American Civil War an Official History:
The Kansas “Red Legs” as Missouri’s Dark Underbelly

The Kansas-Missouri Border 1861-1862: Guerrilla Warfare
The passing of the Kansas-Nebraska Act of 1854 was the beginning of constant political debates about the status of a number of new states of the Union, to be split into Proslavery or Free states as demanded by Congress. Slowly the arguments shifted into armed conflict before the Civil War, and became a guerrilla war in Missouri in 1861. In February 1861, Missouri had decided to remain in the Union, but Governor Jackson wanted to join the Confederacy (CSA), creating a split military, part Pro-Union, the rest pro-Confederate Missouri State Guard, now driven into the Southern part of the state.
