Battle of Fort Washington

On November 16, early on the morning, Knyphausen opened the attack against Col. Moses Rawlings's Virginia and Maryland riflemen who managed to stall the Germans temporarily. Percy advanced on Lt. Col. Lambert Cadwalader's Pennsylvanians but halted them (to the Americans' surprise) to wait for a signal gun from Cornwallis or Mathew. Washington, Greene, Maj. Gen. Israel Putnam, and Brig. Gen. Hugh Mercer crossed to Fort Washington as the firing commenced, but they could do nothing to help Magaw and so returned to Fort Lee to watch the developing action.

Mathew, who had been somewhat delayed by the tide pushed across the river and established a foothold on Laurel Hill. Cornwallis followed with more troops.

Once the signal had gone out to Percy, pressure on the Americans began to mount. Rawlings was force back and Cadwalader withdrew. Confusion was rampant within the reduced perimeter; the retreating Americans poured into the fort. By 3:00 P.M., the Germans had reached Fort Washington from the north, and the British were in view on the east and south. Despite the original surrender terms, another flag was sent into Magaw to ask for capitulation. Realizing that to stand now would create a bloodbath within the crowded fort, Magaw surrendered. The attack cost the British and Germans 67 killed, 335 wounded, and 6 missing. The Americans suffered 54 killed and 2,858 captured, including probably more than 1,000 wounded. The loss of all their arms and equipment was especially damaging. Fort Lee was now untenable and Washington began transporting the ammunition out of the fort.

Account:
In November 1776 the last position the Americans held on Manhattan Island was the area around Fort Washington on the northern tip, known as Harlem Heights. General Nathan Greene commanded the American positions with a discretion to withdraw if he considered it necessary.

General Howe planned three attacks. Brigadier Lord Percy was to attack from the South up the island. Brigadier Matthews with the light infantry and Guards to cross the Harlem River and attack Baxter on the east side, supported by Lord Cornwallis with the grenadiers and the 33rd Foot. The main attack was to be on Rawlings’ position by Hessian troops commanded by General Von Knyphausen. An additional assault was to be carried out on the same side by the 42nd under Colonel Sterling. (the grenadiers, light infantry, Guards, 33rd and 42nd were the corps regularly used for particularly demanding assignments. It is interesting that the 33rd had a consistently high reputation throughout the1740s and 1750s).

Early on the 15th November Howe called on the fort to surrender. This was refused. A bombardment broke out from British batteries across the Harlem River and the frigate Pearl on the American positions.
At 10am Percy advanced to the attack. At noon Matthews landed on Manhattan and began his assault. Baxter was killed and is militia fled into the fort.

Knyphausen crossed onto Manhattan at Kingsbridge and at 10am began his move south. The two Hessian columns assaulted American positions and after a hard fight with Rawlings’ riflemen the Americans fell back into the fort.

Percy attacked Cadwallader in the South and the 42nd landed on the east side and pushed inland behind Cadwallader’s position, forcing the Americans to fall back to the fort.

With all his troops pinned in Fort Washington under heavy fire, Magaw was forced to surrender to the Hessian general Knyphausen.

Casualties: The British side suffered 450 casualties of which 320 were Hessians. The Americans suffe...

Before dawn on November 16, the British and Hessian troops moved out. Knyphausen and his troops were ferried across the Harlem River on flatboats and landed on Manhattan. The flatboatmen then turned down the river to ferry Mathew's troops across the river. However, due to the tide, they were unable to get close enough to the shore to bring the British troops across. Thus, Knyphausen's troops were forced to halt their advance and wait until Mathew could cross. Around 7:00 a.m., Hessian guns opened fire on the American battery on Laurel Hill, and the British frigate Pearl began to fire at the American entrenchments. Also, south of the Fort, Percy had his artillery open fire on the fort itself. Percy's artillery aimed at Magaw's guns which had damaged the British ships several week before.

By noon, Knyphausen and his Hessians restarted their advance. As soon as the tide was high enough, Matthew, accompanied by Howe and his troops, were ferried across the Harlem River and landed, under heavy fire from the American artillery, on the Manhattan shore. The British troops charged up the hillside and dispersed the Americans until they reached a redoubt defended by some Pennsylvania Volunteer companies. After brief fighting, the Americans turned and ran towards the fort.

To the north of the fort, the Hessian right, commanded by Johann Rall, moved up the steep hillside south of Spuyten Duyvil Creek against almost no resistance from the Americans. The Hessians began to bring up their artillery. At this point, the main body of Hessians, 4,000 men, under Knyphausen began to advance down the Post Road, which ran between Laurel Hill and the hill Rall was on. The Hessians crossed swampy land and when they approached the wooded hillside near the fort, they were fired upon by 250 riflemen under the command of Colonel Moses Rawlings. Rawlings' men hid behind rocks and trees and darted from place to place to shoot at the Hessians as they tried to advance through the fallen trees...
