The Story
On October 22, 1864, Union General Samuel Curtis anchored a defensive line along the west bank of the Big Blue River, stretching some fifteen miles, to halt Confederate General Sterling Price's army driving from the east. The clash was part of Price's Missouri Raid, the last major Confederate offensive west of the Mississippi, which culminated days later in the decisive Union victory at Westport. The fighting along the Big Blue helped seal the fate of that campaign.
Why it matters
The battles around the Big Blue and Westport ended the Confederacy's final bid to reclaim Missouri, securing the trans-Mississippi West for the Union.
The story behind this marker
AI contextThe era
By the autumn of 1864, the Civil War had ground on for more than three years, and its western theater was a landscape of raids, guerrilla fighting, and shifting control. Missouri was a bitterly divided border state, claimed by both sides and torn by internal conflict throughout the war.
The Confederacy, its fortunes fading in the East, made one last major bid to change the picture in the trans-Mississippi West. A Confederate army pushed north into Missouri in what became known as Price's Missouri Raid, hoping to rally support, seize resources, and disrupt Union control of the region.
The campaign drove toward the western edge of the state, into the area around Kansas City and the Kansas border. There, along the natural barrier of the Big Blue River, Union forces prepared to make a stand against the advancing Confederate column.
People & events
On October 22, 1864, Union General Samuel Curtis set up a defensive line on the west side of the Big Blue River, extending from the Missouri River upstream for some fifteen miles, in an effort to stop Confederate General Sterling Price's army advancing from the east.
This was the Battle of the Big Blue, a hard-fought effort to hold a river line against a determined foe. Curtis aimed to use the waterway as a barrier, forcing Price's men to fight for every crossing while Union forces gathered strength. The Confederates pressed the line, seeking a way through toward the west.
The fighting here did not stand alone. It was one act in a fast-moving drama that would come to a head just days later at nearby Westport, where the campaign reached its decisive climax. The struggle along the Big Blue helped shape the conditions for that outcome, wearing at Price's army and channeling the confrontation toward its end.
Its place in the American story
Price's Missouri Raid was the last major Confederate offensive west of the Mississippi River, and its failure carried real weight. When the campaign collapsed, so did the South's final serious hope of reclaiming Missouri and reshaping the war in the trans-Mississippi West.
The engagements around the Big Blue and Westport secured the region for the Union and closed off a whole avenue of Confederate ambition. In a war increasingly decided in the East, this western campaign was a reminder that the conflict's outcome had to be sealed across a vast and contested continent.
For a divided border state that had suffered years of internal violence, the defeat of Price's raid marked a turning toward the war's end. The Confederacy would not come again in force, and Missouri's fate within the Union was, from this point, effectively settled.
If you visit
Approach this site knowing that the modern landscape of the Kansas City area now overlays what was once a sprawling battlefield. It takes some imagination to see the river line as a military barrier, but the effort is well rewarded.
Orient yourself to the Big Blue River and think about the fifteen-mile line Curtis tried to hold along its western bank. Picture the pressure of an advancing army probing for a crossing, and the urgency of a campaign that would be decided within days at Westport nearby.
The marker makes a meaningful stop for anyone tracing the Civil War in the West, a chapter often overshadowed by the great eastern battles. Read the inscription, get your bearings on the river, and reflect on the last major Confederate push west of the Mississippi—and the Union stand that helped end it.

The park grew up around a home for aging Confederate veterans, and the memorial reflects the Lost Cause remembrance movement of the early 20th century, when such monuments rose across the country decades after the guns fell silent.
Baxter Springs Massacre
Cherokee County, KS
On October 6, 1863, Union General James G. Blunt and roughly a hundred men were ambushed near Baxter's Springs by William Quantrill's Confederate guerrillas, some disguised in Union blue. The deception let the raiders close in before the escort could react, and much of Blunt's party was cut down in the fighting that followed. The episode was one of the bloodiest guerrilla actions on the Kansas-Missouri border.
