CAMP MORTON,in pow sIMEON d. hOPKINS 1864-1865

My gggfather, Pvt. Simeon D. Hopkins was enlisted in;
Capt. White G. Ryan's Co I., Sixtieth Regiment, VA Infantry,CSA.
Captured at New Hope, VA in April 1864, he was taken to Camp Morton, IN until 1865.
I am searching for sources, internet links that will lead me to his military records during 1864-1865.
Any help or assistance will be greatly appreciated.
