A gate or passage, by which the garrison of a fortress may make a sally or sudden attack on the besiegers. The name is applied to the postern leading from under the rampart into the ditch, but its more modern application is to a cutting through the glacis, by which a sally may be made from the covert way. When not in use, sally ports are closed by massive gates of timber and iron.
