The Gaines/McNally battery was organized as the "John D. Adams Artillery," or usually just "Adams Artillery". When the battery was captured at Vicksburg, a section of two 3-inch brass rifle guns under First Lieut. Frank A. Moore had been on detached service outside the Vicksburg lines and thus escaped capture. However, when McNally's Battery was exchanged back in Arkansas, Moore's section was stranded east of the Mississippi. It was subsequently attached to King's 2nd Missouri Battery and served east of the Mississippi to the end of the war. Unfortunately, there are no known surviving muster rolls of the Adams Artillery.
