Thoroughly enjoyed this recollection of experience by a Union volunteer who joined in late 1863 and served as an artilleryman and later artillery officer. His matter of fact descriptions of Army of the Potomac life and battles as an artilleryman and as a rifleman on the battle line were educational and without glorification. The narration voice was a steady drumbeat of matter of fact’ness that conveyed this 1880’s author’s purpose and intent.
