Summary
Beginning in 1775–1776, the British Crown negotiated contracts with the rulers of six German territories — principally Hesse-Cassel and Hesse-Hanau, but also Brunswick, Anspach-Bayreuth, Waldeck, and Anhalt-Zerbst — to hire approximately 30,000 German soldiers for service in North America. These troops, collectively termed “Hessians” by the colonists (though the label was a misnomer applied regardless of actual origin), began arriving in America in August 1776. The first contingent included nearly 8,000 Hessians among the 32,000 British soldiers in the New York expeditionary force, making foreign troops roughly one-quarter of the initial invasion force. By 1781, German soldiers constituted an estimated one-third of all British forces in North America. Over the full course of the war, approximately 30,000 German auxiliary troops served; roughly 17,313 returned home, about 7,754 died (mostly from disease rather than combat), and some 5,000 remained in North America.
The individual soldiers had little agency in this arrangement. They remained enlisted in their home armies and were obligated to serve by contracts between their territorial rulers and the British Crown. Some were professional soldiers trained in the Frederician style of linear warfare; others were pressed into service or recruited under duress. Compensation flowed to the German princes rather than to the soldiers directly, though British authorities offered land grants to Hessian defectors, a policy that attracted several hundred desertions.
The Treaty Negotiations and Financial Terms
The British Crown concluded subsidizing agreements (Subsidienverträge) with each of the six German states individually in late 1775 and early 1776. The largest contract, signed January 15, 1776, covered 12,000 soldiers from Hesse-Cassel under Landgrave Friedrich II, who received three pounds per man per year in base subsidies, plus “head money” (Kopfgeld) of 30 crowns for every soldier killed or incapacitated in British service — effectively a life-insurance payout to the state rather than the soldier’s family. Over the eight-year war, Hesse-Cassel received approximately £2.9 million from the arrangement, a sum equivalent to nearly thirteen years of ordinary tax revenue. Friedrich II channeled much of this windfall into public works: the Fridericianum museum in Kassel (opened 1779, one of the first public museums in the world) was financed in part from Hessian subsidy payments. Critics in the German lands condemned the practice; Frederick the Great of Prussia is reported to have shown his contempt by levying on Hessian troops marching through his territory to the embarkation ports the same toll he charged on driven cattle — though Frederick himself had earlier leased Prussian troops abroad for comparable financial gain.
The Brunswick contingent of roughly 4,000 men, dispatched under Major-General Friedrich von Riedesel, was assigned to the northern theater. Their surrender at Saratoga in October 1777 (where Riedesel’s force marched into captivity alongside General Burgoyne’s British regulars) became a significant moment in the war and contributed directly to French reassessment of American military capability.

The New York Campaign (1776)
Hessian troops saw their first major combat during the New York campaign of summer–fall 1776. At the Battle of Long Island (August 27, 1776), Hessian forces under General Leopold von Heister attacked the American left flank on Gowanus Heights while British regulars executed the flanking movement through Jamaica Pass. The combined attack routed General Israel Putnam’s division and contributed to the Continental Army’s withdrawal from Brooklyn. At the Battle of Fort Washington (November 16, 1776), a force including approximately 3,000 Hessians stormed the fort’s outer works with fixed bayonets, taking over 2,800 American prisoners — the largest single American loss of the war to that point. General Knyphausen commanded the Hessian assault on the fort’s northern face.
During the subsequent New Jersey pursuit (November–December 1776), Hessian troops occupied Princeton, Trenton, and other New Jersey towns in a loose cordon intended to hold conquered territory through the winter. The assignment of Colonel Johann Rall’s brigade to Trenton — a position many senior officers considered exposed and dangerous — proved fateful.
The Battle of Trenton (December 26, 1776)
The most culturally resonant Hessian engagement occurred at the Battle of Trenton on December 26, 1776. After weeks of defeat and retreat, General George Washington led approximately 2,400 Continental soldiers across the ice-choked Delaware River on the night of December 25–26, achieving surprise in a dawn assault on Rall’s garrison of roughly 1,500 Hessians. The engagement lasted approximately 45 minutes. Rall was mortally wounded during the fight; 22 Hessians were killed, 83 wounded, and 896 captured. American casualties were minimal: 2 soldiers froze to death during the crossing, 4 were wounded in the fighting, and none were killed in battle. Washington followed the victory with a second engagement at Princeton on January 3, 1777, restoring Continental morale after months of near-collapse.
The specific circumstances of the Trenton defeat — a night attack after Christmas, a brigade commander who reportedly dismissed intelligence warnings — generated German myths about Rall’s garrison being surprised while drinking or asleep. Modern historians regard these stories as largely unfounded; the Hessians were roused and formed defensive positions, but Washington’s rapid assault and superior numbers overwhelmed them before they could coordinate. The prisoners were marched through Philadelphia, where their display to the public served as a morale-building spectacle for the Patriot cause.
Service Record and Key Engagements
Hessian and other German troops participated in most significant actions of the Revolutionary War:
- Battle of Long Island (August 27, 1776): major assault role, British-Hessian victory
- Fort Washington (November 16, 1776): Hessian-led storming assault, 2,800 American prisoners
- Trenton (December 26, 1776): Rall’s brigade defeated and captured; reversal of momentum
- Battle of Brandywine (September 11, 1777): Hessian forces in the flanking column
- Battle of Germantown (October 4, 1777): Hessians defended Chew House (Cliveden) against American assault
- Siege of Charleston (March–May 1780): German auxiliaries in the besieging force; 5,400 Americans captured
- Siege of Yorktown (September–October 1781): Hessian troops among the besieged British garrison; surrendered October 19, 1781
Hessian performance was generally regarded as professional and effective by British commanders. General Wilhelm von Knyphausen, who commanded Hessian forces in New York for much of the mid-war period, was considered one of the ablest German commanders and acted as overall field commander during periods when British generals were absent.
Desertions and Post-War Fates
Desertions were a persistent problem. The British government, aware of Hessian reluctance to serve, issued offers of land grants — typically 50 acres per common soldier — to German soldiers who defected to the American side or surrendered and chose to remain. Continental Congress propaganda translated into German was distributed through prisoner exchanges and colonial German communities (particularly in Pennsylvania, which had a substantial German-speaking population) to encourage defection. Estimates of total desertions range from about 5,000 to 6,000 over the course of the war, though some of these men may have been reassigned or lost track of in records rather than genuinely deserting.
After the war ended with the Treaty of Paris (September 3, 1783), surviving German soldiers were repatriated to their home states under the terms of the subsidy contracts. However, several thousand — estimates range from 2,800 to 5,000 — chose to remain in North America, settling primarily in Pennsylvania, New York, and the Carolinas. These soldiers and their descendants contributed to the German-American community, particularly in Pennsylvania German (Pennsylvania Dutch) cultural regions. The descendants of Hessian soldiers who remained in America intermarried with existing colonial German populations and, in time, became part of the American immigrant story the Revolutionary generation had themselves been part of.
Significance
The deployment of foreign mercenaries became a potent political symbol of British tyranny in American Revolutionary discourse. The Continental Congress explicitly condemned the practice in the Declaration of Independence (July 4, 1776): “He has engaged foreign mercenaries to compleat the works of death, desolation and tyranny.” This grievance appeared in the list of charges against King George III, framing the Hessians not merely as military opponents but as evidence of the Crown’s willingness to treat its subjects as enemies rather than people to be governed.
Militarily, the Hessians substantially strengthened the British expeditionary force, whose domestic manpower was insufficient for a sustained transatlantic campaign. Their presence also underscored Britain’s political isolation: the Hessian subsidies attracted criticism across Europe, contributing to the diplomatic climate that enabled France to recognize American independence in 1778 without fearing pan-European condemnation. The Hessian contracts were cited in French diplomatic correspondence as evidence of British overreach and miscalculation. See also: French Alliance & Diplomacy (1776–1778).
For the German principalities, the financial returns were transformative in scale — but morally contested at home, where pamphlets and sermons criticized the princes for treating their subjects as commodities. The controversy fed into later German political discourse about the relationship between rulers and subjects that shaped 19th-century reform movements.
