Thus the German plan of campaign was fully developed the second day of the war. It was no longer a secret to the general public, let alone to the French staff, which recognized that it had to deal with this effort of the German wing to come through Belgium. A French movement into Alsace failed. The public reason given for this was that it was a political demonstration in raising the Tricolor over the "lost provinces" dear to the heart of every Frenchman. Another--a military reason--which would seem a more obvious one to the soldier, was a counteroffensive to draw off the force of the German offensive at Liege and Namur, hoping thus, at least, while Liege and Namur were holding the German right in position, to force the German left to the bank of the Rhine. If you will look at the map you will see that this strategy becomes transparently intelligible. Thus early in August the French were trying to turn the German left, and the Germans were preparing to turn the French left. Had the Belgians had anything like an adequate army, had it been skillfully handled; had the fortress of Namur held ten days as many thought it would, the German right might have been held long enough to prevent the Germans forcing a battle on the Marne. By the third week of August, however, the Germans had won their first point. They had broken through Namur, so incapably defended. They had broken the French left, put the British to flight, compelling the withdrawal of the French from German Lorraine, and now the war in the west was being waged entirely on French soil. Technically and strategically the French had been outdone by superior numbers and the incapable defense of Namur, but no decisive battle had been fought. Indeed in a maneuver for positions, the Germans had won. The test was to come on the Marne. Had France been beaten there, she would have been beaten for good. Her army would have been so badly shattered that the Germans would then have been able to have thrown such preponderance of force, in conjunction with the Austrians, against the Russians that Warsaw (and perhaps Petrograd) must have fallen in the first year rather than in the second of the campaign. It would not be going too far to call the Marne the greatest battle in all history, both because of the numbers engaged and the result. Barring a later successful German offensive it decided the fate of France and very likely the fate of the war. All the trench fighting that followed, after all, only nailed down as it were the results of the Marne.
