Explanation:

Under the Articles, the states, not Congress, had the power to tax. ... Power was concentrated in a single assembly, rather than being divided, as in the state governments, into separate houses and branches. Further, members of the Confederation Congress were selected by state governments, not by the people.

That´s why the forts were built on high land overlooking the Potomac and Anacostia rivers, as well as roads leading to Washington, which were important strategic locations for the Union soldiers. As an example, Fort Totten was built atop a ridge along the main road from Washington to Maryland, near the Capitol.
