On the night of the eighth day after the entrance of the allies into Madrid, the news of that event reached Cadiz, where it excited among the inhabitants the joyful hope of being speedily delivered from the blockade: and deeper emotions in those exiles who had left their houses and families in the metropolis. On the 24th the French broke up the siege; they threw shells during the preceding night; those which were filled with lead and discharged from howitzers with a velocity of about 2000 feet per second, ♦SIR HOWARD DOUGLAS’S NAVAL GUNNERY, P. 61.♦ ranged to the astonishing distance of three miles. They burst their guns by overcharging them, placing their muzzles one against another and exploding them by means of portfires and trains; and thus almost the whole of their artillery between Chiclana and Rota, consisting of 600 pieces, were rendered unserviceable. Many, however, were left uninjured for the Spaniards to take possession of, as well as thirty gun-boats, and a great quantity of stores. The necessity of this retreat had been foreseen by Soult as soon as he was informed of the battle of Salamanca. Before that action he had been meditating another attack upon Tarifa, as a place from whence he could easily communicate with Tangiers and the Barbary coast, and thus secure supplies for feeding the army under his command. Sir Rowland Hill’s movements withdrew him from this project: and after Marmont’s defeat he prepared to abandon Seville, but to hold the Carthusian convent there, which he occupied as a citadel. Strong working parties were employed in adding to its defences, while at the same time the French packed up their public documents and their private plunder for removal. But on this occasion the Spaniards were on the alert. ♦MOVEMENT OF LA CRUZ MOURGEON AND COL. SKERRETT UPON SEVILLE.♦
