Tarifa is believed to have been a settlement of the Phœnicians. It derives its present name from Tarik, who first led the Moors into Spain, and who is said to have built the castle. The town had long· been declining, till the late wars in which Spain had been involved with England, in consequence of her unhappy connexion with France, gave it a new importance: for a little island which stands out boldly into the Straits off the town rendered it a favourable station for gun boats; and during the late war these boats inflicted greater losses upon the trade of Great Britain than it suffered from all the fleets of all her enemies. There were two half-moon batteries and a martello tower on the island; but when the Spaniards at the commencement of this dreadful struggle formed their alliance with Great Britain, these works, with the whole line of defence along the Straits, were dismantled, lest the French should at any time turn it against the best ally of Spain. The enemy occupied no point which in so great a degree commanded the straits; and Soult was now the more desirous of obtaining it, because he was at this time negotiating with Morocco, and the possession of Tarifa, which is only five leagues distant from Tangiers, would render it impossible for England with all her naval means to prevent him from receiving corn; and thus the difficulty of supplying the French armies would be greatly lessened, if not altogether removed. ♦TARIFA REGARRISONED BY THE ENGLISH.♦ The little garrison which had saved this important place was withdrawn for the expedition under Generals Lapeña and Graham, and when the latter re-entered the Isle of Leon, he left Tarifa uncovered; but General Colin Campbell a second time secured it, by sending thither the marines from the ships at Gibraltar. Soon after it was re-garrisoned, Major King of the 82nd was appointed to the command, and he and the Spanish governor, D. Manuel Daban, delayed not to take precautions against a danger, the approach of which now began to be apprehended. Piquets were placed at La Pena, at Facinas, and Port Alanca, and provisions were laid in for a siege. The first movement of the enemy indicated their ultimate object; D. Antonio Begines de los Rios, an officer who had distinguished himself daring General Lapeña’s expedition, and who was now stationed at Algeziras, made a representation of the approaching danger, and General Campbell directed that some field works should be thrown up on the island to secure a retreat, in case a retreat should be unavoidable. These works excited some jealousy in the governor; but Major King explained to him their use and necessity; and Ballasteros, who inspected them about the same time, expressed in animated terms his gratitude to the British nation, seeming at that time, like a brave and generous man, to feel no petty suspicions, or lingering of old prejudices, or resentment of false and ill-directed pride. ♦COL. SKERRETT AND COPONS ARRIVE THERE.♦
