Covered Way

Sometimes referred to as the Covert Way. Adapted From Barnard, Defenses of Washington, Page 74In field fortifications covered ways were routes of passage or roads sheltered from enemy fire by sinking the road surface in a trench and protecting the engaged side of the trench with a parapet. The profile of covered ways was generally very similar to the first parallel in siege works or simple unrevetted rifle trenches with the trench excavated wide enough for free circulation of troops and the passage of wagons or artillery. Covered ways were generally employed to connect two or more works through ground exposed to enemy fire.

In permanent fortifications covered ways were outworks that ran parallel to the crest of the counterscarp which allowed the garrison to guard and defend the glacis and provided an open area exterior to the enceinte where troops could be massed for a sortie or rallied after a sortie. The covered way was immediately in rear of the glacis and generally 7 to 8 feet below the crest of the glacis. In Vauban's First Method the covered way was about 10 yards wide; its width being limited in an attempt to make it difficult for attacking an enemy to establish an effective lodgment along the crest of the counterscarp.

Both salient and re-entering places of arms were elements of the covered way.
