He had improved the tactics, without violating the manners, of his nation, [41] whose force still consisted in the missile weapons, and rapid evolutions, of a numerous cavalry. From a single troop to a great army, the mode of attack was the same: a foremost line first advanced to the charge, and was supported in a just order by the squadrons of the great vanguard.
