in military affairs, a musqueteer, mounted on horseback, who sometimes fights or marches on foot, as occasion requires.
Dragoons are divided into brigades, as the cavalry, and each regiment into troops; each troop having a captain, lieutenant, cornet, quarter-master, two ferjeants, three corporals, and two drums. Some regiments have hautboys: they are very useful on any expedition that requires dispatch, for they can keep pace with the cavalry, and do the duty of infantry: they encamp generally on the wings of the army, or at the passes leading to the camp; and sometimes they are brought to cover the general's quarters: they do duty on the generals of horse and dragoons, and march in the front and rear of the army.
