Thomas H. Taylor: Thomas Hart Taylor (July 31, 1825 – April 12, 1901) was a Confederate States Army colonel, brigade commander, provost marshal and last Confederate post commander at Mobile, Alabama during the American Civil War (Civil War).  His appointment as a brigadier general was refused by the Confederate Senate after Confederate President Jefferson Davis failed to nominate Taylor, apparently following Davis's appointment of Taylor to the rank.  Nonetheless, Taylor's name is frequently found on lists and in sketches of Confederate generals.  He was often referred to as a general both during the Civil War and the years following it.  Before the Civil War, Taylor served as a first lieutenant in the 3rd Kentucky Volunteer Infantry Regiment during the Mexican-American War.  After that war, he was a cattle driver, farmer and lawyer.  After the Civil War, he was engaged in business in Mobile, Alabama for five years, and after returning to Kentucky, was a Deputy U.S. Marshal for five years and was chief of police at Louisville, Kentucky for eleven years.

Trading Post, Kansas: Trading Post is an unincorporated community in Linn County, Kansas, United States, which is said to be one of the oldest continuously occupied locations in the state.  In 1842 a United States Army fort was built there, but it was soon abandoned.  The fort remained until probably at least 1900.  It was used by troops travelling through the area during the American Civil War and a military post was established in 1861 and lasted until summer 1865.  The Battle of Marais des Cygnes was fought here during the American Civil War.  The location derives its name from a French trading post established there about 1825.

Marais des Cygnes massacre: The Marais des Cygnes massacre ( , , or ) is considered the last significant act of violence in Bleeding Kansas prior to the outbreak of the American Civil War.  On May 19, 1858, approximately 30 men led by Charles Hamilton, a Georgian native and proslavery leader, crossed into the Kansas Territory from Missouri.  They arrived at Trading Post, Kansas, in the morning and then headed back to Missouri.  Along the way they captured 11 Free-Staters, none of whom were armed and, it is said, none of whom had participated in the ongoing violence.  Most of the men knew Hamilton and apparently did not realize he meant them harm.  These prisoners were led into a defile, where Hamilton ordered the men to shoot.  He even shot and fired the first bullet himself.  Five men were killed.
