Not Included Below

• Appurtenant structures. Fort Winthrop, for example, in Boston Harbor is not listed as a fort.
• The towers at Charleston, Tybee Island, Key West (2), and New Orleans (2) and the battery at Bayou Bienvenue (Battery Bienvenue) are also not part of the list of 42.
• Northern Frontier forts, as Totten did not include them in the system in his reports. He listed them as a separate entity. He stated that the forts of the Third System were to be manned by militia artillery, while the Northern Frontier forts were to be manned by regular army. This seems like a minor difference, but it was really representative of a whole different philosophy of defense.
