Gallant Naval Exploit.
[From the fH?npiirce Tel .In our last we adverted to the accounts latel received fom the Mediterraneao, by which it appeared that the boats of his Majesty's Rship Ni4, Captaiin the lion. Robert Spencer, had succeedcd in destroying an Algerine vessel of war, under the batteries of Bona. We arehappy tohaeit in our power togivenow a more detailed accountof this eveat, written by an officeron the spot. The writer "We anchored aftor dark pretty close off the town, and the boats were seit away under command of Lieutenant Qain.' Owing to the darkness, and to the boats having taken a circuitous route, they did not reach the town until iatcs and then got on board a large lo.gun brig of war; they soon set ner in a blaze. At dav-light she had burned to the water's edge, she soon blew upandsunik in deep water, so that by seven in the morning there was no vestige of her left in sight. She was stronely moored head and stern with chains, at the distance of 20 yards fromn the fortn est, on which were mounted 40 pieces of cannon, none of which were furtlher than canister range, and some within her own length. Thegarrison consisted of 400 men, who were stationed with misketry at the embrazures, which looked dawn on the brig's decks: in short, the position was one of extra- ordinary strengthi. Nevertheless, the good order and regularitv of our men, and the judicious manner in which the approach was made, were suchI, that they got alongside, or nearly so, unperceived ; not a whisper was heard tiDl the enemy's first discharge of grape-shot, whiclh was answered by three cheers. A terrible fire was from thisi moment kept up, but Lieerenant Quin and his gallant companions did not leave her till she was iairly on fire fore-and-aft. and so hot that they were obliged to return to the boats. Not one was killed, and only a few slightly hurt. Strict orders were given by Captain Spencer, who suspected her situation to be what it proved, not to at- tempt bringing out the vessel; and it was fortunate that his orders on tnis point were imperative, since, had any discretion hbeen left, an endeavour to cut her out would have heen made, which, considering the manner ,n which she was secured to thie walls bV chains, must haveled to the uselessdestruction o' many valuablelives. The brig was enttirely empty, and in consequence floated so high out of the water that she was boarded with difficulty; but every thing was so well ar- ranged previously, that no confusion took place, and in all its parts no enterprise could ever have becn more complete and satisfactory in its results."
