Dale, I've been tied up with other things, so I'm now trying to get caught up on the message board. I can't help you a whole lot with McNally's Battery -- there aren't a whole lot of records available for this company. However, I can give you a brief overview. McNally's Battery began as the "John D. Adams Artillery", or "Adams Artillery" for short. From what I can tell, it seems to have been initially organized and recruited at Little Rock. It was mustered into State service in April 1861, and became known as Gaines' Arkansas Battery (Capt. James J. Gaines commanding). It was mustered into Confederate service in December 1861 for twelve months service. It was reorganized at Corinth, Mississippi, on May 16, 1862, and re-mustered into Confederate service for three years or the war. Capt. Francis M. McNally assumed command, and it was thereafter known as McNally's Arkansas Battery. The battery surrendered at Vicksburg on July 4, 1863, and was exchanged near Washington, Arkansas, in November 1863. McNally's Battery remained in the Trans-Mississippi Department for the rest of the war. It was redesignated as the 1st Arkansas Field Battery on November 19, 1864. When the Trans-Mississippi Army surrendered in May 1865, McNally's Battery, along with most other units, disbanded and never formally surrendered.
There isn't a complete enough list of men to make anything other than a general remark that the initial members were mostly from Pulaski County and vicinity, and that subsequent recruits and conscripts came from all over the State. Later officers, for example, were from Washington and Helena, opposite sides of the State. I'm afraid that's the best I can do. Hope this helps a little.
