The British Admiral being thus undisturbed, passed the morning in arranging his forces according to the plan previously resolved on, which was to concentrate their effects entirely on the mole and shipping, his object being to destroy the fortifications and navy as soon as possible, and to do no injury which could be avoided to the town. His own ship the Queen Charlotte of one hundred guns was drawn up and anchored within fifty yards of the southern extremity of the mole, the others were distributed at points more or less distant from the batteries, but all much nearer than had been customary on previous occasions of a similar nature. At three o'clock the action was begun by a shot from the mole at the Queen Charlotte which being instantly returned the action became general. In twenty minutes the marine batteries were silenced, and the defenders endeavoring to escape from them along the causeway, were mowed down by the guns of the ships; they however returned to their posts and kept up a desultory fire throughout the afternoon. At eight o'clock the whole of the Algerine shipping in the harbor was in flames, presenting a spectacle of terrific sublimity; the fortifications of the mole were soon after abandoned by the defenders, being reduced to an untenable state by the effects of the bombardment and of the explosion vessels. At ten o'clock the ammunition of the attacking fleet began to fail, but the British Admiral saw that sufficient damage had been done; he therefore took advantage of a breeze which sprung up at that time and drew off his ships. The next morning Lord Exmouth again sent to know whether the Dey would accept the terms offered on the 27th. Omar declared his own unwillingness to yield, and his readiness to abandon the city in preference; but he was overruled by his Divan, and having reluctantly agreed to submit to them, the Chevalier d'Ankarloo the Swedish Consul, (since Chargé d'Affaires of Sweden in the United States,) was requested by him to go on board the British fleet and make the necessary arrangements in behalf of Algiers. On the 29th a convention was signed, the conditions of which were--the delivery of all slaves in Algiers without ransom, and the abolition of christian slavery in those dominions for ever--the restitution of all sums paid as ransom within the year 1816, including three hundred and fifty-seven thousand dollars which had been paid by Naples and twenty-five thousand five hundred by Sardinia, according to the terms of the treaty signed in April preceding--reparation to the British Consul for all losses sustained by him in consequence of his confinement, and an apology to be made by the Dey publicly in presence of his ministers and officers.
