Captain Baston W. Cox commanding the " Johnson County Lancers", a volunteer cavalry company in the 10th Militia Regiment on June 18, 1861. I have never figured out what became of this unit.

I don't show a connection between this unit and McRea's Battalion. I am tracking that McRea's battalion origionally consisted of four companies from

Company A – of Benton County.
Company B – of Franklin County.
Company C – of Franklin County.
Company D – of Yell County.
