In
the process of defilading a field work from fire delivered from a commanding
height within 1,000 yards the rampant plane was a plane that passed from
a line 3 feet above the established line of a field work's gorge, through
the line of the interior of the interior crest, to the highest point of ground
where the an enemy could see the interior of the work. Some period manuals
refer to the rampant plane as the plane of the site. |
