"The evils resulting from irregular requisitions, and foraging for the ordinary supplies of an army, are so very great, and so generally admitted, that it has become a recognized maxim of war, that the commanding officer who permits indiscriminate pillage, and allows the taking of private property without a strict accountability, whether he be engaged in defensive or offensive operations, fails in his duty to his own government, and violates the usages of modern warfare. It is sometimes alleged, in excuse for such conduct, that the general is unable to restrain his troops; but in the eye of the law there is no excuse; for _he who can not preserve order in his army has no right to command it_. In collecting military contributions, trustworthy troops should be sent with the foragers, to prevent them from engaging in irregular and unauthorized pillage; and the party should always be accompanied by officers of the staff and administrative corps, to see to the proper execution of the orders, and to report any irregularities on the part of the troops. In case any corps should engage in unauthorized pillage, due restitution should be made to the inhabitants, and the expenses of such restitution deducted from the pay and allowances of the corps by which such excess is committed. But modify and restrict it as you will, the system of subsisting armies on the private property of an enemy's subjects without compensation is very objectionable, and almost inevitably leads to cruel and disastrous results. There is, therefore, very seldom a sufficient reason for resorting to it." (Chap. 19, page 451.) "While there is some uncertainty as to the exact limit fixed by the voluntary law of nations to our right to appropriate to our own use the property of an enemy, or to subject it to military contributions, _there is no doubt whatever respecting its waste and useless destruction_. _This is forbidden alike by the law of nature and the rules of war._ There are numerous instances in military history where whole districts of country have been totally ravaged and laid waste. Such operations have sometimes been defended on the ground of necessity, or as a means of preventing greater evils. 'Such violent remedies,' says Vattel, 'are to be sparingly applied: there must be reasons of suitable importance to justify the use of them. He who does the like in an enemy's country when impelled by no necessity, or induced by feeble reasons, becomes the scourge of mankind.'
