Soon after his arrival, Lieutenant Colonel Knowlton of Connecticut, who, at the head of a corps of rangers, had been skirmishing with this party, came in, and stated their numbers on conjecture at about three hundred men; the main body being concealed in a wood.
The General ordered Colonel Knowlton with his rangers, and Major Leitch with three companies of the third Virginia regiment, which had joined the army only the preceding day, to gain their rear, while he amused them with the appearance of making dispositions to attack their front.
[Sidenote: Skirmish on the heights of Haerlem.] This plan succeeded.

The British ran eagerly down a hill, in order to possess themselves of some fences and bushes, which presented an advantageous position against the party expected in front; and a firing commenced--but at too great a distance to do any execution.

In the mean time, Colonel Knowlton, not being precisely acquainted with their new position, made his attack rather on their flank than rear; and a warm action ensued.
In a short time, Major Leitch, who had led the detachment with great intrepidity, was brought off the ground mortally wounded, having received three balls through his body; and soon afterwards the gallant Colonel Knowlton also fell.

Not discouraged by the loss of their field officers, the captains maintained their ground, and continued the action with great animation.

The British were reinforced; and General Washington ordered some detachments from the adjacent regiments of New England and Maryland, to the support of the Americans.
