The purpose of this legislation is to honor James J. Andrews and William H. Campbell by awarding them the Congressional Gold Medal posthumously. This recognition is for their exceptional bravery and commitment to the United States during the Civil War, specifically for their roles as the only civilian members of Andrews' Raiders, who conducted a significant military operation known as the "Great Locomotive Chase." The key provisions of this legislation include the authorization for the presentation of a single gold medal to commemorate Andrews and Campbell.
