I came across this brief article in the Sangamon Journal/Illinois State Journal dated 23 August 1862 and thought it may be of interest to someone:

Springfield, Mo., August 22---
Col. Wright, of the Federal forces, passed Carthage yesterday in hot pursuit of the guerrillas of Coffee, Hays and Quantrill.
On Wednesday, he attacked the Rebels' rear guard, killed two, and captured 31 horses.
Quite a number of guns, horses and other property, had fallen into his hands.
The Kansas troops, under Gen. Blunt, were only a few miles behind, pushing on rapidly.
A number of horses and a quantity of camp equipage were found at the Osage, where the rebels crossed.
All the bad characters in western Missouri are joining Coffee, which will drain that section of a dangerous element.
The pursuit will not be relaxed until the rebels are driven from the State.
