Samuel Cooper

The Civil War Defenses were generally named after well known Union officers (many deceased during the war). This was not always the case. Fort Williams was first named Fort Traitor because the owner, Samuel Cooper(left), pledged an oath to the Union only to become a Confederate later on in the war.
