In Defense of the Flag: A true war story / A pen picture of scenes and incidents during the great rebellion.--Thrilling experiences during escape from southern prisons, etc.

The author, who enlisted as a teenager in an infantry regiment, recounts his Civil War service, describing combat at Antietam, Fredericksburg, Chancellorsville, Mine Run and the Wilderness, injuries sustained, treatment in Washington hospitals, and the death of his younger brother from wounds. He records daily camp life, construction of rifle pits, harrowing retreats, the sight of battlefield corpses and skeletal remains, capture and imprisonment in Southern prisons and dramatic escapes, and encounters with medical staff and chaplains who comfort the dying. The narrative blends action, personal loss, and reflections on duty, suffering, and faith amid the chaos of war.
