But it is manifest now that if the Belgian and French frontiers had been properly prepared--as they should have been prepared when the Germans built their strategic railways--with trenches and gun emplacements and secondary and tertiary lines, the Germans would never have got fifty miles into either France or Belgium. They would have been held at Liége and in the Ardennes. Five hundred thousand men would have held them indefinitely. But the Allies had never worked trench warfare; they were unready for it, Germans knew of their unreadiness, and their unreadiness it is quite clear they calculated. They did not reckon, it is now clear that they were right in not reckoning, the Allies as contemporary soldiers. They were going to fight a 1900 army with a 1914 army, and their whole opening scheme was based on the conviction that the Allies would not entrench.

Somebody in those marvellous maxims from the dark ages that seem to form the chief reading of our military experts, said that the army that entrenches is a defeated army. The silly dictum was repeated and repeated in the English papers after the battle of the Marne. It shows just where our military science had reached in 1914, namely, to a level a year before Bloch wrote. So the Allies retreated.

For long weeks the Allies retreated out of the west of Belgium, out of the north of France, and for rather over a month there was a loose mobile war--as if Bloch had never existed. The Germans were not fighting the 1914 pattern of war, they were fighting the 1899 pattern of war, in which direct attack, outflanking and so on were still supposed to be possible; they were fighting confident in their overwhelming numbers, in their prepared surprise, in the unthought-out methods of their opponents. In the "Victorian" war that ended in the middle of September, 1914, they delivered their blow, they over-reached, they were successfully counter-attacked on the Marne, and then abruptly--almost unfairly it seemed to the British sportsmanlike conceptions--they shifted to the game played according to the very latest rules of 1914. The war did not come up to date until the battle of the Aisne. With that the second act of the great drama began.

I do not believe that the Germans ever thought it would come up to date so soon. I believe they thought that they would hustle the French out of Paris, come right up to the Channel at Calais before the end of 1914, and then entrench, produce the submarine attack and the Zeppelins against England, working from Calais as a base, and that they would end the war before the spring of 1915--with the Allies still a good fifteen years behindhand.

I believe the battle of the Marne was the decisive battle of the war, in that it shattered this plan, and that the rest of the 1914 fighting was Germany's attempt to reconstruct their broken scheme in the face of an enemy who was continually getting more and more nearly up to date with the fighting. By December, Bloch, who had seemed utterly discredited in August, was justified up to the hilt. The world was entrenched at his feet. By May the lagging military science of the British had so far overtaken events as to realise that shrapnel was no longer so important as high explosive, and within a year the significance of machine guns, a significance thoroughly ventilated by imaginative writers fifteen years before, was being grasped by the conservative but by no means inadaptable leaders of Britain.

The war since that first attempt--admirably planned and altogether justifiable (from a military point of view, I mean)--of Germany to "rush" a victory, has consisted almost entirely of failures on both sides either to get round or through or over the situation foretold by Bloch. There has been only one marked success, the German success in Poland due to the failure of the Russian munitions. Then for a time the war in the East was mobile and precarious while the Russians retreated to their present positions, and the Germans pursued and tried to surround them. That was a lapse into the pre-Bloch style. Now the Russians are again entrenched, their supplies are restored, the Germans have a lengthened line of supplies, and Bloch is back upon his pedestal so far as the Eastern theatre goes.

Bloch has been equally justified in the Anglo-French attempt to get round through Gallipoli. The forces of the India Office have pushed their way through unprepared country towards Bagdad, and are now entrenching in Mesopotamia, but from the point of view of the main war that is too remote to be considered either getting through or getting round; and so too the losses of the German colonies and the East African War are scarcely to be reckoned with in the main war. They have no determining value. There remains the Balkan struggle. But the Balkan struggle is something else; it is something new. It must be treated separately. It is a war of treacheries and brags and appearances. It is not a part of, it is a sequence to, the deadlock war of 1915.

But before dealing with this new development of the latter half of 1915 it is necessary to consider certain general aspects of the deadlock war. It is manifest that the Germans hoped to secure an effective victory in this war before they ran up against Bloch. But reckoning with Bloch, as they certainly did, they hoped that even in the event of the war getting to earth, it would still be possible to produce novelties that would sufficiently neutralise Bloch to secure a victorious peace. With unexpectedly powerful artillery suddenly concentrated, with high explosives, with asphyxiating gas, with a well-organised system of grenade throwing and mining, with attacks of flaming gas, and above all with a vast munition-making plant to keep them going, they had a very reasonable chance of hacking their way through.

Against these prepared novelties the Allies have had to improvise, and on the whole the improvisation has kept pace with the demands made upon it. They have brought their military science up to date, and to-day the disparity in science and equipment between the antagonists has greatly diminished. There has been no escaping Bloch after all, and the deadlock, if no sudden peace occurs, can end now in only one thing, the exhaustion in various degrees of all the combatants and the succumbing of the most exhausted. The idea of a conclusive end of the traditional pattern to this war, of a triumphal entry into London, Paris, Berlin or Moscow, is to be dismissed altogether from our calculations. The end of this war will be a matter of negotiation between practically immobilised and extremely shattered antagonists.

There is, of course, one aspect of the Bloch deadlock that the Germans at least have contemplated. If it is not possible to get through or round, it may still be possible to get over. There is the air path.
