On the invasion of Connecticut, the Commander-in-chief was prompt in his exertions to send continental troops from the nearest encampments to its aid; but, before they could afford any real service, Sir Henry Clinton found it necessary to recall Tryon to the Hudson.

General Washington had planned an enterprise against the posts at King's Ferry, comprehending a double attack, to be made at the same time, on both. But the difficulty of a perfect co-operation of detachments, incapable of communicating with each other, determined him to postpone the attack on Verplank's, and to make that part of the plan dependent on the success of the first. His whole attention therefore was turned to Stony Point; and the troops destined for this critical service, proceeded on it as against a single object.

The execution of the plan was entrusted to General Wayne, who commanded the light infantry of the army. Secrecy was deemed so much more essential to success than numbers, that no addition was made to the force already on the lines. One brigade was ordered to commence its march, so as to reach the scene of action in time to cover the troops engaged in the attack, should any unlooked-for disaster befall them; and Major Lee of the light dragoons, who had been eminently useful in obtaining the intelligence which led to the enterprise, was associated with General Wayne, as far as cavalry could be employed in such a service. July.The night of the fifteenth, and the hour of twelve, were chosen for the assault.

Stony Point is a commanding hill, projecting far into the Hudson, which washes three-fourths of its base. The remaining fourth is, in a great measure, covered by a deep marsh, commencing near the river on the upper side, and continuing into it below. Over this marsh there is only one crossing place; but at its junction with the river, is a sandy beach, passable at low tide. On the summit of this hill stood the fort, which was furnished with heavy ordnance. Several breast-works and strong batteries were advanced in front of the main work; and, about half way down the hill, were two rows of abattis. The batteries were calculated to command the beach and the crossing place of the marsh, and to rake and enfilade any column which might be advancing from either of those points towards the fort. In addition to these defences, several vessels of war were stationed in the river, and commanded the ground at the foot of the hill. The garrison consisted of about six hundred men, commanded by Colonel Johnson.

General Wayne arrived about eight in the afternoon at Spring Steel's, one and a half miles from the fort; and made his dispositions for the assault.

It was intended to attack the works on the right and left flanks at the same instant. The regiments of Febiger and of Meigs, with Major Hull's detachment, formed the right column; and Butler's regiment, with two companies under Major Murfree, formed the left. One hundred and fifty volunteers, led by Lieutenant Colonel Fleury and Major Posey, constituted the van of the right; and one hundred volunteers under Major Stewart, composed the van of the left. At half past eleven the two columns moved to the assault, the van of each with unloaded muskets, and fixed bayonets. They were each preceded by a forlorn hope of twenty men, the one commanded by Lieutenant Gibbon, and the other by Lieutenant Knox. General Wayne surprises and takes Stony Point.They reached the marsh undiscovered; and, at twenty minutes after twelve, commenced the assault.

Both columns rushed forward under a tremendous fire. Surmounting every obstacle, they entered the works at the point of the bayonet; and, without discharging a single musket, obtained possession of the fort.

The humanity displayed by the conquerors was not less conspicuous, nor less honourable than their courage. Not an individual suffered after resistance had ceased.

All the troops engaged in this perilous service manifested a degree of ardour and impetuosity, which proved them to be capable of the most difficult enterprises; and all distinguished themselves, whose situation enabled them to do so. Colonel Fleury was the first to enter the fort and strike the British standard. Major Posey mounted the works almost at the same instant, and was the first to give the watch word—"The fort's our own."—Lieutenants Gibbon and Knox performed the service allotted to them with a degree of intrepidity which could not be surpassed. Of twenty men who constituted the party of the former, seventeen were killed or wounded.

Sixty-three of the garrison were killed, including two officers. The prisoners amounted to five hundred and forty-three, among whom were one lieutenant colonel, four captains, and twenty subaltern officers. The military stores taken in the fort were considerable.[18]
