Sorry to be short on the uptake, so are we saying that Clarkson's Battalion mentioned in the post that I found below is the same as Buster's 15th Arkansas Cav Battalion and the names listed as 13th Arkansas Cavarly Regiment in the CSRs actually belonged to Clarkson/Buster's unit?

Clarkson's Cavalry Battalion Independent Rangers [also called the Indian Battalion] was assembled during the winter of 1861-1862 with Missouri and Arkansas companies. The unit operated in the Indian Territory and took an active part in the conflicts at Newtonia and Granby. In November, 1862, it merged into the 9th (Clark's) Missouri Infantry Regiment. Its commanders were James J. Clarkson, Lieutenant Colonel M.W. Buster, and Major J.Quin Morton.
