Whatever impression these observations may have made on the Count, they could not change the determination he had formed.
General Greene, in his representation of this conversation, stated that the principal officers on board the fleet were the enemies of D'Estaing. He was properly a land officer, and they were dissatisfied with his appointment in the navy. Determined to thwart his measures, and to prevent, as far as could be justified, his achieving any brilliant exploit, they availed themselves of the letter of his instructions, and unanimously persevered in advising him to relinquish the enterprise, and sail for Boston. He could not venture, with such instructions, to act against their unanimous opinion; and, although personally disposed to re-enter the harbour, declined doing so, and sailed from the island.
On the return of Greene and Lafayette, Sullivan made yet another effort to retain the fleet. He addressed a second letter to the Admiral, pressing him, in any event, to leave his land forces. The bearer of this letter was also charged with a protest signed by all the general officers in Rhode Island except Lafayette, the only effect of which was to irritate D'Estaing, who proceeded, without delay, on his voyage to Boston.
In consequence of the departure of the French fleet, Sullivan raises the siege of Newport.
Thus abandoned by the fleet, Sullivan called a council of general officers, who were in favour of attempting an assault if five thousand volunteers who had seen nine months service could be obtained for the enterprise; but the departure of the fleet had so discouraged the militia, that this number could not be procured; and, in a few days, the army was reduced by desertion to little more than five thousand men. As the British were estimated at six thousand, it was determined to raise the siege, and retire to the north end of the island, there to fortify, and wait the result of another effort to induce D'Estaing to return.
August 28.
In the night of the 28th, the army retired by two roads leading to the works on the north end of the island, having its rear covered by Colonels Livingston and Laurens, who commanded light parties on each.
August 29.
Early next morning the retreat was discovered by the British, who followed in two columns, and were engaged on each road by Livingston and Laurens, who retreated slowly and kept up the action with skill and spirit until the English were brought into the neighbourhood of the main body of the Americans, drawn up in order of battle on the ground of their encampment. The British formed on Quaker Hill, a very strong piece of ground, something more than a mile in front of the American line.
Sullivan's rear was covered by strong works; and in his front, rather to the right, was a redoubt. In this position, the two armies cannonaded each other for some time, and a succession of skirmishes was kept up in front of both lines until about two in the afternoon, when the British advanced in force, attempted to turn the right flank, and made demonstrations of an intention to carry the redoubt in front of the right wing. Action between Sullivan and the British army.General Greene, who commanded that wing, advanced to its support, and a sharp engagement was continued for about half an hour, when the British retreated to Quaker Hill. The cannonade was renewed, and kept up intermingled with slight skirmishing until night.
