Forts and fortresses.--There is but one fortress in the United States
; all the other fortified places defending our harbors are called forts.
Tlhe distinction betwixt these two terms is very wide.
All fortresses are forts or fortified places; but all forts are not fortresses.
A fort may be simply an advanced work to protect the extended lines or walls of a fortress.
Generally fortresses are extensive enceintes
for the reception of garrisons, and built for the protection of cities.
In the United States
no extensive fortified places, with large garrisons, have been constructed for the defence of cities.
Fortifications in this country have had reference principally to harbor defence.
, with its capacity for a garrison, (it includes 75 acres,) was constructed for the defence of the important Navy Yard of Gosport
, now in possession of Virginia
or the Confederate States
The construction of the extensive walls of a fortress involves the highest science of engineering.
Not so with the forts.
The former implies polygons, bastions, curtains, glacis, covered ways, planks, scarps and counter-scarps, ravelins, redans, redoubts, and the whole vocabulary of engineering science.
Add to this idea a vast enceinte
, or circumvallation, to contain a large garrison of troops, and a fortress rises to its proportionate majesty.
A full garrison for Fortress Monroe
is 3,000 men.--National Intelligencer, June 6
