Whenever a regiment remains more than one night in a camp, regular kitchens are to be constructed. No tents, or huts, are to be allowed in front of, or between the intervals of the battalions. A spot or ground for this purpose should be marked by the quarter-master, with the approbation of the commanding officer. On arriving in a camp which is intersected by hedges, ditches, unequal or boggy ground, regiments will immediately make openings of communication, of 60 feet in width. The ground in front of the encampment is to be cleared, and every obstacle to the movement of the artillery and troops is to be removed. Commanding officers of regiments must take care that their communication with the nearest grand route is open, and free from any impediments. ENCEINTE, in _fortification_, is the interior wall or rampart which surrounds a place, sometimes composed of bastions or curtains, either faced or lined with brick or stone, or only made of earth.

ENCLOUEURE, _Fr._ this term is used in the artillery, to signify the actual state and condition of any thing that has been spiked.

ENFILADE, in _fortification_, is used in speaking of trenches, or other places, which may be scoured by the enemy’s shot, along their whole length. In conducting the approaches at a siege, care must be taken that the trenches be not _enfiladed_ from any work of the place.
