Bordeaux, or Bourdeaux (Southwest France). This city was sacked by the Visigoths, who were driven from it by Clovis; it was ravaged by the Saracens and Normans in the 8th and 9th centuries. It came into the possession of the Duke of Gascoyne in 911; in 1653 the city rebelled, but was taken by the royal troops; Bordeaux was entered by the victorious British army after the battle of Orthes, fought February 27, 1814.
Bordure, or Border. In heraldry, coats of arms are frequently surrounded with a bordure, the object of which is to show that the bearer is a cadet of the house whose arms he carries. Its character often has reference to the profession of the bearer; thus a bordure embattled is granted to a soldier, and a bordure ermine to a lawyer.
Bore. Of a piece of ordnance includes all the part bored out, viz., the cylinder, the chamber (if there is one), and the conical or spherical surface connecting them.
Borghetto. A town of Italy, on the Mincio, 15 miles southwest of Verona; it has a castle and a vast fortified causeway. The French here defeated the Austrians in 1796.
Borgo Forte. A town of Italy, in Lombardy, on the Po, 7 miles south of Mantua. The Austrians were here defeated by the French in 1796.
Bori. A Turkish term for military trumpets.
Boring Cannon. See [Ordnance, Construction of].
Borissov. A town of Russia, on the left bank of the Berezina. A conflict took place here November 23, 1812, between the French and Russians; near this town, at the village of Studienka, the disastrous passage of Berezina was effected by the French army, November 26-27, 1812.
Bormann-fuze. A fuze which is used for spherical case-shot. The fuze-case is made of metal (a composition of lead and tin), and consists of a short cylinder, having at one end a horseshoe-shaped indentation, one end only of which communicates with the magazine of the fuze placed in the centre by a channel filled with rifle powder. This horseshoe indentation extends nearly to the other end of the cylinder, a thin layer of the metal only intervening. This is graduated on the outside into equal parts representing seconds and quarter-seconds. In the bottom of this channel a smooth layer of the composition is placed, with a piece of wick or yarn underneath it. On this is placed a piece of metal, the cross-section of which is wedge-shaped, and this, by machinery, is pressed down upon the composition, sealing it hermetically. The cylindrical opening is filled with musket powder and covered with a sheet of tin, which is soldered, closing the magazine from the external air. Before using the fuze several holes are punched through this sheet of tin, to allow the flame to enter the shell. On the side of the fuze the thread of a screw is cut which fits into one cut on the inside of the fuze-hole, and the fuze is screwed into the shell with a wrench. The thin layer of metal over the composition is cut through with a gouge or chisel, or even a penknife, at the interval marked with the number of seconds which we wish the fuze to burn. To prevent the metal of this fuze, which is soft, from being driven into the shell by the explosive force of the charge, a circular piece of iron, with a hole through its centre, and the thread of a screw on the outside, is screwed into the fuze-hole before the fuze is inserted. The most important advantage of this fuze is, that the shells can be loaded, all ready for use, and remain so any length of time, perfectly safe from explosion, as the fuze can be screwed into its place, and the composition never exposed to external fire until the metal is cut through.
Borneo. An island in the Indian Ocean, the largest in the world except Australia; discovered by the Portuguese about 1520; the pirates of this island were several times chastised by the British government; incorporated with the British empire, December 2, 1846.
