[Footnote 81: In pursuance of these orders, Wayne was detached to the south side of James River, under the pretext of reinforcing Greene, but was ordered to maintain a position which would enable him to intercept and oppose the march of Lord Cornwallis, should he attempt to force his way to Charleston. Lafayette was on the alert to co-operate with Wayne in the event of such a movement.--_Cor. with Lafayette._] Conformably to the intelligence communicated by the Count de Barras, the Count de Grasse arrived in the Chesapeake late in August with twenty-eight ships of the line and several frigates. At Cape Henry he found an officer despatched by Lafayette with full intelligence of the situation of the armies in Virginia. Lord Cornwallis had collected his whole force at Yorktown and Gloucester Point, which he was fortifying assiduously; and the Marquis had taken a position on James River. In consequence of this information, four ships of the line and several frigates were detached to block up the mouth of York River, and convey the land forces brought from the West Indies, under the command of the Marquis de St. Simon, up the James to join Lafayette, who, on receiving this reinforcement, took post at Williamsburg. In the mean time, the fleet lay at anchor just within the capes. On the 25th of August the Count de Barras[82] sailed from Newport for the Chesapeake. [Footnote 82: This admiral was the senior of De Grasse, to whom the command of the expedition had been entrusted, and was therefore authorized by the minister of marine, to cruise on the coast of Newfoundland while his ships should join the grand fleet. He preferred serving under his junior officer.--_Cor. of Lafayette._] Rodney was apprized of the destination of De Grasse, but seems not to have suspected that the whole fleet would sail for the continent of America. Supposing therefore that a part of his squadron would be sufficient to maintain an equality of naval force in the American seas, he detached Sir Samuel Hood to the continent with only fourteen sail of the line. That officer arrived at Sandy Hook on the twenty-eighth of August. Admiral Greaves, who had succeeded Arbuthnot in the command of the fleet on the American station, lay in the harbour of New York with seven ships of the line, only five of which were fit for service. On the day that Hood appeared and gave information that De Grasse was probably on the coast, intelligence was also received that De Barras had sailed from Newport. The ships fit for sea were ordered out of the harbour; and Greaves, with the whole fleet, consisting of nineteen sail of the line, proceeded in quest of the French. Not suspecting the strength of De Grasse, he hoped to fall in with one or the other of their squadrons, and to fight it separately.
