Battle of Marmiton River: The Last Day of Price's Raid

On October twenty-fifth, eighteen sixty-four, this river crossing in Vernon County, Missouri witnessed the final unraveling of one of the Confederacy's most ambitious western campaigns.

Major General Sterling Price, known as Old Pap, had led a force of twelve thousand men north into Missouri in September eighteen sixty-four, hoping to seize the state capital, rally pro-Confederate Missourians, and perhaps shift the balance of the war in the Trans-Mississippi theater. Instead, the expedition became an extended catastrophe. Price was defeated at the Battle of Westport, outside Kansas City, on October twenty-third, the largest battle ever fought in Missouri. The survivors began a desperate retreat southward.

October twenty-fifth became a day of cascading disasters. At dawn, Price's column was struck at the Marais des Cygnes River. By mid-morning, at Mine Creek in Kansas, two Union brigades of roughly twenty-five hundred men shattered a Confederate force of seven thousand in what became the largest cavalry engagement of the entire war in the western theater. Two Confederate generals were captured. More than a thousand Southern soldiers became casualties.

By late afternoon Price's battered wagon train had reached the crossing of the Marmaton River here in Vernon County, just across the Kansas line. Brigadier General John McNeil's Union cavalry caught the rear of the column. The Union horses were too worn out from the day's fighting for a full charge, so McNeil's troopers harassed the retreating column rather than pressing a full assault, but the skirmish pushed Price's column across and southward again. He would be defeated once more at Newtonia four days later before the survivors limped into Texas in early December, having traveled more than fourteen hundred miles and accomplished none of their strategic objectives.

The river today looks quiet. But in the span of a single October afternoon in eighteen sixty-four, three separate engagements within a few miles of one another sealed the fate of the Confederacy west of the Mississippi River.
