I have a reprint of THE HELENA VICTORY news clip reprinted from the Missouri Democrat 05 Jul 1863 listing both Sgt. Shale and Greenbury Mattox as killed.
My 2nd great grandfather, Thomas A. Moore, was pronounced mortally wounded with a gun shot wound to the right temple at the same battle.
If you're interested in the article or your ancestors were from the St. Louis or Madison/St. Clair Co., IL areas I have a website honoring those veterans.
