During the Civil War, Clara Barton--one of the first women to receive permission to serve on a battlefield--snuck her supply wagon to the head of a ten-mile wagon train to deliver provisions to the Antietam Battlefield. On the bloodiest day in American history, Clara and her team of helpers sprang into action as they nursed the wounded and dying, cooked meals for soldiers, and provided doctors with desperately needed medical supplies and lanterns so they could operate through the night.

Author Claudia Friddell blends her words with Clara Barton's firsthand account to capture the nurse's brave actions, while Christopher Cyr's dramatically accurate illustrations portray one of the most heroic women in history.
