In Brussels the gun-fire sounded like very distant thunder, sometimes fading to a barely perceptible rumble, but at other times swollen by a vagary of wind so that the distinct percussive shocks of each gun’s firing could be distinguished. Lucille, troubled by the sound, walked Nosey to the southern ramparts where she joined the crowd who listened to the far-off noise and speculated what it might mean. The majority hoped it signified Napoleon by nightfall, a torchlight parade and dancing. The Empire would be restored and safe, for surely the Austrians and Russians would not dare attack France if Britain and Prussia had been defeated?

The first news from the battlefield gave substance to those Imperial hopes. Belgian cavalrymen, their horses sweating and exhausted, brought tales of a shattering French victory. It had been more of a massacre than a battle, the horsemen said. British corpses were strewn across the landscape, Wellington had been killed, and the troops of the Emperor were even now advancing on Brussels with drums beating and Eagles flying.

Lucille noted that the guns were still firing, which seemed to cast doubt on the Belgian claims of victory, though some of the hundreds of English civilians still in Brussels were more ready to give the news credence. They ordered their servants to load the travelling boxes and trunks onto the coaches that had been standing ready since dawn. The coaches were whipped out of the city on the Ghent road; their passengers praying that they would reach the Channel ports before the Emperor’s scavenging and victorious horsemen cut the roads. Others of the English, more cautious, waited for official news.

Lucille, unwilling to flee with her child into an unknown future, walked beside one of the first carts of wounded that reached the city. A British infantry sergeant, his face bandaged and one arm crudely splinted, told her that the battle had not been lost when he left Quatre Bras. “It was hard work, ma’am, but it v/eren’t lost. And as long as Nosey’s alive it won’t be lost.”

Lucille went back to her child. She closed the window in the hope that the glass would obscure the sound of the cannons, but the noise drummed on, insistent and threatening. To the west the thunderheads were heaping into a sombre bank that cast an unnaturally dark shadow across the city.

Fiye streets away from Lucille, in the expensive suite of rooms that had been so thoroughly fumigated, Jane Sharpe vomited.

Afterwards, gasping for breath from the stomach-griping heaves, she went to the window, rested her forehead on the cool glass, and stared at the great ridge of cloud that blackened the western sky. Beneath her, in the hotel yard, a groom whistled as he carried two pails of water from the pump. A flock of pigeons circled, then fluttered down to the stable roof. Jane was aware of none of it, not even of the harsh percussive grumble of gun-fire. She closed her eyes, took a deep, tentative breath, then groaned.

She was pregnant.

She had suspected as much before she and Lord John had left England, but now she was certain. Her breasts were sore and her stomach sour. She ticked the months down on her fingers, reckoning that she would have a January child; a winter’s bastard. She swore softly.

She stepped away from the window and crossed to the dressing-table where last night’s candles still stood in their puddles of cold wax. She still felt sick. Her skin was prickly with sweat. She hated the thought of being pregnant, of being lumpish and awkward and gross. She rang for her maid, then sat heavily to stare into the looking-glass.

„Has Harris returned?“ Jane asked the maid.

“Yes, ma’am.”

“Tell him I shall want him to take a message to his lordship.”

“Yes, ma’am.”

Jane waved the maid out of the room, then drew a heavy sheet of creamy writing paper towards her. She dipped a quill in ink, sat for a moment in thought, then began to write. The guns fired on.

More troops were arriving at Quatre Bras; troops who had marched till their blistered feet were agony, but who now had to plunge straight into the humid, smoke’thickened air where, unit by unit, the Duke was building the force that would counter-attack the French and drive them back to Frasnes. More and more British guns crashed and jangled off the road and onto the crushed rye stalks. Fires were burning in the crops behind the French skirmishers as British howitzer shells exploded. The battle was not won yet, but the Duke was beginning to feel like a man who had escaped defeat. He knew his Guards Division was close, and there was even a rumour that the British cavalry might reach the crossroads before dark.

A small west wind was stirring the thick smoke. The British skirmishers, reinforced by newly arrived battalions of light infantry, were beginning to blunt the fire of the Voltigeurs. The French artillery was still taking its grievous toll of the infantry by the crossroads, but now the Duke could replace the men who fell. If Blücher held off the Emperor, and if Marshal Ney was thrown back from Quatre Bras, then in the morning the Prussian and British armies would combine and Napoleon would have lost.

The Duke opened his watch lid. It was half-past five of a summer’s evening. The battlefield was darkening, shadowed by the huge western clouds and shrouded by its pall of smoke, but plenty of daylight remained for the Duke’s counter-stroke. “Any news of the Guards?” he asked an aide.

It seemed that the Guards were being apprehended by the Prince of Orange who, as company after company of the elite troops arrived, was sending them north through the great wood to reinforce Saxe-Weimar’s men. The Duke, muttering that the Prince was a bloody little boy who should be sent back to his nursery, ordered that the Guards were not to be so dispersed in penny packets, but were to be held ready for his orders.

“Your Grace!” an aide called in warning. “Enemy cavalry!”

The Duke turned to stare southwards. Through the smoke he saw a mass of French cavalry spurring up from dead ground and heading slantwise across the field. They were a half-mile away, and well spread out in four long lines. Their loose formation made them a poor target for artillery, but the British gunners loaded with common shell and did their best. The explosions knocked down a few men and horses, but the vast mass of French cavalry trotted safely through the bursting patches of flame and smoke.

The Duke extended his telescope. “Where are they going?” He was puzzled. Surely his opponent had learned by now that cavalry could achieve nothing against the stalwart squares which had been reinforced with the newly arrived guns?

“Perhaps they’re testing Halkett’s men?” an aide suggested.

“Then they’re committing suicide!” The Duke had his glass trained on the front line of cavalry that was composed of the heavy Cuirassiers in their steel armour. Behind the Cuirassiers were the light horsemen with their lances and sabres. “They must be insane!” the Duke opined. “Halkett’s in square, isn’t he?”

Almost in unison the telescopes of the Duke’s staff officers swept to the right of the field, racing past the patches of smoke to focus on the four battalions of Halkett’s brigade which stood in front of the wood. The brigade was obscured by cannon smoke, but there were enough rifts in the dirty screen to show that something had gone terribly wrong. “Oh, Christ.” The voice spoke helplessly from the Duke’s entourage. There was a moment’s silence, and then again. “Oh, Christ.” “

“Sir?” Rebecque handed the Prince his telescope and pointed towards Gemioncourt farm. “There, sir.”

The Prince trained the heavy glass. Thousands of horsemen had appeared from the dead ground and now, in four long lines, swept either side of the farm. Dust spurted from the road as the horsemen crashed across. The enemy cavalry was trotting, but, even as the Prince watched, he saw them spur into a canter. The Cuirassiers had their heavy straight swords drawn. Long horsehair plumes tossed and waved from the steel brightness of their helmets. A Cuirassier was hit by a British roundshot and the Prince involuntarily jumped as, magnified in his lens, the steel clad horseman seemed to explode in blood and metal. The Lancers and Hussars, cantering behind, divided to pass the butcher’s mess left on the ground.
