This is somewhat off topic, but it does relate to the 11th and 17th Arkansas. Found these two messages in the digitized Confederate records now being produced by the National Archives.

RG 109, Ch 1 Vol 44 letters and telegrams sent Jan-April 1865

3/14/65 Richmond AG's office to Gen Richard Taylor-In reply to the request of Col Jno Griffith for the transfer of 3 Co's of Lay's regt to the 11th & 17th Ark regts, these Co's are not known to the Dept as legal organizations
Nothing can be done until the official returns have been rec'd here, the rolls being incomplete and the information in Col Griffith's letter is so unsatisfactory that action by the Dept under it would only create confusion

3/18/65 Gen Cooper to Kirby Smith-It appears from papers on file in this office that a portion of the 11th Ark regt is serving in your Dept under the command of Col Logan.
The Sec directs that these men be ordered to report to Gen Hayes to be crossed to the Regt formed from the consolidation of the 17th & 11th Ark Regts and now serving east of the Ms River.
