A General Sketch of the European War Part 9

Then he will draw up his square so that its various bodies all face towards the average direction from which the blow may come.

The SIZE of his square--which is of great importance to the result--he makes as restricted as possible, _subject to two prime conditions_. These conditions are:--

First, that there shall be room for the troops composing each corner to be deployed--that is, spread out for fighting. Secondly, that there shall be room between any two corners (A and C, for instance) for a third corner (D, for instance) to move in between them and spread out for fighting in support of them. He makes his square as close and restricted as possible, because his success depends--as will be seen in a moment--upon the rapidity with which any one corner can come up in support of the others. But he leaves enough room for the full numbers to spread out for fighting, because otherwise he loses in efficiency; and he leaves room enough between any two squares for a third one to come in, because the whole point of the formation is the aid each corner can bring to the others.

In this posture he awaits the enemy.

That enemy will necessarily come on in a lengthy line, lengthy in proportion to the number of his units. For it is essential to the general commanding _superior_ numbers to make the _whole_ of the superior numbers tell, and this can only be done if they march along parallel roads, and these roads are sufficiently wide apart for the various columns to have plenty of room to deploy--that is, to spread out into a fighting line--when the shock comes.

[Ill.u.s.tration: Sketch 23.]

This extended line of Black marching thus against White strikes White first upon some one corner of his square. Suppose that corner to be corner A. Then the position when contact is established and the first serious fighting begins is what you will observe in the above diagram.

A is the corner (now spread out for fighting) which gets the first shock.

Note you (for this is the crucial point of the whole business) that upon the exposed corner A will fall a very dangerous task indeed. A will certainly be attacked by forces superior to itself. Normally forces more than half as large again as A will be near enough to A to concentrate upon him in the first shock. The odds will be at least as much as five to three, the Black units, 4, 5, and 6, will be right on A, and 3 and 7 will be near enough to come in as well in the first day or two of the combat, while possibly 2 may have a look in as well.

A, thus tackled, has become what may be called "the _operative corner_ of the square." It is his task "to retreat and hold the enemy" while B, C, and D, "the ma.s.ses of manoeuvre," swing up. But under that simple phrase "operative corner" is hidden all the awful business of a fighting retreat: it means leaving your wounded behind you, marching night and day, with your men under the impression of defeat; leaving your disabled guns behind you, keeping up liaison between all your hurrying, retreating units, with a vast force pressing forward to your destruction. A's entire force is deliberately imperilled in order to achieve the success of the plan as a whole, and upon A's tenacity, as will be seen in what follows, the success of that plan entirely depends.

[Ill.u.s.tration: Sketch 24.]

Well, while A is thus retreating--say, from his old position at A_1 on the foregoing diagram to such a position as A_2, with Black swarming up to crush him--the other corners of the square, B, C, and D, receive the order to "swing"--that is, to go forward inclining to the left or the right according to the command given.

Mark clearly that, until the order is given, the general commanding Black cannot possibly tell whether the "swing" will be directed to the left or to the right. Either B will close up against A, C spread out farther to the left, and D come in between A and C (which is a "swing" to the left) as in Sketch 25, or C will close up against A, B will spread well out to the right, and D come up between A and B, as in Sketch 26 (which is a "swing" to the right).

[Ill.u.s.tration: Sketch 25.]

Until the "swing" actually begins, Black, the enemy, cannot possibly tell whether it is his left-hand units (1 to 8) or his right-hand units (9 to 16) which will be affected. One of the two ends of his line will have to meet White's concentrated effort; the other will be left out in the cold. Black cannot make dispositions on the one hypothesis or on the other. Whichever he chose, White would, of course, swing the other way and disconcert him.

Black, therefore, has to keep his line even until he knows which way White is going to swing.

[Ill.u.s.tration: Sketch 26.]

Let us suppose that White swings to the left.

Mark what follows. The distances which White's units have got to go are comparatively small. B will be up at A's side, and so will D in a short time after the swing is over, and when the swing is completed, the position is after this fas.h.i.+on. Black's numbers, 1 to 9 inclusive, find themselves tackled by all Black's twelve. There is a superiority of number against Black on his right, White's left, and the remaining part of Black's line (10 to 16 inclusive), is out in the cold.

If it were a tactical problem, and all this were taking place in a small field, Black's left wing, 10-16, would, of course, come up at once and redress the balance. But being a strategical problem, and involving very large numbers and very great distances, Black's left wing, 10-16, can do nothing of the kind. For Black's left wing, 10-16, _cannot possibly get up in time_. Long before it has arrived on the scene, White's 12 will have broken Black's 9 along Black's right wing.

[Ill.u.s.tration: Sketch 27.]

There are three elements which impose this delay upon Black's left wing.

First, to come round in aid of the right wing means the marching forward of one unit after another, so that each shall overlap the last, and so allow the whole lot to come up freely. This means that the last unit will have to go forward six places before turning, and that means several days' marching. For with very large bodies, and with a matter of 100 miles to come up, all in one column, it would be an endless business (Sketch 28).

[Ill.u.s.tration: Sketch 28.]

Next you have the delay caused by the _conversion of direction_ through a whole right angle. That cause of delay is serious. For when you are dealing with very large bodies of men, such as half a dozen army corps, to change suddenly from the direction S (see Sketch 29) for which your Staff work was planned, and to break off at a moment's notice in direction E, while you are on the march towards S, is impossible. You have to think out a whole new set of dispositions, and to re-order all your great body of men. White was under no such compulsion, for though he had to swing, the swing faced the same general direction as his original dispositions. And the size of the units and the distances to be traversed--the fact that the problem is strategical and not tactical--is the essence of the whole thing. If, for instance, you have (as in Sketch 30) half a dozen, not army corps, but mere battalions of 1,000 men, deployed over half a dozen miles of ground, AB, and advancing in the direction SS, and they are suddenly sent for in the direction E, it is simple enough. You form your 6,000 men into column; in a few hours' delay they go off in the direction E, and when they get to the place where they are wanted, the column can spread out quickly again on the front CD, and soon begin to take part in the action. But when you are dealing with half a dozen army corps--240,000 men--it is quite another matter. The turning of any one of these great bodies through a whole right angle is a lengthy business. You cannot put a quarter of a million men into one column--they would take ages to deploy--so you must, as we have seen, make each unit of them overlap the next before the turn can begin.

[Ill.u.s.tration: Sketch 29.]

[Ill.u.s.tration: Sketch 30.]

Nor is that all the delay involved. It would never do for these six separate corps to come up in driblets and get defeated in detail; 10, 11, and 12 will have to wait until 13, 14, 15, and even 16, have got up abreast of them--and that is the third cause of delay.

Here are three causes of delay which, between them and acc.u.mulated, have disastrous effect; and in general we may be certain that where very large bodies and very extensive stretches of territory are concerned, that wing of Black which has been left out in the cold can never come up in time to retrieve the situation created by White's twelve pinning Black's engaged wing of only nine.

If the square has worked, and if the twelve White have pinned the right-hand wing of Black, 1 to 9 inclusive, there is nothing for Black to do but to order his right wing, 1 to 9, to retreat as fast as possible before superior numbers, and to order his left wing, 10 to 16, to fall back at the same time and keep in line; and you then have the singular spectacle of twelve men compelling the retreat of and pursuing sixteen.

_That is exactly what happened in the first three weeks of active operations in the West. The operative corner A in the annexed diagram was the Franco-British force upon the Sambre. The retirement of that operative corner and its holding of the enemy was what is called in this country "The Retreat from Mons." BB are the "ma.s.ses of manoeuvre"

behind A. The swinging up of these ma.s.ses involving the retirement of the whole was the Battle of the Marne._

[Ill.u.s.tration: Sketch 31.]

Now, it is evident that in all this everything depends upon the tenacity and military value of the operative corner, which is exposed and sacrificed that the whole scheme of the Open Square may work.

If that operative corner is destroyed as a force--is overwhelmed or dispersed or surrounded--while it is fighting its great odds, the whole square goes to pieces. Its centre is penetrated by the enemy, and the army is in a far worse plight than if recourse had never been had to the open strategic square at all. For if the operative corner, A, is out of existence before the various bodies forming the "manoeuvring ma.s.s" behind it have had time to "swing," then the enemy will be right in their midst, and destroying, in overwhelming force, these remaining _separated_ bodies in detail.

It was here that the German strategic theory contrasted so violently with the French. The Germans maintained that an ordeal which Napoleon might have been able to live through with his veterans and after fifteen years of successful war, a modern conscript army, most of its men just taken from civilian life and all of short service, would never endure. They believed the operative corner would go to pieces and either be pounded to disintegration, or outflanked, turned, and caught in the first days of the shock before the rest of the square had time to "work." The French believed the operative corner would stand the shock, and, though losing heavily, would remain in being.

They believed that the operative corner of the square would, even under modern short service and large quasi-civilian reserve conditions, remain an army. They staked their whole campaign upon that thesis, and they turned out to be right. But they only just barely won through, and by the very narrowest margin. Proving right as they did, however, the success of their strategical theory changed the whole course of the war.

With this contrast of the great opposing theories considered, I come to the conclusion of my Second Part, which examines the forces opposed. I will now turn to the Third Part of my book, which concerns the first actual operations from the Austrian note to the Battle of the Marne.

FOOTNOTES:

[1] Thus, after these lines were written, I had occasion in _Land and Water_ to estimate the garrison of Przemysl before the figures were known. The element wherewith to guide one's common sense was the known perimeter to be defended; and arguing from this, I determined that a minimum of not less than 100,000 men would capitulate. I further conceived that the total losses could hardly be less than 40,000, and I arrived at an original force of between three and four corps.

PART III.

THE FIRST OPERATIONS.

In any general view of the great war which aims both at preserving proportion between its parts, and at presenting especially the main lines in relief, the three weeks between the German sudden forcing of war and the seventeen or eighteen days between the English declaration and the main operations upon the Sambre, will have but a subsidiary importance. They were occupied for at least half the period in the mobilization of the great armies. They were occupied for the second half of the period in the advance across the Rhine of German numbers greatly superior to the Allies, and also through the plain of Northern Belgium. The operation, as calculated by the German General Staff, was delayed by but a very few days--one might almost say hours--by the hastily improvised resistance of Liege, and the imperfect defence of their country which was all the Belgian forces, largely untrained, could offer.

We must, therefore, pa.s.s briefly enough over that preliminary period, though the duty may be distasteful to the reader, on account of the very exaggerated importance which its operations took, especially in British eyes.

For this false perspective there were several reasons, which it is worth while to enumerate, as they will aid our judgment in obtaining a true balance between these initial movements and the great conflicts to which they were no more than an introduction.

1. War, as a whole, had grown unfamiliar to Western Europe. War on such a scale as this was quite untried. There was nothing in experience to determine our judgment, and after so long a peace, during which the habits of civil life had ceased to be conventioned and had come to seem part of the necessary scheme of things, the first irruption of arms dazzled or confounded the imagination of all.

2. The first shock, falling as it did upon the ring fortress of Liege, at once brought into prominence one of the chief questions of modern military debate, the value of the modern ring fortress, and promised to put to the test the opposing theories upon this sort of stronghold.

3. The violation of Belgian territory, though discounted in the cynical atmosphere of our time, when it came to the issue was, without question, a stupendous moral event. It was the first time that anything of this sort had happened in the history of Christian Europe.

Historians unacquainted with the spirit of the past may challenge that remark, but it is true. One of the inviolable conventions, or rather sacred laws, of our civilization was broken, which is that European territory not involved in hostilities by any act of its Government is inviolable to opposing armies. The Prussian crime of Silesia, nearly two centuries before, the succeeding infamies of 1864, and the forgery of the Ems dispatch, the whole proclaimed tradition of contempt for the sanct.i.ties of Christendom, proceeding from Frederick the Great, had indeed accustomed men to successive stages in the decline of international morals; but nothing of the wholly crude character which this violation of Belgium bore was to be discovered in the past, even of Prussia, and posterity will mark it as a curious term and possibly a turning-point in the gradual loss of our common religion, and of the moral chaos accompanying that loss.
