Battle

The Battle of Waterloo commenced with a diversionary attack on Hougoumont by a division of French soldiers. After a barrage of 80 cannons the first French infantry attack was commenced by Comte D'Erlon's I Corps. D'Erlon's troops advanced through the Allied centre, resulting in Allied troops in front of the ridge, retreating in disorder through the main position. D'Erlon's corps stormed the most fortified Allied position, La Haye Sainte, but failed to take it. An Allied division under Thomas Picton met the remainder of D'Erlon's corps head to head, engaging them in an infantry duel in which Picton fell. During this struggle Lord Uxbridge launched two of his cavalry brigades on the enemy, catching the French infantry off guard, driving them to the bottom of the slope, and capturing two French Imperial Eagles. The charge, however, over-reached itself, and the British cavalry, crushed by fresh French horsemen hurled on them by Napoleon, were driven suffering tremendous losses.

A little before 16:00, Marshal Ney noted an apparent exodus from Wellington's centre. He mistook the movement of casualties to the rear for the beginnings of a retreat, and sought to exploit it. Ney at this time had few infantry reserves left, as most of the infantry been committed either to the futile Hougoumont attack or to the defence of the French right. Ney therefore tried to break Wellington's centre with a cavalry charge alone.

At about 16:30, the first Prussian corps arrived. Commanded by Freiherr von Bülow, IV Corps arrived as the French cavalry attack was in full spate. Bülow sent the 15th Brigade to link up with Wellington's left flank in the Frichermont-La Haie area while the brigade's horse artillery battery and additional brigade artillery deployed to its left in support. Napoleon sent Lobau's corps to intercept the rest of Bülow's IV Corps proceeding to Plancenoit. The 15th Brigade sent Lobau's corps into retreat to the Plancenoit area. Von Hiller's 16th Brigade also pushed forward with six battalions against Plancenoit. Napoleon had dispatched all eight battalions of the Young Guard to reinforce Lobau, who was now seriously pressed by the enemy. Napoleon's Young Guard counter-attacked and, after very hard fighting, secured Plancenoit, but were themselves counter-attacked and driven out. Napoleon then resorted to sending two battalions of the Middle/Old Guard into Plancenoit and after ferocious fighting they recaptured the village.

The French cavalry attacked the British squares many times, each at heavy cost to the French but with few British casualties. Ney himself was displaced from his horse four times. Eventually it became obvious, even to Ney, that cavalry alone were achieving little. Belatedly, he organised a combined-arms attack, using Bachelu's division and Tissot's regiment of Foy's division from Reille's II Corps plus those French cavalry that remained in a fit state to fight. This assault was directed along much the same route as the previous heavy cavalry attacks.

Meanwhile at approximately the same time as Ney's combined-arms assault on the centre-right of Wellington's line, Napoleon ordered Ney to capture La Haye Sainte at whatever the cost. Ney accomplished this with what was left of D'Erlon's corps soon after 18:00. Ney then moved horse artillery up towards Wellington's centre and began to destroy the infantry squares at short-range with canister. This all but destroyed the 27th (Inniskilling) Regiment, and the 30th and 73rd Regiments suffered such heavy losses that they had to combine to form a viable square. Wellington's centre was now on the verge of collapse and wide open to an attack from the French, luckily for Wellington, Pirch I's and Zieten's corps of the Prussian Army were now at hand. Zieten's corps permitted the two fresh cavalry brigades of Vivian and Vandeleur on Wellington's extreme left to be moved and posted behind the depleted centre. Pirch I then preceded to support Billow, together they regained possession of Plancenoit, and once more the Charleroi road was swept by Prussian round shot. The value of this reinforcement at this particular moment can hardly be overestimated.

The French army now fiercely attacked the Coalition all along the line with the culminating point being reached when Napoleon sent forward the Imperial Guard at 19:30. It was mounted by five battalions of the Middle Guard, and not by the Grenadiers or Chasseurs of the Old Guard. Marching through a hail of canister and skirmisher fire and severely outnumbered, the 3,000 or so Middle Guardsmen advanced to the west of La Haye Sainte and preceded to separate into three distinct attack forces. One, consisting of two battalions of Grenadiers, defeated the Coalition's first line and marched on. Chassé's relatively fresh Dutch division was sent against them and Allied artillery fired into the victorious Grenadiers' flank. This still could not stop the Guard's advance, so Chassé ordered his first brigade to charge the outnumbered French, who faltered and broke.

Further to the west, 1,500 British Foot Guards under Maitland were lying down to protect themselves from the French artillery. As two battalions of Chasseurs approached, the second prong of the Imperial Guard's attack, Maitland's guardsmen rose and devastated them with point-blank volleys. The Chasseurs deployed to counterattack, but began to waver. A bayonet charge by the Foot Guards then broke them. The third prong, a fresh Chasseur battalion, now came up in support. The British guardsmen retreated with these Chasseurs in pursuit, but the latter were halted as the 52nd Light Infantry wheeled in line onto their flank and poured a devastating fire into them and then charged. Under this onslaught they too broke.

The last of the Guard retreated headlong. A ripple of panic passed through the French lines as the astounding news spread: "La Garde recule. Sauve qui peut!" ("The Guard retreats. Save yourself if you can!"). Wellington then stood up in Copenhagen's stirrups, and waved his hat in the air to signal an advance of the Allied line just as the Prussians were overrunning the French positions to the east. What remained of the French army then abandoned the field in disorder. Wellington and Blücher met at the inn of La Belle Alliance, on the north-south road which bisected the battlefield, and it was agreed that the Prussians should pursue the retreating French army back to France. The Treaty of Paris was signed on 20 November 1815.
