Elsewhere the British artillery was too exposed to be defended, and the gunners again fled back to the squares. Once more the cavalry surrounded our footmen, like "heavy surf breaking on a coast beset with isolated rocks, against which the mountainous wave dashes with furious uproar, breaks, divides, and runs hissing and boiling far beyond." Yet, as before, it failed to break those stubborn blocks, and a perplexing pause occurred, varied by partial and spasmodic rushes. "Will those English never show us their backs"—exclaimed the Emperor, as he strained his eyes to catch the first sign of rout "I fear," replied Soult, "they will be cut to pieces first." For the present, it was the cavalry that gave way. Foiled by that indomitable infantry, they were again charged by British and German hussars and driven into the valley.
Once more Ney led on his riders, gathering up all his reserves. But the Duke had now brought up Adam's brigade and Duplat's King's Germans to the space behind Hougoumont; their fire took the horsemen in flank: the blasts of grape and canister were as deadly as before: one and all, the squares held firm, beating back onset after onset: and by 6 o'clock the French cavalry fell away utterly exhausted.[517]
Who is to be held responsible for these wasteful attacks, and why was not French infantry at hand to hold the ground which the cavaliers seemed to have won? Undoubtedly, Ney began the first attack somewhat too early; but Napoleon himself strengthened the second great charge by the addition of Kellermann's and Guyot's brigades, doubtless in the belief that the British, of whose tenacity he had never had direct personal proof, must give way before so mighty a mass. Moreover, time after time it seemed that the attacks were triumphant; the allied guns on the right centre, except Mercer's, were nine or ten times taken, their front squares as often enveloped; and more than once the cry of victory was raised by the Emperor's staff.
Why, then, was not the attack clinched by infantry? To understand this we must review the general situation. Hougoumont still defied the attacks of nearly the whole of Reille's corps, and the effective part of D'Erlon's corps was hotly engaged at and near La Haye Sainte. Above all, the advent of the Prussians on the French right now made itself felt. After ceaseless toil, in which the soldiers were cheered on by Blücher in person, their artillery was got across the valley of the Lasne; and at 4.30 Bülow's vanguard debouched from the wood behind Frischermont. Lobau's corps of 7,800 men, which, according to Janin, was about to support Ney, now swung round to the right to check this advance.[518] Towards 5 o'clock the Prussian cannon opened fire on the horsemen of Domont and Subervie, who soon fell back on Lobau.
Bülow pressed on with his 30,000 men, and, swinging forward his left wing, gained a footing in the village of Planchenoit, while Lobau fell back towards La Belle Alliance. This took place between 5.30 and 6 o'clock, and accounts for Napoleon's lack of attention to the great cavalry charges. To break the British squares was highly desirable; but to ward off the Prussians from his rear was an imperative necessity. He therefore ordered Duhesme with the 4,000 footmen of the Young Guard to regain Planchenoit. Gallantly they advanced at the charge, and drove their weary and half-famished opponents out into the open.
Satisfied with this advantage, the Emperor turned his thoughts to the British and bade Ney capture La Haye Sainte at all costs. Never was duty more welcome. Mistakes and failures could now be atoned by triumph or a soldier's death. Both had as yet eluded his search. Three horses had been struck to the ground under him, but, dauntless as ever, he led Donzelot's men, with engineers, against the farm. Begrimed with smoke, hoarse with shouting, he breathed the lust of battle into those half-despondent ranks; and this time he succeeded. For five hours the brave Germans had held out, beating off rush after rush, until now they had but three or four bullets apiece left. The ordinary British ammunition did not fit their rifles; and their own reserve supply could not be found at the rear. Still, even when firing ceased, bayonet-thrusts and missiles kept off the assailants for a space, even from the half-destroyed barn-door, until Frenchmen mounted the roof of the stables and burst through the chief gateway: then Baring and his brave fellows fled through the house to the garden. "No pardon to these green devils" was now the cry, and those who could not make off to the ridge were bayoneted to a man.[519]
This was a grave misfortune for the allies. French sharpshooters now lined the walls of the farm and pushed up the ridge, pressing our front very hard, so that, for a time, the space behind La Haye Sainte was practically bare of defenders. This was the news that Kennedy took to Wellington. He received it with the calm that bespoke a mighty soul; for, as Sir A. Frazer observed, however indifferent or apparently careless he might appear at the beginning of battles, as the crisis came he rose superior to all that could be imagined. Such was his demeanour now. Riding to the Brunswickers posted in reserve, he led them to the post of danger; Kennedy rallied the wrecks of Alten's division and brought up Germans from the left wing; the cavalry of Vandeleur and Vivian, moving in from the extreme left, also helped to steady the centre; and the approach of Chassé's Dutch-Belgian brigade, lately called in from Braine-la-Leud, strengthened our supports.
Had Napoleon promptly launched his Old and Middle Guard at Wellington's centre, victory might still have crowned the French eagles. But to Ney's request for more troops he returned the petulant answer: "Troops? where do you want me to get them from? Am I to make them?" At this time the Prussians were again masters of Planchenoit. Once more, then, he turned on them, and sent in two battalions, one of the Old, the other of the Middle Guard. In a single rush with the bayonet these veterans mastered the place and drove Bülow's men a quarter of a mile beyond, while Lobau regained ground further north. But the head of Pirch's corps was near at hand to strengthen Bülow; while, after long delays caused by miry lanes and an order from Blücher to make for Planchenoit, Ziethen's corps began to menace the French right at Smohain. Reiche soon opened fire with sixteen cannon, somewhat relieving the pressure on Wellington's left.[520]
Still the Emperor was full of hope. He did not know of the approach of Pirch and Ziethen. Now and again the muttering of Grouchy's guns was heard on the east, and despite that Marshal's last despatch, Napoleon still believed that he would come up and catch the Prussians. Satisfied, then, with holding off Bülow for a while, he staked all on a last effort with the Old and Middle Guard. Leaving two battalions of these in Planchenoit, and three near Rossomme as a last reserve, he led forward nine battalions formed in hollow squares. A thrill ran through the line regiments, some of whom were falling back, as they saw the bearskins move forward; and, to revive their spirits, the Emperor sent on Labédoyère with the news that Grouchy was at hand.
Thus the tension of hope long deferred, which renders Waterloo unique among battles, rose to its climax. Each side had striven furiously for eight hours in the belief that the Prussians, or Grouchy, must come; and now, at the last agony, came the assurance that final triumph was at hand. The troops of D'Erlon and Reille once more clutched at victory on the crest behind La Haye Sainte or beneath the walls of Hougoumont, while the squares of the Guard struck obliquely across the vale in the track of the great cavalry charges. On the rise south-west of La Haye Sainte, Napoleon halted one battalion and handed over to Ney the command of the remaining eight, that hailed him as they passed with enthusiastic shouts. Two aides-de-camp just then galloped up from the right to tell him of the Prussian advance, but he refused to listen to them and bent his eyes on the Guards.[521]
