So sure were the allies of victory that they debated among themselves as to "how many hours" the garrison could keep up a resistance. Twenty-four hours was the limit, and when the French commander, less sanguine than the naval constructors and engineers, thought it might be even _two weeks_ before the place fell, he was the subject of general ridicule.
Taking for granted that the fire of the garrison would soon be silenced, precise directions were given about the landing of the storming party. As soon as a break was made, the grenadiers were to mount the walls. It was especially ordered that strong bodies of troops should _advance rapidly and cut off the retreat_ of the garrison, which might otherwise flee to the heights of the Rock, and keep up for a while longer the hopeless resistance. The victory must be complete.
On the other hand, the garrison was roused to greater exertion by the greater danger. Its ardor was excited also by what was passing in other parts of the world. War was still raging in both hemispheres, with the usual vicissitudes of victory and defeat. England had lost America, but her wounded pride was soon relieved, if not entirely removed, by a great victory at sea. Cornwallis surrendered at Yorktown, in October, 1781, and only six months after, in April, 1782, Admiral Rodney (the same who had relieved Gibraltar only two years before) gained a victory in the West Indies over Count de Grasse, which almost annihilated the French fleet, and assured to England, whatever her losses upon land, the mastery of the seas. The tidings of this great victory reached Gibraltar, and fired the spirit of every Briton. The Governor was now sixty-four years old, and the events of the last three years might well make him feel that he was a hundred. But his youth returned in the great crisis that was upon him. Both Governor and garrison burned to do something worthy the name and fame of Old England. The opportunity soon came.
Though the battering ships were regarded as invincible, yet to make assurance doubly sure the French and Spanish fleets had been quadrupled in force. If any man's heart had been trembling before, it must have failed him on September 12, 1782, when there sailed into the bay thirty-nine ships of the line, raising the naval armament to fifty line-of-battle ships, with innumerable smaller vessels--the largest naval armament since the Spanish Armada--supported on land by an army of forty thousand men, whose batteries, mounted with the heaviest ordnance, stretched along the shore.
