“Oh, Christ!” Murray had turned to look up the road along which the four companies must retreat. “Rear rank! About turn! Major Dunnett! They’re crapauds!”

God alone knew how, but a new enemy had appeared behind. There was no time to wonder where they had come from, only to turn and face the three fresh squadrons of Dragoons. The French cavalry rode with open cloaks which revealed their pink-faced green coats. They carried drawn swords. They were led, curiously, by a chasseur; an officer in the red coat, scarlet pelisse and black fur hat of the Emperor’s Imperial Guard. Alongside him, mounted on a big roan, was an equally strange figure; a man dressed in a black riding coat and boots that were gleaming white.

Dunnett gaped at the new enemy. Riflemen frantically reloaded empty weapons. The Quartermaster knelt, braced his rifle by looping its sling about his left elbow, and fired at the chasseur.

He missed. Rifleman Harper jeered.

A trumpet sounded from the enemy. There was death in its shrill note.

The chasseur’s sabre was raised. Beside him the man in the civilian coat drew a long slim sword. The cavalry broke into the trot and the new Lieutenant could hear the hooves on the frozen ground. The Regiment of Dragoons still rode in squadrons that could be distinguished by the colour of their horses. The first squadron was on black horses, the second on bays, and the third on chestnuts; it was an arrangement common in peacetime, but rare in battle that swiftly diluted the pattern with remounts. The trumpeters were on greys, as were the three men who carried the guidons on their long staffs. The small flags were bright against the low clouds. The Dragoons’ long swords were even brighter, like blades of pale ice.

Major Dunnett realized his Riflemen were in danger of annihilation. “Rally square! Rally! Rally!”

The greenjackets contracted into the rally square; a clumsy formation whereby men crowded together for protection against cavalry. Any man who found himself in the front rank knelt and jammed his rifle butt into the turf so that his sword-bayonet’s blade could be held rigid. Others reloaded their rifles, skinning their frozen knuckles on the sword-bayonets’ long blades as they rammed the charges home. Rifleman Cooper and his mule sheltered in the middle of the square.

The chestnut squadron wheeled from the rear of the French charge, drew carbines, and dismounted. The other two squadrons spurred into the canter. They were still a hundred paces away and would not rowel their horses to the gallop till they were very close to their target.

“Fire!” Dunnett shouted.

Those Riflemen who had reloaded fired.

A dozen saddles were emptied. The Riflemen jostled each other, shaking themselves into ranks so that the rally square became a real square from which every rifle could fire. There were three ranks of them now, each plumed with bayonets.

“Fire!” More rifles spat, more cavalry fell, then the chasseur officer, instead of pressing the charge home, wheeled his horse away and the two squadrons sheered off to unmask the dismounted men who now opened fire with their carbines. The first Dragoons, the company which had waited by the bridge, closed on the square’s eastern face.

The rally square made a perfect target for the dismounted

Dragoons. If the Riflemen shook themselves into line to sweep the makeshift infantry away, then the mounted cavalry would spur their horses back into motion and the greenjackets would become mincemeat. The chasseur Colonel, the Lieutenant thought, was a clever bastard; a clever French bastard who would kill some good Riflemen this day.

Those Riflemen began to fall. The centre of the square soon became a charnel house of wounded men, of blood, screams and hopeless prayer. The rain was stinging harder, wetting the rifle pans, but enough black powder fired to spit bullets at the enemy who, crouched in the grass, made small and elusive targets.

The two mounted squadrons had wheeled away to the west, and now reformed. They would charge along the line of the road, and the frozen steel of their heavy straight swords would burn like fire when it cut home. Except, so long as the Riflemen stayed together, and so long as their unbroken ranks bristled with the pale blades, the horsemen could not hurt them. But the enemy carbines were taking a fearful toll. And when enough Riflemen had fallen the cavalry charge would split the weakened square with the ease of a sword shattering a rotten apple.

Dunnett knew it, and he looked for salvation. He saw it in the low cloud which misted the hillside just two hundred yards to the north. If the greenjackets could climb into the obscuring shroud of those clouds, they would be safe. He hesitated over the decision. A Sergeant fell back into the square, killed clean by a ball through his brain. A Rifleman screamed as a bullet struck his lower belly. Another, shot in the foot, checked his sob of pain as he methodically reloaded his weapon.

Dunnett glanced up the hill at the cloud’s refuge. He stroked his small bristly moustache that was beaded with rain, then made his decision. “Uphill! Uphill! Keep ranks!”

The square inched uphill. The wounded screamed as they were carried. French bullets still thumped home and the greenjacket formation became ragged as men stopped to return the fire or help the casualties. Their progress was desperately slow, too slow for Major Dunnett’s frayed nerves. “Break and run! Break and run!”

“No!” The new Lieutenant shouted the countermand, but he was ignored. Dunnett’s order was given, and now it was a race. If the greenjackets could reach cover before the cavalry could reach them then they would live, but if the chasseur officer had judged his distance right, then he would win.

The red-coated chasseur had judged very well indeed.

The greenjackets ran, but over the sound of their hoarse breath and the pounding of their boots came the swelling thunder of the hooves.

A man turned and saw the bared teeth of a horse. He heard a sword hissing above the sound of the trumpet. The Rifleman screamed.

Then came chaos and slaughter.

The horsemen split the greenjackets apart then wheeled to the killing. The great swords chopped and speared. The new Lieutenant had a glimpse of a man with pigtails swinging beneath his helmet’s rim. He twisted aside and felt the wind of the Dragoon’s sword on his face. Another horseman rode at him, but he swung his rifle by its muzzle to crack the horse over the mouth. The horse screamed, reared, and the Lieutenant ran on. He was shouting for men to close on him, but the greenjackets were scattered and running for their lives. The Battalion’s mule bolted eastwards and Cooper, stubbornly trying to save his belongings which were strapped to the beast’s panniers, was killed by a sword stroke.

Major Dunnett was ridden down to the turf. A seventeen-year-old Lieutenant was caught by two Dragoons. The first blinded him with a slashing backstroke, the second stabbed into his chest. Still the horsemen came. Their horses stank with saddlesores because they had been ridden too hard, but they had been trained to this work. A Rifleman’s cheek Was flensed from his face and his mouth bubbled with blood and saliva. The French grunted as they hacked. This was a cavalryman’s paradise; broken infantry and firm ground.

The new Lieutenant still shouted as he climbed. “Rifles! To me! To me! To me!” The chasseur must have heard him, for he turned his big black horse and spurred towards the Englishman.

The Lieutenant saw him coming, slung his empty rifle, and drew his sabre. “Come on, you bastard!”

The chasseur held his own sabre in his right hand and, to make his killing cut easy, directed his horse to the left of the Rifleman. The Lieutenant waited to swing his curved blade at the horse’s mouth. The cut would stop its charge dead, making it rear and twist away. He had seen off more horsemen than he could remember with such a stroke. The skill lay in the timing, and the Lieutenant hoped that the horse’s panicked evasion would shake the rider loose. He wanted that clever chasseur dead.
