US Presidency
1821

The laws making this provision were passed in 1815 and 1816, and it has been since the constant effort of the Executive to carry them into effect. The advantage of these fortifications and of an augmented naval force in the extent contemplated, in a point of economy, has been fully illustrated by a report of the Board of Engineers and Naval Commissioners lately communicated to Congress, by which it appears that in an invasion by 20,000 men, with a correspondent naval force, in a campaign of six months only, the whole expense of the construction of the works would be defrayed by the difference in the sum necessary to maintain the force which would be adequate to our defense with the aid of those works and that which would be incurred without them. The reason of this difference is obvious.
