From the record
“Fort Harker, located near Stevenson, Alabama, United States, was a military fortification built by the Union Army during the American Civil War. Constructed in the summer of 1862 by soldiers and freed slaves of the Army of the Cumberland, the fort helped secure strategic railroad lines to ensure the free movement of Union troops and supplies in southeastern Tennessee and northeastern Alabama.”
