I can't help you with the information you seek except to mention that this battery was officially the 10th Battery, Texas Light Artillery, commanded by Captain J. H. Pratt. Formed very late 1862 or early 1863. In the summer of 1864, Captain S. S. Hynson became the commander of this battery. You may already know this but if not, it will help you by researching Hynson's battery and the 10th Texas Battery.
