New Jersey played a central role in the American Revolution both politically and militarily. It was the site of more than 90 military engagements, including the pivotal battles of Trenton, Princeton, and Monmouth. George Washington led his army across the state four times and encamped there during three hard winters, enduring some of the greatest's setbacks of the war as well as seminal victories.New Jersey in the American Revolution The Society of Cincinnati. New Jersey's decisive role in the conflict earned it the title, "Crossroads of the American Revolution".

New Jersey society was deeply polarized in their views and support of the revolution. Many citizens had emigrated from England and maintained a sense of loyalty to the British Crown; others had economic, social, or familial ties to the mother country. Among the most notable loyalists was the state governor, William Franklin, the illegitimate son of Benjamin Franklin, a leading revolutionary figure. Several Slaves joined sides with the British in return for promises of freedom. For example, Colonel Tye was a slave who escaped and joined the British army, leading constant raids against the people of New Jersey.Streissguth, Thomas (2002). New Jersey. San Diego: Lucent Books, Inc. .

Throughout the Revolutionary War, there were many clashes between the Americans and British within the colony of New Jersey. In total, there were 296 engagements that occurred within New Jersey, more clashes than occurred in any other of the 13 colonies during the war.

Prewar tensions Following the French and Indian War, tensions erupted between the Americans and the British, in part, over who should pay for the war that resulted in the immense territorial gains for the British with their conquest of Quebec and French Canada. After Parliament issued the Sugar Act, the Stamp Act, and the Tea Act, furious protests and outbreaks occurred. One such outbreak occurred in Greenwich Township, New Jersey, in Cumberland County. On December 22, 1774, a group of 40 colonists entered the cellar of loyalist Daniel Bowen and quickly stole and burned chests of tea.

Declaration of Independence

New Jersey representatives Richard Stockton, John Witherspoon, Francis Hopkinson, John Hart, and Abraham Clark were among the men who signed the United States Declaration of Independence. These men, just like all the others, took tremendous risks in order to fight for independence and all went on to serve their newly founded country for the rest of their lives.

Stockton was a New Jersey-born and College of New Jersey-educated attorney who sacrificed his royal judicial title and his considerable international economic interest in order to be an elected delegate for New Jersey at the Continental Congress. Witherspoon was a Scottish immigrant who came to New Jersey to serve as the sixth president of the College of New Jersey. He was a world-renowned Presbyterian minister who emerged as a leading delegate at the Continental Congress. Witherspoon went on to become one of the leaders of the new national Presbyterian church. Hopkinson was somewhat of a renaissance man who was articulate in several fields of the arts and a competent and capable scientist. Perhaps the capstone of his career was his appointment by President George Washington to the federal bench. Hart was a landowner and judge of the Hunterdon County court. Like Stockton, he sacrificed his high standing with the royal court and dedicated his life to the New Jersey General Assembly. After signing the Declaration of Independence, he went on to become the speaker of the New Jersey Assembly. The last of the men, Clark, was an Elizabethtown native who jumped from job to job, working as a farmer, surveyor, transporter, legal adviser, and finally as a politician. He was well liked in all these fields and was a prominent member of society who finally found his home in government.

Battles

Besides being the location of several important battles, New Jersey was also helpful in disrupting British supply units. Forts on the Delaware River could attack British supply troops as they sailed to Philadelphia. Men in whaleboats crossed the Hudson and raided New York City and Long Island, and captured shipping in the Sandy Hook staging area outside New York Harbor. Ships based in south Jersey ports raided British shipping at sea. New Jersey also had several ironworks that provide iron and iron products, such as cannon, for the war effort, besides its food production. The Ford family in Morristown ran a black powder mill that supplied needed powder for the early war effort. The Continental army encamped three years in New Jersey, in the winters of 1777 at Morristown, 1778–79 at Middlebrook (near Bound Brook), and in 1780 again at Morristown. Large parts of the Continental forces wintered in other years in NJ. Raids from British-held New York City from across the Hudson into New Jersey happened very frequently. The British sent men into New Jersey looking for supplies, firewood, cattle, horses, sheep and pigs, and looking to capture leading patriots.

Battle of Fort Lee

The Revolutionary War did not start well for the Continental Army. After difficult losses in the Battle of Brooklyn, General George Washington led his troops towards Manhattan with the British Army in pursuit. On November 16, 1776, Fort Washington, at the northern tip of Manhattan Island, fell to the British.

On the morning of November 20, 1776, British soldiers under Charles Cornwallis captured Fort Lee after a hasty retreat by the American soldiers stationed there under the command of General Nathanael Greene. After gaining control of the Manhattan area, the British ferried up the Hudson River in barges. Washington had dashed off to warn the Americans about the advancing British, and the fort was evacuated. Much equipment and supplies were captured by the British.

Washington then led his 2,000 troops from Fort Lee in a retreat through present-day Englewood and Teaneck across the Hackensack River at New Bridge Landing. Washington continued his retreat through early December, passing through Princeton on the way to the Delaware River.

Ten Crucial Days

The "Ten Crucial Days" were the days from December 25, 1776, to January 3, 1777, when several decisive battles, namely the battles of Trenton, Assunpink Creek and Princeton, were fought between the Continental Army under George Washington and the British army, mostly under Charles Cornwallis. Washington badly needed a victory to prove his army's hope of winning and thus boost morale. It is considered as one of the most significant military offensives in history. According to George Otto Trevelyan: "It may be doubted whether so small a number of men ever employed so short a space of time with greater and more lasting effects upon the history of the world." Frederick the Great called them "the most brilliant in the world’s history." President Coolidge called them "a military exploit of unparalleled brilliancy."

Battle of Trenton

On the night of December 25–26, 1776, the Continental Army under the command of General George Washington made their crossing of the Delaware River. They took the Hessians stationed in Trenton by surprise; the Hessians were not prepared for an attack during a bad storm. In the ensuing Battle of Trenton in the morning of December 26, the Continental Army defeated the Hessians. The Americans attacked in groups, one down the two main streets from the Northeast, the other along the river road. The American cannons denied the Hessians the ability to form up in the streets. The Hessians unsuccessfully attempted to retreat and were completely surrounded by the Continental Army. As a result of the battle, the Americans captured nearly 900 Hessian soldiers within 90 minutes. In addition, they took the supplies that had been placed in Trenton for use by the British army. Washington then had the soldiers recross safely back into Pennsylvania. The battle helped to increase the waning confidence of the Continental Congress.

Battle of the Assunpink Creek

On January 2, 1777, Cornwallis had hoped to engage Washington's army at Trenton after George Washington recrossed the Delaware River, resulting in the Battle of the Assunpink Creek, also known as the Second Battle of Trenton. Cornwallis's initial results were failures. After recapturing Trenton, he ordered charges on defenses fortified by Washington at Assunpink Creek. The Americans, from their defenses, fired volleys at the advancing troops, striking heavy casualties in the British army. Later that night, Washington moved the majority of his army on a surprise attack upon British troops stationed at Princeton. At the same time, he left a few troops to stall Cornwallis by creating false signals (campfires, loud noises, fortification repair) to give the impression that the Continental Army was still stationed in Trenton.

Battle of Princeton

On January 3, 1777, the Continental Army commanded by Washington defeated the British army under Cornwallis at the Battle of Princeton. The initial contact at Princeton was between General Hugh Mercer's advance corp moving toward the Stoney Brook along Quaker Bridge road, against British Col. Charles Mawhood, who was leading most of the 55th regiment and other additional troops toward Trenton. As Mawhood crossed the Stoney Brook, both sides spotted the other. Both sides moved to a nearby hill above the Princeton Road (now US 206). Mawhood opened fire as the Americans came over the ridge, and followed with a bayonet charge. Mercer's men, armed mostly with rifles, were driven off, and Mercer was wounded by bayonets (he died several days later). More American militia moved up to support Mercer, while another column led by General Sullivan moved on the town from the south.

The advancing Militia were also repelled by Mawhood's regiment, although Mawhood was outnumbered 3 or 4 to one, but he and his men stood steadfast. Washington himself lead up more Continentals and encouraged the militia to return to the fight. After a few volleys Mawhood was forced to retreat across the Stoney Brook.

After driving in a detachment of the 55th regiment, Sullivan marched into Princeton. Most of the remaining British forces retreated toward New Brunswick but some took up a defensive position in the stone university building, Nassau Hall.

The Americans set up cannons facing Nassau Hall of Princeton University, and two cannonballs made contact with the walls of the hall. The British soldiers at Princeton were soon forced to surrender to the Americans, and Nassau Hall was recaptured. Cornwallis immediately moved to bring his army to engage Washington. This attempt failed due to a delaying force which damaged the Stoney Point Bridge and delayed the British. These two victories, and the resulting resurgence of the militias from New Jersey, Pennsylvania, Delaware, New York and Connecticut, forced the British out of most of New Jersey, boosting the morale of the Americans. The British were soon forced into an enclave around New Brunswick, giving up the rest of New Jersey."Valis, Glenn. The Battle of Princeton, accessed September 20, 2006

Battle of Millstone

Also known as the battle of Van Nest's Mills, the Battle of Millstone occurred on January 20, 1777. Following the battle of Princeton, Washington's soldiers traveled north following the Millstone River to Somerset Court House (now Millstone, New Jersey), then proceeded to Morristown.

From New Brunswick, a British foraging party of a few hundred men also went to Somerset Court House, reaching Van Nest’s Mill (present day Manville, New Jersey). After seizing flour and livestock, the British unit set up defenses on the Millstone River, including 3 cannons. The militia posted in the area managed to surprise the British party by crossing the cold, waist deep, river and capture many men and to seize back the supplies.
