Battle of Indian Field
August 31, 1778 · Present-day Bronx, New York
On August 31, 1778, approximately sixty Patriot-allied Stockbridge soldiers operating near the British-held approaches to New York City encountered a coordinated force of British regulars, Loyalist infantry, cavalry, and German troops. The engagement occurred near Cortlandt’s Ridge, in the vicinity of present-day Van Cortlandt Park in the Bronx.
The British-allied force, organized under Lieutenant Colonel John Graves Simcoe and cooperating commanders, used a combination of infantry and mounted troops to envelop the Stockbridge detachment. Captain Daniel Nimham and his son Abraham were killed. The engagement became known as the Stockbridge Massacre because of the severe losses inflicted on the small Indigenous company.

Patriot Objective
Reconnoiter British positions, disrupt enemy patrols, gather intelligence, and contest British movement through the approaches north of Manhattan.
British-Allied Objective
Destroy or disperse the Stockbridge reconnaissance detachment, eliminate its ability to threaten British patrols, and reestablish security along the northern approaches to occupied New York City.
Decisive factors: British intelligence, numerical superiority, coordinated infantry and cavalry, terrain suitable for concealment, and the isolation of a small Patriot reconnaissance company.
The Indian Field memorial commemorates Daniel Nimham and seventeen other Stockbridge soldiers, but the memorial’s eighteen names or commemorated deaths should not be treated as a definitive total for the entire engagement. Modern historical estimates differ considerably.
Historical Background
The Stockbridge Community
The Stockbridge community developed in western Massachusetts during the eighteenth century. Its population included Mohican people and members of other Indigenous communities, including Wappinger and Munsee families.
Christian missions and colonial settlement transformed the community’s political and economic circumstances, but Stockbridge residents retained their own leadership, relationships, and collective interests.
Indigenous Support for the American Revolution
Indigenous nations did not uniformly support either Britain or the American Revolution. Their decisions reflected diplomatic alliances, land concerns, community interests, and differing expectations about the war’s consequences.
Many Stockbridge Mohicans supported the Patriot cause and provided military assistance during the Revolution.
Daniel Nimham
Daniel Nimham was a Wappinger sachem who had spent years defending his people’s land claims and political rights. During the Revolution, he supported the American cause and served as a captain.
His military service was closely connected to the Stockbridge company and its broader participation in the Continental war effort.
Abraham Nimham
Abraham Nimham, Daniel’s son, served as a leader of the Stockbridge soldiers. The unit’s service drew on the military experience of its Indigenous members and their established methods of reconnaissance and light infantry fighting.
Earlier Stockbridge Military Service
Stockbridge soldiers participated in several phases of the Revolution, including service connected with the northern campaigns and the Continental Army. Their military experience extended beyond the reconnaissance operations around New York City in 1778.
British Occupation of New York City
After the 1776 campaign, British forces occupied New York City and maintained fortified positions around Manhattan and its northern approaches.
The surrounding countryside became a contested military zone where reconnaissance, raids, and small-unit engagements occurred frequently.
The Westchester Neutral Ground
Much of the territory north of Manhattan was not permanently controlled by either army. Patriot and British patrols moved through farms, roads, wooded hills, and settlements, gathering intelligence and attempting to restrict enemy operations.
The Stockbridge Company in 1778
During the summer of 1778, the Stockbridge company operated with American forces in the New York region, performing reconnaissance and light infantry duties.
Their knowledge of woodland movement made them valuable in the contested terrain between British-held New York City and Patriot positions farther north.
Escalating Patrol Warfare
Stockbridge soldiers participated in attacks against British patrols during August. These actions contributed to British efforts to organize a larger expedition to locate and defeat the company.
The August 31 Operation
British-allied commanders assembled infantry, cavalry, and German troops for a coordinated movement against Patriot forces near Cortlandt’s Ridge. The resulting engagement devastated the Stockbridge detachment.
Commanders & Participating Forces
Patriot Forces
| Commander or Formation | Organization | Role |
|---|---|---|
| Captain Daniel Nimham | Stockbridge-associated Indigenous forces | Senior Indigenous leader; killed during the engagement |
| Abraham Nimham | Stockbridge company | Company leader; killed during the engagement |
| Stockbridge-Munsee Infantry Company | Patriot-allied Indigenous military company | Reconnaissance, patrolling, and light infantry operations |
| Mohican soldiers | Stockbridge company | Principal component of the Indigenous force |
| Wappinger soldiers | Stockbridge company | Indigenous combatants, including members of Nimham’s community |
| Munsee and other Indigenous soldiers | Stockbridge company | Additional company personnel |
| Nearby Continental and state troops | American forces in the Westchester region | Operated in the wider reconnaissance zone; not all fought in the main encirclement |
Captain Daniel Nimham
Nimham combined Indigenous political leadership with military service. His experience and standing made him an important figure in the Stockbridge company’s operations.
He was killed during the fighting at Indian Field. British accounts describe him resisting the attackers even after the company became surrounded.
Abraham Nimham
Abraham served in a leadership role among the Stockbridge soldiers. He died alongside his father during the August 31 engagement.
The Stockbridge Company
The approximately sixty-man company included experienced Indigenous soldiers whose duties required independent movement, scouting, and the ability to fight in difficult terrain.
It should not be described as a unit composed exclusively of one Indigenous nation or as an untrained civilian gathering.
British-Allied Forces
| Commander or Formation | Organization | Role |
|---|---|---|
| Lieutenant Colonel John Graves Simcoe | Queen’s Rangers | Principal commander in the coordinated operation |
| Lieutenant Colonel Andreas Emmerich | British-allied light troops | Participated in the coordinated movement and encirclement |
| Banastre Tarleton | Mounted Loyalist troops | Led cavalry involved in the engagement |
| Queen’s Rangers | Loyalist provincial corps | Infantry and mounted operations |
| Tarleton’s mounted troops | British-allied cavalry | Rapid movement, pursuit, and attacks against retreating soldiers |
| Hessian jägers | German light infantry in British service | Reconnaissance and support in wooded terrain |
| Other British-allied detachments | Combined operation | Screening, supporting movements, and restricting escape routes |
John Graves Simcoe
Simcoe commanded the Queen’s Rangers, a Loyalist provincial corps known for light infantry and mobile operations. His account of the engagement is a principal source for reconstructing the British perspective.
Andreas Emmerich
Emmerich commanded British-allied light troops operating around Kingsbridge. His force participated in the wider effort to locate and destroy the Stockbridge detachment.
Banastre Tarleton
Tarleton was a British cavalry officer whose mounted troops contributed to the encirclement and pursuit. His later fame in the southern campaigns should not obscure his earlier service around New York.
Hessian Jägers
German jägers were specialized light infantry trained for reconnaissance, skirmishing, and operations in broken terrain. Captain Johann Ewald’s journal provides important contemporary evidence about the engagement.
Battlefield Geography & Terrain
The Northern Approaches to Manhattan
The battlefield lay near the northern edge of British-occupied New York City, where roads and ridges connected Manhattan with Westchester County.
Kingsbridge
Kingsbridge was a strategically important crossing and military position connecting Manhattan with the mainland. British forces used the area as a base for patrols and defensive operations.
Cortlandt’s Ridge
The ridge and surrounding high ground provided observation over roads and approaches. Its wooded slopes and irregular terrain also created opportunities for concealment and ambush.
Van Cortlandt’s Woods
The wooded country around the Van Cortlandt estate formed part of the engagement area. Soldiers moving through the trees could become separated from neighboring units or lose sight of enemy movements.
Indian Field
Indian Field is the historical name associated with the final fighting and burial of Stockbridge soldiers. It lies within the northeastern portion of present-day Van Cortlandt Park.
Mile Square Road
The historic road system connected British positions around Kingsbridge with settlements farther north. Control of these routes was important for patrols, reconnaissance, and military communications.
Tibbetts Brook
Tibbetts Brook and its surrounding low ground influenced movement through the area. The watercourse and adjoining terrain complicated escape and maneuver.
Fields and Woodland Edges
Open fields provided opportunities for mounted troops to move quickly, while wooded ground offered concealment to infantry and Indigenous scouts.
The Encirclement Area
British-allied troops used the combination of roads, fields, and wooded terrain to pressure the Stockbridge company from multiple directions.
The Battlefield Today
Much of the area has been incorporated into Van Cortlandt Park and the surrounding Bronx neighborhoods. Modern roads and development have changed the landscape, but historical research and archaeological reports preserve evidence concerning the battlefield’s approximate location.
The engagement occurred in a transitional landscape of wooded ridges, agricultural fields, roads, and streams. The Stockbridge soldiers were experienced in woodland warfare, but their small number made them vulnerable when British infantry and cavalry approached from multiple directions. Once the British-allied force controlled the likely escape routes, the terrain no longer provided a reliable avenue of withdrawal.
Weapons, Equipment & Logistics
Stockbridge Firearms
Stockbridge soldiers carried firearms suitable for light infantry service, including muskets and rifles. Individual weapons and equipment varied rather than conforming to a single uniform issue.
Traditional Weapons
Contemporary descriptions indicate that some Stockbridge soldiers also carried edged weapons and other traditional equipment. These items could be useful during close combat.
Contemporary Clothing
Captain Johann Ewald described the clothing and equipment of a Stockbridge soldier after the battle. His observations provide a rare contemporary description of an Indigenous soldier serving the American cause.
British Infantry Weapons
The Queen’s Rangers and other British-allied infantry used military firearms and bayonets. Their training emphasized rapid movement and coordinated small-unit fighting.
Cavalry Weapons
Mounted troops carried weapons suited to close combat and pursuit, including sabers and firearms. Their mobility made them especially dangerous to isolated infantry in open ground.
Hessian Jäger Equipment
Jägers commonly carried rifles or other firearms suited to skirmishing. Their specialized equipment and training supported reconnaissance in wooded terrain.
Communications
Small-unit operations depended on officers, messengers, and visual contact. Dense woodland and irregular ground could interrupt communication between separated detachments.
Mobility
The British-allied force combined mounted troops with infantry capable of operating through difficult terrain. This combination allowed the attackers to restrict escape routes while maintaining pressure on the Stockbridge soldiers.
Medical Support
The isolated Stockbridge detachment had limited access to immediate medical care during the battle. Wounded men faced serious danger once the unit became surrounded.
Operational Supply
The battle was a short reconnaissance engagement rather than a prolonged siege. Its outcome depended more on tactical positioning and coordination than on the movement of heavy supplies or artillery.
Intelligence & Operational Planning
Patriot Reconnaissance Operations
American commanders used light infantry and Indigenous scouts to monitor British movements north of Manhattan. The Stockbridge company was particularly suited to this work because of its experience operating in wooded country.
British Patrol Routes
British forces moved regularly through the Kingsbridge and Westchester approaches. Patrols protected communications, gathered intelligence, and attempted to prevent Patriot forces from operating near the city’s defenses.
The August 20 Engagement
On August 20, 1778, Stockbridge soldiers and other American troops participated in an attack against a British-allied patrol. The incident demonstrated the threat posed by Patriot reconnaissance forces operating near British positions.
British Intelligence Response
British commanders received information about the Stockbridge company’s activities and prepared a larger operation to confront it.
Coordinated British-Allied Forces
Simcoe, Emmerich, and other officers organized a force combining infantry, cavalry, and German light troops. The operation sought to use superior numbers and multiple approaches to overwhelm the Patriot detachment.
The Stockbridge Mission
On August 31, the Stockbridge company was operating near Cortlandt’s Ridge as part of American reconnaissance and disruption efforts.
Contact with Enemy Troops
The Stockbridge soldiers encountered what appeared to be a smaller enemy element. The contact drew them toward ground where the larger British-allied force could attack.
Simcoe’s Flanking Attack
Simcoe’s troops struck the Stockbridge formation from the flank, disrupting its movement and reducing the soldiers’ ability to withdraw in an organized manner.
Cavalry Movement
Mounted troops advanced against the Stockbridge soldiers as the engagement developed. Their speed allowed them to threaten retreating men and restrict escape.
Encirclement
The Stockbridge company became trapped between enemy formations. The numerical imbalance made it difficult to establish a stable defensive position.
Close Combat
Despite the encirclement, the Stockbridge soldiers resisted. British accounts describe fighting at close quarters, including attempts to pull cavalrymen from their horses.
The Destruction of the Detachment
Daniel and Abraham Nimham were killed, and the company suffered devastating casualties. Survivors escaped or were separated from the main fighting.
The British-allied force used intelligence and coordinated movement to turn a reconnaissance encounter into an encirclement. The Stockbridge soldiers possessed substantial combat experience, but their small force could not withstand simultaneous pressure from infantry and cavalry. The engagement demonstrates how a numerically superior force could defeat an effective light infantry company by controlling its routes of withdrawal.

Tactical Analysis & Command Decisions
Phase One: British Forces Identify the Threat
Stockbridge reconnaissance operations threatened British patrols around Kingsbridge. British commanders responded by assembling a force substantially larger than the Indigenous company.
Phase Two: The British Plan an Encirclement
Simcoe and cooperating officers coordinated infantry, cavalry, and light troops. Their objective was to prevent the Stockbridge detachment from escaping after contact.
Phase Three: Contact Draws the Stockbridge Forward
The Stockbridge soldiers encountered an enemy element and moved toward it. This placed the company within reach of the larger British-allied formation.
Phase Four: Infantry Strikes the Flank
Simcoe’s infantry attacked from the side, forcing the Stockbridge soldiers to respond to a threat outside their initial line of movement.
Phase Five: Cavalry Restricts Withdrawal
Mounted troops advanced into positions that threatened the company’s retreat. Their mobility made escape across open ground increasingly difficult.
Phase Six: The Company Becomes Surrounded
The Stockbridge detachment faced enemy forces from multiple directions. Its small size prevented it from establishing a continuous defensive perimeter.
Phase Seven: Resistance at Close Quarters
Stockbridge soldiers continued fighting despite the unfavorable situation. Contemporary British accounts acknowledge their determined resistance.
Phase Eight: Loss of Leadership
The deaths of Daniel and Abraham Nimham removed important leaders during the battle. The company suffered additional casualties as the engagement continued.
Phase Nine: Destruction of the Fighting Force
The British-allied troops overwhelmed the detachment. The losses were so severe that the company could no longer operate in its previous form.
Why the British-Allied Force Won
The attackers combined numerical superiority with coordinated infantry and cavalry movements. Their ability to control multiple approaches prevented the Stockbridge soldiers from withdrawing before the encirclement was complete.
Why Stockbridge Experience Was Not Enough
The Stockbridge soldiers were skilled and experienced, but reconnaissance troops were vulnerable when isolated. Their training could not overcome an enemy force several times larger that had successfully blocked escape routes.
The Battle of Indian Field was not a conventional line-of-battle engagement. It was a coordinated ambush and encirclement of a small, experienced Indigenous reconnaissance company. The attackers exploited intelligence, mobility, and numerical superiority. The Stockbridge soldiers’ resistance was significant, but once cavalry and infantry closed around the detachment, its ability to escape or regroup was severely limited.
The Soldier’s Experience
Experienced Indigenous Soldiers
Many Stockbridge soldiers had previous military experience and were accustomed to reconnaissance, skirmishing, and independent movement. Their service reflected organized Indigenous participation in the Patriot war effort.
Reconnaissance Duty
The company’s assignments required soldiers to move through contested territory, identify enemy patrols, and report information to American commanders.
Operating Near British Positions
Patrolling the approaches to Kingsbridge exposed the Stockbridge soldiers to British regulars, Loyalist troops, cavalry, and German light infantry.
The Initial Encounter
When the company encountered enemy troops, its soldiers faced the challenge of determining whether the visible force represented the enemy’s full strength.
The Flanking Attack
British-allied infantry struck from an unexpected direction. The Stockbridge soldiers had to respond while maintaining awareness of other enemy movements.
Fighting Mounted Troops
Cavalry posed a particular danger in open terrain. Stockbridge soldiers resisted at close quarters, and British accounts describe mounted men being pulled from their horses.
The Death of Daniel Nimham
Daniel Nimham was killed during the fighting. His death represented both a military loss and the loss of an important Indigenous political leader.
The Death of Abraham Nimham
Abraham Nimham also died, leaving the Stockbridge community without two prominent members of the same family.
The Survivors
Those who escaped faced the task of returning to American positions and reporting the destruction of the company. The surviving record does not establish the exact experience of every individual soldier.
The Community’s Loss
The deaths affected families and community leadership far beyond the battlefield. The loss of so many military-age men weakened the Stockbridge community at a time when it was already facing serious political and territorial pressures.
Where Was Your Ancestor’s Unit?
The Battle of Indian Field presents unusual genealogical challenges because the principal Patriot formation was an Indigenous military company whose members belonged to several related communities. Research must combine Continental military records with Indigenous community histories, mission records, and contemporary British accounts.
Principal Research Groups
| Formation or Group | Battlefield Connection | Research Priority |
|---|---|---|
| Stockbridge-Munsee Infantry Company | Principal Patriot detachment | Military rolls, Continental correspondence, and community records |
| Daniel Nimham’s command | Stockbridge leadership and reconnaissance | Continental Army records and Wappinger history |
| Abraham Nimham’s company | Patriot Indigenous soldiers | Company service records and Stockbridge records |
| Queen’s Rangers | Principal Loyalist formation | British provincial rolls and Simcoe’s journal |
| Emmerich’s light troops | British-allied operation | British military correspondence |
| Tarleton’s cavalry | Mounted attack and pursuit | Cavalry rolls and British accounts |
| Hessian jägers | German light infantry support | German military journals and service records |
| Nearby Continental and state troops | Wider Westchester operations | Patrol orders and unit returns |
Stockbridge Military Records
Researchers should begin by identifying whether an ancestor served in the Stockbridge company during the summer of 1778. The company’s service history must be reconstructed from military correspondence, returns, and surviving community documentation.
Daniel Nimham
Records concerning Daniel Nimham may appear under variant spellings, including Ninham and Nimham. His political activities before the Revolution are also documented in land-related records.
Abraham Nimham
Abraham’s service should be researched separately from his father’s. Family relationships alone do not establish an individual’s exact rank, military duties, or battlefield position.
Stockbridge-Munsee Community Sources
The Stockbridge-Munsee Community Band of Mohican Indians maintains historical knowledge relevant to the soldiers and their descendants. Tribal histories are essential for understanding community relationships that colonial records may describe incompletely.
Mission and Church Records
Records associated with the Stockbridge mission and local religious institutions may identify families, marriages, baptisms, and other relationships.
Continental Army Correspondence
American officers’ letters and military returns may describe the company’s assignments, service periods, and losses.
British Military Accounts
Simcoe’s journal and Ewald’s diary contain information about the battle and the appearance and conduct of Stockbridge soldiers.
Queen’s Rangers Records
Loyalist military rolls and later settlement claims may identify individual Rangers who served during the New York campaign.
German Military Records
Hessian personnel and unit records may help identify soldiers who participated in the coordinated British-allied operation.
Indian Field Memorial
The memorial at Van Cortlandt Park is an important commemorative source. Its inscription identifies Daniel Nimham and seventeen other Stockbridge soldiers, but it does not constitute a complete verified roster of everyone killed in the battle.
Common Research Errors
Do not assume every Stockbridge soldier was ethnically Mohican.
Do not confuse Daniel Nimham with his son Abraham.
Do not assume every soldier who served in the Stockbridge company was present on August 31.
Do not equate the eighteen deaths commemorated at Indian Field with every historical casualty estimate.
Do not assume every member of the Queen’s Rangers participated in the ambush.
Do not classify all Indigenous nations as British allies during the Revolution.
Do not treat British descriptions of Indigenous soldiers as substitutes for Indigenous community histories.
Establish the ancestor’s community, military organization, commanding officer, and service dates. Determine whether the individual participated in the August 31 reconnaissance operation, served elsewhere in the New York theater, or belonged to a British-allied unit. Compare military records, contemporary journals, mission records, tribal histories, and memorial evidence before assigning battlefield participation.
Battle Outcome & Casualties
Decisive British-Allied Victory
The British-allied force overwhelmed the Stockbridge detachment and eliminated much of its ability to continue organized reconnaissance operations.
Stockbridge Casualties
Historical estimates of Stockbridge deaths range from approximately fifteen to forty. The variation reflects incomplete contemporary returns and differences among later accounts.
Daniel and Abraham Nimham
Both leaders were killed. Their deaths were among the engagement’s most consequential losses for the Stockbridge community.
British-Allied Casualties
British-allied losses were comparatively light. Contemporary accounts identify at least one cavalryman killed, while additional wounded or other losses are less consistently reported.
The Fate of the Company
The losses severely weakened the Stockbridge company and effectively ended its previous role as a major organized Indigenous fighting force in the campaign.
| Category | Stockbridge Patriots | British-Allied Forces |
|---|---|---|
| Command | Daniel and Abraham Nimham | John Graves Simcoe and cooperating officers |
| Strength | Approximately 60 | More than 500 in the wider operation |
| Principal Action | Reconnaissance and defensive resistance | Ambush, flanking, encirclement, and pursuit |
| Killed | Approximately 15–40 in differing estimates | At least one cavalryman reported killed |
| Formation Outcome | Severely depleted | Operation completed |
| Result | Decisive defeat | Decisive victory |
Why It Became Known as a Massacre
The term Stockbridge Massacre reflects the severe losses inflicted on a small, surrounded Indigenous company. It does not by itself establish the precise circumstances of every death or prove that all casualties occurred after surrender.
Historical Uncertainty
Contemporary British reports, later local histories, memorial inscriptions, and modern scholarship do not provide identical casualty totals. A reliable reconstruction must preserve these differences rather than combine them into a single unsupported figure.
Strategic Aftermath
British Security Near Kingsbridge
The victory reduced the immediate threat posed by the Stockbridge detachment to British patrols operating north of Manhattan.
Loss of an Experienced Patriot Unit
American forces lost a small but valuable reconnaissance company whose soldiers had experience in light infantry and woodland operations.
Indigenous Military Sacrifice
The battle illustrates the significant military contributions of Indigenous soldiers who supported American independence. Their service was often overlooked in later accounts emphasizing Continental regulars and state militia.
The Stockbridge Community After the Battle
The deaths of Daniel and Abraham Nimham and many other soldiers weakened the community’s leadership and military capacity.
Postwar Land Dispossession
Despite Stockbridge support for the American cause, the community continued to experience land losses and political pressure after the Revolution.
These developments were part of a longer history of displacement that ultimately led Stockbridge-Munsee descendants westward.
The Legacy of Daniel Nimham
Nimham is remembered both for his military service and for his efforts to defend Wappinger land rights. His career demonstrates the connection between Indigenous political leadership and Revolutionary War service.
The Indian Field Memorial
A memorial dedicated in 1906 commemorates Nimham and other Stockbridge soldiers. It remains an important site of public remembrance in Van Cortlandt Park.
Modern Historical Interpretation
Recent research has emphasized the experience and military importance of the Stockbridge soldiers, challenging older narratives that treated Indigenous participants as marginal figures in the American Revolution.
Battlefield Preservation
Van Cortlandt Park preserves part of the historical landscape associated with the engagement. Archaeological and documentary research continues to clarify the locations and movements of the opposing forces.
The Battle’s Larger Significance
The Battle of Indian Field was a relatively small engagement in terms of total soldiers involved, but its consequences were profound for the Stockbridge community. It remains one of the most significant examples of Indigenous Patriot military service and sacrifice during the Revolution.
Primary Sources & Historical Research
The Battle of Indian Field is documented through British military journals, contemporary descriptions, American military correspondence, archaeological reports, and Indigenous community histories. British eyewitness accounts provide important tactical evidence, but they must be interpreted alongside Indigenous perspectives and later historical research.

Historical caution: The memorial’s commemoration of eighteen deaths is not necessarily the total number killed.
Historical caution: The term massacre should not be used to assert undocumented circumstances surrounding every death.
Genealogical caution: Company membership does not automatically establish an individual’s presence during the August 31 engagement.
The Battle of Indian Field occurred on August 31, 1778, near present-day Van Cortlandt Park in the Bronx. A Stockbridge Indigenous company of approximately sixty Patriot soldiers was attacked by a much larger British-allied force organized under Lieutenant Colonel John Graves Simcoe and cooperating commanders. British infantry and cavalry used coordinated movements to surround the company near Cortlandt’s Ridge. The Stockbridge soldiers resisted, but the detachment suffered devastating losses, including the deaths of Daniel Nimham and his son Abraham. The battle effectively ended the company’s previous role as an organized combat force and became known as the Stockbridge Massacre. Its significance lies in the military service and sacrifice of Indigenous Patriots and the severe consequences the defeat brought to the Stockbridge community.
