Unopposed, the British marched to the Incleberg on Murray Hill and encamped, while the Americans retreated to Harlem Heights. Putnam, at the sacrifice of baggage and stores, and of most of his heavy artillery, by taking the river road, barely escaped with the troops remaining in the city. Howe was in close pursuit of this rear-guard of about four thousand men, but unexpectedly stopped for nearly two hours at the residence of Mrs. Murray[721] to enjoy her old Madeira, so that, in the language of the times, "Mrs. Murray saved the American army."
WASHINGTON'S HEADQUARTERS AT HARLEM
(Sept., 1776)
This was the house of Col. Roger Morris, and at a later day the residence of Madam Jumel. It follows a drawing in Valentine's N. Y. City Manual, 1854, p. 362. Cf. Lossing's Field-Book, ii. 816; Gay's Pop. Hist. U. S., iii. 505; and for a view of the hall, Harper's Magazine, lii. 640. Its position was east of Tenth Avenue, near One Hundred and Sixtieth Street.—Ed.
The British, on September 15, 1776, took possession of New York with a large detachment under General Robertson; while Howe with the main body of the army encamped on the outskirts of the city. The northern line of their camp extended from Horen's Hook on the East River to Bloomingdale on the Hudson, which line was fortified with field-works and protected on the flanks by vessels-of-war. Behind this line lay their disciplined army of twenty-five thousand British and Germans.
Washington took position in their front, and for the protection of his army of about fourteen thousand fit for duty he fortified Harlem Heights with a triple line of intrenchments extending across Manhattan Island. Immediately after securing his position, Washington, to arouse some military ardor in his discomfited militia, formed the design of cutting off some of the enemy's light troops, who, encouraged by their recent successes, had advanced to the extremity of the high ground opposite to the American camp. To effect this object, Colonel Knowlton, of Bunker Hill fame, and Major Leitch were detached with parties of rangers and riflemen to get in their rear, while Washington diverted their attention by a feigned direct attack. By some mistake, the fire was begun on the front instead of upon their flank and rear, by which the enemy, though defeated, secured their escape to their main body. This successful skirmish, called the battle of Harlem Plains, was purchased by the loss of the brave Knowlton and Leitch, both of whom were mortally wounded.
The British rejoicings upon the occupation of their snug winter-quarters in New York were suddenly interrupted, early on the morning of September 21st, by the breaking out of flames from a low groggery near Whitehall Slip, which, for want of proper fire apparatus to check them, spread rapidly over one fourth of the city, consuming five hundred buildings, including the Lutheran and Trinity churches. Whether this was the work of incendiaries is not positively known. Congress and the city's inhabitants had strenuously opposed such an act, though it was strongly recommended as a military necessity by Washington and by others of high rank and position.
While Howe "continued at gaze" awaiting coming events, Washington continued to strengthen his position on Harlem Heights, and established alarm posts on the east side of Harlem River as far as Throg's Neck on the Sound, to insure surveillance of the whole field of operations.
The Harlem lines being too strong for a front attack, Howe, after leaving a sufficient force under Lord Percy to watch them and guard the city, embarked, October 12th, his main army on ninety flatboats, to execute by his favorite manœuvre the turning of these obstacles and of Washington's left flank. His object was to cut off Washington's retreat and shut him up on Manhattan Island, the only exit from which was by Kingsbridge. Adverse winds so delayed the British general that he only passed Hell Gate on the afternoon of the 14th, and the fleet did not reach Throg's Neck till nightfall. Here Howe had previously landed his advance-guard, but Washington had anticipated him by occupying, on the 12th, the passes leading to the mainland.
The enemy's design being now fully developed, it was decided in a council of war, held in the American camp on the 16th, to leave Harlem Heights, no longer tenable, and to evacuate the whole of Manhattan Island except Fort Washington, which General Greene deemed impregnable and of great value for future operations. Accordingly, the American army formed a series of intrenched camps on the hills skirting the right bank of the swollen Bronx, and extending thirteen miles, from Fordham Heights to White Plains, and protected from the enemy by the river in front.
