Read Campaign Overview →

Maj. Gen. Sterling Price led a major Confederate cavalry invasion across Missouri seeking to capture St. Louis, seize the state capital at Jefferson City, and rally anti-Union sympathizers. Denied primary fortified objectives, Price marched westward along the Missouri River valley toward Kansas City, culminating in four days of intensive fighting across Jackson County and a crushing retreat southward through Kansas at Mine Creek.

Battle of the Little Blue River

📍 Little Blue River Crossing, east of Independence (Jackson County, Missouri)

On the morning of October 21, 1864, the vanguard of Maj. Gen. Sterling Price’s Army of Missouri encountered Maj. Gen. James G. Blunt’s Federal division defending the crossing of the Little Blue River, several miles east of Independence. Blunt deployed dismounted cavalry and artillery along the bluffs and bridge approaches, stubbornly contesting the Confederate crossing under heavy fire. Although Confederate forces under Brig. Gen. Jo Shelby eventually forced their way across the bridge and outflanked the defenders, Blunt conducted an orderly fighting withdrawal back toward Independence. The engagement delayed Price’s advance by critical hours, permitting Federal forces under Curtis to strengthen their primary fortified line along the Big Blue River.

Second Battle of Independence

📍 Courthouse Square and Downtown Streets, Independence (Jackson County, Missouri)

On the afternoon of October 22, 1864, the cavalry division of Maj. Gen. Alfred Pleasonton struck Price’s Confederate rear guard in and around Independence. Fighting began along the eastern approaches and quickly escalated into vicious mounted and dismounted clashes through the town square and surrounding residential streets. Brig. Gen. William L. Cabell’s and Maj. Gen. John S. Marmaduke’s Confederate brigades attempted to hold the town to protect Price’s enormous supply train moving southwest toward the Big Blue River. Mounted charges by Union cavalry, including the 1st Missouri State Militia Cavalry, broke the Confederate positions, capturing hundreds of prisoners and two artillery pieces, and driving the Confederates westward toward Byram’s Ford.

Battle of Byram’s Ford

📍 Byram’s Ford, Big Blue River Crossing, Jackson County (Jackson County, Missouri)

The Battle of Byram’s Ford spanned two days of combat at the crossing of the Big Blue River south of Kansas City. On October 22, Confederate forces under Shelby forced their way west across Byram’s Ford, breaking Curtis’s Big Blue defensive line and forcing the Federal Army of the Border back to Westport. However, on the morning of October 23, the strategic situation inverted: Pleasonton’s cavalry arrived at Byram’s Ford from the east, confronting Confederate divisions under Marmaduke entrenching the western bluffs. Federal brigades under Col. John F. Philips and Brig. Gen. Egbert B. Brown assaulted across the river under punishing fire, climbed the steep bluffs, and captured the Confederate breastworks. This breakthrough rolled up Price’s rear and allowed Pleasonton to unite with Curtis’s army, precipitating the Confederate collapse at Westport.

Battle of Westport

📍 Brush Creek, Wornall Farm, and Loose Park, Kansas City (Jackson County, Missouri)

The Battle of Westport on October 23, 1864, was the climactic engagement of Price’s Missouri Expedition and the largest battle fought west of the Mississippi River, involving more than 30,000 soldiers. Maj. Gen. Samuel R. Curtis’s Federal Army of the Border engaged Price’s Confederate army along the steep, wooded ravine of Brush Creek south of Westport. Confederate forces under Brig. Gen. Jo Shelby repeatedly repelled Curtis’s frontal assaults across the creek. However, around noon, a local resident guided Curtis’s troops through Swan Creek ravine onto the Confederate western flank. Simultaneously, Pleasonton’s cavalry broke through at Byram’s Ford to the east, striking Price’s rear. Caught in a coordinated pincer, the Confederate lines collapsed, compelling an orderly then desperate retreat southward along the state line.

Battle of Mine Creek

📍 Mine Creek Crossing, near Pleasanton, Linn County (Linn County, Kansas)

Fought on October 25, 1864, two days after Westport, the Battle of Mine Creek occurred in Linn County, Kansas, during Price’s southward retreat corridor. Stalled by an unwieldy wagon train bottlenecked at the steep, muddy banks of Mine Creek, Confederate divisions under Maj. Gen. John S. Marmaduke and Maj. Gen. James F. Fagan turned to make a defensive stand in open prairie. Two vanguard Federal cavalry brigades under Col. Frederick W. Benteen and Col. John F. Philips, numbering approximately 2,600 men armed with repeating carbines, charged directly into the Confederate line of nearly 7,000 men. The ferocity and speed of the mounted charge shattered the Confederate formation. In less than thirty minutes, Union cavalry captured Confederate generals Marmaduke and Cabell, hundreds of enlisted men, and eight artillery pieces.
