Nam cum ante equites in suam quisque gentem discriberentur seorsus a ceteris, exempto nationum discrimine, praefectis non utique suarum gentium, sed delectis attribuit Tuba, cum castra movere vellet, signum dabat, cuius sonus plerumque tumultuantium fremitu exoriente haud satis exaudiebatur; ergo perticam, quae undique conspici posset, supra praetorium statuit, ex qua signum eminens pariter omnibus conspicuum observabatur, ignis noctu, fumus interdiu.
For whereas before the cavalry were enrolled each man in his own race, apart from the rest, he gave up the separation by nations and assigned them to commanders not necessarily of their own people, but of his own choice When he wished to move his camp, he used to give the signal with the trumpet, the sound of which was often not readily enough heard amid the noise made by the bustling soldiers; therefore he set up a pole on top of the generals tent, which could be clearly seen from all sides, and from this a lofty signal, visible to all alike, was watched for, fire by night, smoke in the daytime.
