I also have the 77th Illinois and 99th Illinois. I am still stuck on what flag the 27th LA captured on May 19th, 1863. A total of five flags were captured. I remember either you or somebody else typed it could be a Union Missouri Flag. Only BG. Ewing's brigade and BG. G.A. Smith attacked.
We will get them figured out!
Have a good day and great job on the 130th Illinois, that was a tough one!!
