Interval

In military dispositions and manœuvres, any given distance or space. In tactics the term is used to signify taken parallel to the front, as opposed to distance or space perpendicularly to the front. Interval between two battalions is the space which separates them when they are drawn up for action or when they are encamped. This space is generally wide enough to admit the march of another regiment; that is to say, it is equal to the extent of its front when in line. Interval between the line and the camp comprehends the space which lies between the camp and the line of intrenchments. It is generally from 180 to 200 toises in breadth; so that the different sections of troops which are nece ary for the security of the camp, may have room to move in, while sufficient ground is left in rear for troops to pa and repa as occasion may require. The same observation holds good with respect to contrevallation.
