If Paris could be reached by the strongest of the chain of armies in eight days, then the mobilisation of the French reserves would still be incomplete. Under the most favourable conditions, and even without the disturbance of invasion, that mobilisation takes a fortnight. Given a sudden and successful invasion with the resultant upset of communications and the mobilisation could never be completed. All, therefore, that the 1,680,000 men forming the invading hosts[9] would have to encounter would be the effectives of the French regular forces, less than half the number of the invaders. When we speak of twenty-eight army corps moving in echelon, approximately like so many squares placed diagonally corner to corner, it is as well not to forget that such a chain of masses may assume quite sinuous and snake-like variations and yet remain perfectly intact and strong. For example, the head of the chain might be wound round and pivot upon Paris, and the rest of the chain extended across France in curves. This gigantic military boa-constrictor might therefore crush the heart out of France, while the defenders of the country remained helpless in its toils. Such in brief was the daring and ambitious scheme conceived and worked out by the German General Headquarters Staff, and worked out in the most minute detail. It will be seen from this summary that so far as its broad military features are concerned, the plan promised an almost certainly successful enterprise. There were concealed in its calculations, nevertheless, fatal flaws. What they were will appear in the course of the present narrative. Meanwhile it is necessary to add that possible opposition from Belgium had not been overlooked; nor the possibility, consequent upon that opposition, of intervention by Great Britain. From the military standpoint, however, it was never calculated that any British military force would be able to land either in France or in Belgium promptly enough to save the French army from disaster. In any event, such a force would be, from its limited numbers, comparatively unimportant. FOOTNOTES: [1] Despatch from Sir John French to Earl Kitchener of September 17th, 1914.

This statement was circulated by Reuter's correspondent at Paris on what was asserted to be high diplomatic authority. Such a sum sounds incredible, though as a _pretext_ it might possibly have been put forward. [3] Simon: _The Emperor William and his Reign._ [4] This phrase is that of General F. von Bernhardi.
