The buccaneers, according to their usual stratagem, instead of bringing their wooden walls up to be battered by the guns of the fort, cast anchor about a mile from the castle, and landing, cut a path with hatchet and sabre through the tangled forest, to attack the works upon their weakest side. Early in the morning the landing was effected. By the middle of the afternoon they had reached a hill, from whose summit they could throw their shot into the fort, could they but have drawn their cannon to that spot. But the marshy ground would not admit of this. The garrison had brought their guns to bear upon the eminence, and opened a fire before which many of the pirates fell. Bradley was greatly disheartened. The fort proved to be of very unexpected strength. It was surrounded by two high parallel walls of timber, filled in with earth. Well-constructed bastions were at each corner. The works were enclosed by a ditch, thirty feet deep. There was but one entrance, and that was by a drawbridge across this ditch. The north side of the castle was washed by the broad and rapid river. On the south there was a precipitous inaccessible crag. Strong batteries guarded the approaches to both the other sides. Even the most desperate of the pirates recoiled from the idea of attempting to carry works so formidable by assault. But Bradley could not endure the thought of the scorn and rage he would encounter from Morgan should he retreat without making the attempt. After much perplexity and disputing it was resolved to hazard the assault. They hoped with hatchet and sabre to cut down the timber, and then to clamber over the crumbling earth. The interior of the works was all of wood. There were barracks and huts, which, beneath the blaze of a tropical sun, had become dry as powder. Cautiously the buccaneers descended the hill, throwing themselves upon their faces as the explosions of the massive guns showered the balls around them. Their sharpshooters threw bullets through the loops of the walls, and through the embrasures, to strike down the artillery-men at the guns. This skirmishing was continued until night, but nothing was accomplished. Many of the pirates were killed, and Bradley himself had one of his legs broken by a cannon-ball. The reckless men charged up to the very walls, threw over fire-balls, and hacked at the timbers. The pirates, as darkness approached, began to retreat. The Spaniards shouted to them from the walls: “Come on, you English devils; you heretics; the enemies of God and of the king. Let your comrades, who are behind, come also. We will serve them as we have served you. You shall not get to Panama this time.”
