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. Missouri was officially a neutral state, but its governor, Claiborne Fox Jackson, supported the South and secretly collaborated with Confederate troops.
Nathaniel Lyon was the first Union general to be killed in the American Civil War. He is noted for his actions in Missouri in 1861, at the beginning of the conflict, to forestall secret secessionist plans of the governor Claiborne Jackson.
Claiborne Fox Jackson was an American politician of the Democratic Party in Missouri. He was elected as the 15th Governor of Missouri, serving from January 3, 1861, until July 31, 1861, when he was forced out by the Unionist majority in the legislature, after planning to force secession of the state.
The Camp Jackson affair, also known as the Camp Jackson massacre, occurred during the American Civil War on May 10, 1861, when a volunteer Union Army regiment captured a unit of secessionists at Camp Jackson, outside the city of St. Louis, in the divided slave state of Missouri.
Franz Sigel was a German American military officer, revolutionist and immigrant to the United States who was a teacher, newspaperman, politician, and served as a Union major general in the American Civil War. His ability to recruit German-speaking immigrants to the Union armies received the approval of President Abraham Lincoln, but he was strongly disliked by General-in-Chief Henry Halleck.
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 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 Battle of Roan's Tan Yard, also known as the Battle of Silver Creek, was a minor battle fought during the American Civil War on January 8, 1862, in Randolph County, Missouri. After back-and-forth operations throughout 1861, the pro-Confederate Missouri State Guard under the command of Sterling Price had been confined to southwestern Missouri. In December 1861, Price authorized recruiting and raiding activities in the central portion of the state, with the North Missouri Railroad being a major target. In January 1862, Major W. M. G. Torrence of the Union Army located a Missouri State Guard base in Randolph County and attacked it on January 8 with elements of four cavalry regiments. The camp, which was commanded by Colonel John A. Poindexter, put up little resistance and was soon overrun. Large quantities of supplies were captured in the abandoned camp, which was destroyed. The action at Roan's Tan Yard, along with a Missouri State Guard defeat at the Battle of Mount Zion Church the preceding December, led to a decrease in pro-Confederate activity in central Missouri.
The St. Louis Arsenal is a large complex of federal military weapons and ammunition storage buildings operated by the United States Air Force in St. Louis, Missouri. During the American Civil War, the St. Louis arsenal's contents were transferred to Illinois by Union Captain Nathaniel Lyon, an act that helped fuel tension between secessionists and those citizens loyal to the Federal government.
The Price–Harney Truce was a document signed on May 21, 1861, between United States Army General William S. Harney and Missouri State Guard commander Sterling Price at the beginning of the American Civil War.
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.
Wilson's Creek National Battlefield, located near Republic, Missouri, preserves the site of the Battle of Wilson's Creek. Fought on August 10, 1861, the battle was the first major American Civil War engagement west of the Mississippi River. In the battle, a Confederate army commanded by Benjamin McCulloch and Sterling Price defeated a smaller Union army commanded by Nathaniel Lyon. However, the Confederates were unable to hold much of Missouri, and a Confederate defeat at the Battle of Pea Ridge effectively solidified Union control of the state. Major features include a five-mile automobile tour loop, the restored 1852 Ray House, and "Bloody Hill," the site of the final stage of the battle. The site is located near Republic in southwestern Missouri just southwest of the city of Springfield. It has been a unit of the National Park Service since 1960, and was listed on the National Register of Historic Places in 1966.
During the American Civil War, Missouri was a hotly contested border state populated by both Union and Confederate sympathizers. It sent armies, generals, and supplies to both sides, was represented with a star on both flags, maintained dual governments, and endured a bloody neighbor-against-neighbor intrastate war within the larger national war.
The following Missouri units and commanders fought in the Battle of Carthage of the American Civil War. The Union order of battle is listed separately.

The Capture of Sedalia, officially known as the Affair at Sedalia, Mo., occurred during the American Civil War when a Confederate force attacked the Union garrison of Sedalia, Missouri, on October 15, 1864. The post was outnumbered, having between 600 and 800 men under the command of militia Colonel John D. Crawford and 33 cavalrymen under Captain Oscar B. Queen, compared to about 1,200 led by Brigadier-General M. Jeff Thompson.
