The Battles of Trenton and Princeton remain among the most consequential campaigns of the American Revolution. Between December 26, 1776, and January 3, 1777, General George Washington’s Continental Army crossed the ice-choked Delaware River and struck two rapid blows—first against a Hessian garrison at Trenton, then against British regulars at Princeton. Yet these ten days must also be read within a wider North American frame: the war unfolded on lands of the Lenape, Haudenosaunee, and other Indigenous nations, and it drew in German auxiliaries whose presence would shape later migrations onto Native territories. Understanding Trenton and Princeton means understanding a winter campaign fought in a contested Indigenous landscape as much as a colonial one.
The Road to Trenton: A Broken Army in a Contested Country
Since August 1776, British forces under General William Howe had driven the Continental Army south out of New York. On November 16, the British overran Fort Washington in Manhattan, taking roughly 2,000 Americans prisoner. Washington then led his shrinking force across New Jersey, a region whose Indigenous Lenape peoples had already endured decades of colonial encroachment and displacement. By mid-December, the army crossed the Delaware River into Pennsylvania, camping short of food, ammunition, and supplies.
Washington understood that without decisive action the Continental Army would dissolve when enlistments expired at year’s end. He planned a three-pronged assault on the Hessian garrison at Trenton: his main force of about 2,400 men, a diversionary force of 1,900 under Colonel John Cadwalader, and a blocking movement by General James Ewing’s 700 men. In the end, neither Cadwalader nor Ewing crossed.
Crossing the Delaware on Christmas Night
Washington’s men and cannons crossed the icy river in boats and began a nineteen-mile march toward Trenton through freezing sleet. The Hessian force at Trenton numbered about 1,400 under Colonel Johann Rall. Although Rall had received warnings of colonial movement, his soldiers were exhausted and unprepared—though the popular rumor that they were drunk from Christmas celebrations is unfounded.
The Battle of Trenton: December 26, 1776
Approaching the town, Washington divided his forces, sending flanking columns under General Nathanael Greene and General John Sullivan, while Colonel Henry Knox‘s artillery fired on the garrison. Rall attempted to rally his troops but never established a defensive perimeter; he was shot from his horse and fatally wounded. The Hessians quickly surrendered. In total, 22 were killed, 92 wounded, 918 captured, and 400 escaped. The Americans suffered two frozen to death and five wounded.
Realizing his men could not hold Trenton against British reinforcements, Washington withdrew across the Delaware. On December 30 he crossed back into New Jersey with about 2,000 men, then urged militiamen whose terms had expired to stay on for six weeks.
Between Trenton and Princeton: The Second Trenton Fight
On New Year’s Day, Washington’s force of roughly 5,000 poorly trained men massed at Trenton. The next day, Lord Charles Cornwallis arrived with about 5,500 troops. After skirmishes at the American lines and three failed attempts to cross the bridge at Assunpink Creek, Cornwallis halted for the night, assuming Washington was trapped.
That night, Washington left 500 men to keep campfires burning while the rest of the army marched north toward Princeton. Torches were extinguished and wagon wheels muffled in heavy cloth to conceal the movement.
The Ambush on the Road to Princeton
At dawn on January 3, 1777, Cornwallis woke to find his opponent gone. Washington sent a small force under General Hugh Mercer to destroy a bridge; Mercer’s men encountered Redcoats under Lieutenant Colonel Charles Mawhood, and Mercer was killed. Arriving militiamen under Colonel Cadwalader had little effect. Then Washington himself rode between the firing lines until his terrified horse refused to continue—and the Americans rallied and broke through Mawhood’s lines.
Alexander Hamilton at Nassau Hall
During the Battle of Princeton, Alexander Hamilton—later the first Secretary of the U.S. Treasury—fired cannons at British troops blockaded in Nassau Hall, the main building of the College of New Jersey (now Princeton University). Three years earlier, Hamilton had applied to the college and been rejected when he asked to take courses at his own pace. His artillery work at Princeton stands among the earliest military contributions of a figure whose later policies—including federal authority over Native lands—would shape U.S.–Indigenous relations for generations.
Importance of the Battles of Trenton and Princeton
Washington wanted to advance to New Brunswick but was overruled by his officers—fortunate, as Cornwallis’s men were moving there. Instead, the army marched to Morristown in northern New Jersey, where it established winter quarters safe from British incursions. The victories reasserted American control over much of New Jersey and dramatically improved the morale and unity of the colonial army and militias.
At Princeton, the Continentals had defeated a regular British army in the field. Washington had also demonstrated that he could unite soldiers from every colony into an effective national force—an organizational template later applied to campaigns across the Indigenous homelands of the Ohio Country and the Southeast. For context on the wider conflict, see Revolutionary War timeline, facts, and battles, and for the German auxiliaries’ role, why Germans fought in the Revolutionary War for the British.
Hessian Soldiers and the Indigenous Frontier
The Hessian mercenaries captured at Trenton were among the thousands of German auxiliaries hired by Britain. Many of these prisoners were eventually exchanged or released—and some, after the war, settled in North America, entering regions that remained Indigenous territory under the Proclamation of 1763. Understanding how these settlements pressed westward illuminates the long chain of dispossession explored in when Native Americans briefly won back their land.
Historical Context & Key Cultural Takeaways
- Ten decisive days: Washington won two battles—Trenton on December 26, 1776, and Princeton on January 3, 1777—in a single winter campaign that restored colonial momentum.
- Rall’s garrison defeated: The Hessian force at Trenton numbered roughly 1,400; American losses were two dead from freezing and five wounded.
- Assunpink Creek stalemate: Cornwallis’s three failed attempts to cross the bridge before halting proved his greatest tactical error.
- The Mohawk Valley connection: Hessian and German consolidation in North America would later overlap with Indigenous-settler friction that shaped diplomacy with the Haudenosaunee Confederacy and Ohio Country nations.
- Hamilton’s precedent: His artillery at Nassau Hall marked the rise of a figure whose federal policies bore directly on Native sovereignty.
- Morristown and beyond: Winter quarters at Morristown set a military pattern later repeated in the Revolution’s later campaigns through Indigenous territories.
Frequently Asked Questions
When were the Battles of Trenton and Princeton fought?
The Battle of Trenton was fought on December 26, 1776. The Battle of Princeton followed on January 3, 1777. Together they formed a ten-day campaign that began with Washington’s Christmas Night crossing of the Delaware.
How many Hessian soldiers were captured at Trenton?
Of roughly 1,400 Hessians under Colonel Johann Rall, 918 were captured, with 22 killed, 92 wounded, and 400 escaped. The Americans lost two men to freezing and sustained five wounded.
What role did Alexander Hamilton play at Princeton?
Hamilton, later the first U.S. Secretary of the Treasury, commanded artillery that fired on British troops occupying Nassau Hall at the College of New Jersey. He had previously been rejected by the college.
Why did Washington march to Morristown afterward?
After Princeton, Washington’s officers overruled his desire to advance to New Brunswick—fortunate, since Cornwallis’s troops were moving there. The army instead marched to Morristown, New Jersey, where it established winter quarters safe from British incursions.

Concluding Synthesis: From New Jersey to Native Homelands
The victories at Trenton and Princeton were tactical in scope but strategic in consequence—they preserved the Continental Army and convinced colonial leadership that a national force was sustainable. That army would soon deploy into the Ohio Country, the Mohawk Valley, and the Southern backcountry, where its campaigns collided directly with Indigenous homelands. The Christmas crossing of the Delaware thus sits on a longer arc: a revolution that began as a colonial dispute over taxation ultimately reshaped the political geography of every Native nation east of the Mississippi. Preserving the memory of Trenton and Princeton requires holding both truths together—the valor of Washington’s men and the costs borne by the peoples whose lands were contested.
