Sketch 54.
There lay in the gap formed by this untoward tardiness in the British retirement, at the point M, the fortress of Maubeuge. It was garrisoned by French reserves, or Territorial troops, not of the same quality as the active army, and its defensive power was, even if the old ring of fortress theory had proved sound, of very doubtful order.
The French 5th Army being no longer present to support the British right, but having fallen back behind the alignment of that right, General Sir John French had no support for what should have been his secure flank save this fortress of Maubeuge, and it will be evident from the above diagram that the enemy, should he succeed in outflanking the British line, would compel it to fall back within the ring of forts surrounding Maubeuge. To avoid destruction it would have no alternative but to do that. For, counting the forces in front of it and the forces trying to get round its back, it was fighting odds of two to one.
Maubeuge was a stronghold that had played a great part in the revolutionary war. Its resistance in the month of October 1793 had made possible the French victory of Wattigines, just outside its walls, and had, perhaps, done more than any other feat of arms in that year to save the French Revolution from the allied governments of Europe. It was, indeed, full of historic memories, from the moment when Cæsar had defeated the Nervii upon the Sambre just to the west of the town (his camp can still be traced in an open field above the river bank) to the invasion of 1815.
But this rôle which it had played throughout French history had not led to any illusion with regard to the rôle it might play in any modern war; and at the best Maubeuge, in common with the other ill-fortified points of the Belgian frontier, suffered from the only error—and that a grave one—which their thorough unnational political system had imposed upon the military plan of the French. This error was the capital error of indecision. No consistent plan had been adopted with regard to the fortification of the Belgian frontier.
The French had begun, after the recuperation following upon the war of 1870, an elaborate and very perfect system of fortification along their German frontier—that is, along the new frontier which divided the annexed territory of Alsace-Lorraine from the rest of the country. They had taken it for granted that the next German attempt would be made somewhere between Longwy and Belfort. And they had spent in this scheme of fortification, first and last, the cost of a great campaign. They had spent some three hundred million pounds; and it will be possible for the reader to gauge the magnitude of this effort if he will consider that it was a military operation more costly than was the whole of the South African War to Great Britain, or of the Manchurian War to Russia. The French were wise to have undertaken this expense, because it had hitherto been an unheard-of offence against European morals that one nation in Christendom should violate the declared neutrality of another. And the attack upon Belgium as a means of invading France by Germany had not then crossed the mind of any but a few theorists who had, so to speak, "marched ahead" of the rapid decline in our common religion which had marked now three generations.
But when the French had completed this scheme of fortification, Europe heard it proposed by certain authorities in Prussia that, as the cost of invading France through the now fortified zone would be considerable, the German forces should not hesitate to originate yet another step in the breakdown of European morality, and to sacrifice in their attack upon France the neutrality of Belgium, of which Prussia was herself a guarantor.
Men have often talked during this war, especially in England, as though the crime accompanying Prussian activities in the field were normal to warfare; and this error is probably due to the fact that war upon a large scale has never come home to the imagination of the country, and that it is without experience of invasion.
Yet it is of the very first importance to appreciate the truth that Prussia in this campaign has postulated in one point after another new doctrines which repudiate everything her neighbours have held sacred from the time when a common Christianity first began to influence the states of Europe. The violation of the Belgian territory is on a par with the murder of civilians in cold blood, and after admission of their innocence, with the massacre of priests, and the sinking without warning of unarmed ships with their passengers and crews. To regard these things as something normal to warfare in the past is as monstrous an historical error as it would be to regard the reign of terror during the French Revolution as normal to civil disputes within the State. And to appreciate such a truth is, I repeat, of especial moment to the understanding of the mere military character of the campaign. For if the violation of Belgium in particular had not been the unheard of thing it was, the fortification of the Franco-Belgian frontier with which we are here concerned would have had a very different fortune.
