Now it is clearly demonstrable from the coincidence of dates, from the exact time required for a special effort of this kind, and from the rate at which munitions and equipment were accumulated, that the Government at Berlin came to a decision in the month of July 1911 to force war upon Russia and upon France immediately after the harvest of 1914; and of a score of indications which all converge upon these dates, not one fails to strike them exactly by more than a few weeks in the matter of preparation, by more than a few days in the date at which war was declared. Under those circumstances, Berlin with her ally at Vienna had the immense numerical advantage over the French and the Russians when war was suddenly forced upon those countries on the 31st of July last year. But, as in the case of men, the advantage would only be overwhelming during the first period. The very fact that the war had to be won quickly involved an immense expenditure of heavy ammunition in the earlier part of it, and this expenditure, if it were not successful, would be a waste. It takes about five months to produce a heavy piece, and the rate of production of heavy ammunition, though slow, is measurable. At the moment of writing this, towards the close of the second period, the balance is not yet redressed, but it is in a fair way to be redressed. The imperfect and too tardy blockade to which the enemy is somewhat timidly subjected is a factor in aid of this; and we may be fairly confident that, if a third period is reached before the enemy shall have the advantage of a decision, there will be a preponderance of munitioning upon the Allied side in the West and the East which will be, if anything, of superior importance to the approaching preponderance in numbers. Having thus briefly surveyed the opposing strength of either combatant, checked and measured as it varied with the progress of the war, we will turn to the _moral_ opposition of military theory between the one party and the other, and show how here again that, _save in the most important matter of all, grand strategy_, the enemy was on the highroad to the victory which he confidently and, for that matter, reasonably expected. (3) THE CONFLICTING THEORIES OF WAR. The long peace which the most civilized parts of Europe had enjoyed for now a generation left more and more uncertain the value of theories upon the conduct of war, which theories had for the most part developed as mere hypotheses untested by experience during that considerable period. The South African and the Manchurian war had indeed proved certain theories sound and others unsound, so far as their experience went; but they were fought under conditions very different from those of an European campaign, and the progress of material science was so rapid in the years just preceding the great European conflict that the mass of debated theories still remained untried at its outbreak.
