Stewart Sifakis (“Compendium of the Confederate Armies”), and William Shea and Earl Hess (“Pea Ridge: Civil War Campaign in the West”) seem to say it was the 22nd-that-became-the 20th, in fact Shea and Hess refer to this regiment as the “20th” at Elkhorn, even though it must have been the 22nd at the time, March ’62. Additionally, Sifakis states the 35th-that-became-the-22nd was organized June-July ’62, which would preclude it being at Elk Horn Tavern in March of that year.
I thought this pretty well settled it, until I say a photo of what was described as an Arkansas regimental flag that has “22nd Regt” on it as well as the names of battles that Sifakis says the 35th-that-became-the-22nd was in (Helena, Jenkins Ferry), so it must be the flag of that unit. But this flag also has “Elk Horn” on it! Can anyone shed any light on which 22nd Arkansas Infantry was actually at Elk Horn Tavern? Did the 35th-that-became-the-22nd have some previous incarnation before it was the 35th?
To further muddy the waters, that flag also has “Oak Hills” on it, which was fought in August ’61, but again, Sifakis states the 35th-that-became-the-22nd was organized in ‘62. It also has “Prairie Grove” on it, which Sifakis does not mention for either “22nd.” Help!
