My direct paternal and maternal gg grandfathers were both captured during the war. I am wondering if someone can help me fill in the blanks on some of their details.

Cornelius Shows (Neal) from , AL was my maternal gg Grandfather. He was assigned to the 59th Alabama Infantry. So far I have:
Census or Enumeration of Confederate Soldiers Residing in Alabama, 1907
No.212, lists Cornelius Shows , Rutledge, Al was born on March 1, 1842 at
Salsoda, Butler County, Alabama. First entered the service as private,
Spring, 1862 at Greenville, Alabama in the 59th Alabama and continued
until paroled at Point Lookout at the close of the war. Pay warrents for
Cornelius Shows show that he was a private in the 4th Battalion (Art'y),
Capt. Glasgow's company, Hilliard's Legion, Alabama Volunteers. Joined
at Greenville, Ala. April 10, 1862 at age 24 years by J.R. Glasgow for
three years. At the end of the war, he is shown as a private in the 59th
Alabama Regiment. He swore the Oath of Allegiance at Point Lookout, Md.
on June 17, 1865. It reports that he was from Butler Co., Alabama, had a
light complexion, Dark Brown Hair, Gray eyes and was 5 ft. 81/8 inches
tall. He signed the oath by "mark".
Family history has his name was Cornelius "Neal" Shows. It is said that
he was wounded in the hip at the battle of Lookout Mountain, Tenn. and
spent the remainder of the war as a prisoner of war. He was paroled
without even shoes on his feet and had to walk with others back to
Alabama. He is said to have survived on anything he could find along the
way....Even eating corn from horse dropping.
The record indicates that he was indeed at Point Lookout but that was in
Maryland. Confererate prisoners who were paroled were usually sent south
by train.
I would like to confirm his wounding at Lookout Mountain and his internment at Point Lookout. I cannot find his prison records at all.

Secondly, my paternal gg grandfather, H.R. Gorum (sometimes spelled Gorom) was assigned to Company K, Fifth Alabama Regiment. Family history says he was captured at Chancellorsville. I would like to confirm that and find out what I can about his internment.

Can anyone lend a hand?

Thank you, Chuck
