Benedict Arnold occupies a singular place in American memory: the Revolutionary War hero whose name became synonymous with treason. Yet the story of Arnold’s betrayal cannot be fully understood without examining the complex world of the eighteenth century — a world in which Native nations, colonial powers, and emerging American states competed for territory, alliances, and survival. Arnold’s early military career unfolded against the backdrop of the French and Indian War, a conflict that fundamentally reshaped relations between Native nations and European empires. His expeditions through the wilderness of Maine and Canada, his campaigns along Lake Champlain and the Hudson River, and his eventual attempt to surrender West Point all took place in territories that had been home to Indigenous peoples for millennia — the Haudenosaunee Confederacy, the Wabanaki peoples, and the Anishinaabe among them. Understanding Benedict Arnold means understanding the contested landscapes through which he marched.
Born on January 14, 1741, in Norwich, Connecticut, Arnold came from a family of some standing. His mother, Hannah Waterman King, hailed from a prosperous lineage, but his father, Benedict Arnold III, was an alcoholic who systematically squandered the family estate. This early experience of decline shaped Arnold’s lifelong obsession with status, wealth, and recognition. As a young man, he apprenticed at an apothecary business and served in the militia during the French and Indian War — a conflict in which Native nations played decisive roles on both sides of the conflict.
The Rise of a Revolutionary Hero
When the Revolutionary War erupted between Great Britain and its thirteen American colonies in April 1775, Arnold immediately joined the Continental Army. Acting under a commission from the revolutionary government of Massachusetts, he partnered with Vermont frontiersman Ethan Allen and Allen’s Green Mountain Boys to capture the unsuspecting British garrison at Fort Ticonderoga in upstate New York on May 10, 1775. This early victory provided the patriot cause with desperately needed artillery and momentum.
Later that year, Arnold led an ill-fated expedition on a harrowing trek from Maine to Quebec. The purpose was to rally the inhabitants of Canada behind the Patriot cause and deprive the British government of a northern base for mounting strikes into the thirteen colonies. With the enlistments of many of his men expiring on New Year’s Day, Arnold launched a desperate attack against well-fortified Quebec City through a blizzard on December 31, 1775. Early in the battle, Arnold received a grave wound to his leg and was carried to the rear. The assault continued but failed disastrously — hundreds of American soldiers were killed, wounded, or captured, and Canada remained in British hands.
Valcour Island and the Defense of New York
By late 1776, Arnold had recovered sufficiently to take the field again. He correctly predicted that British General Guy Carleton would sail an invading force down Lake Champlain, and he supervised the hasty construction of an American flotilla to meet Carleton’s fleet. On October 11, 1776, the American fleet surprised its foe near Valcour Bay. Although Carleton’s flotilla drove the Americans away, Arnold’s action delayed the British approach long enough that, by the time Carleton reached New York, the battle season was nearly over and the British had to return to Canada. Arnold’s performance at Valcour Island rescued the Patriot cause from potential disaster.
Bemis Heights and the Turning Point at Saratoga
Despite his military successes, Arnold felt he did not receive the recognition he deserved. Indeed, many of his fellow officers reportedly found him vain, emotional, and greedy. One officer presciently stated that “Money is this man’s God, and to get enough of it he would sacrifice his country.”
He resigned from the Continental Army in 1777 after Congress promoted five junior officers above him. General George Washington urged Arnold to reconsider, and he rejoined the army in time to participate in the defense of central New York from an invading British force under General John Burgoyne in the fall of 1777. In the battles against Burgoyne, Arnold served under General Horatio Gates — an officer whom Arnold came to hold in contempt. The antipathy was mutual, and Gates at one point relieved Arnold of his command.
Nonetheless, at the pivotal Battle of Bemis Heights on October 7, 1777, Arnold defied Gates’ authority and took command of a group of American soldiers whom he led in an assault against the British line. His attack threw the enemy into disarray and contributed greatly to the American victory. Ten days later, Burgoyne surrendered his entire army at Saratoga — news that convinced France to enter the war on the side of the Americans. In an unusual tribute, a statue near the Saratoga battlefield commemorates Benedict Arnold’s leg, which he wounded badly both there and in Quebec. The statue shows nothing of Arnold’s body but his leg and does not mention him by name.
Benedict Arnold’s Wife and the Seeds of Betrayal
Arnold seriously wounded the same leg he had injured at Quebec during the battle. Rendered temporarily incapable of field command, he accepted the position of military governor of Philadelphia in 1778. While there, his loyalties began to change. During his term as governor, rumors — not entirely unfounded — circulated through Philadelphia accusing Arnold of abusing his position for personal profit. Questions were also raised about Arnold’s courtship and marriage to the young Peggy Shippen, the daughter of a man suspected of Loyalist sympathies. Arnold and his second wife, with whom he would have five children, lived a lavish lifestyle in Philadelphia, accumulating substantial debt.
The debt and the resentment Arnold felt over not being promoted faster were motivating factors in his choice to become a turncoat. He concluded that his interests would be better served assisting the British than continuing to suffer for an American army he saw as ungrateful. This pattern of personal grievance transformed into political betrayal is a recurring theme in Revolutionary-era history — one that also shaped the fates of Native nations who found themselves caught between competing colonial powers, as explored in accounts of the Proclamation of 1763 and its legacy.
West Point and the Treason
In 1779, Arnold was appointed commander of the American fort at West Point, New York. The fortification commanded the Hudson River — a critical strategic position. But by the end of 1779, Arnold had begun secret negotiations with the British to surrender the post in return for money and a command in the British army.
Arnold’s chief intermediary was British Major John André. André was captured in September 1780 while crossing between British and American lines, disguised in civilian clothes. Papers found on André incriminated Arnold in treason. Learning of André’s capture, Arnold fled to British lines before the Patriots could arrest him. West Point remained in American hands, and Arnold only received a portion of his promised bounty. André was hanged as a spy in October 1780.
Arnold soon became one of the most reviled figures in U.S. history. Ironically, his treason became his final service to the American cause. By 1780, Americans had grown frustrated with the slow progress toward independence and their numerous battlefield defeats. However, word of Arnold’s treachery re-energized the Patriots’ sagging morale.
What Happened to Benedict Arnold?
After fleeing to the enemy side, Arnold received a commission with the British army and served in several minor engagements against the Americans. In one battle, he captured Richmond, Virginia, for the British. After the war, which ended in victory for the Americans with the Treaty of Paris in 1783, Arnold resided in England. The British regarded him with ambivalence, while his former countrymen despised him. “Judas sold only one man,” Benjamin Franklin wrote, “Arnold three million.”
After years of suffering from gout and other health conditions, Arnold died in London on June 14, 1801, at age sixty. Following his death, Arnold’s memory lived on in the land of his birth, where his name became synonymous with the word “traitor.”
Historical Context & Key Cultural Takeaways
The story of Benedict Arnold unfolds within a broader historical landscape shaped by Indigenous peoples and their nations. The Haudenosaunee Confederacy — comprising the Mohawk, Oneida, Onondaga, Cayuga, and Seneca nations — occupied much of the territory through which Arnold’s campaigns moved. The Wabanaki Confederacy of the northern woodlands and the Anishinaabe peoples of the Great Lakes regions were similarly affected by the Revolutionary War’s spillover into their homelands. Fort Ticonderoga, Lake Champlain, and the Hudson River corridor were not empty wilderness but Indigenous homelands and trade routes of immense cultural and strategic significance.
Arnold’s expedition to Quebec in 1775 passed through territory of the Abenaki and other Wabanaki peoples. His campaigns around Saratoga intersected with lands where the Mohawk and other Haudenosaunee nations maintained complex diplomatic relationships with both the British and the Americans. While Arnold’s personal story is one of ambition, grievance, and betrayal, the larger Revolutionary War context involved Native nations making difficult decisions about alliances, sovereignty, and survival — decisions with consequences that would echo for generations.
The irony of Arnold’s legacy — a man remembered solely for his betrayal — contrasts sharply with the historical erasure of Native contributions to and experiences of the Revolutionary era. While Arnold’s name became a byword for treachery, the nations whose homelands witnessed his campaigns often saw their own histories marginalized or forgotten. Understanding Arnold’s story in its full context means acknowledging the Indigenous peoples whose lands and lives were fundamentally transformed by the conflict he helped wage — and then betrayed.
Frequently Asked Questions
What did Benedict Arnold do to become a traitor?
In 1779, while serving as commander of the American fort at West Point, New York, Arnold secretly negotiated with the British to surrender the post in exchange for money and a command in the British army. His intermediary, British Major John André, was captured in September 1780 with incriminating papers. Arnold fled to British lines before he could be arrested, and West Point remained in American hands.
Who was Benedict Arnold’s wife?
Arnold married twice. His first wife was Margaret Mansfield, whom he married in 1767; they had three children before her death in 1775. His second wife was Peggy Shippen, the daughter of a Philadelphia merchant suspected of Loyalist sympathies. Arnold and Peggy had five children together and lived a lavish lifestyle that contributed to the substantial debt that helped motivate his treason.
What role did Native Americans play in the Revolutionary War?
Native nations played complex and varied roles in the Revolutionary War. Some nations, including most of the Haudenosaunee Confederacy (except the Oneida and Tuscarora, who sided with the Americans), allied with the British. Others maintained neutrality or sided with the Americans. The war deeply affected Indigenous communities, disrupting trade networks, displacing populations, and setting precedents for future land seizures and treaty violations.
What was the significance of Fort Ticonderoga and West Point?
Fort Ticonderoga, captured by Arnold and Ethan Allen in May 1775, was strategically important for control of the Lake Champlain corridor and provided the Americans with valuable artillery. West Point, on the Hudson River, was critical for controlling the waterway and preventing the British from splitting the American colonies. Arnold’s attempt to surrender West Point was intended to deliver a decisive strategic advantage to the British.
How is Benedict Arnold remembered today?
Benedict Arnold’s name remains synonymous with the word “traitor” in American culture. However, some historians have noted the irony that his early military contributions were significant, including the capture of Fort Ticonderoga, the naval action at Valcour Island, and his role at the Battle of Bemis Heights. The complexity of his story — hero, wounded warrior, and eventual traitor — continues to fascinate historians and the public alike.
What happened to John André?
British Major John André was captured in September 1780 while returning from a meeting with Arnold, carrying papers that revealed the treason plot. He was tried and hanged as a spy in October 1780. His death was widely mourned in Britain, where he was remembered as a talented and honorable officer.
Conclusion: Legacy, Betrayal, and Historical Memory
The story of Benedict Arnold serves as a lasting cautionary tale about ambition, grievance, and the corrosion of loyalty. Yet it also invites us to consider the broader historical context — a Revolutionary War fought not only by American colonists but within landscapes that had been Indigenous homelands for thousands of years. The Haudenosaunee, Wabanaki, Anishinaabe, and other nations witnessed and participated in the conflict through which Arnold marched, their own sovereignty and survival hanging in the balance while Arnold negotiated his personal deal with the British.
Today, the study of Arnold’s treason and its aftermath offers more than a moral lesson about betrayal. It provides an entry point for understanding the complexity of Revolutionary-era alliances, the displacement of Native peoples, and the ways in which historical memory selectively elevates some figures while obscuring others. The nations whose homelands Arnold traversed have their own stories of resistance, diplomacy, and survival — stories that deserve equal recognition in the retelling of early American history.
