On April 12, the Revolutionary War began with shots fired on the fort. On September 16, 1776, the Battle of Harlem Heights, sometimes referred to as the Battle of Harlem or Battle of Harlem Plain was fought in western Harlem around the Hollow Way (now West 125th St., and Lenox Avenue) with conflicts on Morningside Heights to the south and Harlem Heights to the north.
The Battle of Harlem Heights was fought during the New York and New Jersey campaign of the American Revolutionary War. The action took place in what is now the Morningside Heights and west Harlem neighborhoods.
The Continental Army, under General George Washington, Commander-in-Chief of the Continental Army, Major General Nathanael Greene, and Major General Israel Putnam, totaling around 1,800 men, held a series of high ground positions in upper Manhattan against an attacking British division totaling around 5,000 men under the command of Major General Alexander Leslie. British troops made a tactical error by having their light infantry buglers sound a fox hunting call, “gone away,” while in pursuit. This was intended to insult Washington, himself a keen fox hunter, having learned the sport from Lord Fairfax during the French and Indian War. “Gone away” means that a fox is in full flight from the hounds on its trail. The Continentals, who were in orderly retreat, were infuriated by this and galvanized to hold their ground. After flanking the British attackers, the Americans slowly pushed the British back. After the British withdrawal, Washington had his troops end the pursuit. The battle went a long way to restoring the confidence of the Continental Army after suffering several defeats. It was Washington’s first battlefield victory of the war.
After a month without any major fighting between the armies, Washington was forced to withdraw his army to White Plains when the British moved into Westchester County and threatened to trap Washington in Manhattan. Washington suffered two more defeats, at White Plains and Fort Washington. After these two defeats, Washington and the army retreated across New Jersey to Pennsylvania. The New York and New Jersey campaign ended after the American victories at Trenton and Princeton.
On August 27, 1776, British troops under the command of General William Howe flanked and defeated the American army at the Battle of Long Island. Howe moved his forces and pinned the Americans down at Brooklyn Heights, with the East River to the American rear. On the night of August 29, General George Washington, evacuated his entire Army, 9,000 men, and their equipment across the water to Manhattan.
Washington set up shop at the Morris-Jumel Mansion (photo above) “because he could see river to river” (also known as the Roger and Mary Philipse Morris House), located in Washington Heights in Harlem on 162nd Street. It served as a headquarters for both sides in the American Revolution.
It was built by Roger Morris in 1765 and reflects the Palladian style of architecture. Morris, the nephew of a successful English architect, was greatly influenced by the designs of the 16th-century Italian architect Palladio. His residence includes a monumental portico and pediment, supported by grand Tuscan columns, and a large, two-story octagonal addition at the rear. The octagon room is believed to be the first in the country.
The mansion is located on a parcel known as “Mount Morris” from which the Harlem River, the Bronx, Long Island Sound, the Hudson River and the Jersey Palisades are visible. It is located within the boundaries of the Jumel Terrace Historic District.
Roger Morris and Mary Philipse lived in the mansion for ten years. It was from 1765 to 1775, when the war started. They got married in the parlor, which can be seen today.
Between September 14 and October 20, 1776, General George Washington used the mansion as his temporary headquarters. General Washington was standing a top the Jumel Mansion looking south as the British burned farms in lower Manhattan.
This house is one of the major remaining landmarks of Battle of Harlem Heights and one of the only homes in the nation that still has a colonial garden, after which it became the headquarters of British Lieutenant General Sir Henry Clinton, and the Hessian commander Baron Wilhelm von Knyphausen. The Morris-Jumel Mansion later hosted many other distinguished visitors, including dinner guests John Adams, Thomas Jefferson, Alexander Hamilton and John Quincy Adams.
Stephen Jumel and his wife Eliza Jumel purchased the house in 1810. After Stephen’s death, Eliza married the controversial ex-vice president Aaron Burr who lived at the house briefly in the 1830s. After Burr’s death in 1836, Eliza lived in the house alone until she died in 1865. In 1882, the Morris heirs broke up the 115 acres of the estate into 1058 lots.
On a rocky eminence overlooking one of the rivers, Fitz-Greene Halleck wrote his famous lines on the Greek patriot “Marco Bozzaris.”
On September 15, Howe landed his army at Kip’s Bay, Manhattan. After a bombardment of the American positions on the shore, 4,000 British and Hessian troops landed at Battle of Kip’s Bay. The American troops began to flee at the sight of the enemy, and even with Washington’s arrival on the scene they refused to obey orders and continued to flee.
After scattering the Americans at Kip’s Bay, Howe landed 9,000 more troops, but did not cut off the American retreat from New York City. Washington had all of his troops in the City on their way to Harlem Heights by 4:00 pm and they all reached the Heights by nightfall.
On the morning of September 16, Washington received word that the British were advancing. Washington, who had been expecting an attack, sent a reconnoitering party of 150 men under the command of Lieutenant Colonel Thomas Knowlton to probe the British lines. At daybreak, Knowlton’s troops were spotted by the pickets of the British light infantry. The British sent two or three companies to attack the enemy. For more than half an hour the skirmish continued, with fighting in the woods between two farmfields. When Knowlton realized that the numerically superior British forces were trying to turn his flank, he ordered a retreat. The retreat was organized and conducted with no confusion or loss of life.
The British quickly pursued the Americans and were reinforced with the 2nd and 3rd Battalions of Light Infantry, along with the 42nd Highlanders. During the retreat, the British light troops played their bugle horns signaling a fox hunt, which infuriated the Americans. Colonel Joseph Reed, who had accompanied Knowlton, rode to Washington to tell him what was going on and encouraged him to reinforce the rangers. Instead of retreating, Washington, in what Edward G. Lengel calls “an early glimmer of the courage and resolve that would rally the Continentals from many a tight spot later on”, devised a plan to entrap the British light troops. Washington would have some troops make a feint, in order to draw the British into a hollow way, and then send a detachment of troops around to trap the British inside.
The feint party was composed of 150 volunteers who ran into the hollow way and began to engage the British. After the British were in the hollow way, the 150 volunteers were reinforced by 900 more men. All of the troops were stationed too far away from one another to do much damage.
The flanking party consisted of Knowlton’s Rangers, which had been reinforced by three companies of riflemen, in total about 200 men. As they approached, an officer accidentally misled the men, and the firing broke out on the British flank, not their rear. The British troops, realizing that they had almost been surrounded, retreated to a field, where there was a fence. The Americans soon pursued and, during the attack, Knowlton was killed. Despite this, the American troops pushed on; driving the British troops beyond the fence to the top of a hill. When they reached the hill, the British forces received reinforcements; including some artillery. For two hours, the British troops held their ground at the top of the hill until the Americans once again forced them to retreat into a buckwheat field.
Washington was originally reluctant to pursue the British troops, but after seeing that his men were slowly pushing the British back, he sent in reinforcements and permitted the troops to engage in a direct attack. By the time that all of the reinforcements arrived, nearly 1,800 Americans were engaged in the buckwheat field. To direct the battle, members of Washington’s staff, including Nathanael Greene, were sent in. By this time, the British troops had also been reinforced; bringing their strength up to about 5,000 men.
For an hour-and-a-half, the battle continued in the field and in the surrounding hills until, “having fired away their ammunition”, the British withdrew. The Americans kept up a close pursuit until it was heard that British reserves were coming, and Washington, fearing a British trap, ordered a withdrawal. Upon hearing Washington’s orders to withdraw, the troops gave a loud “huzzah” and left the field in good order.
The British casualties were officially reported by General Howe at 14 killed and 78 wounded. However, a member of Howe’s staff wrote in his diary that the loss was 14 killed and 154 wounded. David McCullough gives much higher figures of 90 killed and 300 wounded. The Americans had about 30 killed and 100 wounded, including among the dead Lieutenant Colonel Knowlton and Major Andrew Leitch. The American victory raised morale in the ranks, even among those who had not been engaged. It also marked the first victory of the war for the army directly under George Washington’s command.
There was little fighting for the next month of the campaign, but Washington moved his army to White Plains in October after hearing that the British were attempting to trap him in Manhattan.
And so ended the Battle of Harlem or Battle of Harlem Plain.
