Antietam National Battlefield

On September 17, 1862, Union and Confederate forces collided near Sharpsburg, Maryland, in the single bloodiest day in American history, with 23,000 casualties in 12 hours of savage fighting.

Battle of Antietam resulted in over 22,726 dead, wounded, or missing—more than any other single day of combat in U.S. history. Union's tactical performance at Antietam gave President Lincoln the 'victory' he needed to issue the preliminary Emancipation Proclamation. One of the first five Civil War battlefields to receive federal protection, designated in 1890.
