A flame flickered on the walls, spread like fire catching on dry thatch, then heaved itself up into the air and down into the ditch. Another flame followed, then another, and the breach was lit like daylight as the carcasses, oil-soaked, hard-packed straw that was bound in tarred canvas, were lit and tossed into the ditch so that the defenders could see their targets. There was a cheer from the French, a triumphant, defiant cheer, and the musket balls plucked at the Forlorn Hope, revealed close to the summit of the jumbled stone slope, and the cheer was answered by the 45th and 88th as the battalions ran forward, a dark mass in the tangled maze of the ditch, and the assault began to look easy.

'Rifles! Sharpe shouted. He had eleven Riflemen left, apart from Harper and himself, of the thirty men he had led away from the horrors of the Corunna retreat three years before. They were the core of his Company, the green-jacketed specialists, whose modern Baker rifles could kill at three hundred paces and more, while the smooth-bore musket, the Brown Bess, was virtually useless at more than fifty yards. He heard the distinctive crack of the weapons, less muffled than the muskets, and saw a Frenchman fall back as he tried to throw another burning carcass down the breach slope. Sharpe wished he had more rifles. He had trained some of his redcoats to use the weapon, but he would have liked more.

He ducked down beside Lawford. The French had switched to grapeshot that left the cannon barrels like duck shot from a fowling piece. He heard the whistle of balls over his head, saw a flame stab down into the ditch towards the crowded battalions, but in the firelight he could see the red-jacketed British were nearing the mid-point of their climb. The Forlorn Hope, still almost intact, were just paces from the top, their bayonets held out, while behind them the lower half of the breach was darkened by the mass of the assaulting column.

Lawford touched Sharpe's arm. 'It's too easy!

Muskets spat at the assault, but not enough to check the attack. The men in the ditch felt victory close, easily gained, and the column moved on to the breach like a beast uncoiling from the ditch. Victory was close, just seconds away, and the growl was a cheer that rose with the column's climb.

The French had let them come. They let the Hope reach the very top of the shattered wall and then they unmasked the defence. There was a twin explosion, horrendous and ear-shattering, and flames startled across the breach. Sharpe winced. The cheer was laced with screams, spattered by the rattle of grapeshot, and he saw the French had mounted two guns, in hidden casements dug deep into the core of the walls either side of the breach, that could fire across the attack. They were not small guns, not field-guns, but massive pieces whose flames lanced clear across the full hundred feet width of the breach.

The Forlorn Hope disappeared, snatched into oblivion in a maelstrom of flame and grapeshot, and the head of the column was shattered by the gunfire that lacerated the upper half of the breach, clearing it with contemptuous ease. The growl faltered, turned into cries of alarm, and the column retreated, not from the guns, but from a new danger.

Flames appeared in the smoke-shrouded rubble, livid serpents that flickered in the stone, forked lightning that ran quicksilver down the scoured stones to touch the mines that had been hidden in the breach. The explosions tore the lower slope apart, flinging men and masonry into the air, blowing the first attack into failure. The meat-grinder of the breach had begun to turn.

The growl was still audible. The men from Connaught and Nottinghamshire were going back to the breach, over their mangled dead, past the blackened, smoking pits where the mines had been dug, and the French screamed insults at them; called them boy-lovers and weaklings, and followed the insults with more burning carcasses and lumps of timber or stone that avalanched on the slope and hurled men back into the blood-soaked base of the breach. The vast guns in their hidden, flanking casements were being reloaded, ready for their next targets, and they came, clawing their way up the blood-slick ramp till the thunder crashed again, the flames slapped at the breach, and the myriad scraps of grapeshot blasted the stones clear.

The assault had been bloodily repulsed, but there was no thought except to go forward. The foot of the ramp was crowded with the men of the two battalions who climbed again in the mindless, seething bravery of siege warfare.

Lawford clutched Sharpe's arm, leaned close to his ear. 'Those bloody guns!

'I know! They fired again, a fraction early, and it was plain that no man could climb past their fire. They were dug into the very heart of the town's thick, low wall and no British siege gun could have hoped to reach them; not unless Wellington had fired at each hidden casement for a week until the whole wall collapsed like the breach itself. In front of each gun, revealed by the burning carcasses, was a trench that defended the gunners from their enemy on the breach, and as long as the two guns were firing, across and slightly ahead of each other, there could be no victory.

The troops were climbing again, slower now, wary of the guns and trying to avoid the burning grenades that the French were tossing on to the slope. The red explosions punctured the scattered attackers. Sharpe turned to Harper. 'Are you loaded?

The huge Sergeant nodded, grinned, and held up the seven-barreled gun.

Sharpe grinned back. 'Shall we join in?

Lawford shouted at them. 'What are you doing?

Sharpe pointed at the nearest side of the breach. 'Going after the gun. Do you mind?

Lawford shrugged. 'Be careful!

There was no time to think, just to jump into the ditch and pray that their ankles would not twist or break. Sharpe fell awkwardly, slipping on the snow, but a huge hand grabbed his greatcoat, hauled him upright, and the two men ran across the floor of the ditch. The jump had been twenty feet and it seemed as if they had fallen into the bottom of a giant cauldron, an alchemist's vessel of fire, and the flames poured in from above. Carcasses rolled down, musket and cannon flame spat from above, and the fire spilt on to the living and dead flesh in the ditch and was reflected red on the underside of the low clouds that rolled southwards to Badajoz. There was only one way to live in the cauldron, and that was to go upwards, and the column was climbing again as Sharpe and Harper skirted the mass of men, and then the guns spoke, and the attack was flung back by the flame-borne grape-shot.

Sharpe had been counting the gaps between the shots and knew that the French gunners were taking about a minute to reload each giant gun. He counted the seconds in his head as the two men struggled past the mass of Irishmen to the left of the breach. They fought their way through the crush, going for the very edge of the slope, and the surge of men carried them forward so that, for an instant, Sharpe thought they would be carried on to the rubble slope itself. Then the guns fired again and the men ahead recoiled, something wet slapped Sharpe's face, and the attack was broken into small groups. He had a minute. 'Patrick!

They threw themselves into the trench beside the breach, the trench that protected the gun. It was already filled with men sheltering from the grapeshot. The French gunners, over their heads, would be sponging out and desperately ramming the huge, serge bags of powder into the vast muzzles while other men waited with the lumpy, black bags of grapeshot. Sharpe tried to forget them. He looked up the wall to the casement's lip. It was high up, far higher than a man's height, so he braced his back on the wall, cupped his hands and nodded to the Sergeant. Harper put a massive boot into Sharpe's hands, cocked the seven-barreled gun, and nodded back. Sharpe heaved and Harper pushed up, the Irishman weighed as much as a small bullock. Sharpe grimaced with the effort and then two of the Connaught Rangers, seeing their intention, joined in and pushed up on Harper's legs. The weight suddenly disappeared. Harper had grasped the casement's edge with one hand, ignoring the musket bullets that flattened themselves on the wall beside him, threw the huge gun over the edge, aimed blindly, and pulled the trigger.
