“Ten of midday?” Sharpe asked.

“When Bonaparte opened fire. It’s good to be accurate about these things.”

“Is it?”

“The Peer likes to be specific. I’m one of his family by the way.” By which the pleasant-faced young man meant he was one of the Duke’s aides. “My name is Witherspoon.”

“Sharpe. And this is my friend Mr Harper from Ireland.”

Captain Witherspoon nodded genially at Harper, then cocked an eye at the clouds. “I suspect it might well clear up. I detected a quite definite rise in the mercury this morning. I’m honoured to make your acquaintance, Sharpe! You’re with the Young Frog, are you not?“

“Yes, I am.”

“Is he good for anything at all?”

Sharpe smiled at Captain Witherspoon’s disingenuous tone. “Not that I know of.”

The cavalryman laughed. “I was at Eton with him. He wasn’t any good there either, though he had a mighty fine opinion of himself. I remember him as being eternally dirty! But he liked the girls, and had a prolific fondness for wine.”

“What’s the time now?” Sharpe asked in apparently rude disregard of Witherspoon’s gossip.

Witherspoon hauled his watch from his fob and clicked open the lid. “Four minutes after midday, save a few seconds.”

“You’d best write down that the French are advancing, then.”

“They’re doing what? Oh, my soul! So they are! Thank you, my dear fellow! Good Lord, they advance, indeed they do!” He dashed a note into his book.

French skirmishers were swarming towards Hougoumont. They came in a loose mass of men; running, firing, running again. They were mostly among the trees, which gave cover from the foot of their ridge right up to the walls of the chateau, but some had overlapped onto the open flank where newly cut hay lay in sopping rows among the stubble. The skirmishers of the red-coated Cold-stream Guards were falling back fast, evidently ordered not to make a fight of it among the trees. With the redcoats were some Dutch and German troops, the Germans armed with long-barrelled hunting rifles. Sharpe saw at least two of the blue-coated Dutch-Belgian troops running towards the enemy, presumably seeking shelter.

The Guards skirmishers scrambled back into-the farm buildings or into the walled garden and orchard that lay alongside the chateau. The French skirmishers had advanced to the very edge of the wood and were hidden from Sharpe by the loom of the chateau’s buildings. “I’m going down there,” he told Harper, pointing to the field where a handful of the French skirmishers sheltered behind the rows of wet hay.

“I’ll come with you,” Harper said obstinately.

“Take care!” Captain Witherspoon called after the two Riflemen.

Sharpe cantered his horse down the farm track, past a haystack that stood outside the chateau’s rear gates, and then into the open field to the west. The few French skirmishers who had been sheltering behind the cut hay had gone back to the wood, evidently scoured from the field by muskets fired from loopholes hacked in Hougoumont’s barns. Sharpe was only a hundred yards from the fight, but he was as safe from it as if he had been on the moon. The French had only one object, and that was to capture the buildings from where they could rake the British-held ridge behind with close-range cannon-fire. They had taken the woods, and now the mass of blue-coated infantry readied themselves for the final rush at the sprawling farm. Some of the French used axes to chop big holes in the hedge that bordered the wood. More French battalions filed into the trees until the woods were filled with enemy infantry waiting for the bugle, which would throw the attack forward.

The bugle sounded; the French cheered, and the great mass rushed at the gaps in the hedge.

The defenders opened fire.

The Guards were behind ditches and hedges, safe behind walls, or firing from the windows in the chateau’s upper floors. A blast of musketry crashed down on the French attack, and every musket fired was immediately replaced by another loaded weapon that fired and in turn was replaced at the loophole or firing step. The crackle of the muskets was incessant, drowning the cannon-fire from the ridge beyond. Smoke filled the space south of the chateau’s walls; smoke that was twitched and torn by new musket blasts that glowed red and sudden inside the acrid cloud. Somehow enough Frenchmen survived the musket volleys to reach the-chateau’s walls where they clawed to drag the British muskets clean out of the loopholes. Instead the muskets fired, hurling attackers back into the faces of the men who advanced behind.

There seemed more hope of capturing the kitchen garden that was protected by a wall only a few inches taller than a man. Some of the French held their muskets over their heads to fire blindly down across the wall’s coping. Others fired through the British loopholes, while the bravest tried to climb the wall and some even straddled it to stab down with their long bayonets.

Yet the Guards knew how to defend. For every French musket fired into a loophole a dozen British shots replied, while those brave Frenchmen who gained the wall’s top were either shot back or else pulled over to be bayoneted among the broken pea plants or in the trampled rose beds. Outside the garden the foot of the wall became treacherous with the bodies of the dead and dying French. Inside the garden files of men queued to take their turn at the loopholes, so that the musket-fire never slackened and the heavy lead balls smashed into the mass of Frenchmen who still ran forward from the trees to be baulked by the wall. Bugles and shouts urged them on.

The chateau’s orchard, beyond the garden, had no walls, but only a thick blackthorn hedge. The Guards fired through and over the hedge, but the French brought up pioneers’ axes and defended each axeman with a group of muskets, and it seemed that the Emperor’s men would have to win here by sheer weight of numbers. The axes crashed at the thick thorn trunks, ripping and shredding and tugging the obstacle away. A redcoat lunged his bayonet at an axeman, lunged too far, and was dragged screaming over the thorns to be ripped by a dozen bayonets.

Then a shell exploded above the French.

Sharpe looked up. High in the sky was a tangle of arcing smoke trails, evidence that the howitzers on the ridge were firing Britain’s secret weapon: the spherical case shell invented by Major-General Shrapnel. The shell was a five-and-a-half-inch sphere packed with musket-balls and a powder explosive that, if its fuse was cut to a precise length, would explode lethally in the air above its target. The difficulty lay in cutting the fuses which were affected by humidity as well as by the exact length of the shell’s flight, yet these fuses had been cut by a genius for the salvoes were murderously precise. Common shell burst into a few big fragments, but spherical case showered a killing rain of thin casing and musket-balls, and now caseshot after caseshot was crashing apart above the French infantry and the musket-balls and jagged iron fragments were slashing down to cut swathes of bloody flesh in the French attackers.

“That is pretty work! Ton my soul, but that’s very well done!” Captain Witherspoon had followed Sharpe and Harper to their vantage point and now applauded the skill of the gunners who were dropping the spherical case exactly in the right place; none falling short on the Guards, but all arcing onto the French attackers.

The musket-fire still hammered from the chateau’s walls. The French were faltering now, assailed from above and from their front. Some edged backwards, seeking the shelter of the trees, but the howitzers seemed to anticipate the move and the shrapnel blasts moved away from the chateau to flense the oaks in the wood of their leaves and branches. Each shell cracked apart with a sharper bang than common shell. In Spain Sharpe had noticed how the spherical case caused more wounds then deaths, but the sight of wounded men streaming back through the trees would shake the confidence of the French troops advancing in support of the first attack.
