the attacking a place, work, or the like, with heavy artillery.

To batter in breach, is to play furiously on a work, as the angle of a half-moon, in order to demolish and make a gape therein. In this they observe never to fire a piece at the top, but all at the bottom, from three to six feet from the ground.

The battery of a camp is usually surrounded with a trench, and palliades at the bottom, with two redoubts on the wings, or certain places of arms, capable of covering the troops which are appointed for their defence. See Battery.
