The fore and main-topsails, closely-reefed, were now let fall, and, with great exertion, extended to their yard-arms; the two ships being thus on an equality of sailing, continued to run side by side, exchanging every now and then strong and noisy proofs of their vicinity, by an irregular discharge of their guns, as they could be brought to bear in the heavy sea that was running, and as they gained a momentary glance of each other. It was fearful thus fighting amid darkness on the raging ocean, which, of itself, afforded dangers sufficient to encounter; yet 'twas a scene which made the heart of Don Luis throb with wild excitement, such as he had never before experienced--the howling of the tempest, the muttered growls of the thunder, the roar of the guns, their bright flashes, and the forked lightning, which played around the masts of the ships, as if to remind them that they were liable to destruction from a far greater Power than that of which their own mortal efforts were capable. As yet the guns of the enemy had done no more damage than cutting some of the running rigging; but it was impossible to say what mischief those of the corvette had inflicted in retaliation, though, from the pertinacity of her opponent, it was supposed to have been but slight. "If yonder ship does not carry the devil and a whole host of his imps on board, she must be an Englishman," said the old Pilot, coming up to the captain's side; "for no other mortals would have dreamed of engaging in a night like this, and she must fancy that she has got alongside a Frenchman: there's no doubt of it." "I know not of what nation he is, though I am pretty certain of his mortal qualities," answered the Captain. "But if he is an Englishman, I wish we could find some way of letting him know we are friends, for he will not leave us till he has either sunk us or blown us out of the water, if we cannot manage to treat him in the same way." "Where is the enemy? Where is the skulking foe?" was echoed along the decks by some of the crew; for since the last discharge of her guns their opponent had disappeared in the impenetrable darkness which surrounded them, increased by a thick mist, which came driving past; while others exclaimed, "Holy Virgin, that was no mortal bark! Ah, she has vanished as suddenly as she appeared! May the saints protect us, and gain us forgiveness for our sins; for we have been fighting with the powers of darkness?" "That fellow is no Englishman, or he would not for a moment have lost sight of us, if he thought us an enemy," cried the Captain. "No, no, I know those haughty islanders too well. He is some Frenchman, perhaps, who, from the few guns we used, mistakes us for a smaller vessel of the foe, and will be down again upon us directly. We must fight our whole broadside, Senhor Alvez, at every risk, to undeceive him as to our size; and we will take care that he does not run away from us, whoever he may be."
