US War Department - War of the Rebellion (Series II, Volume VII, pgs. 796 - 976, duplicates).

Abstract

"My view of the matter is that we had better send off disabled men and those whose term of service has expired to the extent of the remaining unexchanged Vicksburg men. I doubt the policy of going further. The Yankees will force the men whose term of service has unexpired into the field, regardless of any parole which they may give."
