Upon the extremity of the point is now " in course of erection by the United States government, a very strong fortification, called Fort Schuyler. It is calculated, when completed, to defend this entrance and protect the city of New York from foreign invasions, in connection with the formidable works of a similar character erected at the Narrows."^^

Throckmorton's point is distinguished as being the scene of important military operations, and was for a short time in the possession of ihe enemy during the revolutionary war. The following account is from General Heath's memoirs.

" October 3d, 1776. The brigadier generals of our general's division,'' were in council, and several new works were laid out ; among others, a redoubt on the hill above William's bridge. Our general, in reconnoitering his position, accompanied by Col. Hand, below the camp of the rifle corps, being apprehensive that the British might land on Frog's neck, took a view of the causeway between Westchester and the point. Upon the neck, which runs between these two, is a tide mill, and a plank bridge at the mill, at the west end of the causeway, (the side of the American army,) was at this time a range of cord wood, as advantageously situated to cover a party to defend the pass as if constructed for the very purpose. After taking a full view, our general directed Col. Hand, immediately on his return to his camp, to fix upon one of the best subaltern officers, and twenty-five picked men of his corps, and assign them to this pass, as their alarm-post at all times ; and in case the enemy made a landing on Frog's neck, to direct this officer immediately to take up the planks of the bridge ; to have everything in readiness to set the mill on fire; but not to do it, unless the fire of the riflemen should appear insufficient to check the advance of the enemy on the causeway; to assign another party to the head of the creek ; to reinforce both, in case the enemy landed ; and that he should be supported.
