Batage (Fr.). The time employed in reducing gunpowder to its proper consistency. The French usually consumed 24 hours in pounding the materials to make good gunpowder. Supposing the mortar to contain 16 pounds of composition, it would require the application of the pestle 3500 times each hour. The labor required in this process is less in summer than in winter, because the water is softer.
Bataillon de la Salade (Fr.). A name formerly given in France to old corps which wore a peculiar kind of helmet called salade. See [Salade].
Batardeau (Fr.). A wall built across a ditch or fortification, with a sluice-gate by which the height of the water in the ditch on both sides may be regulated. To prevent this wall being used as a passage across the ditch, it is built up to an angle at the top, and armed with iron spikes; and to render the attempt to cross still more difficult, a tower of masonry is built on it.

Bate Isle. An island of Hindostan, belonging to the province of Guzerat, situated at the southwestern extremity of the Gulf of Cutch. It was formerly a rendezvous for pirates, who were the dread of all traders on the western coast of India. In 1803 a naval force, consisting of a British frigate and two Bombay cruisers, succeeded in destroying several of the pirate boats and vessels; but an attack upon the castle, though conducted under the fire of the ships, was repulsed with some loss. In 1807 a treaty was entered into with the chiefs of the island, whereby they consented to relinquish their piratical practices.
