It would certainly be necessary for Germany, as well as Austria, to provide troops for coast defences, and also for the frontiers of neutral countries, which might have the temptation, in certain circumstances, to deneutralise themselves at an inconvenient moment, if they were left unwatched. On the north and west were Denmark, Holland, and Belgium, each of which had a small field army, besides garrison and fortress troops which might be turned to more active account upon an emergency. On the south and east were Montenegro, Servia, and Roumania, whose military resources were on a considerable scale, and whose neutrality was not a thing altogether to be counted on, even before the Balkan war[3] had lowered the prestige of Turkey. In addition there was Italy, who although a pledged ally in a defensive war was not likely, for that reason, to consider herself bound to neutrality, benevolent or otherwise, if in her judgment, the particular contingencies which called for her support had not arisen at the outset. [Sidenote: SUPERIORITY OF GERMAN NUMBERS] After taking such precautions as seemed prudent under these heads, Germany would then be obliged to detach for service, in co-operation with the Austrians in Poland, and along the whole eastern border, a sufficient number of army corps to secure substantial superiority over the maximum forces which Russia, hampered by an inadequate railway system and various military considerations,[4] could {257} be expected to bring into the field and maintain there during the first few months of the war. It was reckoned[5] after taking all these things into account, that Germany would have available, for the invasion of France, an army consisting of some ninety divisions--roughly, rather more than a million and three-quarters of men--and that she could maintain this force at its full strength--repairing the wastage of war out of her ample reserves--for a period of at least six months. It was assumed that the Kaiser, relying upon the much slower mobilisation of Russia, would undoubtedly decide to use the whole of this huge force in the west, in the hope that before pressure could begin to make itself felt in the east, France would either have been crushed, as she was in 1870, or so much mangled that it would be possible to send reinforcements of an overwhelming character to make victory secure in Poland.
