When Buonaparte had to retreat in 1812, it was impossible for him to do so by any other line but the one upon which he had advanced, on account of the subsistence of his army; and if he had attempted any other he would only have plunged into more speedy and certain destruction; all the censure therefore passed on him by even French writers as well as by others with regard to this point is sheer nonsense. 4.—Subsistence from Magazines. If we are to make a generic distinction between this method of subsisting troops and the preceding, it must be by an organisation such as existed for about thirty years at the close of the seventeenth and during the eighteenth century. Can this organisation ever reappear? Certainly we cannot conceive how it can be dispensed with if great armies are to be bound down for seven, ten, or twelve years long to one spot, as they have been formerly in the Netherlands, on the Rhine, in Upper Italy, Silesia, and Saxony; for what country can continue for such a length of time to endure the burden of two great armies, making it the entire source of their supplies, without being utterly ruined in the end, and therefore gradually becoming unable to meet the demands? But here naturally arises the question: shall the war prescribe the system of subsistence, or shall the latter dictate the nature of the war? To this we answer: the system of subsistence will control the war, in the first place, as far as the other conditions on which it depends permit; but when the latter are encroached upon, the war will react on the subsistence system, and in such case determine the same. A war carried on by means of the system of requisitions and local supplies furnished on the spot has such an advantage over one carried on in dependence on issues from magazines, that the latter does not look at all like the same instrument. No state will therefore venture to encounter the former with the latter; and if any war minister should be so narrow-minded and blind to circumstances as to ignore the real relation which the two systems bear to each other, by sending an army into the field to live upon the old system, the force of circumstances would carry the commander of that army along with it in its course, and the requisition system would burst forth of itself. If we consider besides, that the great expense attending such an organisation must necessarily reduce the extent of the armament in other respects, including of course the actual number of combatant soldiers, as no state has a superabundance of wealth, then there seems no probability of any such organisation being again resorted to unless it should be adopted by the belligerents by mutual agreement, an idea which is a mere play of the imagination.
