The Peace of Tilsit made Napoleon the master of Europe with only Great Britain left in the field against him. The subsequent military and political history which led to Napoleon's downfall has no pertinence in the present discussion. What it is essential to recognize is that the German high command in August, 1914, approached a Napoleonic problem in the Napoleonic fashion. In German quarters there had been before the war, and there has been since, a debate as to the comparative advantage of making the first campaign against France or against Russia. The fact that the attack on France failed has doubtless contributed to strengthen the case of those who held the view of the elder Moltke and advocated an eastern offensive. But this is merely an academic discussion. What is of interest to us now is to recognize that Germany did decide to attack France, that she did direct against the republic the first and necessarily the greatest blow she could deliver. It was not until April, 1915, that she actually undertook an attack upon Russia, and then the prospect of a decisive victory, on the Napoleonic order, had practically disappeared. THE ATTACK UPON FRANCE Turning now to the first campaign, the attack upon France, it is to be recognized at the outset that the German purpose was to dispose of France in the military sense for the period of the war by a campaign that should repeat the success of 1870. It was essential that this victory should be achieved before France could profit by Russian activity in the east and before Great Britain could render material military assistance to her French ally. It was equally essential that the blow should be so swift and heavy that it would crush the French before they could equip and organize their great reserves, for whom, thanks to legislative folly and pacifist agitation, there was lacking equipment and arms. For the accomplishment of this great task, Germany counted upon her superior numbers, the greater speed of her mobilization, and the excess of her population over France to give her a decisive advantage. She counted also upon her advantage in heavy artillery and machine guns, on her organization of motor transport, which was to establish new records in invasion. Only in field artillery, in the now famous "seventy-fives," could France claim any advantage. In 1870 Sedan had come four weeks after the first German troops had entered France. For the new campaign the Germans allowed six weeks. For this time German high command reckoned that Russia could be mobilized in the east, and that any incidental Russian success in East Prussia or Silesia would be counterbalanced by the tremendous victories to be won in northern France. Paris itself would be a sufficient counterprize for Posen, Breslau, or Cracow.
