The Rodman gun is any of a series of American Civil War–era columbiads designed by Union artilleryman Thomas Jackson Rodman (1815–1871). The guns were designed to fire both shot and shell. These heavy guns were intended to be mounted in seacoast fortifications. They were built in 8-inch, 10-inch, 13-inch, 15-inch, and 20-inch bore. Other than size, the guns were all nearly identical in design, with a curving bottle shape, large flat cascabels with ratchets or sockets for the elevating mechanism. Rodman guns were true guns that did not have a howitzer-like powder chamber, as did many earlier columbiads. Rodman guns differed from all previous artillery because they were hollow cast, a new technology that Rodman developed that resulted in cast-iron guns that were much stronger than their predecessors.
Dahlgren guns were muzzle-loading naval artillery designed by Rear Admiral John A. Dahlgren USN, mostly used in the period of the American Civil War. Dahlgren's design philosophy evolved from an accidental explosion in 1849 of a 32 lb (14.5 kg) gun being tested for accuracy, killing a gunner. He believed a safer, more powerful naval cannon could be designed using more scientific design criteria. Dahlgren guns were designed with a smooth curved shape, equalizing strain and concentrating more weight of metal in the gun breech where the greatest pressure of expanding propellant gases needed to be met to keep the gun from bursting. Because of their rounded contours, Dahlgren guns were nicknamed "soda bottles", a shape which became their most identifiable characteristic.

Fort Stanton was a Civil War-era fortification constructed in the hills above Anacostia in the District of Columbia, USA, and was intended to prevent Confederate artillery from threatening the Washington Navy Yard. It also guarded the approach to the bridge that connected Anacostia with Washington.

Following the surrender of the Army of Northern Virginia, it was dismantled and the land returned to its original owner. It never saw combat. Abandoned after the war, the site of the fort was planned to be part of a grand "Fort Circle" park system encircling the city of Washington. Though this system of interconnected parks never was fully implemented, the site of the fort is today a park maintained by the National Park Service, and a historical marker stands near the fort's original location.
Fort Bayard was an earthwork fort constructed in 1861 northwest of Tenleytown in the District of Columbia as part of the defenses of Washington, D.C., during the American Civil War.
