The American Battlefield Protection Program (ABPP) and the Civil War Sites Advisory Commission (CWSAC) maintains a list of Civil War battles in the United States by individual state, including Missouri, Arkansas, Kansas and the Indian Territory (Oklahoma). Interactive maps of each state show the location of each battle or skirmish, and viewers may click on the name to produce general information about each battle.

Dyer's Compendium of the War of the Rebellion lists major engagements by state and date, and the Official Records of the War of the Rebellion, known as the “O.R.”, also has a comprehensive index of engagements by location, name of battle, name of unit, etc.
