Some battles have more than one name; e.g., the battles known in the North as Battle of Antietam and Second Battle of Bull Run were referred to as the battles of Sharpsburg and Manassas by the South. This was because the North tended to name battles after landmarks (often rivers or bodies of water), whereas the South named battles after nearby towns.
