The outline of the attack having been arranged, the plan was drawn out by the Duc de Crillon, and submitted for approval, first to the Court of Madrid, and afterward to the King of France. Subsequently the details were very materially altered, but the principle remained the same. The method originally proposed was as follows: "The plan for taking Gibraltar, presented by Crillon, with the opinion of the minister, was imparted, by order of his majesty, to France, by the hand of Aranda, and, it being approved of, that Court offered twenty-seven auxiliary ships. According to this plan the assault will be conducted in the following manner: Brigadier Don Ventura Moreno will command the fire of the fleet. The vanguard of the combined squadron will be commanded by Señor Cordova, and among the divisions that compose it will be included the third of twelve fireproof ships, which will anchor in Algeciras until Señor Alvarez completes the sixty paces of intrenchment opposite the fortress. Our ships will then attack; four by the Europa Point, two by the New Mole, their fire being supported by that of the gun- and mortar-boats and bomb-ketches, which will hold themselves in readiness to support where it may be required. "At a given signal the fire from our whole line will open with that of the intrenchment, which will not cease until a breach shall have been made at the Europa Point. The battering-ships will not be allowed to quit their respective posts till they require relief, and they will then retire to Algeciras, whence others will proceed to supply their places, taking up the same points. The officer who shall act counter to his orders will be removed from his post without its being referred to the King. The breach having been made, the commander-in-chief, the Duc de Crillon, will notify to the governor the surrender of the fortress; and should he consent to the capitulation, the preliminaries will be arranged, conceding to him military honors; if he persist in the defence, the operations will continue in the following manner:
