On the night of Monday (Sept. 2d) a forty gun ship, taking advantage of a favorable wind and tide, passed between Governor's Island and Long Island, swept unharmed by the batteries which opened upon her, and anchored in Turtle Bay, above the city. In the morning, Washington despatched Major Crane of the artillery, with two twelve pounders and a howitzer to annoy her from the New York shore. They hulled her several times, and obliged her to take shelter behind Blackwell's Island. Several other ships-of-war, with transports and store-ships had made their appearance in the upper part of the Sound, having gone round Long Island.
As the city might speedily be attacked, Washington caused all the sick and wounded to be conveyed to Orangetown, in the Jerseys, and such military stores and baggage as were not immediately needed, to be removed, as fast as conveyances could be procured, to a post partially fortified at Dobbs' Ferry, on the eastern bank of the Hudson, about twenty-two miles above the city.
The thousand men ordered from the flying camp were furnished by General Mercer. They were Maryland troops under Colonels Griffith and Richardson, and were a seasonable addition to the effective forces; but the ammunition carried off by the disbanding militia was a serious loss at this critical juncture.
A work had been commenced on the Jersey shore, opposite Fort Washington, to aid in protecting Putnam's chevaux-de-frise which had sunk between them. This work had received the name of Fort Constitution (a name already borne by one of the forts in the Highlands). Troops were drawn from the flying camp to make a strong encampment in the vicinity of the fort, with an able officer to command it and a skilful engineer to strengthen the works. It was hoped, by the co-operation of these opposite forts and the chevaux-de-frise, to command the Hudson, and prevent the passing and repassing of hostile ships.
The British, in the meantime, forbore to press further hostilities. Lord Howe was really desirous of a peaceful adjustment of the strife between the colonies and the mother country, and supposed this a propitious moment for a new attempt at pacification. He accordingly sent off General Sullivan on parole, charged with an overture to Congress. In this he declared himself empowered and disposed to compromise the dispute between Great Britain and America, on the most favorable terms, and though he could not treat with Congress as a legally organized body, he was desirous of a conference with some of its members. These, for the time, he should consider only as private gentlemen, but if in the conference any probable scheme of accommodation should be agreed upon, the authority of Congress would afterwards be acknowledged to render the compact complete.
The message caused some embarrassment in Congress. To accede to the interview might seem to waive the question of independence; to decline it was to shut the door on all hope of conciliation, and might alienate the co-operation of some worthy whigs who still clung to that hope. After much debate, Congress, on the 5th September, replied that, being the representatives of the free and independent States of America, they could not send any members to confer with his lordship in their private characters, but that, ever desirous of establishing peace on reasonable terms, they would send a committee of their body to ascertain what authority he had to treat with persons authorized by Congress, and what propositions he had to offer. A committee was chosen on the 6th of September, composed of John Adams, Edward Rutledge, and Doctor Franklin.
The proposed conference was to take place on the 11th, at a house on Staten Island, opposite to Amboy; at which latter place the veteran Mercer was stationed with his flying camp. At Amboy, the committee found Lord Howe's barge waiting to receive them. The admiral met them on their landing, and conducted them through his guards to his house.
On opening the conference, his lordship again intimated that he could not treat with them as a committee of Congress, but only confer with them as private gentlemen of influence in the colonies, on the means of restoring peace between the two countries. The commissioners replied that as their business was to hear, he might consider them in what light he pleased; but that they should consider themselves in no other character than that in which they were placed by order of Congress. Lord Howe then entered into a discourse of considerable length, but made no explicit proposition of peace, nor promise of redress of grievances, excepting on condition that the colonies should return to their allegiance. This, the commissioners replied, was not now to be expected. Their repeated humble petitions to the king and parliament having been treated with contempt, and answered by additional injuries, and war having been declared against them, the colonies had declared their independence, and it was not in the power of Congress to agree for them that they should return to their former dependent state. His lordship expressed his sorrow that no accommodation was likely to take place; and the conference broke up.
The result of this conference had a beneficial effect. It showed that his lordship had no power but what was given by the act of Parliament; and put an end to the popular notion that he was vested with secret powers to negotiate an adjustment of grievances.
Since the retreat from Brooklyn, Washington had narrowly watched the movements of the enemy to discover their further plans. Their whole force, excepting about four thousand men, had been transferred from Staten to Long Island. A great part was encamped on the peninsula between Newtown Inlet and Flushing Bay. A battery had been thrown up near the extremity of the peninsula, to check an American battery at Horen's Hook opposite, and to command the mouth of Harlem River. Troops were subsequently stationed on the islands about Hell Gate. "It is evident," writes Washington, "the enemy mean to enclose us on the island of New York, by taking post in our rear, while the shipping secures the front, and thus, by cutting off our communication with the country, oblige us to fight them on their own terms, or surrender at discretion."
The question was, how could their plans be most successfully opposed? On every side, he saw a choice of difficulties; every measure was to be formed with some apprehension that all the troops would not do their duty. In a council of war, held on the 7th of September, the question was discussed, whether the city should be defended or evacuated. All admitted that it would not be tenable, should it be cannonaded and bombarded. Several of the council, among whom was General Putnam, were for a total and immediate removal from the city; urging that one part of the army might be cut off before the other could support it; the extremities being at least sixteen miles apart, and the whole, when collected, being inferior to the enemy. By removing, they would deprive the enemy of the advantage of their ships; they would keep them at bay; put nothing at hazard; keep the army together to be recruited another year, and preserve the unspent stores and the heavy artillery. Washington himself inclined to this opinion. Others, however, were unwilling to abandon a place which had been fortified with great cost and labor, and seemed defensible, and which, by some, had been considered the key to the northern country.
After much discussion a middle course was adopted. Putnam, with five thousand men, was to be stationed in the city. Heath, with nine thousand, was to keep guard on the upper part of the Island, and oppose any attempt of the enemy to land. His troops, among whom were Magaw's, Shee's, Hand's, and Miles's Pennsylvanian battalions, and Haslet's Delaware regiment, were posted about King's Bridge and its vicinity.
The third division, composed principally of militia, was under the command of Generals Greene and Spencer, the former of whom, however, was still unwell. It was stationed about the centre of the island,
