William Pratt Parks, of Little Rock, was the original second lieutenant of the Magruder Guards, later promoted to first lieutenant and captain. He was captured at Vicksburg.

The 1st Tennessee Heavy Artillery Regiment was organized at Fort Pillow on May 10, 1862, after the capture of Island No. 10. The regiment embarked on steamer Golden Age on June 2, 1862, bound for Vicksburg. Upon arrival at Vicksburg, it was consolidated by order of Brig. Gen. M. L. Smith on June 18, 1862. I don't know the official reason for this consolidation, but I suspect that it was due to the depleted numbers -- there were only about 330 men at the time. The final consolidation ordered by Maj. Gen. D. H. Maury on February 4, 1864, was due to the fact that the men were scattered all over the place after being paroled at Vicksburg -- "A number of the men, after being furloughed when paroled, joined the cavalry in North Mississippi and West Tennessee, and are now on duty with General Forrest's Command. Every effort to have these men returned to the regiment has failed."

By the way, have you included the Arkansas companies attached to the 40th Tennessee Infantry in your tally? I can't remember if we discuss this before or not, but I've had a lot of "senior moments" lately.
