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 cooperation of detachments, incapable of communicating with each other, determined him to postpone the attack on Verplanck'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 by Washington to General Wayne who commanded the light infantry of the army. His daring courage had long since obtained for him the sobriquet of "Mad Anthony." He accepted the command with alacrity. 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 Maj. Henry Lee of the light dragoons, who had been eminently useful in obtaining the intelligence which led to the enterprise, was associated with Wayne as far as cavalry could be employed in such a service. The night of the 15th (July, 1779), 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 was 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 was only one crossing place, but at its junction with the river was a sandy beach passable at low tide. On the summit of this hill stood the fort which was furnished with heavy ordnance. Several breastworks 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 toward the fort. In addition to these defenses several vessels of war were stationed in the river and commanded the ground at the foot of the hill. The garrison consisted of about 600 men commanded by Colonel Johnson.
Wayne arrived about eight in the evening at Springsteel'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 100 volunteers under Major Stewart composed the van of the left. At 11:30 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. They reached the marsh undiscovered and at 12:20 commenced the assault.
Both columns rushed forward under a tremendous fire of grape-shot and musketry. 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 honorable than their courage. Not an individual suffered after resistance had ceased.
All the troops engaged in this perilous service manifested a degree of ardor 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, who had distinguished himself in defense of the forts on the Delaware in 1777, 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. {1} Sixty-three of the garrison were killed, including two officers. The prisoners amounted to 543, among whom were 1 lieutenant-colonel, 4 captains, and 20 subaltern officers. The military stores taken in the fort were considerable.
The loss sustained by the assailants was not proportioned to the apparent danger of the enterprise. The killed and wounded did not exceed 100 men. Wayne, who marched with Febiger's regiment in the right column received a wound in the head which stunned him. Recovering consciousness, but believing the wound to be mortal, he said to his aids, "Carry me into the fort and let me die at the head of my column." Being supported by his aids he entered the fort with the regiment. Lieutenant-Colonel Hay was also among the wounded.
Although the design upon Fort Fayette had yielded to the desire of securing the success of the attack on Stony Point it had not been abandoned. Two brigades under General M'Dougal had been ordered to approach the works on Verplanck's, in which Colonel Webster commanded, and be in readiness to attack them the instant Wayne should obtain possession of Stony Point. That this detachment might not permit the favorable moment to pass unimproved Wayne had been requested to direct the messenger who should convey the intelligence of his success to Washington to pass through M'Dougal's camp and give him advice of that event. He was also requested to turn the cannon of the fort against Verplanck's and the vessels in the river. The last orders were executed and a heavy cannonade was opened on Fort Fayette and on the vessels, which compelled them to fall down the river. Through some misconception, never explained, the messenger dispatched by Wayne did not call on M'Dougal, but proceeded directly to headquarters. Thus, every advantage expected from the first impression made by the capture of Stony Point was lost, and the garrison had full leisure to recover from the surprise occasioned by that event and to prepare for an attack. This change of circumstances made it necessary to change the plan of operation. Washington ordered General Howe to take the command of M'Dougal's detachment to which some pieces of heavy artillery were to be annexed. He was directed, after effecting a breach in the walls, to make the dispositions for an assault and to demand a surrender, but not to attempt a storm until it should be dark. To these orders explicit instructions were added not to hazard his party by remaining before Verplanck's after the British should cross Croton river in force.
