ОглавлениеFollowing upon this success, Dumouriez pressed on to what had been, from the first moment of his power at the head of the army, his personal plan—to wit, the invasion of the Low Countries.
To understand why this invasion failed and why Dumouriez thought it might succeed, we must appreciate the military and political situation of the Low Countries at the time. They then formed a very wealthy and cherished portion of the Austrian dominions; they had latterly suffered from deep disaffection culminating in an open revolution, which was due to the Emperor of Austria's narrow and intolerant contempt of religion. From his first foolish policy of persecution and confiscation he had indeed retreated, but the feeling of the people was still strongly opposed to the Government at Vienna. It is remarkable, indeed, and in part due to the pressure of a strongly Protestant and aristocratic state, Holland, to the north of them, that the people of the Austrian Netherlands retained at that time a peculiar attachment to the Catholic religion. The Revolution was quite as anti-Catholic as the Austrian Emperor, but of the persecution of the latter the Belgians (as we now call them) knew something; that of the former they had not yet learnt to dread. It was, therefore, Dumouriez' calculation that, in invading this province of the Austrian power, he would be fighting in friendly territory. Again, it was separated from the political centre of the empire; it was, therefore, more or less isolated politically, and even for military purposes communication with it was not so easy, unless, indeed, Austria could count on a complete co-operation with Prussia, which Power had been for now so long her ruthless and persistent rival.

Favourable, however, as the circumstances appeared for an invasion, two factors telling heavily against the French had to be counted: the first was the formation of their army, the second the spirit of rebellion against any anti-Catholic Government which had given such trouble to Joseph II.
Of these two factors by far the most important was, of course, the first. If the French forces had been homogeneous, in good spirit, and well trained, they might have held what they won; as a fact, they were most unhomogeneous, great portions of them were ill trained, and, worst of all, there was no consistent theory of subordinate command. Men who imagined that subordinate, that is, regimental, command in an army could be erected from below, and that a fighting force could resemble a somewhat lax and turbulent democracy, marched alongside of and were actually incorporated with old soldiers who had spent their whole careers under an unquestioned discipline, and under a subordinate command which came to them they knew not whence, and as it were by fate. The mere mixture of two such different classes of men in one force would have been bad enough to deal with, but what was worse, the political theories of the day fostered the military error of the new battalions though the politicians dared not interfere with the valuable organisation of the old.
The invasion of the Low Countries began with a great, though somewhat informal and unfruitful success, in the victory of Jemappes. It was the first striking and dramatic decisive action which the French, always of an eager appetite for such news, had been given since between forty and fifty years. The success in America against the English, though brilliantly won and solidly founded, had not presented occasions of this character, and Fontenoy was the last national victory which Paris could remember. Men elderly or old in this autumn of 1792 would have been boys or very young men when Fontenoy was fought. The eager generation of the Revolution, with its military appetites and aptitudes, as yet had hardly expected victory, though victory was ardently desired by them and peculiarly suitable to their temper.
It may be imagined, therefore, what an effect the news of Jemappes had upon the political world in Paris. The action was fought just below the town of Mons, a few miles over the frontier, and consisted in a somewhat ill-ordered but successful advance across the River Haine. Whether because the Austrians, with an inferior force, attempted to hold too long a line, or because the infantry and even the new French volunteer battalions, as yet untried by fatigue, proved irresistible in the centre of the movement, Jemappes was a victory so complete that the attempts of apologists to belittle it only serve to enhance its character.
Like many another great and apparently decisive action, however, it bore no lasting fruit. Both the factors of which I have spoken above appeared immediately after this success. Belgium was, indeed, over-run by the French, but in their over-running of it with something like eighty thousand men, they made no attempt to spare the traditions or to conciliate the sympathies of the inhabitants. Hardly was Jemappes won when Mons, the neighbouring fortified frontier town, was at once endowed with the whole machinery of revolutionary government. Church property was invaded and occasionally rifled, and the French paper money, the assignats of which we have heard, poured in to disturb and in places to ruin the excellent commercial system upon which Belgium then as now reposed.
Jemappes was fought upon the 6th of November, 1702. Brussels was entered upon the 14th, and throughout that winter the Low Countries lay entirely in the hands of the French. The Commissioners from the Convention, though endowing Belgium with republican institutions, treated it as a conquered country, and before the breaking of spring, the French Parliament voted its annexation to France. This annexation, the determination of the politicians in Paris that the new Belgian Government should be republican and anti-Catholic, the maltreatment of the Church in the occupied country and the increasing ill discipline and lack of cohesion in his army, left Dumouriez in a position which grew more and more difficult as the new year, 1793, advanced. It must be remembered that this moment exactly corresponded with the execution of the King and the consequent declaration of war by or against France in the case of one Power after another throughout Europe. Meanwhile, it was decided, foolishly enough, to proceed from the difficult occupation of Belgium to the still more difficult occupation of Holland, and the siege of Maestricht was planned.
The moment was utterly ill-suited for such a plan. Every Executive in the civilised world was coalescing openly or secretly, directly or indirectly, against the revolutionary Government. The first order to retreat came upon the 8th of March, when the siege of Maestricht was seen to be impossible, and when the great forces of the Allies were gathered again to attempt what was to be the really serious attack upon the Revolution: something far more dangerous, something which much more nearly achieved success, than the march of the comparatively small force which had been checked at Valmy.
For ten days the French retreat continued, when, upon the 18th of March, Dumouriez risked battle at Neerwinden. His army was defeated.
The defeat was not disastrous, the retreat was continued in fairly good order, but a civilian population understands nothing besides the words defeat and victory; it can appreciate a battle, not a campaign. The news of the defeat, coming at a moment of crisis in the politics of Paris, was decisive; it led to grave doubts of Dumouriez' loyalty to the revolutionary Government, it shattered his popularity with those who had continued to believe in him, while the general himself could not but believe that the material under his command was rapidly deteriorating. Before the end of the month the army had abandoned all its conquests, and Valenciennes, in French territory, was reached upon the 27th. The dash upon Belgium had wholly failed.
At this moment came one of those political acts which so considerably disturb any purely military conspectus of the revolutionary wars. Dumouriez, at the head of his army, which, though in retreat and defeated, was still intact, determined upon what posterity has justly called treason, but what to his own mind must have seemed no more than statesmanship. He proposed an understanding with the enemy and a combined march upon Paris to restore the monarchical government, and put an end to what seemed to him, as a soldier, a perfectly hopeless situation. He certainly believed it impossible for the French army, in the welter of 1793, to defeat the invader. He saw his own life in peril merely because he was defeated. He had no toleration for the rising enthusiasm or delirium of the political theory which had sent him out, and, even before he had reached French territory, his negotiations with Coburg, the Austrian commander, had begun. They lasted long. Dumouriez agreed to put the frontier fortresses of the French into the hands of the enemy as a guarantee and a pledge; and on the 5th of April all was ready for the alliance of the two armed forces.
But just as the treason of Dumouriez is, in the military sense, abnormal and disturbing to any general conspectus of the campaign, so was the action of his army.
The doubtful point of a general command which is political in nature, and may be unpopular with the rank and file, lies, of course, in the attitude of the commanders of units, and these unanimously refused to obey the orders of their chief. It was known that Dumouriez had been summoned to the bar of the Convention, which body had sent commissioners to apprehend him. He had arrested the commissioners, and had handed them over as hostages and prisoners to Coburg. So far from Dumouriez upon the critical day handing over his force to the enemy, or constituting it a part of an allied army to march upon the capital, he was compelled to fly upon the 8th of April; all that disappeared with him, counting many who later deserted back again to the French colours, was less than a thousand men—and these foreign mercenaries.
The consequence of this strange passage upon the political history of the time we have already seen. Its consequence upon the military history of it was indirect but profound. The French forces, such as they were, were still intact, but no general officer could in future be trusted by Paris, and the stimulus which nations in the critical moments of invasion and of danger during foreign war seek in patriotism, in the offering of a high wage to the men and of honours and fortunes to their commanders, was now sought by the French in the singular, novel and abnormal experiment of the Terror. Command upon the frontier throughout 1793 and the first part of 1794, during the critical fourteen months, that is, which decided the fate of the Revolution, and which turned the tide of arms in favour of the French, was a task accomplished under the motive power of capital punishment. A blunder was taken as a proof of treason, and there lay over the ordering of every general movement the threat of the guillotine.
What we have now to follow is somewhat over a year of a struggle thus abnormally organised upon the French side, and finally successful through the genius of a great organiser, once a soldier, now a politician, Carnot. The French succeeded by the unshakable conviction which permitted the political leaders to proceed to all extremity in their determination to save the Revolution; by the peculiar physical powers of endurance which their army displayed, and finally, of course, by certain accidents—for accident will always be a determining factor in war.
The spring of 1793, the months of April and May, form the first crisis of the revolutionary war. The attack about to be delivered is universal, and seems absolutely certain to succeed. With the exception of the rush at Jemappes, where less than thirty thousand Austrians were broken through by a torrent superior in numbers (though even there obviously ill-organised), no success had attended the revolutionary armies. Their condition was, even to the eye of the layman, bad, and to the eye of the expert hopeless. There was no unity apparent in direction, there were vast lesions in the discipline of the ranks like great holes torn in some rotten fabric. Even against the forces already mobilised against it, it had proved powerless, and it might be taken for granted that by an act more nearly resembling police work than a true campaign, the Allies would reach Paris and something resembling the old order be soon restored. What remains is to follow the process by which this expectation was disappointed.
The situation at this moment can best be understood by a glance at the sketch map on p. 178. Two great French advances had been made in the winter of 1792–93; the one a northern advance, which we have just detailed, the over-running of Belgium; the other an eastern advance right up to the Rhine and to the town of Mayence. Both had failed. The failure in Belgium, culminating in the treason of Dumouriez, has been read. On the Rhine (where Mayence had been annexed by the French Parliament just as Belgium had been) the active hostility of the population and the gathering of the organised forces of the Allies had the same effect as had been produced in the Low Countries.
It was on March 21, 1793, that the Prussians crossed the Rhine at Bacharach, and within that week the French commander, Custine, began to fall back. On the first of April he was back again in French territory, leaving the garrison of Mayence, somewhat over twenty thousand men, to hold out as best it could; a fortnight later the Prussians had surrounded the town and the siege had begun.
On the north-eastern front, stretching from the Ardennes to the sea, a similar state of things was developing. There, a barrier of fortresses stood between the Allies and Paris, and a series of sieges corresponding to the siege of Mayence in the east had to be undertaken. At much the same time as the investment of Mayence, on April 9, the first step in this military task was taken by the Allies moving in between the fortress of Condé and the fortress of Valenciennes. Thenceforward it was the business of the Austrians under Coburg, with the Allies that were to reach him, to reduce the frontier fortresses one by one, and when his communications were thus secure, to march upon Paris.
It is here necessary for the reader unacquainted with military history to appreciate two points upon which not a little of contemporary historical writing may mislead him. The first is that both in the Rhine valley and on the Belgian frontier the forces of the Allies in their numbers and their organisation were conceived to be overwhelming. The second is that no competent commander on the spot would have thought of leaving behind him the garrison of even one untaken fortress. It is important to insist upon these points, because the political passions roused by the Revolution are still so strong that men can hardly write of it without prejudice and bias, and two errors continually present in these descriptions of the military situation in the spring of 1793, are, first, that the Allies were weakened by the Polish question, which was then active, and secondly, that the delay of their commanders before the French fortresses was unnecessary.
Both these propositions are put forward with the object of explaining the ultimate defeat of the enemies of the Revolution: both, however great the authority behind them, are unhistorical and worthless. The French success was a military success due to certain military factors both of design and accident, which will appear in what follows. The Allies played their part as all the art of war demanded it to be played; they were ultimately defeated, not from the commission of any such gross and obvious error in policy or strategy as historians with too little comprehension of military affairs sometimes pretend, but from the military superiority of their opponents.
It is true that the Polish question (that is the necessity the Austrian and Prussian Governments were each under of watching that the other was not lessened in importance by the approaching annexations of further Polish territory with the consequent jealousy and mistrust that arose from this between Austria and Prussia) was a very important feature of the moment. But it is bad military history to pretend that this affected the military situation on the Rhine or in the Netherlands.
Every campaign is conditioned by its political object. The political object in this case was to march upon and to occupy Paris. The political object of a campaign once determined, the size and the organisation of the enemy are calculated and a certain force is brought against it. No much larger force is brought than is necessary: to act in such a fashion would be in military art what paying two or three times the price of an article would be in commerce. The forces of the Allies upon the Rhine and in the Netherlands were, in the opinion of every authority of the time, amply sufficient for their purpose; and more than sufficient: so much more than sufficient that the attitude of that military opinion which had to meet the attack—to wit, the professional military opinion of the French republican soldiers, was that the situation was desperate, nor indeed was it attempted to be met save by a violent and, as it were, irrational enthusiasm.
The second point, the so-called "delay" involved in the sieges undertaken by the Allies, proves, when it is put forward, an insufficient acquaintance with contemporary conditions. Any fortress with a considerable garrison left behind untaken would have meant the destruction of the Austrian or Prussian communications, and their destruction at a moment when the Austrian and Prussian forces were actually advancing over a desperately hostile country. Moreover, when acting against forces wholly inferior in discipline and organisation, an untaken fortress is a refuge which one must take peculiar pains to destroy. To throw himself into such a refuge will always stand before the commander of those inferior forces as a last resource. It is a refuge which he will certainly avail himself of ultimately, if it is permitted to him. And when he has so availed himself of it, it means the indefinite survival of an armed organisation in the rear of the advancing invaders. We must conclude, if we are to understand this critical campaign which changed the history of the world, that Coburg did perfectly right in laying siege to one fortress after another before he began what every one expected to be the necessarily successful advance on Paris. The French despair, as one town after another surrendered, is an amply sufficient proof of the excellence of his judgment.
We approach the military problem of 1793, therefore, with the following two fields clear before us:—
1. In the north-east an advance on Paris, the way to which is blocked by a quadrilateral of fortresses: Mons, Maubeuge, Condé, and Valenciennes, with the subsidiary stronghold of Lequesnoy in the neighbourhood of the last. Mons has been in Austrian hands since Dumouriez' retreat; Condé is just cut off from Valenciennes by Coburg's advance, but has not fallen; Valenciennes and the neighbouring Lequesnoy are still intact, and so is Maubeuge. All must be reduced before the advance on Paris can begin. Behind these fortresses is a French army incapable as yet of attacking Coburg's command with any hope of success. Such is the position in the last fortnight of April.
2. Meanwhile, on the Rhine the French garrison in Mayence is besieged; Custine, the French commander in that quarter, has fallen back on the French town of Landau, and is drawing up what are known in history as the Lines of Weissembourg. The accompanying sketch map explains their importance. Reposing upon the two obstacles of the river on the right and the mountains on the left, they fulfilled precisely the same functions as a fortress; and those functions we have just described. Until these lines were carried, the whole of Alsace may be regarded as a fortress defended by the mountains and the river on two sides, and by the Lines of Weissembourg on the third.
A reader unacquainted with military history may ask why the obstruction was not drawn upon the line of the Prussian advance on Paris. The answer is that the presence of a force behind fortifications anywhere in the neighbourhood of a line of communication is precisely equivalent to an obstacle lying right upon those lines. For no commander can go forward along the line of his advance and leave a large undestroyed force close to one side of that line, and so situated that it can come out when he has passed and cut off his communications; for it is by communications that an army lives, especially when it is marching in hostile country.
Strategic situation in early summer of 1793. Mayence besieged, Condé and Valenciennes about to be besieged. Conditions of the double advance on Paris.
Custine, therefore, behind his Lines of Weissembourg, and the besieged garrison in Mayence, correspond to the barrier of fortresses on the north-east and delayed the advance of the Prussians under Wurmser and Brunswick from the Rhine, just as Condé, Valenciennes, and Maubeuge prevented the advance of Coburg on the north-east. Such in general was the situation upon the eastern frontier at the end of that month of April, 1793.
