Thanks very much, Danny, for all this detailed information on the last two months of his life. Rock Champion seems to have been the beau ideal of a Southern cavalry officer.
I don't know that I will ever be able to prove that Beroth B. Eggleston, who was captured at Courtland was the one who offended the Belle of Courtland, but he seems to be the ranking cavalry officer in the engagement, and he became a colonel soon after his parole. Some of the versions of the story say the cavalry officer surrendered his sword to Champion and was taken prisoner by him, instead of being killed by Champion. All of the stories, and there are four or more, indicate the man was cavalry, not infantry. Eggleston's character came out when he went to Mississippi after the war and became Carpetbagger #1. As presiding officer of the Black and Tan Constitutional Convention, he lined his pockets with the state's money, soon becoming one of the most hated men in Mississippi. He ended up being called "Brindle Buzzard" Eggleston before he returned north.
I am working on finding where he was buried. I have found a few clues, but am not there yet.
Thanks again for taking your time to put together all this good information.
