the fort the Spanish Governor stood fighting gallantly. His wife and child were present in that house of death, among the blood and smell, trying to urge him to surrender. The men were running from their guns, and the hand-grenades were bursting all about him, but this Spanish Governor refused to leave his post. The buccaneers who came about him called upon him to surrender, but he answered that he would rather die like a brave soldier than be hanged as a coward for deserting his command, "so that they were enforc'd to kill him, nothwithstanding the cries of his Wife and Daughter."
