On ancestry.com there are documents about bodies removed to each of the National Cemeteries. In the one on bodies moved to Little Rock National Cemetery, it lists 17 bodies being received at the cemetery from Austin on August 1, 1868 but doesn't mention who they were. The same entry is in the Devall's Bluff notes. I'll note that the DB book isn't just DB...it includes places in NE Arkansas, places along the White River and some of the Camden Expedition sites.
