On this day, May 30, in 1806, Andrew Jackson, who later became the seventh president of United States, killed a rival in a pistol duel after the man insulted Jackson's wife.

Charles Dickinson, like Jackson, was a prominent racehorse breeder and lawyer in Tennessee. During a gambling dispute, Dickinson called Jackson a coward and his wife, Rachel, a bigamist. Jackson had married Rachel years after she and her first husband had legally separated, but their divorce had not been finalized.

Jackson challenged Dickinson to a duel. They agreed to meet in Kentucky, because dueling was outlawed in Tennessee.

Dickinson, a renowned marksman, fired first and hit Jackson above the heart. Jackson did not fall. He returned fire and killed Dickinson.

Jackson carried Dickinson's bullet in his chest for the rest of his life.
