The same year, Burr was soundly defeated in his bid to be elected New York governor. During the campaign, Alexander Hamilton publicly made callous remarks regarding Burr's moral character. Subsequently, Burr challenged Hamilton to a duel, mortally wounding him on July 11, 1804. Burr was indicted for Hamilton's murder in New York and New Jersey, causing him to flee to Georgia, although he remained President of the Senate during Supreme Court Justice Samuel Chase's impeachment trial. Both indictments quietly died and Burr was not prosecuted. Also during the election, certain New England separatists approached Burr, desiring a New England federation and intimating that he would be their leader. However, nothing came of the plot, since Burr had lost the election and his reputation was ruined after killing Hamilton. In August 1804, Burr contacted British Minister Anthony Merry offering to cede U.S. western territory in return for money and British ships.
