George,
The information that I have on Pittman is as follows:
Private Thomas J. Pittman, 18 YOA upon enlistment at Mt. Lebanon, La. Wounded in Action at Battle of Fredericksburg on Dec. 13, 1862. Present at surrender and paroled at Appomattox on April 9, 1865. Discribed as 5'7, gray eyes, dark hair, light complexion.
Hope this is of some help.
