The defeat of the American army on Long Island, a heavy blow to the patriot cause, suggested a desperate remedy to the mind of Washington,—no less a measure than the deliberate destruction of the great commercial city of New York. "Till of late", he writes to the President of Congress, "I had no doubt in my own mind of defending this place; nor should I have yet if the men would do their duty, but this I despair of.... If we should be obliged to abandon the town, ought it to stand as winter-quarters for the enemy? They would derive great conveniences from it on the one hand, and much property would be destroyed on the other.... At present I dare say the enemy mean to preserve it if they can. If Congress, therefore, should resolve upon the destruction of it, the resolution should be a profound secret, as the knowledge of it will make a capital change in their plans." General Greene, John Jay, and many others of note were of the same opinion. Congress decided otherwise, and Howe forbore to bombard it from Brooklyn Heights and Governor's Island, both belligerents deeming its possession of far greater service to either than its destruction. As New York was not to be destroyed, it became a serious question how a city swarming with Tories was to be defended with less than twenty thousand militia against a powerful army. Washington, Greene, Putnam, and others were opposed to the attempt, but were overruled by a council of war. The question was finally left by Congress to the commander-in-chief, who, deeming the city untenable, made preparations, September 10th, for its speedy evacuation, which was concurred in, two days later, by a new council of war. This determination was timely, as the Americans were about to be driven out. Howe, anticipating Washington's design, determined to prevent the execution of it by the same manœuvre he had tried so successfully on Long Island,—that was to threaten the city's front and right flank by the fleet, while his army, assembled about the present site of Astoria, should cross the East River, turn Washington's left flank, cut off his communications with the mainland, oblige him to fight on the enemy's terms, and force him to surrender at discretion, or by a brilliant stroke break the American army in pieces, and secure their arms and stores. On the evening of September 14th Howe began his crossing of the East River by taking possession of Montressor (Randall's) Island, and the next morning he sent three ships up the Hudson as high as Bloomingdale, which stopped any further evacuation of the city by water. Soon after, under the fire of ten vessels-of-war, the main British force, under Sir Henry Clinton, embarked upon flatboats, barges, and galleys, at the mouth of Newtown Creek, and by the favoring tide was carried to Kip's Bay (34th Street), where they disembarked and quickly put to rout the panic-stricken American militia, and pursued the fugitives in disorderly flight over the fields to Murray Hill.
