A treaty was opened with a general proposition stating the willingness of the British general to spare the further effusion of blood, provided a negotiation could be effected on honorable terms. 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 (October 17, 1777), in which it was agreed that the British army, after marching out of their encampment with all the honors 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, [9] these terms were highly honorable to the British general and favorable to his nation. They were probably more advantageous than would have been granted by 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 Aesopus. 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 attend to their farms, became impatient; many deserted, and 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 labor employed to render the position of the American army for guarding the passage up the Hudson secure. The principal defenses 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.
