With the formal Emancipation Proclamation of January 1, 1863, the war took on new purpose. In the North, and in many foreign lands, the cause of American Union had become one with that of human liberty.

Clara Barton at Antietam

At Antietam, also, was Clara Barton, founder of the American Red Cross. On this field of desolation, long after the guns had ceased, Miss Barton was still busily rendering care to the wounded and dying. Having arrived early in the day in the northern area of battle, she witnessed the wounded men of Sedgwick’s depleted ranks streaming to the cover of North and East Woods. By midmorning her wagonload of supplies, donated by the citizens of Washington, had arrived. She worked tirelessly with army surgeons at the field hospital on the Joseph Poffenberger farm. Her supply of bandages, linens, anesthetics, and oil lanterns replenished the surgeons’ urgent need of dressings and provided light to carry on through the night. So outstanding were her services on the field of battle that she later received official recognition by the United States Army Medical Corps. Her work here and later would become basic to the establishment of the American Red Cross.

Antietam National Battlefield and Cemetery

The Antietam National Battlefield was established August 30, 1890, to commemorate the significant events of September 17, 1862, and to preserve the important features of the battlefield. Administered by the War Department until 1933, the site was transferred that year to the U.S. Department of the Interior to be administered by the National Park Service.
