CORDON
, in Fortisication, a row of stones jutting out between the rampart and the basis of the parapet, like the tore of a column. The cordon ranges round the whole fortress, and serves to join the rampart, which is aslope, and the parapet, which is perpendicular, more agreeably together.
In fortifications raised of earth, this space is filled up with pointed stakes, instead of a cordon.
