On the very day of Cornwallis' surrender, Clinton sailed from New York with reinforcements. He had been perfectly aware of Cornwallis' extreme peril and was anxious to relieve him, but the fleet had sustained considerable damage in the battle with de Grasse and some time was necessarily spent in repairing it. During that interval four ships-of-the-line arrived from Europe and two from the West Indies. At length Clinton embarked with 7,000 of his best troops, but was unable to sail from Sandy Hook till the 19th (1781), the day on which Cornwallis surrendered. The fleet, consisting of twenty-five ships-of-the-line, two vessels of fifty guns each, and eight frigates, arrived off the Chesapeake on the 24th (October, 1781), when Clinton had the mortification to be informed of the event of the 19th. He remained on the coast, however, till the 29th, when, every doubt being removed concerning the capitulation of Cornwallis, whose relief was the sole object of the expedition, he returned to New York. While Clinton continued off the Chesapeake, the French fleet, consisting of thirty-six sail-of-the-line, satisfied with the advantage already gained, lay at anchor in the bay without making any movement whatever. Washington, considering the present a favorable opportunity for following up his success by an expedition against the British army in Charleston, wrote a letter to Count de Grasse on the day after the capitulation, requesting him to unite his fleet to the proposed armament and assist in the expedition. He even went on board the admiral's fleet to thank him for his late services in the siege and to urge upon him the feasibility and importance of this plan of operations. But the orders of his court, ulterior projects, and his engagements with the Spaniards put it out of the power of the French admiral to continue so long in America as was required. He, however, remained some days in the bay in order to cover the embarkation of the troops and of the ordnance to be conveyed by water to the head of the Elk. [5] Some brigades proceeded by land to join their companions at that place. Some cavalry marched to join General Greene, but the French troops, under Count Rochambeau, remained in Virginia to be in readiness to march to the south or north, as the circumstances of the next campaign might require. On the 27th the troops of St. Simon began to embark, in order to return to the West Indies, and early in November Count de Grasse sailed for that quarter.
