Waterloo_ June 18, 1815_ The Battle for Modern Europe - Andrew Roberts [14]
When Napoleon was informed by General Drouot, Adjutant-General of the Imperial Guard, that the artillery needed firmer ground before it could be properly deployed, he made his next major error. Since he had no idea that the Prussians were back on the offensive, and were even then marching towards him from Wavre, he believed that time was on his side, rather than its being a precious but fast-diminishing commodity.
So when at the breakfast conference Jérôme Bonaparte had said that the waiter serving him the previous day had overheard Wellington saying that the Prussians would arrive in front of the Forest of Soignes, Napoleon merely scoffed at his youngest brother, dismissing the information out of hand. Shakespeare would easily have recognised the role that hubris and arrogance played in Napoleon’s downfall.
To haul a twelve-pounder cannon — so called because of the weight of shot it fired, nearly a stone of lead per round — up a slope, in mud, was no mean undertaking; and Napoleon’s Grand Battery at Waterloo constituted sixty guns and twenty howitzers. Yet the demands of Drouot and the artillery experts that the ground be allowed to dry first — which sounded only sensible to someone who had learnt his military trade as a gunner — meant that Napoleon squandered his chance for an early assault on the Anglo-Allied army before the Prussians arrived on the scene.
The late start was not entirely the Emperor’s fault. His army took far longer to assemble than was originally envisaged, coming up from their sodden sleeping areas and bivouacs sometimes miles from the battlefield. Many troops had been dispersed to forage for food and shelter in the downpour, and the mud delayed the forming up of units on the battlefield. Of course, had Napoleon had an inkling of the proximity of the Prussians, none of this would have been allowed to preclude a dawn attack.
Another effect of the heavy rainfall of the night of 17–18 June that worked against Napoleon was the way that it softened the ground, to the extent that cannonballs tended to plough into the mud, rather than bounce along hardened ground. A cannonball fired at sun-baked ground might bounce as many as five or six times, leaving death and carnage in its wake, while one that merely buried itself after its initial impact had only a fraction of that lethal capacity. Tests undertaken by the Royal Artillery in 2003 proved how diminished were Napoleon’s batteries’ effectiveness by the downpour the night before the battle.
While Napoleon could hardly have ordained good weather, he did make serious blunders of his own for which he must take ultimate blame. Instead of ordering Grouchy to return to the scene as soon as possible, at 10 a.m. on 17 June Napoleon had sent him orders to march on Wavre and engage the Prussians, orders which could only have the effect of forcing them closer towards junction with Wellington. Several of Napoleon’s written orders during the campaign were unclear or contradictory — his handwriting was, moreover, akin to the meanderings of an intoxicated spider — but these instructions were particularly strategically inept.
At only three miles wide by one and a half deep, Waterloo was a very small battlefield by Napoleonic standards, especially for a total of over 180,000 men to fight in. Napoleon’s tactical options were therefore severely limited, since Wellington had effectively closed down large areas of the battlefield to him. The huge flanking movements that Napoleon often favoured were effectively blocked off, to the east by the well-defended farm buildings of the hamlets of Papelotte, La Haye and Frischermont and to the west by the village of Braine l’Alleud. Napoleon therefore decided upon a frontal assault with a couple of mild diversions, which was hardly an inspired tactic, but was perhaps all that was open to him given the terrain.
Since the horrifically expensive battle of Borodino outside Moscow in 1812 Napoleon had inured himself to the terrible losses inherent in frontal assaults, and the French
