Union Military Organisations: Capital and North-Eastern Theatre

Union Military Organisations: Capital and North-Eastern Theatre

Go to Western Territories and Pacific Coast Theatre / Pacific Coast Theatre / Trans-Mississippi, Northwest, and Frontier Theatres / Western Theatre / Gulf Coast Theatre / Eastern Theatre / Atlantic Coast Theatre for detailed summaries.

This theatre broadly covers the northeastern states of Connecticut, Maine, Massachusetts, New Hampshire, New York, New Jersey, Rhode Island, and Vermont, along with the territorial commands around the District of Columbia in Maryland, Delaware, and Pennsylvania.
The New England states saw few active operations on their soil but were nevertheless important in maritime and recruiting activities. Where military activity did impinge on their territory in Pennsylvania, Delaware, Maryland, and around the capital district, they were generally assigned to an appropriate territorial command.
