Here are my sources: Peter Cozzens "This Terrible Sound" page 186 and 187, describes the action.
"Recaptured Union Flags" "Congressional edition Volume 2558" By the United States Congress.

"Regimental flag of the Thirtieth Indiana Volunteers captured by LT. Meade, of Sharp-Shooters, Polk's Corps, battle of Chickamauga."
I tried looking on the National Archives soldiers and sailors website with his name, but nothing came up. But he was 110% in the 24th Tenn SS and BG. Maney's brigade was all Tennessee. In Peter Cozzens book, "2:30 p.m. Brock Field" Pages 184-185, Maps.
Hope that helps!
