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 assault 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Under the battering of that discharge the front of Wellington’s command was partially withdrawn behind the cover of the ridge.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 mass 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 horsemen 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, passed in its entirety through the infantry, and began to advance at the trot down the valley for the assault upon the opposite slope.
I repeat, it is not certain whether Ney called upon all this mass 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 passed 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 mass of horsemen 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 cuirassiers, already shredded and lessened by grape at fifty yards and musket fire at ten. This countercharge of Uxbridge’s cleared the plateau. The French horsemen 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 horsemen round about them struck once more.
