The concentration of this great force proceeded with surprising swiftness; and, in order to lull his foes into confidence, the Emperor delayed his departure from Paris to the last moment possible. As dawn was flushing the eastern sky, on June 12th, he left his couch, after four hours' sleep, entered his landau, and speedily left his slumbering capital behind. In twelve hours he was at Laon. There he found that Grouchy's four cavalry brigades were not sharing in the general advance owing to Soult's neglect to send the necessary orders. The horsemen were at once hurried on, several regiments covering twenty leagues at a stretch and exhausting their steeds. On the 14th the army was well in hand around Beaumont, within striking distance of the Prussian vanguard, from which it was separated by a screen of dense woods. There the Emperor mounted his charger and rode along the ranks, raising such a storm of cheers that he vainly called out: "Not so loud, my children, the enemy will hear you." There, too, on this anniversary of Marengo and Friedland, he inspired his men by a stirring appeal on behalf of the independence of Poles, Italians, the smaller German States, and, above all, of France herself. "For every Frenchman of spirit the time has come to conquer or die."
What, meanwhile, was the position of the allies? An Austro-Sardinian force threatened the south-east of France. Mighty armies of 170,000 Russians and 250,000 Austrians were rolling slowly on towards Lorraine and Alsace respectively; 120,000 Prussians, under Blücher, were cantoned between Liège and Charleroi; while Wellington's composite array of British, German, and Dutch-Belgian troops, about 100,000 strong, lay between Brussels and Mons.[473] The original plan of these two famous leaders was to push on rapidly into France; but the cautious influences of the Military Council sitting at Vienna prevailed, and it was finally decided not to open the campaign until the Austrians and Russians should approach the frontiers of France. Even as late as June 15th we find Wellington writing to the Czar in terms that assume a co-operation of all the allies in simultaneous moves towards Paris—movements which Schwarzenberg had led him to expect would begin about the 20th of June.[474]
From this prolonged and methodical warfare Europe was saved by Napoleon's vigorous offensive. His political instincts impelled him to strike at Brussels, where he hoped that the populace would declare for union with France and severance from the detested Dutch. In this war he must not only conquer armies, he must win over public opinion; and how could he gain it so well as in the guise of a popular liberator?
But there were other advantages to be gained in Belgium. By flinging himself on Wellington and the Prussians, and driving them asunder, he would compel Louis XVIII. to another undignified flight; and he would disorganize the best prepared armies of his foes, and gain the material resources of the Low Countries. He seems even to have cherished the hope that a victory over Wellington would dispirit the British Government, unseat the Ministry, and install in power the peace-loving Whigs.
And this victory was almost within his grasp. While his host drew near to the Prussian outposts south of Charleroi and Thuin, the allies were still spread out in cantonments that extended over one hundred miles, namely, from Liège on Blücher's left to Audenarde on Wellington's right. This wide dispersion of troops, when an enterprising foe was known to be almost within striking distance, has been generally condemned. Thus General Kennedy, in his admirable description of Waterloo, admits that there was an "absurd extension" of the cantonments. Wellington, however, was bound to wait and to watch the three good high-roads, by any one of which Napoleon might advance, namely, those of Tournay, Mons, and Charleroi. The Duke had other causes for extending his lines far to the west: he desired to cover the roads from Ostend, whence he was expecting reinforcements, and to stretch a protecting wing over the King of France at Ghent.
There are many proofs, however, that Wellington was surprised by Napoleon. The narratives of Sir Hussey Vivian and Captain Mercer show that the final orders for our advance were carried out with a haste and flurry that would not have happened if the army had been well in hand, or if Wellington had been fully informed of Napoleon's latest moves.[475] There is a wild story that the Duke was duped by Fouché, on whom he was relying for news from Paris. But it seems far more likely that he was misled by the tidings sent to Louis XVIII. at Ghent by zealous royalists in France, the general purport of which was that Napoleon would wage a defensive campaign.[476] On the 13th June, Wellington wrote: "I have accounts from Paris of the 10th, on which day he [Bonaparte] was still there; and I judge from his speech to the Legislature that his departure was not likely to be immediate. I think we are now too strong for him here." And, in later years, he told Earl Stanhope that Napoleon "was certainly wrong in attacking at all"; for the allied armies must soon have been in great straits for want of food if they had advanced into France, exhausted as she was by the campaign of 1814. "But," he added, "the fact is, Bonaparte never in his life had patience for a defensive war."
[Illustration: PLAN OF THE WATERLOO
CAMPAIGN]
The Duke's forces would, at the outset of the campaign, have been in less danger, if the leaders at the Prussian outposts, Pirch II. and Dörnberg of the King's German Legion, had warned him of the enemy's massing near the Sambre early on the 15th. By some mischance this was not done; and our leader only heard from Hardinge, at the Prussian headquarters, that the enemy seemed about to begin the offensive. He therefore waited for more definite news before concentrating upon any one line.
About 6 p.m. on the 15th he ordered his divisions and brigades to concentrate at Vilvorde, Brussels, Ninove, Grammont, Ath, Braine-le-Comte, Hal, and Nivelles—the first four of which were somewhat remote, while the others were chosen with a view to defending the roads leading northwards from Mons. Not a single British brigade was posted on the Waterloo-Charleroi road, which was at that time guarded only by a Dutch-Belgian division, a fact which supports Mr. Ropes's contention that no definite plan of co-operation had been formed by the allied leaders. Or, if there was one, the Duke certainly refused to act upon it until he had satisfied himself that the chief attack was not by way of Mons or Ath. More definite news reached Brussels near midnight of the 15th, whereupon he gave a general left turn to his advance, namely, towards Nivelles.
Clausewitz maintains that he should already have removed his headquarters to Nivelles; had he done so and hurried up all available troops towards the Soignies-Quatre Bras line, his Waterloo fame would certainly have gained in solidity. A dash of romance was added by his attending the Duchess of Richmond's ball at Brussels on the night of the 15th-16th; lovers of the picturesque will always linger over the scene that followed with its "hurrying to and fro and tremblings of distress"; but the more prosaic inquirer may doubt whether Wellington should not then have been more to the front, feeling every throb of Bellona's pulse.[477]
