I would conclude that Bill served with his company continuously from the date of his enlistment until captured near the Big Black River, Miss. around the 1st few days of July, 1863. He was held prisoner in Vicksburg until paroled on July 12, 1863. Thereafter he made his way back to his regiment sometime later. Muster rolls for his company have not survived for the period July 1863 through June 1864, and then no further rolls. Hence, we are not able to trace his travels. None-the-less, he sometime later was able to rejoin his unit and remained through the end of the war when his command was surrendered to Federal forces.

** There were a a number of savage little fights in that area [Big Black River Bridge] during the first two weeks of June, as the Confederate cavalry [Johnston's Second Front] tried to push the Federals back across the stream. In addition, Gen. Johnston conducted a number of patrols in the area July 1-4. [Ninety-Eight Day, A Geographer's View of the Vicksburg Campaign, Warren E. Grabau, U. of Tenn.
