Lunette

In field fortification a lunette was a detached field work open at the gorge traced with two faces forming a salient angle and two flanks adjoining the faces. Lunettes were employed in much the same fashion as redans: as advanced works or elements within a line with intervals. In the design of Fortress Rosecrans, at Murfreesboro, Tennessee, large irregular lunettes were used to fortify the perimeter of the entrenched camp.

In permanent fortifications a lunette was a type of outwork constructed to shield demi-lune faces, create crossing columns of fire across the salient of the demi-lune, and partially cover bastion faces from distant artillery fire. Lunettes were similar to tenaillons (which sometimes called great lunettes), but did not extend beyond the faces of the demi-lune or throw the demi-lune salient into a deep re-entering angle.
