Others have regulated this question as to their armies thus if your enemy come full drive upon you, stand firm to receive him; if he stand to receive you, run full drive upon him.
In the expedition of the Emperor Charles V. into Provence, King Francis was put to choose either to go meet him in Italy or to await him in his own dominions; wherein, though he very well considered of how great advantage it was to preserve his own territory entire and clear from the troubles of war, to the end that, being unexhausted of its stores, it might continually supply men and money at need; that the necessity of war requires at every turn to spoil and lay waste the country before us, which cannot very well be done upon one's own; to which may be added, that the country people do not so easily digest such a havoc by those of their own party as from an enemy, so that seditions and commotions might by such means be kindled amongst us; that the licence of pillage and plunder (which are not to be tolerated at home) is a great ease and refreshment against the fatigues and sufferings of war; and that he who has no other prospect of gain than his bare pay will hardly be kept from running home, being but two steps from his wife and his own house; that he who lays the cloth is ever at the charge of the feast; that there is more alacrity in assaulting than defending; and that the shock of a battle's loss in our own bowels is so violent as to endanger the disjointing of the whole body, there being no passion so contagious as that of fear, that is so easily believed, or that so suddenly diffuses itself; and that the cities that should hear the rattle of this tempest at their gates, that should take in their captains and soldiers yet trembling and out of breath, would be in danger in this heat and hurry to precipitate themselves upon some untoward resolution: notwithstanding all this, so it was that he chose to recall the forces he had beyond the mountains and to suffer the enemy to come to him. For he might, on the other hand, imagine that, being at home and amongst his friends, he could not fail of plenty of all manner of conveniences; the rivers and passes he had at his devotion would bring him in both provisions and money in all security, and without the trouble of convoy; that he should find his subjects by so much the more affectionate to him, by how much their danger was more near and pressing; that having so many cities and barriers to secure him, it would be in his power to give the law of battle at his own opportunity and advantage; and that, if it pleased him to delay the time, under cover and at his ease he might see his enemy founder and defeat himself with the difficulties he was certain to encounter, being engaged in a hostile country, where before, behind, and on every side war would be made upon him; no means to refresh himself or to enlarge his quarters, should diseases infest them, or to lodge his wounded men in safety; no money, no victuals, but at the point of the lance; no leisure to repose and take breath; no knowledge of the ways or country to secure him from ambushes and surprises; and in case of losing a battle, no possible means of saving the remains. Neither is there want of example in both these cases.
Scipio thought it much better to go and attack his enemy's territories in Africa than to stay at home to defend his own and to fight him in Italy, and it succeeded well with him. But, on the contrary, Hannibal in the same war ruined himself by abandoning the conquest of a foreign country to go and defend his own. The Athenians having left the enemy in their own dominions to go over into Sicily, were not favoured by fortune in their design; but Agathocles, king of Syracuse, found her favourable to him when he went over into Africa and left the war at home.
By which examples we are wont to conclude, and with some reason, that events, especially in war, for the most part depend upon fortune, who will not be governed by nor submit unto human reasons and prudence, according to the poet:
"Et male consultis pretium est: prudentia fallit Nec fortune probat causas, sequiturque merentes, Sed vaga per cunctos nullo discrimine fertur.
Scilicet est aliud, quod nos cogatque regatque Majus, et in proprias ducat mortalia leges."
["And there is value in ill counsel: prudence deceives: nor does fortune inquire into causes, nor aid the most deserving, but turns hither and thither without discrimination. Indeed there is a greater power which directs and rules us, and brings mortal affairs under its own laws."--Manilius, iv. 95.]
But, to take the thing right, it should seem that our counsels and deliberations depend as much upon fortune as anything else we do, and that she engages also our arguments in her uncertainty and confusion.
"We argue rashly and adventurously," says Timaeus in Plato, "by reason that, as well as ourselves, our discourses have great participation in the temerity of chance."
