David Broderick (1820-1859) and David Terry (1823-1889) had been close friends, but on opposite sides of the slavery issue. Pro-slavery Terry blamed anti-slavery Broderick for causing him to lose re-election for Senator, and he made scathing comments that offended Broderick. Broderick responded in kind, and their argument led to a duel on 13 Sep 1859. Both men were expert marksmen, but Broderick's weapon discharged into the ground during the 1-2-3 count; dueling etiquette dictated that he stand in place while Terry took his shot. Broderick was shot in the right lung, and he died three days later, on 16 September.
