Records for Robert S. German (also spelled Jerman), Co. K, 63 Alabama Infantry (2nd Alabama Reserves), indicate that he enlisted in Coosa County on Oct. 8, 1864. It is likely that he was a conscript. You don't mention his age, but in 1864, most of these soon-to-be men were still boys between the ages of 16 and 18. This site will give you a sketch of the regiment and where they served:

A medical card in his file states that from March 3, 1865, to April 4, 1865, he was hospitalized for debilitas at the 1st Mississippi CSA Hospital. The card states that the hospital is in Jackson, Mississippi, but, in fact, the hospital by that time had been relocated to Shelby Springs, Alabama. It is likely he was transported there by rail. The only other card in his file covers his parole. He was paroled June 3, 1865, at Talladega. Although the parole records state that the parolees were prisoners of war, in fact, they were not "captured" in the sense that they laid down arms and surrendered. As a part of the Department of Alabama, Mississippi, and East Louisiana, they were surrendered by General Richard Taylor at Citronelle, Alabama, on May 4. Taylor and a couple of aides were the only Confederates present there, as the department was scattered in many locations. Orders went out from Taylor to his command to report for parole at various locations designated by the Union authorities. One of these places was Talladega. I suspect that German did not or could not travel to Blakeley to attempt to rejoin his unit prior to its capture on April 9, just five days after he was discharged from the hospital. My best guess is that he went home, and later, as instructed, reported to Talladega to receive his parole.
