A provocative and penetrating investigation into the rivalry between Alexander Hamilton and Aaron Burr, whose infamous duel left the founding father dead and turned a sitting vice president into a fugitive.

In the summer of 1804, two of America's most eminent statesmen squared off, pistols raised, on a bluff along the Hudson River. That two such men would risk not only their lives but the stability of the young country they helped forge is almost beyond comprehension. Yet we know that it happened. The question is why.

In War of Two, John Sedgwick explores the long-standing conflict between founding father Alexander Hamilton and Vice President Aaron Burr. A study in contrasts from birth, they had been compatriots, colleagues, and even friends. But above all they were rivals. Matching each other's ambition and skill as lawyers in New York, they later battled for power along political fault lines that would not only decide the future of the United States but define it. A series of letters between Burr and Hamilton suggest the duel was fought over an unflattering comment made at a dinner party. But another letter, written by Hamilton the night before the event, provides critical insight into his true motivation. It was addressed to former speaker of the House Theodore Sedgwick, a trusted friend of both men and the author's own ancestor. John Sedgwick suggests that Hamilton saw Burr not merely as a personal rival but as a threat to the nation. Burr would prove that fear justified after Hamilton's death when, haunted by the legacy of his longtime adversary, he embarked on an imperial scheme to break the Union apart.
