Duel with Aaron Burr Following an exchange of three testy letters, and despite the attempts of friends to avert a confrontation, a duel was nevertheless scheduled for July 11, 1804, along the west bank of the Hudson River on a rocky ledge in Weehawken, New Jersey, a common dueling site at which, three years earlier, Hamilton's eldest son, Philip, had been killed.
At dawn, the duel began, and Vice President Aaron Burr shot Hamilton. Hamilton's shot broke a tree branch directly above Burr's head. A letter that he wrote the night before the duel states, "I have resolved, if our interview [duel] is conducted in the usual manner, and it pleases God to give me the opportunity, to reserve and throw away my first fire, and I have thoughts even of reserving my second fire", which asserts an intention to miss Burr. The circumstances of the duel, and Hamilton's actual intentions, are still disputed. Neither of the seconds, Pendleton or Van Ness, could determine who fired first. Soon after, they measured and triangulated the shooting (both men were the same height), but could not determine from which angle Hamilton fired. Burr's shot, however, hit Hamilton in the lower abdomen above the right hip. The bullet ricocheted off Hamilton's second or third false rib, fracturing it and caused considerable damage to his internal organs, particularly his liver and diaphragm before becoming lodged in his first or second lumbar vertebra.
If a duelist decided not to aim at his opponent there was a well-known procedure, available to everyone involved, for doing so. Hamilton did not follow this procedure. (If so, Burr might have followed suit, and death may have been avoided.) It was a matter of honor among gentlemen to follow these rules. Because of the high incidence of septicemia and death resulting from torso wounds, a high percentage of duels employed this procedure of throwing away fire.[53] Years later, when told that Hamilton may have misled him at the duel, the ever-laconic Burr replied, "Contemptible, if true." [54]
Hamilton was ferried back to New York. After final visits from his family and friends and considerable suffering, Hamilton died on the following afternoon, July 12, 1804. Gouverneur Morris, a political ally of Hamilton's, gave the eulogy at his funeral and secretly established a fund to support his widow and children. Hamilton was buried in the Trinity Churchyard Cemetery in Manhattan alongside other famous Americans such as Robert Fulton.
