On the 28th of September the combined army of French and Americans came in sight of York Town, and encamped about two miles from the outworks. The next morning they extended themselves towards the left of Cornwallis, but cautiously; and the English pickets slowly retired within the outer lines at their approach. That evening Cornwallis received a despatch from Sir Henry Clinton, dated September 24th, which gave the cheering expectation that he was duly sensible of the imminence of the danger, and of his responsibility. He said:"At a meeting of the general and flag officers held this day, it is determined that above five thousand men, rank and file, shall be embarked on board the king's ships, and the joint exertions of the navy and army made in a few days to relieve you, and afterwards to co-operate with you. The fleet consists of twenty-three sail of the line, three of which are three-deckers. There is every reason to hope that we start on the 5th of October." On this promising intimation of speedy aid, Cornwallis immediately drew in his small force from the extended outworks, and concentrated them within the entrenchments round the town. Undoubtedly it was a measure calculated to save much life, which must have been lost in defending outworks too widely extended for the enclosed force; but it encouraged the Americans, who did not expect to gain them thus easily. Two thousand men took up their ground before Gloucester. Round York Town itself Washington, Rochambeau, Lafayette, and St. Simon concentrated their forces. On the night of the 1st of October, the French on the right and the Americans on the left drew nearer, and commenced breaking ground. Six days were then spent in bringing from the ships fifty pieces of cannon, some of them very heavy, ammunition, and other military stores; in fact, as much preparation was made for carrying this single post as if it had been a regular and first-rate fortress. On the night of the 6th of October the French and Americans began casting up their first parallel within six hundred yards of Cornwallis's lines. By the 9th of October their trenches and batteries were completed, and that afternoon they opened a tremendous fire on the town. Cornwallis replied to them with vigour,[283] but he found many of his guns on the left silenced, and his works greatly damaged. On the night of the 11th the enemy began their second parallel within three hundred yards of the lines. In its progress, for three days, Cornwallis committed much havoc amongst them by opening fresh embrasures for guns, and pouring an incessant shower upon them of balls and shells. Two redoubts on the left flank of the British more particularly annoyed them, and Washington determined to carry these by storm. Of course they were carried, and their guns then turned on York Town.
No sooner did Howe return to port than he had orders to sail in aid of Gibraltar, which was not only greatly in need of stores and provisions, but was menaced by the combined armies and fleets of France and Spain with one great and overwhelming attack. The evil fortune of England did not yet, however, seem to have disappeared, for the Royal George, the finest vessel in the service, went down in a sudden squall. But this awful catastrophe did not hinder the sailing of Lord Howe. He had by great exertion mustered a fleet of thirty-four sail-of-the-line, and on the 11th of September steered out for Gibraltar. For upwards of three years this famous rock had now been beleaguered. After the relief thrown in by Admiral Darby, the Spaniards, despairing of reducing the garrison by blockade, determined to destroy the town and works by a terrific bombardment. This bombardment was, accordingly, opened with unexampled fury, and continued incessantly for days and weeks. The town was set on fire, and numbers of houses consumed; the damage done to the ramparts and public buildings was appalling. General Elliot displayed the utmost temper and skill during this bombardment, as he did throughout the whole siege. He continued by night, and at other opportunities, to repair actively the damages done; and, reserving his fire for occasions when he saw a chance of doing particular damage, he caused the enemy to wonder at the little impression that they made.
