In such a situation even the best skill of Washington was likely only to qualify defeat. He was advised to destroy New York and retire to positions more tenable. But even if he had so desired, Congress, his master, would not permit him to burn the city, and he had to make plans to defend it. Brooklyn Heights so commanded New York that enemy cannon planted there would make the city untenable. Accordingly Washington placed half his force on Long Island to defend Brooklyn Heights and in doing so made the fundamental error of cutting his army in two and dividing it by an arm of the sea in presence of overwhelming hostile naval power.
On the 22d of August Howe ferried fifteen thousand men across the Narrows to Long Island, in order to attack the position on Brooklyn Heights from the rear. Before him lay wooded hills across which led three roads converging at Brooklyn Heights beyond the hills. On the east a fourth road led round the hills. In the dark of the night of the 26th of August Howe set his army in motion on all these roads, in order by daybreak to come to close quarters with the Americans and drive them back to the Heights. The movement succeeded perfectly. The British made terrible use of the bayonet. By the evening of the twenty-seventh the Americans, who fought well against overwhelming odds, had lost nearly two thousand men in casualties and prisoners, six field pieces, and twenty-six heavy guns. The two chief commanders, Sullivan and Stirling, were among the prisoners, and what was left of the army had been driven back to Brooklyn Heights. Howe's critics said that had he pressed the attack further he could have made certain the capture of the whole American force on Long Island.
Criticism of what might have been is easy and usually futile. It might be said of Washington, too, that he should not have kept an army so far in front of his lines behind Brooklyn Heights facing a superior enemy, and with, for a part of it, retreat possible only by a single causeway across a marsh three miles long. When he realized, on the 28th of August, what Howe had achieved, he increased the defenders of Brooklyn Heights to ten thousand men, more than half his army. This was another cardinal error. British ships were near and but for unfavorable winds might have sailed up to Brooklyn. Washington hoped and prayed that Howe would try to carry Brooklyn Heights by assault. Then there would have been at least slaughter on the scale of Bunker Hill. But Howe had learned caution. He made no reckless attack, and soon Washington found that he must move away or face the danger of losing every man on Long Island.
On the night of the 29th of August there was clear moonlight, with fog towards daybreak. A British army of twenty-five thousand men was only some six hundred yards from the American lines. A few miles from the shore lay at anchor a great British fleet with, it is to be presumed, its patrols on the alert. Yet, during that night, ten thousand American troops were marched down to boats on the strand at Brooklyn and, with all their stores, were carried across a mile of water to New York. There must have been the splash of oars and the grating of keels, orders given in tones above a whisper, the complex sounds of moving bodies of men. It was all done under the eye of Washington. We can picture that tall figure moving about on the strand at Brooklyn, which he was the last to leave. Not a sound disturbed the slumbers of the British. An army in retreat does not easily defend itself. Boats from the British fleet might have brought panic to the Americans in the darkness and the British army should at least have known that they were gone. By seven in the morning the ten thousand American soldiers were for the time safe in New York, and we may suppose that the two Howes were asking eager questions and wondering how it had all happened.
Washington had shown that he knew when and how to retire. Long Island was his first battle and he had lost. Now retreat was his first great tactical achievement. He could not stay in New York and so sent at once the chief part of the army, withdrawn from Brooklyn, to the line of the Harlem River at the north end of the island. He realized that his shore batteries could not keep the British fleet from sailing up both the East and the Hudson Rivers and from landing a force on Manhattan Island almost where it liked. Then the city of New York would be surrounded by a hostile fleet and a hostile army. The Howes could have performed this maneuver as soon as they had a favorable wind. There was, we know, great confusion in New York, and Washington tells us how his heart was torn by the distress of the inhabitants. The British gave him plenty of time to make plans, and for a reason. We have seen that Lord Howe was not only an admiral to make war but also an envoy to make peace. The British victory on Long Island might, he thought, make Congress more willing to negotiate. So now he sent to Philadelphia the captured American General Sullivan, with the request that some members of Congress might confer privately on the prospects for peace.
Howe probably did not realize that the Americans had the British quality of becoming more resolute by temporary reverses. By this time, too, suspicion of every movement on the part of Great Britain had become a mania. Every one in Congress seems to have thought that Howe was planning treachery. John Adams, excepted by name from British offers of pardon, called Sullivan a “decoy duck” and, as he confessed, laughed, scolded, and grieved at any negotiation. The wish to talk privately with members of Congress was called an insulting way of avoiding recognition of that body. In spite of this, even the stalwart Adams and the suave Franklin were willing to be members of a committee which went to meet Lord Howe. With great sorrow Howe now realized that he had no power to grant what Congress insisted upon, the recognition of independence, as a preliminary to negotiation. There was nothing for it but war.
On the 15th of September the British struck the blow too long delayed had war been their only interest. New York had to sit nearly helpless while great men-of-war passed up both the Hudson and the East River with guns sweeping the shores of Manhattan Island. At the same time General Howe sent over in boats from Long Island to the landing at Kip's Bay, near the line of the present Thirty-fourth Street, an army to cut off the city from the northern part of the island. Washington marched in person with two New England regiments to dispute the landing and give him time for evacuation. To his rage panic seized his men and they turned and fled, leaving him almost alone not a hundred yards from the enemy. A stray shot at that moment might have influenced greatly modern history, for, as events were soon to show, Washington was the mainstay of the American cause. He too had to get away and Howe's force landed easily enough.
Meanwhile, on the west shore of the island, there was an animated scene. The roads were crowded with refugees fleeing northward from New York. These civilians Howe had no reason to stop, but there marched, too, out of New York four thousand men, under Israel Putnam, who got safely away northward. Only leisurely did Howe extend his line across the island so as to cut off the city. The story, not more trustworthy than many other legends of war, is that Mrs. Murray, living in a country house near what now is Murray Hill, invited the General to luncheon, and that to enjoy this pleasure he ordered a halt for his whole force. Generals sometimes do foolish things but it is not easy to call up a picture of Howe, in the midst of a busy movement of troops, receiving the lady's invitation, accepting it, and ordering the whole army to halt while he lingered over the luncheon table. There is no doubt that his mind was still divided between making war and making peace. Probably Putnam had already got away his men, and there was no purpose in stopping the refugees in that flight from New York which so aroused the pity of Washington. As it was Howe took sixty-seven guns. By accident, or, it is said, by design of the Americans themselves, New York soon took fire and one-third of the little city was burned.
After the fall of New York there followed a complex campaign. The resourceful Washington was now, during his first days of active warfare, pitting himself against one of the most experienced of British generals. Fleet and army were acting together. The aim of Howe was to get control of the Hudson and to meet half way the advance from Canada by way of Lake Champlain which Carleton was leading. On the 12th of October, when autumn winds were already making the nights cold, Howe moved. He did not attack Washington who lay in strength at the Harlem. That would have been to play Washington's game. Instead he put the part of his army still on Long Island in ships which then sailed through the dangerous currents of Hell Gate and landed at Throg's Neck, a peninsula on the sound across from Long Island. Washington parried this movement by so guarding the narrow neck of the peninsula leading to the mainland that the cautious Howe shrank from a frontal attack across a marsh. After a delay of six days, he again embarked his army, landed a few miles above Throg's Neck in the hope of cutting off Washington from retreat northward, only to find Washington still north of him at White Plains. A sharp skirmish followed in which Howe lost over two hundred men and Washington only one hundred and forty. Washington, masterly in retreat, then withdrew still farther north among hills difficult of attack.
Howe had a plan which made a direct attack on Washington unnecessary. He turned southward and occupied the east shore of the Hudson River. On the 16th of November took place the worst disaster which had yet befallen American arms. Fort Washington, lying just south of the Harlem, was the only point still held on Manhattan Island by the Americans. In modern war it has become clear that fortresses supposedly strong may be only traps for their defenders. Fort Washington stood on the east bank of the Hudson opposite Fort Lee, on the west bank. These forts could not fulfil the purpose for which they were intended, of stopping British ships. Washington saw that the two forts should be abandoned. But the civilians in Congress, who, it must be remembered, named the generals and had final authority in directing the war, were reluctant to accept the loss involved in abandoning the forts and gave orders that every effort should be made to hold them. Greene, on the whole Washington's best general, was in command of the two positions and was left to use his own judgment. On the 15th of November, by a sudden and rapid march across the island, Howe appeared before Fort Washington and summoned it to surrender on pain of the rigors of war, which meant putting the garrison to the sword should he have to take the place by storm. The answer was a defiance; and on the next day Howe attacked in overwhelming force. There was severe fighting. The casualties of the British were nearly five hundred, but they took the huge fort with its three thousand defenders and a great quantity of munitions of war. Howe's threat was not carried out. There was no massacre.
