BASKETS, in military affairs, are simple baskets, frequently used in sieges. They are filled with earth, and placed on the parapet of the trench, or any other part. They are generally about a foot and a half in diameter at the top, and eight inches at the bottom, and a foot and a half in height; so that, being placed on the parapet, a kind of embrasure is formed at the bottom, through which the soldiers fire, without being exposed to the shot of the enemy. See [Gabion].
