The Medal of Honor was created during the American Civil War and is the highest military decoration presented by the United States government to a member of its armed forces. The recipient must have distinguished themselves at the risk of their own life above and beyond the call of duty in action against an enemy of the United States. Due to the nature of this medal, it is commonly presented posthumously. The first Army Medal of Honor was awarded to Private Jacob Parrott during the American Civil War for his role in the Great Locomotive Chase.
