Sea-Mortar-Beds, are made of solid timber, having a hole in the centre to receive the pintle or strong iron bolt, about which the bed turns. Sea-mortars are mounted on these beds, on board of the bomb-ketches.

These beds are placed upon very strong timber frames, fixed into the bomb-ketch, in which the pintle is fixed, so as the bed may turn about it, to fire any way. The fore part of these beds is an arc of a circle described from the same centre as the pintle-hole.

Stool-Bed, is a piece of wood on which the breech of a gun rests upon a truck-carriage, with another piece fixed to it at the hind end, that rests upon the body of the hind axle-tree; and the fore part is supported by an iron bolt. See [Carriage].

BEEF-Eaters, the yeomen of the guard to the king of Great Britain are so called, being kept up rather for pageantry, than for any military service. Their arms are a sabre and lance; and the dress of the 13th century.

BEETLES, in a military sense, are large wooden hammers for driving down pallisades, and for other uses, &c.
