This proposition was answered by a demand that the whole army should ground their arms in their encampment, and surrender themselves prisoners of war. This demand was instantly rejected, with a declaration that if General Gates designed to insist on it, the negotiation must immediately break off, and hostilities recommence. On receiving this decided answer, Gates receded from the rigorous terms at first proposed; and a convention was signed, in which it was agreed that the British army, after marching out of their encampment with all the honours of war, should lay down their arms, and not serve against the United States till exchanged. They were not to be detained in captivity, but to be permitted to embark for England.
The situation of the armies considered,[91] these terms were highly honourable to the British general, and favourable to his nation. They were probably more advantageous than would have been granted by General Gates, had he entertained no apprehension from Sir Henry Clinton, who was, at length, making the promised diversion on the North River, up which he had penetrated as far as Æsopus.
The drafts made from Peekskill for both armies had left that post in a situation to require the aid of militia for its security. The requisitions of General Putnam were complied with; but the attack upon them being delayed, the militia, who were anxious to seed their farms, became impatient; many deserted; and General Putnam was induced to discharge the residue.
Governor Clinton immediately ordered out half the militia of New York, with assurances that they should be relieved in one month by the other half. This order was executed so slowly that the forts were carried before the militia were in the field.
Great pains had been taken, and much labour employed, to render this position, which is naturally strong, still more secure. The principal defences were forts Montgomery and Clinton. They had been constructed on the western bank of the Hudson, on very high ground, extremely difficult of access, and were separated from each other by a small creek which runs from the mountains into the river. These forts were too much elevated to be battered from the water, and the hills on which they stood were too steep to be ascended by troops landing at the foot of them. The mountains, which commence five or six miles below them, are so high and rugged, the defiles, through which the roads leading to them pass, so narrow, and so commanded by the heights on both sides, that the approaches to them are extremely difficult and dangerous.
To prevent ships from passing the forts, chevaux-de-frise had been sunk in the river, and a boom extended from bank to bank, which was covered with immense chains stretched at some distance in its front. These works were defended by the guns of the forts, and by a frigate and galleys stationed above them, capable of opposing with an equal fire in front any force which might attack them by water from below.
Fort Independence is four or five miles below forts Montgomery and Clinton, and on the opposite side of the river, on a high point of land; and fort Constitution is rather more than six miles above them, on an island near the eastern shore. Peekskill, the general head quarters of the officer commanding at the station, is just below fort Independence, and on the same side of the river. The garrisons had been reduced to about six hundred men; and the whole force under General Putnam did not much exceed two thousand. Yet this force, though far inferior to that which General Washington had ordered to be retained at the station, was, if properly applied, more than competent to the defence of the forts against any numbers which could be spared from New York. To insure success to the enterprise, it was necessary to draw the attention of Putnam from the real object, and to storm the works before the garrisons could be aided by his army. This Sir Henry Clinton accomplished.
October 6.
Between three and four thousand men embarked at New York, and landed on the 5th of October at Verplank's Point, on the east side of the Hudson, a short distance below Peekskill, upon which General Putnam retired to the heights in his rear. On the evening of the same day, a part of these troops re-embarked, and the fleet moved up the river to Peekskill Neck, in order to mask King's ferry, which was below them. The next morning, at break of day, the troops destined for the enterprise, landed on the west side of Stony Point, and commenced their march through the mountains, into the rear of forts Clinton and Montgomery.[92] This disembarkation was observed; but the morning was so foggy that the numbers could not be distinguished; and a large fire, which was afterwards perceived at the landing place, suggested the idea that the sole object of the party on shore was the burning of some store houses. In the mean time, the manoeuvres of the vessels, and the appearance of a small detachment left at Verplank's Point, persuaded General Putnam that the meditated attack was on fort Independence.
