Her last exploit was the capture of his majesty's schooner St. Lawrence, carrying fifteen guns. The latter was on her way to New Orleans, with some soldiers, marines, and gentlemen of the navy as passengers. The Chasseur had only six twelve-pounders and eight short nine pound carronades, having been compelled a short time before, when hard pressed by an English frigate, to throw over nearly all her twelve pound carronades. Captain Boyle had no suspicion of the true character of the vessel when he gave chase, for her ports had been closed on purpose to deceive him. He therefore stood boldly on till he got within pistol-shot, when the schooner suddenly opened ten ports on a side and poured in a destructive fire. At the same time the men who had been concealed under the bulwarks leaped up and delivered a volley of musketry. Captain Boyle, discovering what a trap he had been beguiled into, determined at once to stay in it, and ranging alongside within ten yards, opened a tremendous fire with his batteries and musketry. The vessels were so near each other that the voices of officers and men could be distinctly heard, even amid the crashing cannonade. That little privateer exhibited a skill and practice in gunnery unsurpassed by any frigate, and superior to any vessel in the English navy. The enemy was completely stunned by the rapidity and destructive effect of her fire, and in eleven minutes was a perfect wreck. Captain Boyle then gave the command to board, when the flag was struck. In this short space of time the Chasseur had strewed the deck of that schooner with nearly half of her crew, killed and wounded. Our privateers had greatly the advantage of the English, not only in artillery but in musketry--our men firing with much surer aim than theirs.
