Lower Seaboard Theater of the American Civil War

The Lower Seaboard Theater of the American Civil War encompassed major military and naval operations that occurred near the coastal areas of the Southeastern United States (in  Alabama, Florida, Louisiana, Mississippi, South Carolina, and Texas) as well as southern part of the Mississippi River (Port Hudson and south). Inland operations are included in the Western Theater or Trans-Mississippi Theater, depending on whether they were east or west of the Mississippi River. Coastal operations in Georgia, as the culmination of Sherman's March to the Sea, are included in the Western Theater.
