On another note, I was looking through Wiley Sword's "The Confederacy's Last Hurrah" book and page 195 had this.
"Boys, we have got to get out of here." A corporal glanced up and saw the regimental colors going back."
So now that makes me think the National Flag of the 50th Ohio was left behind. Nobody on either side claimed to have found that flag. I am going to leave that in the question mark file, till I find 110% positive proof it was captured.
Have a good night.
