# Civil War Defenses of Washington

The Civil War Defenses of Washington were a group of Union Army fortifications that protected the federal capital city, Washington, D.C., from invasion by the Confederate States Army during the American Civil War.
Some of these fortifications are part of a grouping of properties now managed by the National Park Service (NPS) and listed on the National Register of Historic Places. Others are parts of state, county, or city parks or are located on privately owned properties. A trail connecting the sites is part of the Potomac Heritage Trail.
Parts of the earthworks of some such fortifications still exist; others have been demolished. A 19.5-mile long trail connecting some of the forts was designated as a National Recreation Trail in 1971.

## History
### Civil War

* An 1867 map of U.S. military installations in present-day Delaware Maryland, Northern Virginia, and southeastern Pennsylvania designed to protect the federal capital of Washington, D.C.
* An 1867 map of U.S. military installations east of the federal capital of Washington, D.C.
* General map of the defenses of Washington, D.C. from the History of the American Civil War.
During the American Civil War, Union forces built in the Washington, D.C. area, included 68 major enclosed forts used to house soldiers and store artillery and other supplies. They also built 93 prepared but unarmed batteries for field guns and seven blockhouses. There were also 20 miles of rifle pits and 30 miles of connecting military roads. The Confederacy never captured any of these forts, though some came under enemy fire.
Most were built on the limits of the city, which had remained relatively rural. Most of the land was privately owned and taken over by the military at the beginning of the Civil War.
Some examples include:
* Fort Slemmer: A 24-acre plot was owned by Henry Douglas, a florist. Flowers, 1,970 fruit trees, vines, bushes, and other plants were destroyed to complete the fort. This made the land owner unable to work in this trade.
* Fort Reno: The land belonged to Giles and Miles Dyer. The farmhouse was used by the Army as the headquarters for various commands encamped in the area. The fortification covered 20 acres of land. Some 50 more acres were used for barracks, camps, and a parade ground.
* Forts Chaplin and Craven: These forts were built on land belonging to Selby B. Scaggs. He owned a farm there totaling about 400 acres and worth $52,000. Four laborers also lived there. According to the 1860 Census Slave Schedule, Scaggs was also an enslaver of 16 people.
* Fort DeRussy: The fort was built on land owned by Bernard S. Swart, a clerk. He lived there with his wife, three children and two farmhands. Today his land is part of Rock Creek Park.
* Fort DuPont: The fort was built on the land owned by 60-year-old Michael Caton, worth $5,000 in 1860. He lived there with his wife, five children (aged 18 to 30), and one domestic worker.
* Fort Slocum: The fort was in part built on the land owned by John F. Callan, also a clerk. He lived there with his wife and their eight children (aged 8 to 24).
* Fort Bayard: The fort was built on land belonging to a farmer named Philip J. Buckey, who lived there with his wife, four children and two servants.
* Battery Kemble and part of Fort Gaines: The land was owned by William A.T. Maddox, a U.S. Marine Corps captain stationed in Philadelphia.
* Fort Stevens: The land belonged to Emory Methodist Church. Some land may have belonged to Elizabeth Thomas, a free black woman. Her house was demolished in the process. Documentation for her ownership was never discovered but the story has become part of the local folklore.
The forts in the District of Columbia were temporary structures. They were in most part built of earthen embankments, timber with limited masonry and were surrounded by trenches and flanked with abatis. They were not designed to serve beyond the Civil War as the land was intended to be returned to its owners at that time.
Most of these owners lost possession of their land for the duration of the war and were unable to receive income from it. Only a few received compensation or rent from the land during the war.

### Development of the "Fort Circle"

In 1898, an interest in connecting the forts by a road was proposed. Known as the Fort Drive, it would connect all the forts from the east of the city to the west.
In 1919 the Commissioners of the District of Columbia pushed Congress to pass a bill to consolidate the aging forts into a "Fort Circle" system of parks that would ring the growing city of Washington. As envisioned by the Commissioners, the Fort Circle would be a green ring of parks outside the city, owned by the government, and connected by a "Fort Drive" road in order to allow Washington's citizens to easily escape the confines of the capital. However, the bill allowing for the purchase of the former forts, which had been turned back over to private ownership after the war, failed to pass both the House of Representatives and Senate.
Despite that failure, in 1925 a similar bill passed both the House and Senate, which allowed for the creation of the National Capital Parks Commission (NCPC) to oversee the construction of a Fort Circle of parks similar to that proposed in 1919. The NCPC was authorized to begin purchasing land occupied by the old forts, much of which had been turned over to private ownership following the war. Records indicate that the site of Fort Stanton was purchased for a total of $56,000 in 1926. The duty of purchasing land and constructing the fort parks changed hands several times throughout the 1920s and 1930s, eventually culminating with the Department of the Interior and the National Park Service taking control of the project in the 1940s.
During the Great Depression, crews from the Civilian Conservation Corps embarked on projects to improve and maintain the parks, which were still under the control of District authority at that time. At Fort Stanton, CCC members trimmed trees and cleared brush, as well as maintaining and constructing park buildings. Various non-park buildings were also discussed for the land. The City Department of Education proposed building a school on park land, while authorities from the local water utility suggested the construction of a water tower would be suitable for the tall hills of the park. The Second World War interrupted these plans, and post-war budget cuts instituted by President Harry S. Truman postponed the construction of the Fort Drive once more. Though land for the parks had mostly been purchased, construction of the ring road connecting them was pushed back again and again. Other projects managed to find funding, however. In 1949, President Truman approved a supplemental appropriation request of $175,000 to construct "a swimming pool and associated facilities" at Fort Stanton Park.
In 1963, when President John F. Kennedy began pushing Congress to finally build the Fort Circle Drive, many in Washington and the National Park Service were openly questioning whether the plan had outgrown its usefulness. By this time, Washington, D.C. had grown past the ring of forts that had protected it a century earlier, and city surface roads already connected the parks, albeit not in as linear a route as envisioned. The plan to link the fort parks via a grand drive was quietly dropped in the years that followed and replaced by a plan to instead build a Fort Circle Trail.

### Administration

The National Capital Parks-East unit of the National Park Service administers Forts Foote, Greble, Stanton, Ricketts, Davis, Dupont, Chaplin, Mahan and Battery Carroll in the District of Columbia and Maryland. The Rock Creek Park unit administers Forts Bunker Hill, Totten, Slocum, Stevens, DeRussy, Reno, Bayard, Battery Kemble and Battleground National Cemetery in the District of Columbia. The George Washington Memorial Parkway administers Fort Marcy in Virginia.
In 2024 legislation was proposed that would reorganize the forts into a national historical park, though the National Park Service opposed changes to the existing administration.
