Battles of the American Civil War were fought between April 12, 1861, and May 12–13, 1865 in 19 states, mostly Confederate (Alabama, Arkansas, Florida, Georgia, Kansas, Kentucky, Louisiana, Maryland, Mississippi, Missouri, North Carolina, Ohio, Pennsylvania, South Carolina, Tennessee, Texas, Vermont, Virginia, and West Virginia[A]), the District of Columbia, and six territories (Arizona Territory (also Confederate Arizona)[B], Colorado Territory, Dakota Territory, Indian Territory (present-day Oklahoma), New Mexico Territory, and Washington Territory), as well as naval engagements. Virginia in particular was the site of many major and decisive battles. These battles would change the standing and historical memory of the United States.
For lists of battles organized by campaign and theater, see the list below:
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 Battle of Sharpsburg and the Battle of Manassas, respectively, 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.
The American Battlefield Protection Program (ABPP) was established within the United States National Park Service to classify the preservation status of historic battlefield land. In 1993, the Civil War Sites Advisory Commission (CWSAC) reported to Congress and the ABPP on their extensive analysis of significant battles and battlefields. Of the estimated 8,000 occasions in which hostilities occurred in the American Civil War, this table and related articles describe the 384 battles that were classified in CWSAC's Report on the Nation's Civil War Battlefields. In addition to the status of battlefield land preservation (not included in this table) CWSAC rated the military significance of the battles into four classes, as follows:[1][2]
