BATTLE-_Array_, _Line of_ BATTLE, the method and order of arranging the troops in order or line of battle; the form of drawing up the army for an engagement. This method generally consists of three lines, viz. the front line, the rear line, and the reserve. The second line should be about 300 paces behind the first, and the reserve at about 5 or 600 paces behind the second. The artillery is likewise divided along the front of the first line. The front line should be stronger than the rear line, that its shock may be more violent, and that, by having a greater front, it may more easily close on the enemy’s flanks. If the first line has the advantage, it should continue to act, and attack the enemy’s second line, terrified by the defeat of their first. The artillery must always accompany the line of battle in the order it was at first distributed, if the ground permit it; and the rest of the army should follow the motions of the first line, when it continues to march on after its first success. BATTLE-_Ax_, an offensive weapon, formerly much used by the Danes, and other northern infantry. It was a kind of halbert, and did great execution when wielded by a strong arm. _Main_-BATTLE. See BATTLE-_Array_. BATTLEMENTS, in military affairs, are the indentures in the tops of old castles or fortified walls, or other buildings, in the form of embrasures, for the greater conveniency of firing or looking through.
