Berm: Level earth between the parapet and the ditch, to keep the parapet from sliding into the ditch.
Cheveaux de Frize: Pieces of wood ten to twelve feet long with thin, wooden, pointed pins along the length of all four sides.
Ditch: Six to seven and a half foot crevasse immediately before the parapet.
Embrasures: Openings in the parapet for cannons to fire through.
Entrance: Positioned in the rear of the redoubt, and built wide enough for the artillery.
Fascines: Bundles of tree branches tied with yarn, from six to eighteen feet long and a foot or wider in girth. Used as a support structure in parapet construction. Assaulting troops used fascines to fill in the ditch and create a bridge to the parapet.
