Examples
“The glacis is the smooth ground outside the ditch.”
“Thus the ground beyond the ditch, that is, the glacis, covers the walls from the shot of a besieger, and renders it extremely difficult to reach them.”
“The purpose of the glacis, which is an inclined plane, is to expose an attacking party to the fire of the guns, which are so placed as to sweep it from the crest of the counterscarp to the edge of the beach.”
“At the base is a kind of glacis, which runs up at an angle of forty-five from the plain to within fifty, and, in some places, within twenty feet of the foot of the wall.”
“This crusts over the whole glacis of the eastern and northern parts of the piedmont giving very poor soils, usually skeletal lithosols if present at all.”
“It rises abruptly 1,000 m above an almost flat surrounding glacis.”
“Again there was no moat, just a glacis, so that they had to mount a kind of stone hill leading up to the wall.”
“The Germans labored up the glacis slowly at the most exposed places; now crawling on their bellies, now creeping on hands and knees, but, in the main, moving with erect and steady bearing.”
Fictionaut: She Makes Her Mouth Small & Round & Other Stories
“The landscape is characterized by volcanic piles with precipitous slopes, and deeply incised valleys (glacis slopes).”
“The inner walls of the Crac are ringed by a smooth slope called a glacis.”

knitandpurl "The Dwelling seemed to be a sort of town of rounded buildings more like lime-kilns than anything else, with arched doors leading to dark insides. They were all built of tiny stones, such as lay on the beach. Beyond the huts or houses towered the castle, a vast rough structure with towers and arches and buttresses and bastions and glacis and bridges and a great moat all around it."
