Detached REDOUBT, is a work made at some distance from the covert-way, much in the same manner as a ravelin with flanks. See [Arrow].
Redoubts en cremaillere, differ from all the rest, because the inside line of the parapet is broken in such a manner as to resemble steps of stairs, or teeth of a saw; whereby this advantage is gained, that a greater fire can be brought to bear upon the defile, than if only a simple face was opposed to it, and consequently the passage is rendered more difficult.
