It seems everywhere to be well Mounted with Cannon Except on the land side, where none are wanting, because they could be of no use, the land being so very high above it.
Yet, after all, neither this Fort nor those on the opposite shore do not appear to be of any great Strength, even against Shipping, for which they are wholly design'd, being the key of the Bay.

They lay low, and Ships may come so near as to have them entirely within the reach of their Guns; but it would require 5 or 6 Sail of the line to insure Success.

Between 2 and 3 Miles within the Entrance of the Bay, on the West Side, is the Isle Borghleone, upon the east point of which is Erected a Battry of Stone, and Mounted with 17 pieces of Cannon.

Besides this, on the highest part of the Island, is a Battry of 6 Guns mounted on an Open Platform.

These battrys are designed to play upon Shipping in the Bay, and seems not ill designed for that purpose; yet they would be Obliged to Submit to the Attack of Shipping or that of a Land force, there being nothing to hinder the latter from Landing on the Island behind the Battrys.
