The frequent success of the northern nations in storming towns, and more particularly the recovery of Brescia by the French, is proof sufficient of the truth of what I say. For the town of Brescia rising against the French while the citadel still held out, the Venetians, to meet any attack which might be made from the citadel upon the town, ranged guns along the whole line of road which led from the one to the other, planting them in front, and in flank, and wherever else they could be brought to bear. Of all which M. de Foix making no account, dismounted with his men-at-arms from horseback, and, advancing with them on foot through the midst of the batteries, took the town; nor do we learn that he sustained any considerable loss from the enemy’s fire. So that, as I have said, he who has to defend himself in a small town, when his walls are battered down and he has no room to retire behind other works, and has only his artillery to trust to, is at once undone.
But even where the town you defend is a great one, so that you have room to fall back behind new works, artillery is still, by a long way, more useful for the assailant than for the defender. For to enable your artillery to do any hurt to those without, you must raise yourself with it above the level of the ground, since, if you remain on the level, the enemy, by erecting any low mound or earthwork, can so secure himself that it will be impossible for you to touch him. But in raising yourself above the level of the ground, whether by extending yourself along the gallery of the walls, or otherwise, you are exposed to two disadvantages; for, first, you cannot there bring into position guns of the same size or range as he who is without can bring to bear against you, since it is impossible to work large guns in a confined space; and, secondly, although you should succeed in getting your guns into position, you cannot construct such strong and solid works for their protection as those can who are outside, and on level ground, and who have all the room and every other advantage which they could desire. It is consequently impossible for him who defends a town to maintain his guns in position at any considerable height, when those who are outside have much and powerful artillery; while, if he place it lower, it becomes, as has been explained, to a great extent useless. So that in the end the defence of the city has to be effected, as in ancient times, by hand to hand fighting, or else by means of the smaller kinds of firearms, from which if the defender derive some slight advantage, it is balanced by the injury he sustains from the great artillery of his enemy, whereby the walls of the city are battered down and almost buried in their ditches; so that when it comes once more to an encounter at close quarters, by reason of his walls being demolished and his ditches filled up, the defender is now at a far greater disadvantage than he was formerly. Wherefore I repeat that these arms are infinitely more useful for him who attacks a town than for him who defends it.
As to the remaining method, which consists in your taking up your position in an entrenched camp, where you need not fight unless you please, and unless you have the advantage, I say that this method commonly affords you no greater facility for avoiding an engagement than the ancients had; nay, that sometimes, owing to the use of artillery, you are worse off than they were. For if the enemy fall suddenly upon you, and have some slight advantage (as may readily be the case from his being on higher ground, or from your works on his arrival being still incomplete so that you are not wholly sheltered by them), forthwith, and without your being able to prevent him, he dislodges you, and you are forced to quit your defences and deliver battle: as happened to the Spaniards at the battle of Ravenna. For having posted themselves between the river Ronco and an earthwork, from their not having carried this work high enough, and from the French having a slight advantage of ground, they were forced by the fire of the latter to quit their entrenchments come to an engagement.
But assuming the ground you have chosen for your camp to be, as it always should, higher than that occupied by the enemy, and your works to be complete and sufficient, so that from your position and preparations the enemy dare not attack you, recourse will then be had to the very same methods as were resorted to in ancient times when an army was so posted that it could not be assailed; that is to say, your country will be wasted, cities friendly to you besieged or stormed, and your supplies intercepted; until you are forced, at last, of necessity to quit your camp and to fight a pitched battle, in which, as will presently appear, artillery will be of little service to you.
If we consider, therefore, for what ends the Romans made wars, and that attack and not defence was the object of almost all their campaigns, it will be clear,
