Like the counterscarp
, this outer wall is intended as a security device.
70) The outlines of the new detached and attached counterscarps
and/or bastioned works are a mixture of the various ideas explored in De Gomme's draughts.
Having discussed counterscarp repairs at the Porta da traicao postern, the 1514 auto proceeds to detail scarps and counterscarps at the foot of two mutually adjacent towers--Torre do sino and Torre dos bizcainhos (Tower of the Biscayans).
By 1669, if Hollar is to be trusted, additions to the land-front consisted mainly of a complex counterscarp with tenaille heads, covered-way, and a lozenge-shaped redoubt toward the shore, closely emulating the works proposed in PRO [NAL] MPH 1 fol.
The Grand Socco occupies the open space extra muros, outside the old Fez Gate/Porta do campo, structured in the sixteenth and seventeenth centuries by the counterscarp of the town ditch and by the outer defences blocking approach to the gate.
Boytac unfortunately set the tone by grumbling from the very beginning about the ashlar and flagstones in the counterscarp, and by asserting that the stonework in the ditch was of poor quality and not well seated in mortar, although how he knew this begs a question, given that when the survey began, on 12 June 1514, the ditch was full of water.
40) He expressed few reservations about the stonework around the Porta de Ceuta drawbridge, its supports, the adjacent scarp and counterscarp, and the jambs of the gateway.

Places fortified, after the modern way, consist chiefly of Bastions, and Curtains, and Sometimes of Demi-bastions according to the Situation of the Ground, of Cavaliers, Ramparts, Fausse-brayes, Ditches, Counterscarps
, Cover'd Ways, Half Moons, Ravelins, Hornworks, Crownworks, Outworks, Esplanades, Redents, and Tenailles.
The only sections mentioned are located along the already partly rebuilt west wall and next to the Porta da traicao postern, and even so the measurements and specification deal only with relatively minor adjustments to scarps and counterscarps
at the foot of walls and towers.
During World War II, Operation Citadel (pinching off in 1943 the Soviet held salient centered around Kursk) failed because the Germans relied on the principles of the Blitzkrieg: speed was hampered by boobytraps, minefields, anti-tank diches, scarps and counterscarps
, hedgehogs, road blocks, barbed-wire entanglements and a myriad of other anti-tank and anti-personnel obstacles.
Others did fortify and rampire their walls, set up little fortresses, bastions, squared ravelins, digged trenches, cleansed countermines, fenced themselves with gabions, contrived platforms, emptied casemates, barricaded the false brays, erected the cavaliers, repaired the counterscarps
, plastered the curtains, lengthened ravelins, stopped parapets, morticed barbacans, assured the portcullises, fastened the hemes, sarasinesques, and cataracts, placed their sentries, and doubled their patrol.
