Hi Ernest -
the URL link below will take you to a history of the 11th/17th Arkansas Infantry. The listings for Natchez (Dec. 1863) and earlier actions like Catlett's (Oct. 1863) might help you out.
I notice that the units under Wirt Adams at Catlett's in Oct. 1863 included a certain 9th Louisiana Battalion -- is this the same unit or related to Miles Legion perhaps????
Am curious to hear what you find out; please keep in touch?
y.v.o.s.,
Kenneth Byrd
