FABRIZIO: I have shown you how to organize an army to battle another army which is seen posted against you, and I have told you how it is overcome, and also of the many circumstances which can occur because of the various incidents surrounding it, so that it appears to me now to be the time to show you how to organize an army against an enemy which is unseen, but which you are continually afraid will assault you. This happens when marching through country which is hostile, or suspected (of being so). And first you have to understand that a Roman Army ordinarily always sent ahead some groups of cavalry as observers for the march. Afterwards the right wing followed. After this came all the wagons which pertained to it. After those, another Legion, and next its wagons. After these come the left wing with its wagon in the rear, and the remainder of the cavalry followed in the last part. This was in effect the manner in which one ordinarily marched. And if it happened that the Army should be assaulted on the march in front or from the rear, they quickly caused all the wagons to be withdrawn either on the right, or on the left, according as it happened, or rather as best they could depending on the location, and all the forces together, free from their baggage, set up a front on that side from which the enemy was coming. If they were assaulted on the flank, they would withdraw the wagons to the side which was secure, and set up a front on the other. This method being good, and prudently conducted, appears to me ought to be imitated, sending cavalry ahead to observe the country, then having four battalions, having them march in line, and each with its wagons in the rear. And as the wagons are of two kinds, that is, those pertaining to individual soldiers, and the public ones for use by the whole camp, I would divide the public wagons into four parts, and assign a part to each Battalion, also dividing the artillery and all the unarmed men, so that each one of those armed should have its equal share of impedimenta. But as it sometimes happens that one marches in a country not only suspect, but hostile in fact, that you are afraid of being attacked hourly, in order to go on more securely, you are compelled to change the formation of the march, and go on in the regular way, so that in some unforeseen place, neither the inhabitants nor the Army can injure you. In such a case, the ancient Captains usually went on with the Army in squares, for such they called these formations, not because it was entirely square, but because it was capable of fighting on four sides, and they said that they were going prepared either for marching or for battle. I do not want to stray far from this method, and want to arrange my two Battalions, which I have taken as a rule for an Army, in this manner. If you want, therefore, to walk securely through the enemy country, and be able to respond from every side, if you had been assaulted by surprise, and wanting, in
