At seven o'clock the headmost ships were dismasted; a fire-raft was observed dropping down from them on the Orion. Her stern-boat having been shot through, and the others being on the booms, it was impossible to have recourse to the usual method of towing it clear: booms were then prepared to keep it off. As it approached, however, the current carried it about twenty-five yards clear of the ship. About half-past eight, just as the Peuple Souverain, which had been the Orion's opponent, had dropped to leeward, a suspicious ship was seen approaching the Orion in the vacant space which the vanquished one had occupied. Many on board were convinced of her being a fire-ship of the enemy, and Sir James was urged to allow the guns to be turned upon her. Happily he himself had stronger doubts of her being such than those who pressed the reverse. He ordered a vigilant watch to be kept on her movements; and when the darkness dispersed, she was discovered to be the Leander. Distinguishing lights were hoisted, and the Orion continued to engage Le Franklin from fifty minutes past six o'clock to a quarter before ten. The action was general, and kept up on both sides with perseverance and vigour, when the enemy's fire began to slacken, and the three-decker was discovered to be on fire. At ten the firing ceased; the ship opposed to the Orion having surrendered, as also all the van of the enemy. Preparations were now made to secure the ships from the effects of the expected explosion.--The ports were lowered down, the magazine secured, the sails handed, and water placed in various parts to extinguish whatever flames might be communicated. The unfortunate ship was now in a blaze; at half-past eleven she blew up, and the tremendous concussion was felt at the very kelsons of all the ships near her. The combatants on both sides seemed equally to feel the solemnity of this destructive scene. A pause of at least ten minutes ensued, each engaged in contemplating a sight so grand and terrible. The Orion was not far off; but, being happily placed to windward, the few fiery fragments that fell in her were soon extinguished. Her vicinity to the L'Orient was the happy means of saving the lives of fourteen of her crew, who, in trying to escape the flames, sought refuge in another element, and swam to the Orion, where they met a reception worthy the humanity of the conquerors. The generous, warm-hearted sailors stripped off their jackets to cover these unfortunate men, and treated them with kindness, proving that humanity is compatible with bravery.
