Fort Dupont was commenced between Ocotober and December of 1861 and "completed" in the spring on 1862. like most of the older works it underwent some modifications between 1861 and 1865.

It was never a strong work and in 1862, a commission studying the Defenses of Washington, noted that a deep ravine to the west of the fort should be covered by a blockhouse.
