This subject has acquired much greater importance in modern warfare from two causes in particular. First, because the armies in general are now much greater than those of the middle ages, and even those of the old world; for, although formerly armies did appear here and there which equalled or even surpassed modern ones in size, still these were only rare and transient occurrences, whilst in modern military history, since the time of Louis XIV, armies have always been very strong in number. But the second cause is still more important, and belongs entirely to modern times. It is the very much closer inner connection which our wars have in themselves, the constant state of readiness for battle of the belligerents engaged in carrying them on. Almost all old wars consist of single unconnected enterprises, which are separated from each other by intervals during which the war in reality either completely rested, and only still existed in a political sense, or when the armies at least had removed so far from each other that each, without any care about the army opposite, only occupied itself with its own wants.
Modern wars, that is, the wars which have taken place since the Peace of Westphalia, have, through the efforts of respective governments, taken a more systematic connected form; the military object, in general, predominates everywhere, and demands also that arrangements for subsistence shall be on an adequate scale. Certainly there were long periods of inaction in the wars of the seventeenth and eighteenth centuries, almost amounting to a cessation of war; these are the regular periods passed in cantonments; still even those periods were subordinate to the military object; they were caused by the inclemency of the season, not by any necessity arising out of the subsistence of the troops, and as they regularly terminated with the return of summer, therefore we may say at all events uninterrupted action was the rule of war during the fine season of the year.
As the transition from one situation or method of action to another always takes place gradually so it was in the case before us. In the wars against Louis XIV. the allies used still to send their troops into winter cantonments in distant provinces in order to subsist them the more easily; in the Silesian war that was no longer done.
This systematic and connected form of carrying on war only became possible when states took regular troops into their service in place of the feudal armies. The obligation of the feudal law was then commuted into a fine or contribution: personal service either came to an end, enlistment being substituted, or it was only continued amongst the lowest classes, as the nobility regarded the furnishing a quota of men (as is still done in Russia and Hungary) as a kind of tribute, a tax in men. In every case, as we have elsewhere observed, armies became henceforward, an instrument of the cabinet, their principal basis being the treasury or the revenue of the government.
Just the same kind of thing which took place in the mode of raising and keeping up an establishment of troops could not but follow in the mode of subsisting them. The privileged classes having been released from the first of these services on payment of a contribution in money, the expense of the latter could not be again imposed on them quite so easily. The cabinet and the treasury had therefore to provide for the subsistence of the army, and could not allow it to be maintained in its own country at the expense of the people. Administrations were therefore obliged to look upon the subsistence of the army as an affair for which they were specially responsible. The subsistence thus became more difficult in two ways: first, because it was an affair belonging to government, and next, because the forces required to be permanently embodied to confront those kept up in other states.
Thus arose a separate military class in the population, with an independent organisation provided for its subsistence, and carried out to the utmost possible perfection.
