Between three and four thousand men embarked at New York, and landed on the 5th of October at Verplank's Point, on the east side of the Hudson, a short distance below Peekskill, upon which General Putnam retired to the heights in his rear. On the evening of the same day, a part of these troops re-embarked, and the fleet moved up the river to Peekskill Neck, in order to mask King's ferry, which was below them. The next morning, at break of day, the troops destined for the enterprise, landed on the west side of Stony Point, and commenced their march through the mountains, into the rear of forts Clinton and Montgomery.[92] This disembarkation was observed; but the morning was so foggy that the numbers could not be distinguished; and a large fire, which was afterwards perceived at the landing place, suggested the idea that the sole object of the party on shore was the burning of some store houses. In the mean time, the manoeuvres of the vessels, and the appearance of a small detachment left at Verplank's Point, persuaded General Putnam that the meditated attack was on fort Independence. [Footnote 92: Letter of Sir Henry Clinton.] [Sidenote: Forts Montgomery and Clinton taken by the British.] His whole attention was directed to this object; and the real designs of the enemy were not suspected, until a heavy firing from the other side of the river announced the assault on forts Clinton and Montgomery. Five hundred men were instantly detached to reinforce the garrisons of those places; but before this detachment could cross the river the forts were in possession of the British. Having left a battalion at the pass of Thunderhill, to keep up a communication, Sir Henry Clinton had formed his army into two divisions; one of which consisting of nine hundred men, commanded by Lieutenant Colonel Campbell, made a circuit by the forest of Deane, in order to fall on the back of fort Montgomery; while the other, consisting of twelve hundred men, commanded by General Vaughan, and accompanied by Sir Henry Clinton in person, advanced slowly against fort Clinton.[93] [Footnote 93: Letter of Sir Henry Clinton.]
