The Battle of Stony Point took place on July 16, 1779, during the American Revolutionary War. In a well-planned and -executed nighttime attack, a highly trained select group of George Washington's Continental Army troops under the command of Brigadier General "Mad Anthony" Wayne defeated British troops in a quick and daring assault on their outpost in Stony Point, New York, located in present day Rockland County, approximately 30 mi (48 km) north of New York City.
The British suffered heavy losses in a battle that served as an important victory in terms of morale for the Continental Army. While the fort was ordered evacuated quickly after the battle by General Washington, this key crossing site was used later in the war by units of the Continental Army to cross the Hudson River during the final stages of the war.
Background
Following the surrender of General John Burgoyne after the Battles of Saratoga in October 1777 and the subsequent entry of France into the war as an American ally, British strategy in dealing with the rebellious Americans was forced to change. In the northern states, their strategy was reduced to raids against targets of economic and military importance, and unsuccessful attempts to bring General George Washington's Continental Army into a decisive confrontation. Washington deployed his army in strong positions around the principal British base at New York City, and refused to be drawn out of them.
British military plans for 1779 were large in ambition, but were ultimately hampered, in the opinion of their North American commander in chief, Lieutenant General Sir Henry Clinton, by shortages of manpower, and delays in the arrival of manpower that was promised for the campaign. Clinton sought to force Washington to weaken the Continental Army camp at Middlebrook in northern New Jersey, after which he would march in force out of New York and capture it. This, Clinton believed, would threaten Washington's supply lines, drawing him out of the highlands on the Hudson River into more favorable terrain for a general engagement.
British dispositions
In late May 1779, General Clinton led a force of about 8,000 men up the North (or Hudson) River as the opening move in this strategy. The British strategists realized that the Stony Point location represented a vital area that controlled that portion of the Hudson River and the entrance to the Hudson Highlands, as well as the nearby Kings Ferry crossing. Because of this they decided to assault it. General Clinton, with approximately 6,000 British, Loyalist, and Hessian soldiers under his command sailed up the Hudson, transported by the Royal Navy and landed unopposed.
Stony Point was defended by a meager force totaling around 40 American Patriots, and before escaping to the north the small garrison set fire to the wooden blockhouse that was the unfinished fort built atop Stony Point. The British forces, in order to capture nearby Fort Lafayette, hauled several cannons up the steep and rugged slopes of Stony Point and used the vantage point to shell Fort Lafayette. This move effectively closed King's Ferry, a major river crossing at that narrow point in the river, about 10 miles (16 km) south of West Point and 35 miles (56 km) north of New York City.
While he waited for reinforcements to arrive so that he might march on Middlebrook, Clinton dispatched William Tryon and more than 2,000 troops on a raiding expedition in early July against coastal communities in Connecticut, claiming in retrospect that its purpose was to draw Washington's troops further east. Clinton reduced the garrisons at Stony Point and Verplanck's Point for the operation, which failed to draw Washington out of his camps.
Stony Point was garrisoned with elements of the 17th Regiment of Foot under the command of Lt. Col. Henry Johnson. The 17th was reinforced by a grenadier company belonging to one of the two battalions of the 71st Regiment, and a company-strength detachment of the Loyal American Regiment. A detachment of the Royal Artillery manned fifteen field pieces that included five iron and two brass cannon, four mortars and four small howitzers. A Royal Navy gunboat was assigned to protect the river approaches to the fortifications, and the armed sloop Vulture was also anchored in that part of the river.
Washington observed construction of the fortifications through a telescope from atop nearby Buckberg Mountain. Historians also believe he used intelligence gathered from local merchants to get a better idea of the strength of the garrison, the types of watchwords in use, and the placement of sentries – especially on the south side of the point, which could not be seen from Buckberg. During this time he formulated a plan of attack and selected a commander to lead it – Brigadier General Anthony Wayne, commander of the Pennsylvania Line.
The British position at Stony Point was a fortified one, but it was never intended to be a true fort in the 18th century European sense of the word. No stone was used and no walls were constructed. The defenses consisted of earthen fleches (cannon positions) and wooden abatis (felled trees sharpened to a point and placed in earthen embankments). The defenses were situated on a rocky elevation approachable only from the west, protected in the front by a watery defile and on both flanks by extensive swampy areas.
American forces and tactics
To storm the position, the Corps of Light Infantry was formed on June 12, with command assigned to General Wayne. The Corps of Light Infantry was an elite, seasonal combat organization drafted in each of the years between 1777 and 1781 from the light infantry companies of each regiment in Washington's army. The 1779 Corps was organized into a brigade of four regiments, each composed of two battalions of four companies, with the following order of battle:
The plan called for a night attack on the fortifications to be carried out by the 1,350 men of the corps. Each regiment consisted of 300 to 340 men, and the total force included an artillery detachment to man captured British field pieces. According to 18th century military doctrine, this was not enough men to take a well-prepared defensive position, but in addition to the element of surprise, Washington's plan exploited a fatal flaw in the fortifications.
The wooden abatis along the southern shore of the point were not extended into the deep water of the Hudson and could be outflanked by attackers along a narrow beach at low tide. The main attack would be along this approach, but Washington advised that if practicable, secondary and diversionary attacks could also be made along the north shore of the point and across the causeway to the center.
Washington gave Wayne his instructions, along with permission to modify the plan as necessary. This was an unusual act for Washington, and indicates the high opinion he had of Wayne's tactical abilities. The assault would be difficult: it would be carried out in the dead of night, called for the men to scale the steep, rocky sides of Stony Point, and required surprise. To accomplish this last element, Washington ordered that the men carry unloaded muskets and attack using only bayonets to maintain silence, a tactic often employed by the British army, and had been used to devastating effect against Wayne two years prior at Paoli.
The exception to loaded weaponry were the two companies of North Carolina light infantry, which Wayne ordered to cross the causeway, and stage a demonstration attack at the center of the British defenses, where the British expected an attack to come. This battalion, commanded by Maj. Hardy Murfree, was instructed to lay down a "gauling fire" with their weapons as a diversionary tactic.
Wayne selected Butler's 2nd Regiment of approximately 300 men to conduct an assault along the northern shore of the point, while Wayne himself would lead the main column in the south, consisting of the 1st and 3rd Regiments, and Hull's detachment of Massachusetts light infantry. The columns deployed an advance force of 100 and 150 men respectively wielding axes to clear obstacles, with 20 men from each advance force assigned as the forlorn hopes, to protect the force and to be the first to enter the works. Wayne announced that he would give prize bounties to the first men who entered the works, and to anyone else who distinguished himself in the action.
Battle
After a morning muster, on July 15, the Corps of Light Infantry marched from Sandy Beach north of Fort Montgomery beginning at noon. Any civilians met along the route of march were to be taken into custody to prevent them from warning the British. The column, often forced to march single file over rough terrain and roads hardly more than paths, took a circuitous route west through Queensboro to the west and over Dunderberg Mountain to avoid detection by the British. The Corps began arriving at 8 p.m. at the Springsteel farm, a mile and a half (2 km) west of the fortifications, and by 10 p.m. had been formed in the attack columns.
The men were given a rum ration and their orders. They were also given pieces of white paper to pin to their hats in order to help them tell each other from the British in the darkness. The columns then moved out at 11:30 p.m. to their jump-off points, diverging immediately, to begin the assault at midnight. These attack columns were led by groups of volunteer soldiers nicknamed the "forlorn hope" who were responsible for breaking holes in enemy defenses and along with their weapons, were armed with axes and picks.
Bad weather that night aided the Continentals. Cloud cover cut off moonlight and high winds forced the British ships in Haverstraw Bay to leave their posts off Stony Point and move downriver. At midnight, as scheduled, the attack began with the columns crossing the swampy flanks of the point. The southern column unexpectedly found its approach inundated in two to four feet of water and required thirty minutes to wade to the first line of abatis, during which it and Murfree's demonstration force were spotted by British sentries and fired upon.
Under fire Wayne's column succeeded in getting inside the British first line of defenses. Wayne himself was struck in the head by a spent musket ball and fell to the ground, leaving Col. Febiger to take over command of Wayne's column. Meanwhile, Butler's column had succeeded in cutting its way through the abatis, sustaining the only loss of life on the American side while doing so. The two columns penetrated the British line almost simultaneously and seized the summit when six companies of the 17th Regiment of Foot took positions opposite the diversionary attack and were cut off.
Because of the stealth in which the Patriot assault forces approached the British defenses on the slopes of the hill, the artillery pieces that the British had placed on the summit for just such defensive purposes were unsuccessful in repelling the attack. Due to the speed at which the Patriot infantrymen were moving, the British cannons could not be lowered to an angle low enough to sufficiently harass the men assaulting up the hill.
The first man into the British upper works was Lt. Col. Francois de Fleury, an aristocrat French engineer commanding a battalion of the 1st Regiment. He was followed by Lt. Henry Knox, Sgt. William Baker, Sgt William Spencer and Sgt. George Donlop. As the men entered the British works they called out, "The fort's our own!" – the prearranged watchword to distinguish friend from foe. The action lasted 25 minutes and was over by 1 a.m.
Wayne's losses were 15 killed and 83 wounded. 546 prisoners were taken, 74 of whom were wounded. Some Patriot sources stated that there were 63 British dead but military historian Mark M. Boatner accepts the official British report of 20 killed. However, the report (from Lt-Col. Johnson to Sir Henry Clinton on July 24) also lists 58 missing separate from killed, wounded, and captured, many of whom may have drowned in the Hudson.
