Rasante

In the design of permanent fortification the term rasante referred to the method of developing the profiles of successive works of a fortification in such a way that outworks protected retired works and the enceinte of a fortified place from being seen or readily distinguished at any appreciable distance from the fortification. When retired works could not be seen clearly, if at all, they could not be accurately bombarded by distant artillery fire. The idea of rasante fortifications was developed by Cormontaingne, a French engineer of the early eighteenth century, whose improvements on Vauban's methods called for protecting all but a few feet of the upper part of masonry scarp walls from the enemy's view and reducing the command of retired works over advanced works to a minimum consistent with an effective and vigorous defense.
