In May 1806, Jackson fought a duel with [[Charles Dickinson (historical figure)|Charles Dickinson]]. Their dispute started over payments for a forfeited horse race, escalating for six months until they agreed to the duel.{{sfn|Moser|Macpherson|1984|pp=78–79}} Dickinson fired first. The bullet hit Jackson in the chest, but shattered against his breastbone.{{sfn|Brands|2005|p=138}} He returned fire and killed Dickinson. The killing tarnished Jackson's reputation.{{sfn|Remini|1977|p=143}}

Later that year, Jackson became involved in former vice president [[Aaron Burr]]'s [[Burr conspiracy|plan]] to conquer [[Spanish Florida]] and drive the Spanish from Texas. Burr, who was touring what was then the Western United States after [[Burr–Hamilton duel|mortally wounding Alexander Hamilton in a duel]], stayed with the Jacksons at the Hermitage in 1805.{{sfn|Meacham|2008|p=27}} He eventually persuaded Jackson to join his adventure. In October 1806, Jackson wrote [[James Winchester (general)|James Winchester]] that the United States "can conquer not only [Florida], but all Spanish North America".{{sfn|Remini|1977|p=149}} He informed the Tennessee militia that it should be ready to march at a moment's notice "when the government and constituted authority of our country require it",{{sfn|Remini|1977|p=148}} and agreed to provide boats and provisions for the expedition.{{sfn|Meacham|2008|p=27}} Jackson sent a letter to President [[Thomas Jefferson]] telling him that Tennessee was ready to defend the nation's honor.{{sfn|Brands|2005|p=120}}

Jackson also expressed uncertainty about the enterprise. He warned the Governor of Louisiana [[William C. C. Claiborne|William Claiborne]] and Tennessee Senator [[Daniel Smith (surveyor)|Daniel Smith]] that some of the people involved in the adventure might be intending to break away from the United States.{{sfn|Remini|1977|p=151}} In December, Jefferson ordered Burr to be arrested for treason.{{sfn|Meacham|2008|p=27}} Jackson, safe from arrest because of his extensive paper trail, organized the militia to capture the conspirators.{{sfn|Remini|1977|p=153}} He testified before a grand jury in 1807, implying that it was Burr's associate [[James Wilkinson]] who was guilty of treason, not Burr. Burr was acquitted of the charges.{{sfn|Brands|2005|p=127–128}}
