The ships of the French Republic which sustained this attack were the Formidable, 84, Citizen Linois; Dessaix, 74, Moncousu, killed; L'Indomptable, 84, La Londe, killed; the frigate Muiron, 36, Martinencq; five Spanish gun-boats damaged, and two sunk. In the French ships, three hundred and six killed; one hundred and eighty-four wounded. We suppose in the English squadron above five hundred are killed, and from two hundred and seventy to two hundred and eighty wounded. MADRID GAZETTE EXTRAORDINARY. Merida, 10 July 1801. The general commandant of the camp at St. Roque, in a despatch of the 6th instant, transmitted by a courier extraordinary, communicates an account of an action which has been fought between six sail of the line, and other vessels of war, belonging to the English, and the French squadron of three ships of the line, and one frigate, lying at anchor in the harbour of Algeziras; and of the glorious result which has taken place for his Majesty's arms, and those of the Republic, his ally. About eight in the morning of that day, (viz. the 6th,) there were seen, coming out of Gibraltar, one ship of eighty-four guns, five of seventy-four, a lugger of sixteen, another of ten, and a polacre of ten, two armed launches, and fourteen boats. This force, under the command of a Rear-admiral, stood into Algeziras, for the purpose of attacking the French squadron then anchored in that port, which, as has been already stated, consisted of three sail of the line, and one frigate. The commanders of this squadron, being aware of the enemy's intention, made their dispositions for defence, placing themselves, as well as they were able, under the cover of our batteries, and waiting in this position for his approach. The action commenced at nine; it was very obstinate and bloody on both sides, and likewise on the part of our batteries, which decided the fate of the day. The action was continued till two in the afternoon, at which hour the English drew off with the loss of one ship of the line; taking in tow another, which was dismasted and damaged in the hull; and having sustained very great loss and damage in the rest of their vessels. Their loss in men must have been considerable, as it is certain that a great number were killed and wounded on board all the ships. The French also have been equal sufferers, the killed and wounded in their squadron being estimated at eight hundred: that of our troops has been less; out of the whole, only the royal regiment of Ronda has lost eleven men.
