A "youth" enlists in the Union Army during the American Civil War with visions of glory in his mind, but he runs away like a coward in the first skirmish. As he moves as far as he can from the battlefield, he encounters wounded men headed toward the hospital. He hears their stories of courage, noting that they wear a "red badge" of their own blood. He is ashamed but finds ways to excuse his behavior in his own mind. He has an altercation with a fellow soldier, who gives him a minor wound on his head. At last he finds his way back to his own regiment, joining them again, pretending that he got his wound in battle. The next day when the regiment begins to move forward into battle again, the youth wonders if he will have the courage to stand and fight this second time.
