The other three companies mentioned above spent approximately two months serving together as cavalry in Gipson's Battalion Mounted Rifles.

Sharpshooters were equipped in the same manner as infantry, with the standard rifle or rifle-musket; some were even armed for a time with smoothbore weapons.

The term "battalion" implies that the unit was organized with fewer than the full ten companies required for a regiment.

The casualty list of this unit at Prairie Grove did survive as it was published in the True Democrat newspaper in Little Rock on December 31, 1862.

Their primary role was serving as an infantry battalion alongside Hawthorn's Regiment during the fighting at Prairie Grove.

In that role, they took part in the charges of Fagan's Brigade driving back the 20th Wisconsin, 19th Iowa, and 37th Illinois and 26th Indiana regiments when these Union troops ascended the ridge.

A query in the Confederate Veteran magazine by Chew's nephew stated that his uncle belonged to a Tennessee regiment and was killed at Prairie Grove.

The nephew said he was told that his uncle's sword and watch had been recovered from his body and was hoping these items could be reunited with the family.

Chew had, in fact, served as a captain in Company H, 2nd Tennessee Infantry (Col. J. Knox Walker commanding).

Apparently through Arkansas connections, he managed to get transferred back across the river to serve as a staff officer for Gen. Thomas C. Hindman.

Sometime in October November, 1862 Robert Chew received a promotion to major and was given the assignment of commanding his own sharpshooter battalion.

Adding up the numbers in the casualty list that appeared in the True Democrat, Chew's Battalion went into action with 12 officers and 104 enlisted men.
