What Dismounted Texas Cavalry units were at Pea Ridge, if any. Many of the Dismounted Texas Cavalry units passed through the Austin, Arkansas (Camp Nelson area) on their way to Des Arc for the steamboat ride to Tennessee and the too late arrival for Shiloh. The name of any one of these Dismounted Texas Cavaly units would be of a great help. So what I'm looking for is any Dismounted Texas Cavalry unit that left Pea Ridge and later caught one of the many steamboats at Des Arc for the ride to Tennessee.
