The 1st Missouri Field Battery was a field artillery battery that served in the Confederate States Army during the American Civil War. The battery was formed by Captain Westley F. Roberts in Arkansas in September 1862 as Roberts' Missouri Battery and was originally armed with two 12-pounder James rifles and two 6-pounder smoothbore guns. The unit fought in the Battle of Prairie Grove on December 7, as part of a Confederate offensive. Roberts' Battery withdrew after the battle and transferred to Little Rock, Arkansas, where Roberts resigned and was replaced by Lieutenant Samuel T. Ruffner.

The 8th Missouri Infantry Regiment was an infantry regiment of the Confederate States Army during the American Civil War. From May 1861, the war began affecting events in the state of Missouri. In 1862, Confederate recruiting activities took place in Missouri, and a cavalry regiment was formed in Oregon County, the nucleus being former members of the Missouri State Guard. On September 2, the unit entered Confederate service, but it was reclassified as infantry ten days later. After many of the men transferred to other units, the regiment was reclassified as a battalion on October 19 and named the 7th Missouri Infantry Battalion, also known as Mitchell's Missouri Infantry. It participated in a Confederate offensive at the Battle of Prairie Grove on December 7. During the battle, the unit made several charges against the Union lines but was repeatedly repulsed by artillery fire. The regiment spent most of early 1863 encamped near Little Rock and Pine Bluff in Arkansas.
