This description of the retreat to Tiverton is taken from General Sullivan’s letter to the Continental Congress which was published in the Providence Gazette, September 26, 1778.
Sullivan justifies the retreat:
“Lord Howe and his fleet were approaching. In the morning of the 30th I received a letter from his Excellency General Washington, giving me notice that Lord Howe had again sailed with the fleet, and receiving intelligence at the same time that a fleet was off Block Island and also a letter from Boston, information me that the Count D’Estaing could not come round so soon as I expected, a council was called, and as we could have no prospect of operating against Newport with success, without the attendance of a fleet, it was unanimously agreed to quit the island until the return of the French squadron.
To make a retreat in the face of an enemy, equal, if not superior in number, and cross a river without loss, I knew was an arduous task, and seldom accomplished, if attempted. As our sentries were within 200 yards of other, I knew it would require the greatest care and attention. To cover my design from the enemy, I ordered a number of tents to be brought forward and pitched in sight of the enemy, and almost the whole army employed themselves in fortifying the camp. The heavy baggage and stores were falling back and crossing through the day; at dark, the tents were struck, the light baggage and troops passed dawn, and before twelve o’clock the main army had crossed with the stores and baggage. The Marquis de la Fayette arrived about 11 in the evening from Boston, where he had been by request of the general officers, to solicit the speedy return of the fleet. He was sensibly mortified that he was out of action; and that he might not be out of the way in case of action, he had rode from hence to Boston in seven hours , and returned in six and a half, the distance near seventy miles — he returned time enough to bring off the pickets, and other parties, which converted the retreat of the army, which he did in excellent order; not a man was left behind, nor the smallest article left. I hope my conduct through this expedition may merit the approbation of Congress. Major Morris, on of my aids will have the honor of delivering this to your Excellency; I must beg leave to recommend him to Congress as an officer who is in the last, as well as several other actions, has behaved with great spirit and good conduct, and doubt not Congress will take such notice of him, as his long service and spirited conduct deserves. I have the honor to be, dear Sir, with must___Your very humble servant – John Sullivan.”
