IV. In the next place, it is unnecessary to destroy an enemy's country, when he has other sources, from which he can draw his supplies, as for instance, the sea or any adjoining territory. Archidamus, in Thucydides, attempting to dissuade the Lacedaemonians from a war with the Athenians, asks them, what object they propose to themselves by such a war? he asks them if they suppose that Attica can easily be laid waste owing to the advantage, which their troops have in superiority and numbers? but, says he, they have other dominions to furnish them with supplies, and they can avail themselves also of maritime importations. So that under such circumstances, it is best to leave agriculture unmolested, even on the frontiers of each side: a practice lately followed in the wars of the low countries, where contributions were paid to both parties, in return for such protection.
V. There are some things of such a nature, as to contribute, no way, to the support and prolongation of war: things which reason itself requires to be spared even during the heat and continuance of war. Polybius calls it brutal rage and madness to destroy things, the destruction of which does not in the least tend to impair an enemy's strength, nor to increase that of the destroyer: Such are Porticos, Temples, statues, and all other elegant works and monuments of art. Cicero commends Marcellus for sparing the public and private edifices of Syracuse, as if he had come with his army to protect THEM, rather than to take the place by storm.
VI. As this rule of moderation is observed towards other ornamental works of art, for the reasons before stated, there is still greater reason, why it should be obeyed in respect to things devoted to the purposes of religion. For although such things, or edifices, being the property of the state may, according to the law of nations, be with impunity demolished, yet as they contribute nothing to aggravate the calamities, or retard the successes of war, it is a mark of reverence to divine things to spare them, and all that is connected therewith: and more especially should this rule be adhered to among nations, worshipping the same God according to the same fundamental laws, although differing from each other by slight shades of variation in their rights and opinions. Thucydides says that it was a law among the Greeks of his time, in all their invasions of each other's territories, to forbear touching the edifices of religion: and Livy likewise observes that, upon the destruction of Alba by the Romans, the temples of the Gods were spared.
VII. What has been said of the sacred edifices of religion applies also to monuments raised in honour of the dead, unnecessarily to disturb whose ashes in their repose bespeaks a total disregard to the laws and ties of our common humanity.
VIII. Although it does not fall within the province of this treatise to inquire into the utility of war in all its various branches, but only to regulate its practices by confining them within due and lawful bounds; yet it will not be improper to observe that rules and practices derive much of their merit from the utility, with which they are attended. So that one great quality, to recommend the moderation above alluded to, will be found in its preventing the enemy from being driven to those resources, which men never fail, at last, of finding in despair. It is a just remark made by some Theologians, that all Christian princes and rulers, who wish to be found SUCH in the sight of God as well as that of men, will deem it a duty to interpose their authority to prevent or to suppress all UNNECESSARY violence in the taking of towns: for acts of rigour can never be carried to an extreme without involving great numbers of the innocent in ruin. And practices of that kind, besides being no way conducive to the termination of war, are totally repugnant to every principle of Christianity and justice.
[CHAPTER XIII.]
On Moderation in Making Captures in War.
Effects belonging to the subjects of an enemy, and taken detained as a pledge or debt—Not to be taken by way of punishment for another's offence—The debt or obligation, arising from a state of war, illustrated by examples—Forbearance in the exercise of such a right from principles of humanity.
I. The capture of an enemy's goods, even in JUST WAR, is not, in ALL CASES, perfectly justifiable, nor is the captor always exempt from the ties of restitution. For strictly speaking, according to the rules of pure justice, it is not lawful to seize or detain goods except to the exact amount of the debt which the enemy has incurred. Indeed goods may be detained beyond that, as a necessary pledge of security, but still upon the condition of being restored, as soon as the danger has ceased: RESTORED EITHER LITERALLY, OR BY SOME PROPER COMPENSATION BEING MADE.
