old, much to the annoyance of many British officers, but five days later Cornwallis arrived and took command. He now had a combined command of 6,000 men, but his plans for a campaign in Virginia were only to last until late June, when orders reached him from Clinton. Clinton was worried about the prospect of a combined American and French attack on New York, while he was advised by the navy that they did not have a good winter anchorage near to New York, and so he ordered Cornwallis to fortify a naval base on the Chesapeake, while warning that he may soon need some troops from Cornwallis. During July Cornwallis examined potential sites at Yorktown and Portsmouth. This period was one in which the British commanders were at odds. Cornwallis was not convinced that a base on the Chesapeake had any value unless for a full scale invasion of Virginia, while Clinton did not see the value of such a campaign, and was still concerned about an attack on New York, even though his own forces still outnumbered the combined American and French forces. While warning that the position was not suitable for defence and that he had not enough men to build the defences, on 2 August Cornwallis landed his troops at Yorktown, having decided not to send any to Clinton, and began to fortify his position.now began the campaign that was to seal his reputation and effectively end the war. He had hoped to launch an attack on New York, and in May Rochambeau had agreed to move his troops from Newport to aid this attack. However, although some activity took place around New York in July, the British position was too strong and little came of the plans. Since June Washington had know that Admiral Grasse was heading for America from Brest in France, but his actual destination, and the effect he would have, was unknown. On 14 August, news arrived that Grasse was sailing for the Chesapeake, with twenty-nine ships and three thousand men. Combined with Washington's own army, and Rochambeau's army and fleet, it would be possible for the allies to gain a decisive advantage in the Chesapeake for long enough to defeat Cornwallis.British made an attempt to defeat the French fleet. De Grasse sailed from Saint Domingue with twenty-eight ships on the line on 5 August, reaching the Chesapeake on 30 August. The next day Admiral Graves in command of the combined British fleet sailed from New York. The two fleets came together on 5 September (battle of the Capes). In a two hour battle neither side lost a ship, but both suffered serious damage, and the British were forced from the area, leaving Cornwallis isolated by sea. Clinton had also failed to warn him that Washington may be marching south, still convinced an attack on New York was imminent. Cornwallis thus decided against an attempt to fight his way out. However, Washington had started to move his men south in mid-August, and by the middle of September Washington, Rochambeau, Lafayette and de Grasse were all conce...
