I am working through the list of Arkansas Infantry Battalions. I haven't found that there was ever a 5th or 6th Battalion. I don't include Borland Battalion in this list since it was really a militia organization. Here is what I have so far:

1st Arkansas Infantry Battalion, became 18th (Marmaduke's) Arkansas Infantry Regiment/3rd Confederate Infantry Regiment
2nd Arkansas Infantry Battalion, eventually merged with 3rd Arkansas Infantry Regiment
3rd Arkansas Infantry Battalion, eventually became the 15th (Northwest) Arkansas Infantry Regiment
4th Arkansas Infantry Battalion eventually consolidated with the 4th Arkansas Infantry Regiment
7th Arkansas Infantry Battalion, eventually consolidated with 8th Arkansas Infantry Regiment
8th Arkansas Infantry Battalion
9th Arkansas Infantry Battalion, eventually consolidated with 8th Arkansas Infantry Regiment
11th Arkansas Infantry Battalion, eventually enrolled in the 25th Arkansas Infantry Regiment
12th (Sharp Shooters) Arkansas Infantry Battalion
Williamson's Arkansas Infantry Battalion, split up, with companies going to several Arkansas units near Corinth Mississippi
Crawford's Arkansas Infantry Battalion

Any thoughts>
