The American Revolutionary War’s Campaign for New York and New Jersey, March 1776–January 1777

On March 17, 1776, the 11-month colonists’ Siege of Boston ended when the British troops and their dependants evacuated the town of Boston. A fleet of 120 British ships set sail for a British military base in Halifax, Nova Scotia with nearly 10,000 British troops and over 1,000 dependants. This was discussed in a prior post.

Both sides’ attention next turned to New York City, which then was a town of 25,000 at the southern tip of the island of Manhattan (then known as York Island). This post will review what is known as the Campaign for New York and New Jersey, March 18, 1776, through January 1777.[1]

For the British, the City was an obvious strategic target. It had a large harbor from which the vastly superior British navy could easily command the area and be a base to conquer the middle colonies to the south and west. The terminus of the Hudson (or North) River into that harbor would provide the British with a route north to connect with British forces in what is now Canada and thereby potentially separate New England from the other colonies. Moreover, many British Loyalists lived in the City and thus made it a friendlier host for British troops than Boston had been.

General George Washington

The strategic importance of the City also was obvious to General George Washington. Not knowing that the British troops were going from Boston to Nova Scotia, he was worried that they would instead be sent directly to New York. Therefore, Washington immediately after the British evacuation of Boston sent some colonial regiments from Boston to New York to join the colonial forces already there under the command of General Charles Lee. Thereafter other colonial troops were sent from Boston, including my 5th maternal great-grandfather, Perley Brown, and his brothers William and Benjamin. Perley and his comrades arrived in New York City in late July on a ship from New Haven, Connecticut.[2]

These transfers of troops from Boston were not easy. The men first had to march 100 to 120 miles over five to seven days to the Connecticut ports of New Haven or New London, where they boarded sailing ships to take them via Long Island Sound to New York City.

Archibald Kennedy Mansion

General Washington himself arrived in the City on April 13th and established his headquarters in the Archibald Kennedy Mansion at No. 1 Broadway.[3]

Washington soon discovered that much work still needed to be done to finish the construction of fortifications in Brooklyn on Long Island and on York Island. He was kept busy supervising their continued construction, inspecting the troops and deciding on command assignments and troop deployments.

Another problem faced Washington in the City. The soldiers were growing sickly. Smallpox appeared causing the deaths of several of the men. In the summer heat, “camp fever” became epidemic, and poor sanitation caused dysentery. At least 3,000 to 6,000 men were ill at one time or another, and many died. One of the victims of these illnesses was William Brown (Perley’s brother), who died in a City hospital on August 27th after being sick for eight days. Also sick at this time was brother Benjamin, but his health improved so he could return to active duty.[4]

New York Harbor & Sandy Hook

The long anticipated arrival in New York of the British troops began on June 29th when 120 British ships arrived at Sandy Hook, a barrier spit jutting northward into Lower New York Bay from the New Jersey shore. Three days later (July 2nd) 9,000 British troops from their Nova Scotia base left these ships to establish their new base on the unguarded Staten Island southwest across the harbor from York Island and directly west of the present-day southern part of Brooklyn.

And the British ships kept coming with another 15,000 British and Hessian soldiers soon thereafter. On August 13th 96 more ships entered the harbor plus 20 more the next day. That summer more than 400 British ships with 1,200 cannon and 10,000 sailors under the command of Admiral Lord Richard Howe were anchored in the harbor, and more than 32,000 British and Hessian troops under the command of his brother, General Sir William Howe, were on the nearby land. This turned out to be the largest expeditionary force of the 18th century.

The British, however, did not launch an immediate attack.

Instead General Howe, on July 14th sent a messenger from Staten Island to York Island with a letter addressed to “George Washington, Esq.” conveying an offer to meet and discuss ending the rebellion. Washington’s assistant rejected the letter because it was not addressed to “General George Washington” and because there was no one there by the letter’s simple title. Three days later (July 17th) a second letter was sent; this one was addressed to “George Washington, Esq., etc.,” which also was rejected for the same reason. The next day (July 18th) the British returned to York Island to ask if General Washington would meet with Adjutant General Patterson, and Washington said “yes.”

On July 20th such a peace conference was held at the Kennedy Mansion on York Island. In the midst of polite formalities Washington said he understood that General Howe only had authority to grant pardons, but that those who had committed no wrongs wanted no pardons. This ended these British peace efforts.

In the meantime, General Washington had 19,000 colonial troops in the area, but did not know where the British planned to attack. Therefore, Washington split the Continental Army into fortified positions in Brooklyn on Long Island and in Manhattan with some held in a reserve so-called “Flying Camp” in northern New Jersey to be deployed when they knew where the British were going to attack.

The fighting phase of the campaign for New York and New Jersey began on August 22nd when the British troops invaded Long Island. Thus began what turned out to be the largest battle of the War (the Battle of Long Island or the Battle of Brooklyn) that lasted until August 30th with a British victory.

Staten Island Peace Conference

Soon thereafter– on September 11th (an ironic date in light of its 225th anniversary falling on the day of  the 9/11 attacks of 2001)–another attempt was made to end the rebellion peacefully at the Staten Island Peace Conference.

The Conference participants were Admiral Lord Howe and Continental Congressmen John Adams, Benjamin Franklin and Edward Rutledge. The Americans insisted on British recognition of their recently declared independence. Admiral Lord Howe said he could not do that. Howe was also pressed to repeal the Prohibitory Act that authorized a blockade of the colonies, but he said he could not do that either. Instead, Howe offered to suspend execution of the blockade if the Americans agreed to end hostilities and make fixed financial contributions to Britain. This offer was rejected by the Americans. There was no peace agreement. The War continued.

With the exception of an American victory at Harlem Heights on York Island,  the British won all the military encounters of this campaign through Christmas Eve Day (December 24, 1776) and forced General Washington and the Continental Army to retreat from New York into New Jersey and then from New Jersey into Pennsylvania. Future posts will review the Battles of Long Island (Brooklyn), Harlem Heights and White Plains.

The British victory in this campaign looked secure at that time. But on Christmas Day (December 25th) Washington and 2,400 of his troops made their now famous “crossing the Delaware River” maneuver. They crossed the partially frozen river from Pennsylvania to return to New Jersey to make their successful surprise attack on British and Hessian troops at Trenton, New Jersey. This was followed on January 3rd with another successful colonial attack at Princeton, New Jersey and Washington’s establishing his winter headquarters in Morristown, New Jersey.

Fighting essentially ceased in January 1777 due to winter conditions.

Nevertheless, it has to be said that the British won the Campaign for New York and New Jersey and that the British occupied New York City for the duration of the War.
