The Battle of Marmiton River, also known as Shiloh Creek or Charlot's Farm,[1]: 80  occurred on October 25, 1864, in Vernon County, Missouri during the American Civil War.

Price was again defeated on October 28 at the Second Battle of Newtonia, and the Confederate retreat continued until the survivors reached Texas in early December.

After being repulsed at the Battle of Pilot Knob in late September, Price's army changed course to aim for the Missouri River.

The Union Army of the Border began pursuing Price's column, and defeated the Confederates at the Battle of Westport near Kansas City on October 23.

Brigadier General Joseph O. Shelby's division arrived in time to provide Price's column with a rear guard after Mine Creek.

Union cavalry would eventually brush aside the Confederates at the Little Osage River, but the defense had bought time for Price's retreat.

The front of the line consisted of militia officer M. Jeff Thompson's brigade of Shelby's division, some of the remains of Major General James F. Fagan and Marmaduke's (commanded by Brigadier General John B. Clark Jr. after Marmaduke's capture) divisions, which had been shattered at Mine Creek, and a portion of Colonel Charles H. Tyler's brigade.

[6] Union cavalry commanded by Brigadier General John McNeil and Lieutenant Colonel Frederick W. Benteen caught up to Price's makeshift line.

After the arrival of the Union forces, Shelby ordered the portion of Tyler's brigade on the front line to charge, but this attack was quickly repulsed by McNeil's men.

At this point, the Confederate army was so shattered that historian Albert E. Castel described the force as essentially an armed mob.
