This second phase of the action at Waterloo began in the neighbourhood of four o'clock.

It is true that the arriving Prussians had not yet debouched from the screen of wood that hid them two and a half miles away to the east, but at that hour (four o'clock) the heads of their columns were all ready to debouch, and the delay between their actual appearance upon the field and the beginning of the second half of the battle was not material to the result.

That second half of the action began with a series of great cavalry charges which the Emperor had not designed, and which, even as he watched them, he believed would be fatal to him. As spectacles, these famous rides presented the most awful and memorable pageant in the history of modern war; as tactics they were erroneous, and grievously erroneous.

Before this second phase of the battle was entered it was easily open to Napoleon, recognising the Prussians advancing and catching no sight of Grouchy, to change his plan, to abandon the offensive, to stand upon the defensive along the height which he commanded, there to await Grouchy, and, if Grouchy still delayed, to maintain the chances of an issue which might at least be negative, if he could prevent its being decisively disastrous.

But even if such a conception had pa.s.sed through the Emperor's mind, military science was against it. If ever those opposed to him had full time to concentrate their forces he would, even with the reinforcement of Grouchy, be fighting very nearly two to one. His obvious, one might say his necessary, plan was to break Wellington's line, if still it could be broken, before the full pressure of the arriving Prussians should be felt.

Short of that, there could be nothing but immediate or ultimate disaster.

We shall see how, much later in the action, yet another opportunity for breaking away, and for standing upon the defensive, or for retreating, was, in the opinion of some critics, offered to the Emperor by fate.

But we shall see how, upon that second and later occasion in the day, his advantage in so doing was even less than it was now between this hour of half-past three and four o'clock, when he determined to renew the combat.

He first sent orders to Ney to make certain of La Haye Sainte, to clear the enemy from that stronghold, which checked a direct a.s.sault upon the centre, and then to renew the general attack.

La Haye Sainte was not taken at this first attempt. The French were repelled; the skirmishers, who were helping the direct attack by mounting the slope upon its right, were thrown back as well, and after this unsuccessful beginning of the movement the guns were called upon to prepare a further and more vigorous a.s.sault upon a larger scale. Not only the first great battery of eighty guns, but many of the batteries to the west of the Brussels road (which had hitherto been turned upon Hougomont and the English guns behind that position) were now directed upon the centre of the English line, and there broke out a cannonade even more furious than the one which had opened the action at one o'clock. Men trained in a generation's experience of war called it the most furious artillery effort of their time; and never, perhaps, even in the career of the Gunner who was now in the last extremity of his fate, had guns better served him.

Under the battering of that discharge the front of Wellington's command was partially withdrawn behind the cover of the ridge. A stream of wounded, mixed with not a few men broken and flying, began to swell northward up the Brussels road; and Ney, imagining from such a sight that the enemy's line wavered, committed his capital error, and called upon the cavalry to charge.

Wellington's line was not wavering. For the ma.s.s of the French cavalry to charge at such a moment was to waste irreparably a form of energy whose high potential upon the battlefield corresponds to a very rapid exhaustion, and which, invaluable against a front shaken and doubtful, is useless against a front still solid.

It was not and could not have been the Emperor who ordered that false step. It is even uncertain whether the whole body of hors.e.m.e.n that moved had been summoned by Ney, or whether the rearmost did not simply follow the advance of their fellows. At any rate, the great group of mounted men[21] which lay in reserve behind the First Army Corps, and to the west of the road, pa.s.sed in its entirety through the infantry, and began to advance at the trot down the valley for the a.s.sault upon the opposite slope.

I repeat, it is not certain whether Ney called upon all this ma.s.s of cavalry and deliberately risked the waste of it in one blow. It is more probable that there was some misunderstanding; that Desnoettes' command, which was drawn up behind Milhaud's, followed Milhaud's, under the impression that a general order had been given to both; that Ney, seeing this extra body of horse following, imagined Napoleon to have given it orders. At any rate, Napoleon never gave such orders, and, from the height upon which he stood, could not have seen the first execution of them, for the first advance of that cavalry was hidden from him by a slight lift of land.

There were 5000 mounted men drawn up in the hollow to the west of the Brussels road for the charge. It was not until they began to climb the slope that Napoleon saw what numbers were being risked, and perceived the full gravity of Ney's error.

To charge unshaken infantry in this fashion, and to charge it without immediate infantry support, was a thing which that master of war would never have commanded, and which, when he saw it developing under the command of his lieutenant, filled him with a sense of peril. But it was too late to hesitate or to change the disposition of this sudden move. The 5000 climbed at a slow and difficult trot through the standing crops and the thick mud of the rising ground, suffered--with a moment's wavering--the last discharge of the British guns, and then, on reaching the edge of the plateau, spurred to the gallop and charged.

It was futile. They pa.s.sed the line of guns (the gunners had orders to abandon their pieces and to retire within the infantry squares); they developed, in too short a start, too slight an impetus; they seethed, as the famous metaphor of that field goes, "like angry waves round rocks"; they lashed against every side of the squares into which the allied infantry had formed. The squares stood.

Wellington had had but a poor opinion of his command. It contained, indeed, elements more diverse and raw material in larger proportion than ever he, or perhaps any other general of the great wars, had had to deal with, but it was infantry hitherto unshaken; and the whole conception of that false movement, the whole error of that cavalry action, lay in the idea that the allied line had suffered in a fashion which it had been very far from suffering. Nothing was done against the squares; and the firmest of them, the nucleus of the whole resistance, were the squares of British infantry, three deep, against which the furious close-sabring, spurring, and fencing of sword with bayonet proved utterly vain. Upon this ma.s.s of hors.e.m.e.n moving tumultuous and ineffectual round the islands of foot resisting their every effort, Uxbridge, gathering all his cavalry, charged, and 5000 fresh horse fell upon the French lancers and cuira.s.siers, already shredded and lessened by grape at fifty yards and musket fire at ten. This countercharge of Uxbridge's cleared the plateau.

The French hors.e.m.e.n turned bridle, fled to the hollow of the valley again, and the English gunners returned to their pieces. The whole fury of the thing had failed.

But it had failed only for a moment. What remained of the French horse reformed and once again attempted to charge. Once again, for all their gravely diminished numbers, they climbed the slope; once again the squares were formed, and the torment of hors.e.m.e.n round about them struck once more.

Seen from the point where Napoleon stood to the rear of his line, the high place that overlooked the battlefield, it seemed to eyes of less genius than his own that this second attempt had succeeded. Indeed, its fierce audacity seemed to other than the French observers at that distance to promise success. The drivers of the reserve batteries in the rear of Wellington's line were warned for retreat, and Napoleon, reluctant, but pressed by necessity, seeing one chance at last of victory by mere shock, himself sent forward a reserve of horse to support the distant cuira.s.siers and lancers. He called upon Kellerman, commanding the cavalry of the Guard, to follow up the charge.

He knew how doubtful was the success of this last reinforcement, for he knew how ill-judged had been Ney's first launching of that great ma.s.s of horse at an unbroken enemy; but, now that the thing was done, lest, unsupported, it should turn to a panic which might gain the whole army, he risked almost the last mounted troops he had and sent them forward, acting thus like a man throwing good money after bad for fear that all may be lost.

A better reason still decided Napoleon so to risk a very desperate chance, and to hurl Kellerman upon the heels of Milhaud. That reason was the advent, now accomplished, of the Prussians upon his right, and the necessity, imperative and agonised, of breaking Wellington's line before the whole strength of the newcomers should be felt upon the French flank and rear.

Let us turn, then, and see how far and with what rapidity the Prussians at this moment--nearly half-past five o'clock--had accomplished their purpose.

Of the four Prussian corps d'armee bivouacked in a circle round Wavre, and unmolested, as we have seen, by Grouchy, it was the fourth, that of Bulow, which was given the task of marching first upon the Sunday morning to effect the junction with Wellington. It lay, indeed, the furthest to the east of all the Prussian army,[22] but it was fresh to the fight, for it had come up too late to be engaged at Ligny. It was complete; it was well commanded.

The road it had to traverse was not only long, but difficult. The pa.s.sage of the river Lasne had to be effected across so steep a ravine and by so impa.s.sable a set of ways that the modern observer, following that march as the present writer has followed it, after rain and over those same fields and roads, is led to marvel that it was done in the time which Blucher's energy and the traditional discipline of the Prussian soldiers found possible. At any rate, the heads of the columns were on the Waterloo edge of the Wood of Fischermont[23] (or Paris) before four o'clock, and ready to debouch. Wellington had expected them upon the field by two o'clock at latest. They disappointed him by two hours, and nearly three, but the miracle is that they arrived when they did; and it is well here to consider in detail this feat which the Fourth Prussian Army Corps had accomplished, for it is a matter upon which our historians of Waterloo are often silent, and which has been most unfortunately neglected in this country.

The Fourth Prussian Army Corps, under Bulow, lay as far east as Liege when, on the 14th of June, Napoleon was preparing to cross the Sambre.

Its various units were all in the close neighbourhood of the town, so none of them were spared much of the considerable march which all were about to undertake to the west; even its most westward detachment was no more than three miles from Liege city.

Bulow should have received the order to march westward at half-past ten on the morning of the 15th. The order, as we have seen in speaking of Ligny, was not delivered till the evening of that day. The Fourth Army Corps was told to concentrate in the neighbourhood of Hannut and a little east of that distant point. The corps, as a whole, did not arrive until the early afternoon of Friday the 16th.

It is from this point--Hannut--that the great effort begins.

Bulow, it must be remembered, commanded no less than 32,000 men. The fatigues and difficulties attendant upon the progress of such a body, most of it tied to one road, will easily be appreciated.

During the afternoon of the 16th, while Ligny was being fought, he advanced the whole of this body to points immediately north and east of Gembloux. Not a man, therefore, of his great command had marched less than twenty miles, many must have marched over twenty-five, upon that Friday afternoon.

Then followed the night during which the other three defeated corps fell back upon Wavre.

That night was full of their confused but unmolested retreat. With the early morning of the Sat.u.r.day Bulow's 32,000 fell back along a line parallel to the general retirement, and all that day they were making their way by the cross-country route through Welhain and Corroy to Dion Le Mont.

This task was accomplished through pouring rain, by unpaved lanes and through intolerable mud, over a distance of close on seventeen miles for the hardest pushed of the troops, and not less than thirteen for those whom the accident of position had most spared.

The greater part of the Fourth Corps had spent the first night in the open; all of it had spent the second night upon the drenched ground. Upon the _third_ day, the Sunday of Waterloo, this force, though it lies furthest from the field of Waterloo of all the Prussian forces, is picked out to march first to the aid of Wellington, because it as yet has had no fighting and is supposed to be "fresh." On the daybreak, therefore, after bivouacking in that dreadful weather, Bulow's force is again upon the move. It does not get through Wavre until something like eight o'clock, and the abominable conditions of the march may be guessed from the fact that its centre did not reach St Lambert until one o'clock, nor did the last brigade pa.s.s through that spot until three o'clock. Down the steep ravine of the Lasne and up on the westward side of it was so hard a business that, as we have seen, the brigades did not begin to debouch from the woods at the summit until after four o'clock. It was not until after five o'clock that the last brigade, the 14th, had come up in line with the rest upon the field of Waterloo, having moved, under such abominable conditions of slow, drenched marching, another fifteen miles.

In about forty-eight hours, therefore, this magnificent piece of work had been accomplished. It was a total movement of over fifty miles for the average of the corps--certainly more than sixty for those who had marched furthest--broken only by two short nights, and those nights spent in the open, one under drenching rain. The whole thing was accomplished without appreciable loss of men, guns, or baggage, and at the end of it these men put up a fight which was the chief factor in deciding Waterloo.

Such was the supreme effort of the Fourth Prussian Army Corps which decided Waterloo.

There are not many examples of endurance so tenacious and organisation so excellent in the moving so large a body under such conditions in the whole history of war.

When the Fourth Prussian Corps debouched from the Wood of Fischermont and began its two-mile approach towards his flank, Napoleon, who had already had it watched by a body of cavalry, ordered Lobau with the Sixth French Army Corps, or rather with what he had kept with him of the Sixth Army Corps, to go forward and check it.

It could only be a question of delay. Lobau had but 10,000 against the 30,000 which Bulow could ultimately bring against him when all his brigades had come up; but delay was the essential of the moment to Napoleon. To ward off the advancing Prussian pressure just so long as would permit him to carry the Mont St Jean was his most desperate need.

Lobau met the enemy, three to two, in the hollow of Plancenoit,[24] was turned by such superior numbers, and driven from the village.

All this while, during the Prussian success which brought that enemy's reinforcement nearer and nearer to the rear of the French army and to the Emperor's own standpoint, the wasted though magnificent action of the French cavalry was continuing against Wellington's right centre, west of the Brussels road. Kellerman had charged for the third time; the plateau was occupied, the British guns abandoned, the squares formed. For the third time that furious seething of horse against foot was seen from the distant height of the Belle Alliance. For the third time the sight carried with it a deceptive appearance of victory. For the third time the cavalry charge broke back again, spent, into the valley below. Ney, wild as he had been wild at Quatre Bras, failing in judgment as he had failed then, shouted for the last reserve of horse, and forgot to call for that 6000 untouched infantry, the bulk of Reille's Second Corps, which watched from the height of the French ridge the futile efforts of their mounted comrades.

Folly as it was to have charged unbroken infantry with horse alone, the charges had been so repeated and so tenacious that, _immediately_ supported by infantry, they might have succeeded. If those 6000 men of Reille's, the ma.s.s of the Second Army Corps, which stood to arms unused upon the ridge to the west of the Brussels road, had been ordered to follow hard upon the last cavalry charge, Napoleon might yet have s.n.a.t.c.hed victory from such a desperate double strain as no general yet in military history has escaped. He might conceivably have broken Wellington's line before that gathering flood of Prussians to the right and behind him should have completed his destruction.

But the moment was missed. Reille's infantry was not ordered forward until the defending line had had ample time to prepare its defence; until the English gunners were back again at their pieces, and the English squares once more deployed and holding the whole line of their height.

It is easy to note such errors as we measure hours and distances upon a map. It is a wonderment to some that such capital errors appear at all in the history of armies. Those who have experience of active service will tell us what the intoxication of the cavalry charges meant, of what blood Ney's brain was full, and why that order for the infantry came too late.

Of the 6000 infantry which attempted so belated a charge, a quarter was broken before the British line was reached, and that a.s.sault, in its turn, failed.

At this point in the battle, somewhat after six o'clock, two successes on the part of the French gave them an opportunity for their last disastrous effort, and introduced the close of the tragedy.

The first was the capture of La Haye Sainte, the second was the recapture of Plancenoit.

La Haye Sainte, standing still untaken before the very front of Wellington's line, must be captured if yet a further effort was to be attempted by Napoleon. Major Baring had held it with his small body of Germans all day long. Twice had he thrust back a general a.s.sault, and throughout more than five hours he had resisted partial and equally unsuccessful attacks. Now Ney, ordered to carry it at whatever cost, brought up against it a division, and more than a division. The French climbed upon their heaped dead, broke the doors, shot from the walls, and, at the end of the butchery, Baring with forty-two men--all that was left him out of nine companies--cut his way back through to the main line, and the farm was taken. Hougomont, on the left, round which so meaningless a struggle had raged all day long, was never wholly cleared of its defenders, but the main body of it was in flames, and with the capture of La Haye Sainte the whole front was free for a final attack at the moment which Napoleon should decide.
