There are three periods in war. There is the onset of war, where swiftness of action is what tells most; there is the grip of war, where numbers of trained men are what tell most; and there is the drag of war, when what tells most is the purse.
Speaking by the book, it is of course numbers which tell all the way through. At the beginning—in the onset—the aim is to hurl superior numbers at a vital point—taking the enemy by surprise, and thereby disordering his whole plan of campaign—very much as you knock a limpet off a rock, with a sharp unexpected blow.
If this effort fails to settle matters, then we are in the grip. Here it is a case of sheer heavy slogging of all the available trained troops. The weaker side is driven to the defensive. It is found making use of every artificial and natural advantage to counteract the superiority which threatens it, and which must speedily prevail, if only it be superior enough.
Finally, after a longer or shorter period of indecisive deadlock, the time comes when trained troops and material of war accumulated in advance begin to run short—when new levies, raised since the war broke out, begin to take the field, well or ill equipped, well or ill armed, as the case may be. When this stage is reached we are in the drag of war; and the side which can best afford to feed, clothe, and arm its fresh reinforcements stands at an enormous advantage.
In 1870 war was announced on July 15th, and formally declared on the 19th. Three weeks later, on August 6th, the important battles of Woerth and Spicheren were won by the Germans. On September 2nd, the issue of the war was decided, when the Emperor of the French, with his main army, surrendered at Sedan. Metz fell in the last days of October, and Paris on the first day of March in the following year. In that war the onset settled everything. There was no real grip of the opposing forces. The German attack had been so swift, vigorous, and successful that France was knocked out in the first round.
RESULTS OF SUCCESS IN ONSET
The speed with which great armies can be mobilised and hurled against one another has not diminished in the forty odd years which have elapsed since the débâcle. On the contrary, the art of war has been largely concerned in the interval with the vital question, how to get in the first deadly blow.
The military view was, that probably not earlier than the fifteenth day—certainly not later than the twenty-first—a battle would take place which must be of the highest importance, and which might quite well be decisive. It might make ultimate German victory only a matter of time; or it might only determine whether the ensuing campaign was to be waged on French or German soil—whether there was to be a German invasion of France or a Franco-British invasion of Germany. Consequently, if our Expeditionary Force was to render assistance at the critical time, it must reach its position on the frontier within a fortnight of the outbreak of war.
As to the drag of war, the Triple Entente had the advantage, if that stage were ever reached. For the purses of England, France, and Russia were much longer than those of Germany and Austria. It was important, however, to remember that there would be no hope for us in the drag of war, if Germany could deliver a heavy enough blow at the beginning, as she did in 1870.
These were the considerations as to time, which presented themselves to students of the military situation during the breathing space which followed upon the Agadir crisis. The substantial accuracy of this forecast was confirmed by what happened during August and September of last year. In 1914 war was declared by Germany on August 1st. For several days before she had been engaged actively in mobilisation. Three weeks later three important battles—on the road to Metz, at Charleroi, and at Mons[[9]]—were won by the Germans. If it had not been for the unexpected obstacle of Liège the last two engagements would in all probability have been fought at an even earlier date, and in circumstances much more unfavourable to the Franco-British forces. But in the early days of September, instead of the crushing defeat of Sedan, there was the victory of the Marne, and the Germans were forced to retreat to entrenched positions north of the Aisne.[[10]]
