I have been adding my family's CSA soldiers, and even a few others not related from Arkansas, especially Union County. When I added CSA records for a couple of boys I had listed sometime ago, Thomas Teague and John Teague, brothers, who served in the Johnson's (SW) 15th Arkansas Infantry Co D, were captured at the Battle of Ft Donelson, Tennessee and sent to Camp Butler, where they died within months of each other.

No matter how anyone feels about the South, the Civil War, or the War of Northern Aggression, or even slavery, these boys fought and died for what they believed in. The Teagues 1850 and 1860 Union Co AR were not slave owners. But they fought and died for the South.
