Against this mad intrigue one clear-headed individual resolutely set himself--not wholly from disinterested motives. Alexander Hamilton had good reason to know Burr. He declared in private conversation, and the remark speedily became public property, that he looked upon Burr as a dangerous man who ought not to be trusted with the reins of government. He pleaded with New York Federalists not to commit the fatal blunder of endorsing Burr in caucus, and he finally won his point; but he could not prevent his partisans from supporting Burr at the polls.
The defeat of Burr dashed the hopes of the Federalists of New England; the bubble of a Northern Confederacy vanished. It dashed also Burr's personal ambitions: he could no longer hope for political rehabilitation in New York. And the man who a second time had crossed his path and thwarted his purposes was his old rival, Alexander Hamilton. It is said that Burr was not naturally vindictive: perhaps no man is naturally vindictive. Certain it is that bitter disappointment had now made Burr what Hamilton had called him--"a dangerous man." He took the common course of men of honor at this time; he demanded prompt and unqualified acknowledgment or denial of the expression. Well aware of what lay behind this demand, Hamilton replied deliberately with half-conciliatory words, but he ended with the usual words of those prepared to accept a challenge, "I can only regret the circumstance, and must abide the consequences." A challenge followed. We are told that Hamilton accepted to save his political leadership and influence--strange illusion in one so gifted! Yet public opinion had not yet condemned dueling, and men must be judged against the background of their times.
On a summer morning (July 11, 1804) Burr and Hamilton crossed the Hudson to Weehawken and there faced each other for the last time. Hamilton withheld his fire; Burr aimed with murderous intent, and Hamilton fell mortally wounded. The shot from Burr's pistol long reverberated. It woke public conscience to the horror and uselessness of dueling, and left Burr an outlaw from respectable society, stunned by the recoil, and under indictment for murder. Only in the South and West did men treat the incident lightly as an affair of honor.
