The Battle of Forts Clinton and Montgomery was fought in the Hudson Highlands of the Hudson River valley on 6 October 1777, during the American Revolutionary War. British troops under General Sir Henry Clinton captured Fort Clinton and Fort Montgomery and dismantled the first iteration of the Hudson River Chains.
The purpose of the British attack was to create a diversion to draw American troops from the army of General Horatio Gates, which was opposing British General John Burgoyne's attempt to gain control of the Hudson. Both forts were garrisoned by about 600 Continental Army troops under the command of two brothers, General George Clinton and General James Clinton, while General Israel Putnam led additional troops at nearby Fort Independence in the vicinity of Peekskill, New York. Using a series of feints, Clinton fooled Putnam into withdrawing most of his troops to the east, and then he landed 2,100 troops on the west side of the Hudson to assault the two forts.
After several hours of hiking through the hilly terrain, Clinton divided his troops to stage simultaneous assaults on the two forts. Although the approach to Fort Montgomery was contested by a company armed with a small field piece, they attacked the two forts at nearly the same time and captured them after a relatively short battle. More than half the American defenders were killed, wounded, or captured. The British followed up this success with raids as far north as Kingston before being recalled to New York City. The action came too late to be of any assistance to Burgoyne, who surrendered his army on October 17. The only notable consequence of the action was the casualties suffered and the British destruction of the two forts on their departure.
Background
The Hudson River valley was a strategically critical area throughout the American Revolutionary War. Through this area moved supplies, men and materiel between the New England states and those further south, something that became vitally important when the British largely abandoned New England as an objective of military control later in the war. In June 1777, General John Burgoyne began an attempt to gain control of this key area by moving south from the British province of Quebec. After his early success at Ticonderoga, his campaign become bogged down in logistical difficulties, not reaching Saratoga, New York, until mid-September.Ketchum (1997), p. 348 Burgoyne held expectations that his campaign would be supported by military forces based in New York City under the command of General William Howe and that the forces would meet at Albany, about south of Saratoga.Ketchum (1997), p. 87
Apparently as a result of poor communications with Lord George Germain, Britain's Secretary of State for the Colonies and the political official in charge of the conflict, General Howe decided instead to attempt the capture of Philadelphia and sailed south with much of his army in July, leaving Sir Henry Clinton in command at New York.Ketchum (1997), p. 82 Howe's instructions to General Clinton were primarily to hold New York City and to only engage in offensive operations that were consistent with that goal. His instructions to Clinton on July 30 included a promise that reinforcements would arrive (but without any promised time) and that Clinton should consider making a move "in favor of General Burgoyne's approaching Albany, with security to Kingsbridge" if the opportunity presented itself.Nickerson (1967), p. 340 A letter from Howe reached Burgoyne on August 3 informing him of his move to Philadelphia and of Clinton's instructions.Ketchum (1997), p. 283 Clinton wrote a letter on September 12 (received by Burgoyne on September 21, after the Battle of Freeman's Farm) that he would "make a push at [Fort] Montgomery in about ten days" if "you think 2000 men can assist you effectually".Nickerson (1967), p. 320

American defenses The highland region of the Hudson River valley (near West Point) was defended by Continental Army troops and state militia under the command of Major General Israel Putnam, who was based at Peekskill. Several miles upriver from Peekskill, just above the Popolopen Gorge where Popolopen Creek enters the Hudson, the Americans had placed a chain across the Hudson to prevent British naval vessels from sailing further upriver. The chain's western end was guarded by Fort Montgomery (named for the late General Richard Montgomery), which also overlooked the gorge to the south. Also on the west side of the river, south of the gorge, they had established Fort Clinton (probably named for General James Clinton).Nickerson (1967), pp. 334–336Roseberry (1981), p. 239 Fort Montgomery, which was still undergoing construction, was under the command of General (and Governor of New York) George Clinton, while Fort Clinton was under the command of his older brother James. Their combined forces numbered about 600.
The primary camp at Peekskill, which any British naval movements would need to pass, had roughly 600 men. Of the men at the three sites, about 1,000 were regular troops, while the remainder were short-term New York militia. Putnam's forces had originally been larger, but General George Washington had ordered some of Putnam's troops to assist either his (Washington's) defense against Howe or Gates' defense against Burgoyne, and a number of local militia companies had been dismissed when Howe's movements became known.Nickerson (1967), p. 337 Putnam received word of the arrival of transports in New York on September 29 and wrote Governor Clinton for assistance, who immediately came south from Kingston to take charge of the forts.
British movements In mid-September (around the time he wrote the letter to Burgoyne), Sir Henry Clinton had around 7,000 men, including around 3,000 poorly trained Loyalists, to defend New York City.Nickerson (1967), p. 338 His letter to Burgoyne had been predicated on the expectation that reinforcements would arrive in time for him to make a move up the Hudson within ten days.Nickerson (1997), p. 341 On September 29, he received a letter from Burgoyne (written after Freeman's Farm) in response to his that was a direct plea for action.
By the end of September, 1,700 additional troops were landed from the fleet arriving at New York. On October 3, Sir Henry started up the Hudson River with 3,000 men in three frigates and a number of smaller vessels.Ketchum (1997), p. 383 The next day, he landed some troops near Tarrytown as a feint to draw Putnam's troops from Peekskill. These troops marched about and then reboarded the ships, which continued north. He then made a similar feinting maneuver at Verplanck's Point, just three miles (4.8 km) south of Peekskill on October 5, where he dislodged a poorly manned American outpost.Nickerson (1967), p. 344 These feinting maneuvers completely fooled Putnam, who drew his troops back into the eastern highlands and sent messages across the Hudson for reinforcements.
Shortly before this last movement, Sir Henry received a dispatch from Burgoyne. In it, Burgoyne explicitly appeals to Clinton for instruction on whether he should attempt to advance or retreat, based on the likelihood of Clinton's arrival at Albany for support. He indicated that if he did not receive a response by October 12, he would be forced to retreat.Nickerson (1967), p. 345 (Clinton's response, not written until October 7, was a markedly formal response, indicating that he was providing the requested diversion and had no expectation of reaching Albany, adding that "Sir Henry Clinton cannot presume to give any Orders to General Burgoyne", as Burgoyne outranked him. Fortunately for Clinton none of the three copies of this letter reached Burgoyne; all of the messengers carrying them were captured.)Ketchum (1997), p. 384
Battle
On the foggy morning of October 6, Sir Henry Clinton landed 2,100 men at Stony Point on the west side of the Hudson and, with the assistance of a Loyalist guide, marched them up onto a local rise called the "Timp". After descending the other side to a place called Doodletown, they encountered a scouting party that Governor Clinton had sent out for reconnaissance, which retreated toward Fort Clinton after a brief exchange of fire. Sir Henry then divided his force into two attack groups to take the forts.Nickerson (1967), pp. 346–347 A force of about 900 men under Lieutenant Colonel Campbell, composed of the 52nd and 57th regiments, a detachment of Hessian chasseurs, and about 400 Loyalists led by Beverley Robinson, began the trek around the gorge toward Fort Montgomery. Meanwhile, Sir Henry waited with the remaining 1,200 men at Doodletown before starting on the trail to Fort Clinton in order to give Campbell time to make the longer journey before beginning simultaneous attacks on the two forts.
Governor Clinton, when alerted to the first skirmish, had immediately sent to Putnam for reinforcements. Shortly after sending that message he learned from scouts that Sir Henry's forces were divided. While waiting for reinforcements (that never came because of Sir Henry's successful feints) his brother James sent 100 men from Fort Clinton toward Doodletown, while he sent another company from Fort Montgomery to oppose Campbell's force.
Fort Montgomery
The detachment from Fort Montgomery numbered about 100 men and included a small artillery piece commanded by Captain John Lamb. Setting up a defensive position about one mile (1.6 km) from the fort, they engaged Campbell's tired forces with spirit. While they were eventually forced to retreat, they were able to spike the field piece before abandoning it to the British. After another stand closer to the fort, supported by 12-pound piece, they again retreated (again spiking the cannon). Because of this dogged defense, Campbell was not in position until about one hour before sunset (having left Doodletown at around 10 am). Offered the chance to surrender, Governor Clinton refused, and the battle was joined.
Campbell arrayed the Loyalists on the left, the German chasseurs in the center, and the British regiments on the right. Despite a vigorous American defense and the death of Campbell, the attacking troops broke into the fort, where they engaged in a near massacre to avenge the loss of Campbell and other officers.Nickerson (1967), p. 349 James Clinton narrowly escaped being killed by bayonet when his orderly book deflected the weapon's point. He and a portion of the fort's garrison escaped into the woods north of the fort.Nickerson (1967), p. 350
