So soon as Washington heard the enemy's cannonade he rode with all speed to the front, and used every exertion to rally the runaways; but his efforts, though seconded by the officers in immediate command, were utterly futile. Mortified and in despair at such poltroonery, the commander-in-chief almost lost control of himself, and, says General Greene, "sought death rather than life" at the hands of the enemy. 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." [Illustration: 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.

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.
