The piratical cruisers belonging to Algiers had long been the terror of the merchantmen of all nations. The Algerines not only plundered but massacred the crews of the vessels they captured, and it was supposed that many hundreds had fallen into their power. Their crowning act of atrocity was the murder of the crews of three hundred small vessels engaged in the coral fishery off Bona, near Algiers, who, being Christians, had landed to visit a church. At length the British Government determined to put a stop to their proceedings, and Lord Exmouth, who had just returned to England, after having compelled the Dey of Tunis to restore 1792 slaves to freedom, and to sign a treaty for the abolition of Christian slavery, was appointed to the command of a fleet which sailed from Plymouth on the 28th of July, 1816, with his flag flying on board the _Queen Charlotte_, of 100 guns, Captain James Brisbane. During the passage out, every ship in the fleet was exercised with the great guns, firing at a target hung from the end of the fore-topmast studdingsail-boom rigged out for the purpose, so that they became unusually expert. Lord Exmouth's fleet consisted of only five line-of-battle ships, with the 50-gun ship _Leander_, four frigates, and several sloops of war and bomb-vessels. Misled by the charts, which were altogether defective, Lord Nelson had required ten sail of the line, and the same number of bomb-vessels, when he proposed to attack Algiers, but the harbour and fortifications had lately been surveyed by Captain Warde, who had found the entrance of the harbour much narrower than had been supposed. The fortifications were, however, formidable in the extreme, the batteries defending the town bristling with several tiers of heavy guns, while powerful forts commanded the approaches. On the mole alone were upwards of 200 guns, and altogether 500 guns, few being smaller than 24-pounders, defended the piratic city. On reaching Gibraltar, Lord Exmouth found a Dutch squadron, Vice-Admiral Van de Cappellon, who entreated leave to co-operate with him, commanding it. After some delay owing to contrary winds, on the 14th of August the English and Dutch fleets, accompanied by several additional gunboats, sailed for Algiers. On their way they met the _Prometheus_ sloop of war, Captain Dashwood, which had on board the wife, daughter, and infant child of the British consul, Mr McDonnell. The two ladies, disguised in midshipmen's uniforms, had with great difficulty escaped, but as they were passing through the gateway the infant, who had been concealed in a basket, uttering a cry, was detained and carried to the dey. It should be recorded as a solitary instance of his humanity that it was sent off the next morning to its mother by the dey. The surgeon of the _Prometheus_ with three midshipmen and the crews of two boats, consisting in all of eighteen persons, had been detained.
