Battle of Waterloo - Armies

Armies

Three armies were involved in the battle: Napoleon's Armée du Nord; a multinational army under Wellington; and a Prussian army under Blücher. The French army of around 69,000 consisted of 48,000 infantry, 14,000 cavalry, and 7,000 artillery with 250 guns. Napoleon had used conscription to fill the ranks of the French army throughout his rule, but he did not conscript men for the 1815 campaign. All his troops were veterans of at least one campaign who had returned more or less voluntarily to the colours. The cavalry in particular was both numerous and formidable, and included fourteen regiments of armoured heavy cavalry and seven of highly versatile lancers. Neither Coalition army had any armoured troops at all, and Wellington had only a handful of lancers.

Wellington claimed he had "an infamous army, very weak and ill-equipped, and a very inexperienced Staff". His troops consisted of 67,000 men: 50,000 infantry, 11,000 cavalry, and 6,000 artillery with 150 guns. Of these, 25,000 were British, with another 6,000 from the King's German Legion. All of the British Army troops were regular soldiers but only 7,000 of them were Peninsular War veterans. In addition, there were 17,000 Dutch and Belgian troops, 11,000 from Hanover, 6,000 from Brunswick, and 3,000 from Nassau.

Many of the troops in the Coalition armies were inexperienced. The Dutch army had been re-established in 1815, following the earlier defeat of Napoleon. With the exception of the British and some from Hanover and Brunswick who had fought with the British army in Spain, many of the professional soldiers in the Coalition armies had spent some of their time in the French army or in armies allied to the Napoleonic regime. Wellington was also acutely short of heavy cavalry, having only seven British and three Dutch regiments. The Duke of York imposed many of his staff officers on Wellington, including his second-in-command, the Earl of Uxbridge. Uxbridge commanded the cavalry and had carte blanche from Wellington to commit these forces at his discretion. Wellington stationed a further 17,000 troops at Halle, 8 miles (13 km) away to the west; they were not recalled to participate in the battle but were to serve as a fallback position should the battle be lost. They were mostly composed of Dutch troops under William, Prince of Orange's younger brother Prince Frederik of the Netherlands.

The Prussian army was in the throes of reorganisation. In 1815, the former Reserve regiments, Legions, and Freikorps volunteer formations from the wars of 1813–1814 were in the process of being absorbed into the line, along with many Landwehr (militia) regiments. The Landwehr were mostly untrained and unequipped when they arrived in Belgium. The Prussian cavalry were in a similar state. Its artillery was also reorganising and did not give its best performance – guns and equipment continued to arrive during and after the battle. Off-setting these handicaps, however, the Prussian Army did have excellent and professional leadership in its General Staff organisation. These officers came from four schools developed for this purpose and thus worked to a common standard of training. This system was in marked contrast to the conflicting, vague orders issued by the French army. This staff system ensured that before Ligny, three-quarters of the Prussian army concentrated for battle at 24 hours notice. After Ligny, the Prussian army, although defeated, was able to realign its supply train, reorganise itself, and intervene decisively on the Waterloo battlefield within 48 hours. Two and a half Prussian army corps, or 48,000 men, were engaged at Waterloo – two brigades under Friedrich von Bülow, commander of IV Corps, attacked Lobau at 16:30, while Zieten's I Corps and parts of Georg von Pirch's II Corps engaged at about 18:00.
