Damon, prior to the consolidation of the Arkansas regiments in the Army of Tennessee in April 1865 -- 1st Arkansas Consolidated Infantry and 1st Arkansas Consolidated Mounted Rifles -- there was another mass consolidation of Arkansas regiments in the Trans-Mississippi Army. In September 1864 the following consolidated regiments were formed:

1st Arkansas Consolidated Infantry—Col. Jordan E. Cravens.
14th Arkansas Infantry.
15th (Northwest) Arkansas Infantry.
16th Arkansas Infantry.
21st Arkansas Infantry.

2nd Arkansas Consolidated Infantry—Col. Thomas J. Reid, Jr.
12th Arkansas Infantry.
18th Arkansas Infantry.
23rd Arkansas Infantry.
8th Arkansas Battalion.
12th Arkansas Battalion.

3rd Arkansas Consolidated Infantry—Col. H.G. P. Williams.
15th (Gee/Johnson) Arkansas Infantry.
19th (Hardy’s) Arkansas Infantry.
20th Arkansas Infantry.

All of these regiments, except for Hardy's, had been captured at Vicksburg and Port Hudson and exchanged back in Arkansas. Hardy's regiment, of course, consisted of those members of the 19th and 24th Arkansas Regiments which had avoided capture at Arkansas Post.

These three consolidated regiments constituted the 2nd (McNair’s) Arkansas Brigade, 1st (Churchill’s) Arkansas Division, 2nd Corps, Trans-Mississippi Department, from September 1864 to May 1865.
