Damon,
Not sure if you have these already...
Fold3 lists Captain John J. Hall and 2nd Lieut. John L. Henry both of Company G, Flippin's Battalion and 1st Lieut. E. Sandusky of Company F(?).
(listed under Miscellaneous Arkansas).
An online search suggests a Capt. John G. Mastain as commanding Company C.
