Most Confederate POWs, at least those at Point Lookout, Maryland, were given transportation to their geographical area by the Feds. If they were lucky to live within close distance to a working railroad they didn't have to walk far. I traced one Confederate POW who with a group of others was given transport by ship, then by railroad to Ohio, then riverboat to Vicksburg, MS., then railroad to Hazelhurst, MS., then by wagon to Westville, then carriage to Hebron. I know there were those who didn't get that treatment for reasons unknown, but not all were treated the same. I've also traced the paths of wounded Confederate soldiers on 60 furlough who walked from Enterprise, MS. to Woodville, MS. without aid of horse or wagon and walked back again. These were some tough young men.
