The French kept searching for an opportunity. Whenever a battalion was marching in a column of companies and so looked ripe for attack a sudden surge of horses would flow across the field and the trumpets would rally yet more horse to join the thunderous charge, but then the redcoats' column would break, wheel and march into square with the same precision as if they were drilling on the parade ground of their home barracks. The troops would mark time for an instant as the square was achieved, then the outer rank would kneel, the whole formation would bristle with bayonets and the horsemen would sheer away in impotent rage. A few impetuous Frenchmen would always try to draw blood and gallop too close to the square only to be blasted from their saddles, or maybe a British galloper gun would bloody a whole troop of dragoons or cuirassiers with a blast of canister, but then the cavalry would gallop out of range and the horses would be rested while the square trudged back into column and marched stoically on. The horsemen would watch them go until another flurry of trumpets summoned the whole flux of mounted men to chase yet another opportunity far across the field and once again a battalion would contract into square and once again the horsemen would wheel away with unblooded blades.

And always, everywhere, ahead and behind and in between the slowly withdrawing battalions, groups of greenjackets sniped and harried and killed. French gunners became reluctant to advance while the more sober horsemen took care to avoid the small nests of riflemen that stung so viciously. The French had no rifles because the Emperor despised the weapon as being too slow for battle use, but today the rifles were making the Emperor's soldiers curse.

The Emperor's soldiers were also dying. The calm redcoat battalions were leaving scarcely any bodies behind, but the cavalry was being flayed by rifle and cannon fire. Unhorsed cavalrymen limped southwards carrying saddles, bridles and weapons. Some riderless horses stayed with their regiments, forming in the ranks whenever a squadron regrouped and charging along with the other horses when the trumpets threw the squadron into the attack. Far behind the milling cavalry the French infantry divisions hurried to join the battle, but the Light Division was outmarching the advancing French infantry. When a battalion did form column to continue the retreat it would go at the rifle speed of a hundred and eight paces to the minute—faster than any other infantry in the world. The French marching pace was shorter than the British and the speed of their march much slower than that of the specially trained troops of Craufurd's Light Division and so, despite the need to stop and form square and see off the cavalry, Craufurd's men were still outpacing the pursuing infantry while far to the north of the Light Division the main British line was being remade so that Wellington's defence now followed the edge of the plateau to make a right angle with Fuentes de Onoro at its corner. All that was needed now was for the Light Division to come safely home and the army would be complete again, ensconced behind slopes and daring the French to attack.

Sharpe took his men back another quarter-mile to a patch of rocks where his riflemen could find cover. A pair of British guns was working close to the rocks, blasting roundshot and shell at a newly placed French battery beside the wood Sharpe had just abandoned. The flow of horse began to thicken in this part of the field as the cavalry sought out a vulnerable battalion. Two regiments, one of redcoats and the other Portuguese, were retreating past the battery and the sweating horsemen stalked the two columns. Eventually the press of horse became so thick that the columns marched into squares. "Buggers are everywhere," Harper said, firing his rifle at a chasseur officer. The two British guns had switched their aim to fire canister at the cavalry in an attempt to drive them away from the two infantry squares. The guns crashed back on their trails to jar the wheels up in the air. The gunners swabbed out the barrel, rammed down a new charge and canister, pricked the powder bag through the touch-hole, then ducked aside after putting the smoking linstock to the powder fuse. The guns cracked deafeningly, smoke punched sixty feet out from the muzzles and the grass lay momentarily flat as the blast whipped overhead. A horse screamed as the musket balls spread out and thumped home.

A surge and eddy in the mass of horse presaged another move, but instead of riding back across the fields to harry a marching column the cavalry suddenly turned on the two guns. Blood dripped from horses' flanks as riders spurred frantically towards the desperate gunners who now picked up their guns' trails, turned the weapons and dropped the trail-hooks over the limbers' pintles. The team horses were run into place, the harnesses attached and the gunners scrambled up onto the guns or horses, but the French cavalry had timed their charge well and the gunners were still whipping their tired animals into motion as the leading cuirassiers swept down on the battery.

A charge of British light dragoons saved the guns. The blue-coated horsemen slashed in from the north, sabres cutting down at plumed helmets and parrying swords. More British cavalry arrived to flank the guns that were now galloping frantically northwards. The heavy cannons bounced over the rough ground, the gunners clung to the limbers' handles, the whips cracked, and all about the galloping horses and blurring wheels the cavalry hacked at each other in a running fight. A British dragoon reeled out of the fight with a face turned into a mask of blood while a cuirassier fell from his saddle to be mangled by the hooves of the gun teams then crushed by the iron-rimmed wheels of limber and cannon. Then a rippling crash of musketry announced that the rolling chaos of guns, horses, swordsmen and lancers had come into range of the Portuguese square's face and the cheated French cavalry swerved away as the two guns galloped on to safety. A cheer for the gunners' escape went up from the two allied squares, then the guns slewed about in an eruption of grass and dust to open fire again on their erstwhile pursuers.

Sharpe's men had slipped away from the rocks to join another battalion of redcoats. They marched among the companies for a few minutes, then broke off to take position in a tangle of thorns and boulders. A small group of chasseurs in green coats, black silver-looped shakoes and with carbines slung on hooks on their white crossbelts trotted close by. The French had not noticed the small group of riflemen crouched among the thorns. They were continually taking off their shakoes and wiping sweat from their faces with their frayed red cuffs. Their horses were white with sweat. One had a leg matted with blood, but it was somehow keeping up with its companions. The officer stopped his troop and one of the men unclipped his carbine, cocked the weapon and aimed at a British gun that was unlimbering to the east. Hagman put a rifle bullet into the man's head before he could pull the trigger and suddenly the chasseurs were cursing and trying to spur their horses out of rifle range. Sharpe fired, his rifle's report lost in the crackle of sound as his men sent a volley after the enemy troop. A half-dozen of the chasseurs galloped out of range, but they left as many bodies behind. "Permission to rake the bastards over, sir?" Cooper asked.

"Go on, but equal shares," Sharpe said, meaning that whatever plunder was found had to be shared among the whole squad.

Cooper and Harris ran out to filch the bodies while Harper and Finn carried bundles of empty water bottles to a nearby stream. They filled the bottles while Cooper and Harris slit the seams of the dead men's green coats, cut open the pockets of their white waistcoats, searched inside the shako linings and tugged off the short, white-tasselled boots. The two riflemen came back with a French shako half filled with a motley collection of French, Portuguese and Spanish coins. "Poor as church mice," Harris complained while he split the coins into piles. "You having a share, sir?"
