The Hamilton & Burr Duel Letters

Best Hamilton Tour in New York City

The duel between Aaron Burr and Alexander Hamilton on July 11, 1804 was one of the most infamous events in American history, rooted in fierce political rivalry and personal animosity. Their conflict erupted after a contentious New York gubernatorial race, where Burr, then Vice President, lost to Morgan Lewis, partly due to Hamilton’s vocal opposition to his candidacy. The final catalyst for the duel came when a letter from Dr. Charles D. Cooper, published in the Albany Register, accused Hamilton of describing Burr as an untrustworthy “dangerous man,” and of having expressed “a still more despicable opinion” of Burr.

The Cooper Letter in the Albany Register

Dr. Cooper’s letter read:

“I assert that Gen. Hamilton and Judge Kent have declared, in substance, that they looked upon Mr. Burr to be a dangerous man, and one who ought not to be trusted with the reins of government.” (1)

Cooper further reported Hamilton’s supposed utterance of an even worse “despicable” opinion, which triggered Burr to confront Hamilton directly. This public airing of private resentments created a scandal Burr felt demanded satisfaction.

Burr’s Letters to Hamilton

Upon seeing Cooper’s published remarks, Burr sent his first challenge letter to Hamilton on June 18, 1804:

“You must perceive, sir, the necessity of a prompt and unqualified acknowledgement or denial of the use of any expression that would warrant the assertions of Dr. Cooper.” (2)

Burr demanded Hamilton either confirm or deny he made the statements attributed to him. Hamilton’s reply was evasive, refusing a categorical answer, which inflamed the conflict. Burr followed up with another letter dated June 22:

“I relied with unsuspecting faith that from the frankness of a Soldier and the Candor of a gentleman I might expect an ingenuous declaration; that if, as I had reason to believe, you had used expressions derogatory to my honor, you would have had the Spirit to Maintain or the Magnanimity to retract them…” (3)

Burr made clear that only an explicit apology or retraction would suffice, expressing disappointment at what he saw as Hamilton’s equivocation.

Hamilton’s Responses

Hamilton’s replies were measured but firm. In his June 20, 1804 letter, Hamilton rebuffed Burr’s demand:

“I have become convinced, that I could not, without manifest impropriety, make the avowal or disavowal which you seem to think necessary.” (4)

Hamilton further explained that his statements about Burr were general political criticisms and not a direct attack on Burr’s honor. He conceded to “abide by the consequences,” implicitly accepting the possibility of a duel. Throughout these exchanges, Hamilton maintained a tone of civility and principle, while trying to avoid a public retraction and escalation, but Burr saw this as evasion.

The Path to the Duel

The repeated written refusals to apologize and escalating tone brought both men to an impasse. Burr closed his final letter:

“Thus, sir, you have invited the course I am about to pursue, and now your silence impose it upon me.” (5)

Hamilton, meanwhile, prepared drafts in case he would not survive, expressing his moral aversion to dueling but accepting the practical realities of honor and reputation in that era.

These exchanges show how the collision of politics and pride produced one of America’s defining moments, ending in Hamilton’s early demise and reshaping the early republic’s view of honor and violence.

The tragic conclusion of the Burr–Hamilton duel reveals a profound complexity at the heart of their relationship, shaped by fifteen years of political rivalry, deep-seated mistrust, and competing ambitions for influence in the new nation. Though both men had worked together in law and served in the American Revolution, their differences became irreconcilable as Burr’s flexible political allegiances repeatedly clashed with Hamilton’s principled Federalism, leading Hamilton to view Burr as an obstacle to the country’s future. Hamilton’s letter before the duel admitted no personal hatred, but emphasized his duty to oppose Burr for the greater good.

For both Hamilton and Burr, the concept of honor was not merely personal character, but a public currency essential for survival in the Early Republic. Burr’s demand for a full retraction was rooted in the era’s sometimes unforgiving standards, where reputation dictated power; refusing the challenge would have meant public humiliation and political death for either man. Hamilton, meanwhile, struggled with the moral consequences of dueling but understood that conceding would compromise his usefulness and legacy as a leader.  Ultimately, their ideas of honor forced them onto the dueling ground—not out of animosity alone, but from a belief that only through defending reputation could they uphold their dominance, even at ultimate personal cost. The heartbreak was not just in the loss of Hamilton’s life, but in the way their fixation on personal honor transformed a private quarrel into a moment that transformed early American political culture.

Hamilton and Burr Together One Week Before the Duel

On July 4, 1804, one week before the infamous duel, the rivals Alexander Hamilton and Aaron Burr, were together at Fraunces Tavern at an event sponsored by the Society of the Cincinnati, whose members were American and French veterans of the Revolutionary War. Fraunces Tavern is one of the stops on the “Hamilton & Washington In New York” Walking Tour.

While the challenge had been established, the date for their encounter at dueling ground in Weehawken was still days away. The artist John Trumball was at Fraunces Tavern and noticed their unusual moods. He reflected on his observations years later in his published autobiography:

“On the 4th of July, I dined with the society of the Cincinnati, my old military comrades, and then met, among others, Gen. Hamilton and Col. Burr. The singularity of their manner was observed by all, but few had any suspicion of the cause. Burr, contrary to his wont, was silent, gloomy, sour; while Hamilton entered with glee into all the gaiety of a convivial party, and even sung an old military song. A few days only passed, when the wonder was solved by that unhappy event which deprived the United States of two of their most distinguished citizens. Hamilton was killed–and Burr was first expatriated, and then sunk into obscurity for life, in consequence of their compliance with a senseless custom, which ought not to have outlived the dark ages in which it had its origin.”

Burr & Hamilton – Dream Team

While many people know about the rivalry between Alexander Hamilton and Aaron Burr and Hamilton’s unfavorable opinion of Burr as a public and private man, it is less known that they were on the same legal team in the scandalous trial of Levi Weeks in 1800. Weeks was accused of murdering his girlfriend, Elma Sands, by throwing her down a well, in what is today SoHo, in December 1799. Weeks retained Burr, Hamilton and Henry Brockholst Livingston, all well-known lawyers to defend him. Weeks was acquitted after only a few minutes of jury deliberation. With strong public sentiment against the verdict, Weeks left New York for Mississippi where he became a builder and architect. His Auburn Mansion in Natchez, Mississippi is National Historic Landmark. Burr and Hamilton would engage in a duel in Weehawken a little over four years later in July 1804.

Aaron Burr’s Surveillance in Weehawken

Mention Weehawken and Aaron Burr and most people will think of the duel with Alexander Hamilton, July 11, 1804, but Aaron Burr has earlier history to the New Jersey township. On July 6, 1778, while New York City was occupied by the British during the Revolutionary War, General William Alexander (also known as Lord Stirling), at the direct request of none other than George Washington, sent Colonel Burr a letter requesting him to provide surveillance on the “motions of the enemy’s shipping” in Weehawken, Hoboken and Bergen Heights. This is the letter:

“General Washington desires me to state that he wishes you would employ three, four, or more persons, to go to Bergen heights, Weehawk, Hoebuck, or any other heights thereabout, convenient to observe the motions of the enemy’s shipping, and to give him the earliest intelligence thereof; whether up the river particularly.  In short, everything possible that can be obtained.”
