Remarks on the aforegoing Estimate
This estimate is some what different in the size of the calibres from those that have been presented for the same purpose in the two preceeding years. But the time for preparation at those periods was so exceeding short as to preclude a possibility of obtaining heavier cannon, and therefore there was an imposed obligation of using those in our possession although the effect would have been less than from those of a larger nature.
There are great variety of articles necessary for the service of the ordnance, which must be made in the laboratories and can be procured in the States which are not enumerated in the estimate.
It must be observed that every thing provided in consequence of any former estimate can be applied as part of the present without a superfluous article.
Probably the 32 pounders may be borrowed of Massachusetts, that State being in possession of the Somersetts cannon of this calibre. But it is much to be doubted whether they have the proper number of shot.
Six 24 pounders are contained in the returns as belonging to the Continent—at New port, Philadelphia, and one at West Point; but there is some dispute whether they belong to the Continent or to the States.
The 18 pounders might be taken from West Point. There are also some returned as belonging to the Continent, in Rhode Island and in Pennsylvania.
The 12 pounders are in possession at different Places and at West Point.
Two 13 inch mortars, left at Boston by the enemy, are by a resolve of Congress subject to the orders of Congress or those of the Commander in Chief.
The 10—8—& 5 1/2 inch mortars are in possession.
The 5 1/2 inch—and five of the 8 inch howitzers are in possesion. The seven remaining 8 inch are wanting.
For the actual service of the artillery which are to be exposed to the fire of the Enemy, the pieces must have garrison carriages with iron trucks. For various services it is necessary to have travelling carriages a sufficiency of which for the 18 & 12 pounders are at West Point.
The estimate supposes New York to be the point of operation, as a great proportion of the cannon and mortars are to be drawn from West Point, which cannot be the case in so great a degree if any other object is in contemplation. However, if all the ordnance and stores are provided as in this estimate a very respectable apparatus can be appropriated to any other expedition.
