You might want to add Camps Rust and Texas to your list. Both located just west of Little Rock. Camp Rust is where the troops congregated after the retreat from Devall's Bluff in the summer of 1862. Camp Texas had to have been close by, as members of the 26th Arkansas were required to march to Camp Texas to witness an execution on 01 Aug 1862. The next camp this regiment occupied was the Camp Crystal Hill you've listed, which was also known as Camp Northwestern.
