Joseph Robideaux' Trading Post (1826-1840?) - Also called the Blacksnake Hills Trading Post, it was founded by Joseph Robidoux III for the American Fur Company in what would later become St. Joseph, Missouri. The trading post prospered, but after four years, Robidoux returned to independent trading. Doing very well, he ultimately became the "Father" of  St. Joseph when he hired two men to lay out the town, which was an immediate success. The site of the old trading post was at present day Riverfront Park in St. Joseph, Missouri.

Liberty Arsenal (1830's-1861) - In the late 1830s the United States Government established an arsenal in Liberty, a town settled in the 1820's, primarily by southern pioneers. This alleviated many fears of the residents who constantly worried about Indian raids. With the militia guarding the arsenal, the Indians stayed away. But, the town of Liberty had more to fear. Though the city was mostly populated with southern sympathizers, the arsenal was raided by proslavery men during the Kansas-Missouri Border War in 1855.

Surprisingly, when the Civil War broke out, Missouri voted to stay with the Union, even though the state was filled with a Confederate minded population. This placed the state in a war within its own borders. The arsenal was raided again on April 20, 1861 by about 200 men from Clay and Jackson Counties. The Southern sympathizers captured about one thousand muskets, four brass field pieces and a small amount of ammunition. It was the  first civilian Civil War hostility against the Federal government in the State.

The munitions were to be hidden at the home of Henry Lewis Routt near what is now William Jewell College. Routt was eventually captured and tried for treason, found guilty in a military trial and sentenced to hang. But, friends on both the Confederate and union sides interceded and President Abraham Lincoln issued a pardon, one of the earliest of wartime acts of mercy.

Instead, a large proportion of the arms were shipped upriver to the charge of St. Joseph Mayor M. Jeff Thompson. The arms were distributed to Missouri Militiamen and later to the Missouri State Guard. The four brass field pieces became Captain Henry Guibor's State Guard battery.
