George N. Barnard was one of several unacknowledged photographers who worked for Civil War photographer Matthew Brady before setting out on his own in 1863. Serving as official photographer for the Army of the Cumberland’s topographical branch of the Department of Engineers, Barnard documented notable battlefields, military works, bridges, and topographic views. His best-known works are his striking images documenting Sherman’s march to the sea. Sixty-one albumen plates from this project were published by Barnard in 1866 as an album titled "Photographic Views of Sherman’s Campaign".
