While Chasse was engaging the 3rd Grenadiers, the 4th Grenadiers of the Guard, reduced to a single battalion by its losses at Ligny two days earlier, attacked the right flank of Sir Colin Halkett’s brigade, supported by two guns of the Guard horse artillery reserve. The combined musket and grapeshot fire caused the British 33rd and 69th Regiments to waver, but any thought of retreat was banished by Halkett himself waving the flag of the 33rd above his head. Both regiments stood firm and the 4th Grenadiers were eventually also repulsed. Wellington’s centre had withstood the attack of the first Guard echelon, the grenadiers. Now was the time for the second and third echelons, made up of chasseurs.
Marching in two columns through and over the human and horseflesh debris of Ney’s futile cavalry attacks earlier in the day — ‘The ground was completely covered with those brave men, who lay in various positions, mutilated in every conceivable way’5 — the three battalions of chasseurs also almost reached the crest of Wellington’s (today non-existent) ridge. They had been subjected to roundshot fire from the horse artillery troop formerly commanded by Major Norman Ramsay (who had been killed earlier in the day) from the moment they had formed up thousands of yards back near La Belle Alliance, but by the time they reached their destination their ammunition was getting scarce. Certainly the roared war-cries of the chasseurs could be easily heard over the boom of the cannon. Yet their formation was effectively split by the nature of the ridge, which is very apparent if one stands to the south of La Haye Sainte and advances north-north-west; visitors to the battlefield are encouraged to do this in order to appreciate the difficulties the Guard had in trying to stay together in this great assault.
As the 1st and 3rd Chasseurs a Pied of the Middle Guard mounted the crest in their attempt to reach the Ohain road — in some places they were only about twenty yards off — they were suddenly faced by the apparition of the British ist Foot Guards rising up from out of the corn where Wellington had hidden them. ‘Up Guards, ready!’is one of the many versions of the command that the Duke gave them as they presented their muskets and volleyed at almost point-blank range. Lieutenant Captain Harry Weyland Powell of the 1st Regiment of Foot Guards described the scene:
Whether it was from the sudden and unexpected appearance of a Corps so near them, which must have seemed as starting out of the ground, or the tremendously heavy fire we threw into them,
Meanwhile, field brigades such as that of Captain Napier fired grapeshot at ranges of 200 yards and less, and the troops of the 3rd Chasseurs who still wanted to close with the enemy found that they had to climb over the corpses of their fallen comrades in order to do so. The assault petered out. Superb inter-service coordination between the British infantry and artillery had been the key to the repulse of the 3rd Chasseurs.
After ten minutes or so of further carnage, Wellington sensed the correct moment to order the Foot Guards to fix their bayonets and charge, whereupon the 3rd Chasseurs were chased off the slopes and back to Hougoumont and beyond. Ensign Gronow took part in this engagement, recalling how:
We rushed on with fixed bayonets and that hearty ‘hurrah’ peculiar to British soldiers. It appeared that our men, deliberately and with calculation, singled out their victims, for as they came upon the Imperial Guard our line broke, and the fighting became irregular. The impetuosity of our men seemed almost to paralyse their enemies: I witnessed several of the Imperial Guard who were run through the body apparently without any resistance on their parts. I observed a big Welshman of the name of Hughes, who was six feet seven inches in height, run through with his bayonet and knock down with the butt-end of his firelock, I should think a dozen at least of his opponents.7
So many British troops followed them down that Napier’s battery was forced to stop firing altogether. Soon they had to break off their pursuit and turn back, however, because the last battalion of the Middle Guard, the 4th Chasseurs, could now be seen advancing towards the battered but still unbroken Anglo-Allied line. This truly was Napoleon’s last throw.
Facing the veterans of the Middle Guard were a hodgepodge of Anglo-Allied units. Some — like Major-General Frederick Adam’s brigade on the left flank of the enemy — were fresh, although others — such as Halkett’s brigade and the Foot Guards — were badly depleted. To complete the Middle Guard’s sense of utter isolation, the 3rd Hanoverian brigade actually debouched from Hougoumont and started to fire into their rear. It was Colonel Sir John Colborne who dealt the Middle Guard its final
Wellington once again sensed the ideal moment. He snapped his telescope shut, rode to the crest of the ridge, took off his hat and waved it to indicate a general advance across the entire battlefront to mop up any further resistance. The exact words he used at that moment are disputed, but are often quoted as: ‘Go forward, boys, and secure your victory.’
The cavalry brigades of Vivian and Vandeleur which Wellington had hitherto used sparingly — Vandeleur to extricate the Union Brigade, for example — were also then finally unleashed to break through any places where the French might attempt to stand and resist. Sir Augustus Frazer recalled two days later what it had been like fighting in the dwindling twilight:
I have seen nothing like that moment, the sky literally darkened with smoke, the sun just going down, and which till then had not for some hours broken through the gloom of a dull day, the indescribable shouts of thousands, where it was impossible to distinguish between friend and foe. Every man’s arm seemed to be raised against that of every other. Suddenly, after the mingled mass had ebbed and flowed, the enemy began to yield, and cheerings and English huzzas announced that the day must be ours.8
It was at around 8 p.m. that the cry went up through the French ranks, ‘
The Emperor bravely attempted to rescue the situation at La Haye Sainte by ordering the three Guards units still under his control — the second battalions of the 1st Chasseurs, 2nd Chasseurs and 2nd Grenadiers, under Generals Cambronne, Christiani and Roguet — to form three squares a hundred yards from the farm house, with their right almost reaching the Charleroi road. These initially withstood Vivian’s hussars, but then had to contend with both British infantry musketry and the horrific grapeshot fire of both Brevet-Major Whinyates’ and Lieutenant- Colonel Gardiner’s horse artillery troops and a field brigade under Brevet-Major Rogers, all firing at only about sixty yards’ range.
Almost impregnable to cavalry, squares are nonetheless highly vulnerable to infantry and artillery due to their highly compact nature and the paucity of muskets that can be brought to bear on any one spot, and so the carnage was terrific. After dreadful punishment, the Guard were ordered to fall back to La Belle Alliance by the Emperor, who rode off with some mounted chasseurs to try to find another position from which to rally his stricken forces, deciding upon Genappe.
It was during the Guards’ retreat that General Cambronne was asked whether he would surrender, to which he reputedly merely answered:
Lobau’s troops managed to protect the fleeing Armee du Nord as it swarmed back down the Charleroi road, whence it had come in such high expectations the previous day. The track itself was torn up by the ceaseless pounding of Prussian roundshot, fired from the by now re-recaptured village of Plancenoit (where General Duhesme was killed). Meanwhile the Prussian cavalry gave murderous chase, taking every advantage to revenge themselves on the men who had devastated their Fatherland nine years before during the Jena campaign.
Frenchmen were being lanced in the back by Prussian cavalry for as long as there was still daylight enough for the uhlans to carry out their long-awaited work of retribution. Their methodical vengeance helped turn a devastating and decisive defeat for France into an utter rout. Sergeant-Major Cotton of the 7th Hussars recorded: ‘That the French in their flight from Waterloo were unnecessarily butchered during many hours by the exasperated Prussians, is a fact, which I can more easily explain than justify.’9
