But after sunset it appeared evident that the dauntless spirits of the buccaneers were not yet crushed, and that they meant to try again. The small army advanced in a compact square, the foremost line carrying fire-balls to throw at the palisades. Up they dashed, heedless of shots and arrows, which had fatal effect in thinning the ranks; but at first the assailants were quite impotent to effect any harm. The walls were well manned, and it was difficult to get near enough to throw in the fire-balls. Again there was a thought of retreat, when a curious accident caused the fight to be no longer advantageous only on one side. One of the pirates was wounded with an arrow, which, striking him in the back, pierced his body to the other side. With Spartan fortitude the man pulled it out, and, taking a little cotton, he wound it round the arrow, and, putting it in his musket, shot it back into the castle. This caused one of the smaller houses within the precincts to catch fire, which, being thatched with palm-leaves, easily ignited; and so eager was the fight that this was not at once perceived, till suddenly the flame shot upwards, sending a dull, lurid glow over the combatants. Unfortunately, the house was not far from the powder-magazine, and a smoking leaf was carried by the night wind towards this spot. In a few moments more both the besieged and besiegers paused in their work, for with a noise of terrific explosion the powder-magazine blew up, scattering destruction within the walls, and, what was even worse, shattering a large portion of the bank which protected the palisade. At this moment Carlo, who had been engaged in reloading a number of muskets, saw a sight which made him turn sick with fear. The fire was gaining ground; the flames, like hungry furies, appeared to leap from stake to stake of the strong palisade, and, further loosening the earth round the breaches made by the explosion, allowed great masses of earth to topple over into the ditch. ’Put out the fire! fetch water! hoist the bucket from the well!’ shouted Don Alvarez, frantically rushing from post to post. ’Keep up your spirits, my men; don’t fall back; hurl the first pirate who scales the ditch headlong down the cliff!’ These and many like orders were passed on; but from below came a desperate cheer from the pirates, who saw how the fire had done the hardest part of the work for them, and with renewed courage dashed once more forward. It was, indeed, a terrible sight; the fire that raged round the palisade was awful in its effects. The Spanish soldiers on one side struggled bravely to stand to their posts; while the pirates, still more determined, crawled along over the scorching earth, or literally ran the gauntlet of the fire, in order to pass into the enclosure; and a shout of triumph here and there told plainly where they had succeeded.
