To the southward of that, and nearly in a line with the pier, was the lighthouse battery, of three tiers, mounting forty-eight guns, next to which was the eastern battery, mounting sixty-six guns in three tiers, flanked by four other batteries, of two tiers, mounting altogether sixty guns, and on the mole-head were two long 68-pounders, described as being twenty feet in length. The total number of guns on the mole and pier was at least 220, composed of 32, 24, and 18-pounders.
The “fish-market” battery, about 300 yards west from the south mole-head, mounted fifteen guns, in three tiers. Between that and the southern extremity of the city were two batteries of five guns each. Beyond the city, in this direction, was a castle and three other batteries, mounting altogether about seventy guns. In the rear of the city, and on the heights, were several other batteries; so that the total number of guns mounted for the defence of this fastness of robbery, oppression, and cruelty, exceeded 1000.
On the 27th of August, at daybreak, the city of Algiers was in sight, but the ships were lying nearly becalmed. A boat in charge of a Lieutenant was despatched to the Dey, to demand compliance with the following conditions: the abolition of Christian slavery; the release of all Christian slaves; the repayment of the money recently exacted for the redemption of Neapolitan and Sardinian slaves; peace with the King of the Netherlands; and the immediate liberation of the English Consul and the officers and boats’ crews of the Prometheus.
The boat with the flag of truce was towed in shore, and was met, at 11 A. M., near the mole, by an Algerine boat, in which was the Captain of the Port, who promised a reply in two hours. In the meantime the sea breeze sprang up, and the whole fleet stood into the bay, and hove to, about a mile from the batteries. At 2 P. M., no answer having been received, the boat sent with the message made signal to that effect, and returned to her own ship.
Lord Exmouth at once demanded, by signal, if all the ships were ready, and being answered in the affirmative, the fleet bore up for the attack, in the order precisely laid down.
About half-past two in the afternoon the flag-ship, Queen Charlotte, anchored, with springs, about fifty yards from the mole-head; and while in the act of making a warp fast to an Algerine brig on shore at the mouth of the harbor, a shot was fired at the ship; and at the same moment two shots from the opposite end of the mole were fired at the Impregnable, and other ships, as they were advancing to take their stations.
Lord Exmouth, unwilling to sacrifice the mass of Algerine townspeople standing on the parapet of the mole, and gazing with astonishment at the strange ships, waved his hand to them to descend, and at once gave orders to commence firing, when the action became general, as soon as the guns would bear.
On the Queen Charlotte’s port bow lay the Leander, 50, occupying the place in line of a line-of-battle ship, with her starboard after guns bearing upon the mole, and her forward guns upon the “fish-market” battery.
Ahead of the Leander was the Severn, 40, her starboard broadside bearing full upon the “fish-market” battery. Close to the Severn was the Glasgow, 40, whose port guns bore upon the town batteries. On the port quarter of the Queen Charlotte was the Superb, 74, her starboard broadside bearing on the 60-gun battery next to the one on the mole-head. It was intended that the Impregnable, 98, and Albion, 74, should take their places close astern of the Superb, but the former, not being sufficiently up when the firing began, brought up considerably outside of her appointed station, and beyond the line of bearing within which the attacking force had been ordered to assemble. The Impregnable, in consequence, lay exposed, at the distance of five hundred yards, to the lighthouse battery of three tiers, as well as to the eastern battery of two tiers. The Minden pushed on and dropped her anchor in the space between the Impregnable and Superb, on the port quarter of the latter. The Albion brought up near the Impregnable, but weighed again, and, about three o’clock, anchored close astern of the Minden.
The end of her stream cable was then passed out of the gun-room port of the latter, by which the Albion was hove close to the stern of the Minden.
