On September 17, 1862, after twelve hours of savage combat at Antietam, in Maryland, 23,000 soldiers were killed, wounded or missing. The National Park Service calls it “the bloodiest single-day battle in American history.” Clara Barton had no official job title there, and she had never attended nursing school; the nursing care she gave was self-taught. She watched harried surgeons dress the soldiers’ wounds with corn husks, and she handed over to them a wagon load of bandages and other medical supplies that she had personally collected over the past year.
As bullets whizzed overhead and artillery boomed in the distance, she cradled the heads of suffering soldiers. As she knelt down to give one man a drink, she felt her sleeve quiver. She looked down and saw a bullet hole in it, and then she discovered that the bullet had killed the man she was helping.
Working non-stop until dark, she comforted the men and assisted the surgeons. When night fell, the surgeons were stymied again, this time by lack of light, and she produced lanterns from her wagon of supplies, so that the thankful doctors could go back to work. After Antietam, Brigade Surgeon James L. Dunn wrote that Gen. McClellan, “with all his laurels, sinks into insignificance beside the true heroine of the age, the angel of the battlefield.”
After the war her Missing Soldiers Office, in four years, received 63,182 inquiries and, in the words of her final report to Congress, “identified 22,000 men.” In August 1865 she and Dorence Atwater brought back relics from Andersonville Prison. On May 21, 1881, she founded the American Red Cross, and she led it for twenty-three years. Her account of the bullet at Antietam ends: “I have never mended that hole in my sleeve.”

The facts and where they come from
- She was holding a wounded soldier, but a bullet went through her sleeve and killed him. Clara Barton Museum: “She held another wounded man in her arms and as she helped him take a drink of water from a canteen, a bullet passed through her dress sleeve killing her patient instantly.” National Park Service: “As she knelt down to give one man a drink, she felt her sleeve quiver. She looked down, noticed a bullet hole in her sleeve, and then discovered that the bullet had killed the man she was helping.” 51

Notes
Where the nickname began: the National Park Service’s biography says the surgeon at Cedar Mountain (August 1862) “later likened her to an angel”; the phrase “the angel of the battlefield” itself is in Dr. Dunn’s letter, written after Antietam. We say only that a surgeon called her that.
Her account of the bullet: its wording differs between versions (“A ball has passed … cutting through his chest” at the National Park Service and the Antietam Institute; “had passed … cutting through the sleeve, and passing through his chest” in other retellings), so we quote only its last sentence, which is the same everywhere.
When and where she arrived: about noon at the northern edge of the Cornfield (National Park Service) or about 9 a.m. at Samuel Poffenberger’s farm (Clara Barton Museum). We give neither.
22,000: her final report says “identified 22,000 men”; Wikipedia says “more than 22,000”; the American Red Cross says “more than 20,000.” We say about 22,000.
Left out for length: she cut a bullet from a soldier’s cheek with a pocketknife (Clara Barton Museum), cooked gruel, and days later collapsed with typhoid fever (National Park Service).
Pictures: Clara Barton herself is in Mathew Brady’s portrait of about 1865, the Brady studio portrait, the halftone of the Civil War portrait she authorized “as the one she wished to be remembered by” (about 1890) and the cabinet card with her Red Cross brooch (the Library of Congress dates the photo about 1865; she inscribed the card in 1894). The paintings of 1887 and 1888 show the battle, not Barton. Alexander Gardner’s photos of Dr. Hurd’s field hospital and Smith’s barn show Antietam field hospitals after the battle, not the place she worked, and his army forge with wagons isn’t her wagon. The Andersonville relics are the ones she and Dorence Atwater brought back in 1865; John L. Ransom’s lithograph of 1882 shows the prison.
