Fought October 21-23, 1864 across what is now Westport, the Country Club Plaza, and Loose Park, the Battle of Westport was the largest Civil War engagement west of the Mississippi River and is often called the “Gettysburg of the West.” A Union victory under Major General Samuel R. Curtis broke Confederate Major General Sterling Price’s Missouri Raid and effectively ended organized Confederate operations in the trans-Mississippi theater.
Summary
Over three days in late October 1864, approximately 30,000 Union and Confederate soldiers clashed across a ten-mile arc south of the Missouri River — from the Big Blue River on the east, through the village of Westport, to the bluffs above the Kansas River on the west. The decisive engagement on October 23, 1864 was fought largely on ground now occupied by Loose Park and the Country Club Plaza. Union forces under Maj. Gen. Samuel R. Curtis (Army of the Border) and Maj. Gen. Alfred Pleasonton (cavalry pursuit from the east) crushed Confederate Maj. Gen. Sterling Price’s Army of Missouri, ending Price’s two-month, 1,500-mile raid through the state and removing the last serious Confederate military threat west of the Mississippi.
Background
Price’s Missouri Raid (September-October 1864)
By autumn 1864 the Confederacy was collapsing in the East but the trans-Mississippi command still hoped a dramatic strike into Missouri could swing the November presidential election against Abraham Lincoln, divert Union forces from Sherman’s march, or even recapture Missouri for the Confederacy. Sterling Price, a former Missouri governor, led roughly 12,000 cavalry and conscripts north from Arkansas in September 1864.1
Price’s raid moved east first — toward St. Louis — but heavy Union defenses turned him west along the Missouri River. By mid-October he was approaching Kansas City, the strategic prize anchoring the western end of the state and the gateway to Kansas. Price’s force had grown via Missouri Confederate recruits but had also been ground down by skirmishes at Pilot Knob, Glasgow, Lexington, the Little Blue, and Independence.
The defenders
Union forces converging on Westport had two commands:
- The Army of the Border under Maj. Gen. Samuel R. Curtis — a hastily assembled mix of regular Union cavalry and infantry plus the Kansas State Militia (volunteer state troops, many of whom had refused to cross into Missouri until the threat to Kansas became existential).
- The Provisional Cavalry Division under Maj. Gen. Alfred Pleasonton, a veteran Eastern Theater commander, pressing Price’s rear from the east.
Westport itself was a small but commercially important village (westport), the original outfitting point for the Santa Fe and Oregon Trails, founded in 1833 by John Calvin McCoy. The town’s residents were divided in sympathy — Missouri was a slave state that had not seceded, and the border region around Westport had endured ten years of guerrilla warfare known as “Bleeding Kansas” before the formal Civil War began.
The battle
October 21 — Action at the Little Blue
Price’s army pushed Union forces back across the Little Blue River east of Independence. Curtis fell back toward the Big Blue River, the last defensible line before Kansas City itself, while Pleasonton’s cavalry began closing from the east.
October 22 — Byram’s Ford and the Big Blue line
The Confederate Army of Missouri attempted to force a crossing of the Big Blue at Byram’s Ford (today preserved as Big Blue Battlefield Park in eastern KCMO). Brig. Gen. Joseph O. Shelby’s Confederate cavalry broke through Union defenses in the late afternoon. Curtis’s forces fell back toward Westport. By nightfall Price’s army held the line of the Big Blue but Pleasonton was now hard on his rear.
October 23 — The decisive engagement
The third day saw the main battle. Price was caught between Curtis’s force to the north (along Brush Creek, in the area now occupied by the Country Club Plaza and Westport) and Pleasonton’s cavalry coming up from the south and east.
The morning fighting centered on Brush Creek itself — Union forces under Curtis pushed south across the creek and engaged Confederates on what is now the south side of the Plaza and into the open ground of present-day Loose Park. Initial Union assaults were repulsed; Confederate troops held the high ground in the rocky outcrops along what is today 55th Street.
A flanking movement by Union forces, reportedly guided by a local farmer named George Thoman, found a path through the brush and timber to turn the Confederate left flank.2 When Pleasonton’s cavalry simultaneously broke through Confederate rear positions at Byram’s Ford to the east, Price’s army began to disintegrate. By late afternoon the Confederate retreat had become a rout.
Price retreated south through Kansas (paralleling the future state-line road), pursued by Pleasonton’s cavalry. The Confederate force was decimated by further engagements at Mine Creek in eastern Kansas on October 25 and never recovered.
Casualties and scale
Total casualties are uncertain — estimates range from 1,500 to 3,000 killed, wounded, and missing across both sides combined.3 Approximately 29,000 men were engaged across the three-day campaign, making it the largest battle ever fought west of the Mississippi.
Wounded soldiers from both armies were treated at the John Wornall House at present-day 61st Terrace and Wornall Road, which served as a field hospital during and after the battle. The house — built 1858 by John Wornall, a slaveholding Missouri farmer — survives as a museum.
Immediate aftermath
The Confederate threat to Kansas City and Kansas evaporated within a week. Price’s broken army straggled south through Indian Territory back to Arkansas; fewer than half of his original force returned. The raid achieved none of its strategic objectives — Lincoln won re-election in November, Sherman completed his March to the Sea, and Missouri remained firmly in Union hands.
In Kansas City the battle was a local trauma. Residents had buried wounded in their gardens and ridden out the fighting in cellars. The damage to Westport’s commercial infrastructure accelerated the village’s eventual absorption by the growing Town of Kansas to the north (which became Kansas City). By the early 1900s Westport had been formally annexed into KCMO.
Long-term significance
- Strategic. Westport ended major Confederate military operations in the trans-Mississippi theater. The Confederacy had no further capacity to threaten Missouri or Kansas.
- Civic memory. The battle is the single most-significant historical military event on Kansas City soil. It is commemorated at multiple sites across the modern city.
- Geographic legacy. The ground fought over — Westport, Brush Creek, Loose Park, the future Plaza — was rural in 1864 and remains, in the case of Loose Park, civically protected open ground. Loose Park’s preservation as parkland is partly a function of its battlefield significance.
- Cultural complexity. Westport sits at the seam of KC’s Confederate-sympathy past (the Wornall family, the Border Ruffian history, the slaveholding farms of southern Jackson County) and its Union outcome. Modern interpretation works to hold both honestly.

Cultural memory
The battle is observed annually with a Battle of Westport reenactment weekend in October on grounds adjacent to Loose Park. The Monnett Battle of Westport Fund has operated since the early 20th century to preserve battlefield sites and historical markers.
The “Gettysburg of the West” framing is widespread in KC historical writing but contested by academic historians — the battle’s scale and political consequences were significant regionally but did not approach Gettysburg’s strategic or symbolic weight. The phrase persists locally as a marker of civic pride in Westport’s battlefield heritage.
