Hamilton Rowan Gamble, a former justice of the Missouri Supreme Court, is appointed provisional governor of Missouri by the Missouri Constitutional Convention. This position fills the gap left by the deposed Governor Claiborne Fox Jackson, but secessionists continue to charge that the unelected provisional government and Gamble's governorship are illegitimate. As governor, Gamble opposes heavy-handed Union measures, including the emancipation order by General John C. Frémont, which is later rescinded by President Lincoln. On January 31, 1864, Gamble dies in office from an infection sustained from breaking his arm after sticking it out a train window.
