David Rice Atchison was a mid-19th-century Democratic United States Senator from Missouri. He served as president pro tempore of the United States Senate for six years. Atchison served as a major general in the Missouri State Militia in 1838 during Missouri's Mormon War and as a Confederate brigadier general during the American Civil War under Major General Sterling Price in the Missouri Home Guard. Some of Atchison's associates claimed that for 24 hours—Sunday, March 4, 1849, through noon on Monday—he may have been acting president of the United States. This belief, however, is dismissed by most scholars.
The Battle of Wilson's Creek, also known as the Battle of Oak Hills, was the first major battle of the Trans-Mississippi Theater of the American Civil War. It was fought on August 10, 1861, near Springfield, Missouri.
The Battle of Dry Wood Creek, also known as the Battle of the Mules, was fought on September 2, 1861, in Vernon County, Missouri, during the American Civil War. After his victory at the Battle of Wilson's Creek on August 10, Sterling Price and the Missouri State Guard moved further north into Missouri. A force of Union troops under James H. Lane moved from Fort Scott, Kansas to attempt an interception of Price's army, and set an ambush along Dry Wood Creek. Price's Missouri State Guard troops outnumbered Lane's Kansas troops, and after a two hour skirmish forced Lane to retreat to Fort Scott. In their retreat, Lane's troops abandoned their supplies and mules to the Missourians. Price followed up his victory by continuing his northward march, culminating in another victory at the siege of Lexington, September 13 to 20, before returning south shortly afterwards.
The Battle of Fort Davidson, also known as the Battle of Pilot Knob, was a battle of Price's Missouri Expedition fought on September 27, 1864, near Pilot Knob, Missouri. Confederate troops under the command of Major-General Sterling Price had entered Missouri in September 1864 with hopes of challenging Union control of the state. On September 24, Price learned that Union troops held Pilot Knob. Two days later, he sent part of his command north to disrupt and then moved towards Pilot Knob with the rest of his army. The Confederate divisions of Major-General James Fagan and Brigadier-General John Marmaduke drove Union troops under Brigadier-General Thomas Ewing and Major James Wilson from the lower Arcadia Valley into Fort Davidson on September 26 and on the morning of September 27.
The Battle of Glasgow was fought on October 15, 1864, in and near Glasgow, Missouri as part of Price's Missouri Expedition during the American Civil War.

The siege of Lexington, also known as the first battle of Lexington or the Battle of the Hemp Bales, was a minor conflict of the American Civil War. The siege took place from September 13 to 20, 1861 between the Union Army and the pro-Confederate Missouri State Guard in Lexington, county seat of Lafayette County, Missouri. The victory won by the Missouri Guard bolstered the considerable Southern sentiment in the area, and briefly consolidated Missouri State Guard control of the Missouri River Valley in the western part of the state.
The Second Battle of Lexington was a minor battle fought during Price's Raid as part of the American Civil War. Hoping to draw Union Army forces away from more important theaters of combat and potentially affect the outcome of the 1864 United States presidential election, Sterling Price, a major general in the Confederate States Army, led an offensive into the state of Missouri on September 19, 1864. After a botched attack at the Battle of Pilot Knob, the strength of the Union defenses at Jefferson City led Price to abandon the main goals of his campaign.
The Battle of Byram's Ford was fought on October 22 and 23, 1864, in Missouri during Price's Raid, a campaign of the American Civil War. With the Confederate States of America collapsing, Major General Sterling Price of the Confederate States Army conducted an invasion of the state of Missouri in late 1864. Union forces led Price to abandon goals of capturing the cities of St. Louis and Jefferson City, and he turned west with his army towards Kansas City.
The First Battle of Boonville was a minor skirmish of the American Civil War, occurring on June 17, 1861, near Boonville in Cooper County, Missouri. Although casualties were extremely light, the battle's strategic impact was far greater than one might assume from its limited nature. The Union victory established what would become an unbroken Federal control of the Missouri River, and helped to thwart efforts to bring Missouri into the Confederacy.
The First Battle of Springfield was a battle of the American Civil War that took place on October 25, 1861, near Springfield, Missouri. Following the Battle of Wilson's Creek, the Missouri State Guard, a pro-Confederate militia organization, drove north and defeated a Federal (Union) force in the Siege of Lexington. Following the fighting at Lexington, Federal Major General John C. Frémont began a campaign that drove into southern Missouri. The main body of the Missouri State Guard fell back to Neosho, but a body of roughly 1,000 new recruits commanded by Colonel Julian Frazier was at Springfield. On October 24, Frémont sent a force raised as his bodyguard commanded by Major Charles Zagonyi on a scouting mission towards Springfield. After joining a cavalry force known as the Prairie Scouts at Bolivar, Zagonyi moved on towards Springfield on October 25.
The Missouri State Guard (MSG) was a military force established by the Missouri General Assembly on May 11, 1861. While not a formation of the Confederate States Army, the Missouri State Guard fought alongside Confederate troops and, at various times, served under Confederate officers.
Price's Missouri Expedition, also known as Price's Raid or Price's Missouri Raid, was an unsuccessful Confederate cavalry raid through Arkansas, Missouri, and Kansas in the Trans-Mississippi Theater of the American Civil War.

The Platte Bridge Railroad Tragedy was a bushwhacker attack on the Hannibal and St. Joseph Railroad during the American Civil War on September 3, 1861, in which the train derailed on a bridge over the Platte River east of St. Joseph, Missouri, killing between 17 and 20 and injuring 100. The bridge crosses the river in Buchanan County, between Marion Township on the east, and Washington Township on the west.
The 2nd Kansas Infantry Regiment was an infantry regiment that served in the Union Army during the American Civil War. Recruited in May 1861, it formally organized on June 20. Sent into Missouri, it participated in several small actions in the Springfield area before fighting in the Battle of Wilson's Creek on August 10, where it suffered 70 casualties out of about 600 men present excluded a detached cavalry company. Ordered back to Kansas after the battle, it fought in several small actions in Missouri and later mobilized in Kansas after enemy forces captured Lexington, Missouri, as Kansas was believed to be threatened by the Lexington movement. The unit was disbanded on October 31, with some of its men, including its commander, joining the 2nd Kansas Cavalry Regiment. Colonel Robert B. Mitchell commanded the regiment until he was wounded at Wilson's Creek and Lieutenant Colonel Charles W. Blair took command.

Beginning in late 1863, the 12th Missouri Infantry Regiment was attached to the regiment; the men of the 12th Missouri Infantry were officially merged into the regiment in late 1864. The regiment fought at the battles of Pleasant Hill and Jenkins' Ferry in April. On June 8, 1865, the men of the regiment were paroled and sent back to Missouri.
Hiram Bledsoe's Missouri Battery was an artillery battery that served in the Missouri State Guard and the Confederate States Army during the American Civil War. The battery was formed when the Missouri State Guard was formed as a pro-secession state militia unit in response to the Camp Jackson affair. As part of the Missouri State Guard, the unit was engaged in the Engagement near Carthage and the Battle of Wilson's Creek during mid-1861, before fighting at the Battle of Dry Wood Creek and the Siege of Lexington later that year when Major General Sterling Price led the Guard northwards towards the Missouri River. After the Missouri State Guard retreated into Arkansas in early 1862, Bledsoe's Battery served during the Confederate defeat at the Battle of Pea Ridge in March. The battery, as part of the Army of the West, transferred across the Mississippi River into Tennessee in April, where it left the Guard to enter Confederate service on April 21.
The capture of Sedalia occurred during the American Civil War when a Confederate force captured the Union garrison of Sedalia, Missouri, on October 15, 1864. Confederate Major General Sterling Price, who was a former Governor of Missouri and had commanded the Missouri State Guard in the early days of the war, had launched an invasion into the state of Missouri on August 29. He hoped to distract the Union from more important areas and cause a popular uprising against Union control of the state. Price had to abandon his goal of capturing St. Louis after a bloody repulse at the Battle of Fort Davidson and moved into the pro-Confederate region of Little Dixie in central Missouri.
Nichols's Missouri Cavalry Regiment served in the Confederate States Army during the late stages of the American Civil War. The cavalry regiment began recruiting in early 1864 under Colonel Sidney D. Jackman, who had previously raised a unit that later became the 16th Missouri Infantry Regiment. The regiment officially formed on June 22 and operated against the Memphis and Little Rock Railroad through August. After joining Major General Sterling Price's command, the unit participated in Price's Raid, an attempt to create a popular uprising against Union control of Missouri and draw Union troops away from more important theaters of the war. During the raid, while under the command of Lieutenant Colonel Charles H. Nichols, the regiment was part of an unsuccessful pursuit of Union troops who were retreating after the Battle of Fort Davidson in late September.
