I have only one James in my roster, McCamish, James, Pvt., Co. H, age 18, enlisted November 16, 1861 at Riceville, Tenn., captured and paroled at Vicksburg July 4-9, 1863, absent at March 11, 1864 muster (M268 Roll 292)

Here's another thought re those "shipped with paroled sick and wounded prisoners from Vicksburg July 24, 1863 to Mobile, Ala. via New Orleans, La."
There could be a ship's manifest of those wounded. Suggest you contact the Old Court House Museum in Vicksburg and also Terry Winschel, Historian at the Vicksburg National Battlefield Park. From there we might find out how they were disposed of in Mobile, etc.
