THE BATTLE-FIELD.--Recently gathered material seems to settle all doubts as to the several points occupied by the British and Americans during the action. Where did it begin and where did it end? As to the first skirmish, it began near the British encampment at Bloomingdale. Here was Howe's left, and, as Howe reports, Knowlton approached his advanced posts under cover of the woods "by way of Vandewater's Height." This was what we call Bloomingdale Heights. The original proprietor of the greater part of this site was Thomas De Key. From him all or a large part of it passed to Harman Vandewater and Adrian Hogeland, as the deeds on record show. In 1784 the property was purchased by Nicholas De Peyster. The position of Hogeland's and Vandewater's houses as given on the accompanying map is taken from old surveys which mark the location and give the names. The Bloomingdale Road at that time stopped at these farms. That part of it above One Hundred and Tenth Street, running through Manhattanville and continuing until recently to the King's Bridge Road at One Hundred and Forty-sixth Street, did not exist during the Revolution, but was opened a few years later. (Hoffman's _Est. and Rights of the Corporation of New York_, vol. ii.) A lane or road running from Hogeland's by Vandewater's connected the Bloomingdale with the King's Bridge road at One Hundred and Nineteenth Street. Washington himself gives us the general line. Before the battle of Long Island he ordered Heath to have troops ready to march to New York as soon as called for, and he describes the proper route thus: "There is a road out of the Haerlem flat lands that leads up to the hills, and continues down the North River by Bloomingdale, Delancy's, &c., which road I would have them march, as they will keep the river in sight, and pass a tolerable landing-place for troops in the neighborhood of Bloomingdale." (_Heath Correspondence_, Mass. Hist. Coll. for 1878.) From this topography and the records the position becomes clear: Howe camped around Bloomingdale with his advance posts along the Bloomingdale Road, perhaps as far as its terminus near Hogeland's. They were last seen in this vicinity the night before. Knowlton, next morning, marches out from Harlem Heights, reconnoitres "by way of Vandewater's," and comes upon the British posts on and along the line of the Bloomingdale Road. Then he falls back under cover of the woods and over fences towards the Point of Rocks, the enemy following him.
