Great was the exasperation in the American camp. Sullivan's vexation found indiscreet expression in a general order, in which he hoped the event would prove America "able to procure that by her own arms which her allies refuse to assist in obtaining." But the insubordination of the volunteers now came in to complicate the matter. Some 3,000 of them, despairing of success and impatient at being kept from home in harvest time, marched away in disgust and went about their business, thus reducing Sullivan's army to the same size as that of the enemy. The investment of Newport, by land, had already been completed, but the speedy success of the enterprise depended upon a superiority of force, and in case of British reinforcements arriving from New York the American situation would become dangerous. Upon these grounds, Sullivan, on the 28th, decided to retreat to the strong position at Butts Hill, and await events. Lafayette mounted his horse and rode the seventy miles to Boston in seven hours, to beg his kinsman to return as soon as possible. Estaing despaired of getting his ships ready for many days, but, catching a spark of the young man's enthusiasm, he offered to bring up his troops by land. Fired with fresh hope, the young marquis spurred back as fast as he had come, but when he arrived on the scene of action all was over. As soon as Sullivan's retreat was perceived the whole British army gave chase. After the Americans had retired to their lines on Butts Hill, Sir Robert Pigot tried to carry their position by storm, and there ensued an obstinate fight, in which the conditions were in many respects similar to those of Bunker Hill; but this time the Americans had powder enough, and the British were totally defeated. This slaughter of their brave men was useless. The next day Sullivan received a dispatch from Washington, with the news that Clinton had started from New York with 5,000 men to reinforce Sir Robert Pigot. Under these circumstances, it was rightly thought best to abandon the island. The services of General Glover, who had taken Washington's army across the East River after the defeat of Long Island, and across the Delaware before the victory of Trenton, were called into requisition, and all the men and stores were ferried safely to the mainland; Lafayette arriving from Boston just in time to bring off the pickets and covering-parties. The next day Clinton arrived with his 5,000 men, and the siege of Newport was over. * * * * * [Portrait: John Glover B General] [Sidenote: Unpopularity of the French alliance]
