The ravelins upon which the Marines worked, within ten yards of the enemy's approaches, were in a progress of completion between the 2d and 8th of May, and were each night assailed by the French, who were as often repulsed, in nine different attempts to storm, with immense slaughter. The gallantry of my Corps, in all, exceeds praise. Many sorties were made to incommode their covering works, and most unprecedented were the bodily fatigues and mental anxiety of all. The republicans had some time past opened with heavy guns, which they had received from Jaffa, and from which a serious impression was made upon the works of the garrison. Resorting to fresh expedients, Buonaparte tried to effect a new breach in the eastern curtain, by a sap and mine; but the unremitting activity of the brave defenders of Acre, by making approaches under ground, destroyed the frame-work and his hopes. Again directing his attacks upon the Tower, an effort to establish a lodgment in the glacis was once more unavailing. Fifty-one days of vindictive and unceasing contest, save those short intervals necessary to recruit exhausted nature, had elapsed, when the garrison beheld their long-expected reinforcements under Hassan Bey. Foiled in every essay to carry the place, Buonaparte saw with grief and disappointment this flotilla, which was to blast all his ambitious schemes, and to relieve his now almost worn-out opponents. With a desperate ardour, impelled by wounded pride, he lost not a moment to prepare and advance to the assault, in the sanguine idea that by one bold effort he might consummate his ardent wishes before Hassan's troops could land. At ten, on the night of the 7th of May, the carnage began. Mr. Scroder, Master's Mate of the Theseus, from an 18 pounder in the Light House Castle; a 24, under Mr. Jones, Midshipman of the Theseus, mounted in the north ravelin, and two 68 pound carronades, under the direction of Mr. Bray, carpenter of the latter ship, which threw shells from two germes in the Mole, added to the Turkish musquetry, committed dreadful havoc amongst the French columns in moving on to the attack. Much might be said were I to diverge upon the many chequered events of the night and the following day. The morning's dawn displayed the enemy's standard flying on the outer angle of the Tower, which their intrepidity had carried, having ascended on its ruins. Here they made a lodgment by two traverses across the ditch, constructed and filled with sand bags, and the bodies of their dead. Feeble is my panegyric of the unsurpassed heroism, the decisive resources, the conciliating address, and bold expedients of Sir Sidney Smith, during 25 hours of almost constant action. They have been but rarely equalled, and will never be outdone. He was well seconded by his able coadjutor Sir John Douglas, who combines a natural perseverance of character with the most manly judgment. Their virtues transcended to every subordinate rank, and animated all.
