Jackson killed a man in a duel
The ferocious Andrew Jackson had a tendency for pulling out his weapons in response to insults against his honor. According to historians, "Old Hickory" might have engaged in 5 to 100 duelings - one of the interesting facts about Andrew Jackson. When Charles Dickinson referred to Andrew Jackson in a local newspaper as "a worthless scoundrel, a paltroon, and a coward" in 1806, the future president challenged Dickinson to a duel.
Dickinson shot at the signal, striking Jackson in the chest. Jackson's heart was just hit by the bullet by less than an inch. Despite being wounded seriously, Jackson stood his ground, raised his pistol, and fired a shot that killed his enemy. Jackson would live the rest of his life carrying the bullet in his chest and another from a subsequent duel. It's also one of the most interesting facts about Andrew Jackson.
Jackson and Tennessee's governor, John Sevier, engaged in a duel in 1802, which resulted in a stalemate involving their seconds. Thomas Hart Benton, who fought alongside Jackson and twice engaged in legal combat with Charles Lucas, was another frequent dueler. In their second duel in 1817, Benton killed Lucas. Benton worked as Andrew Jackson's right-hand man in Congress while serving as a senator.
