On January 10, some of Porter's men raided other Union installations in the area before making contact with Marmaduke's column east of Marshfield.
Early on the morning of January 11 the approaching Confederates under Porter made contact with Merrill's scouts and skirmishing commenced.
Meanwhile, observing this movement, Merrill marched his force directly to Hartville where it took a strong defensive position on covered, high ground west of the courthouse.
A mistaken observation probably by Lt. Dick Collins on the bluff east of town reported a wagon train moving toward the Lebanon Road.
From the Union command's perspective they had repulsed Marmaduke's assaults inflicting heavy casualties, but the Federals had been forced to leave the field.
Additionally, the frontal assaults had resulted in the death or mortal wounding of several senior CSA officers including: brigade commander Col. Joseph C. Porter, Col. Emmett MacDonald, Lt. Col. John Wimer, and Major George R.
[9] The raid itself caused great disruption of Federal forces in the region and a number of small outposts had been overrun, destroyed, or abandoned.
