In fortification, tenaillons are works sometimes found constructed in a fortress, on each side of the ravelin. The short faces are traced on the prolongations of the faces of the ravelin, from the counterscarp of its ditch. The long faces are directed for the flanking defense, to about the middle of the faces of the bastions.
