Rifleman Cooper cut the hobble of the Quartermaster’s mule and dragged the recalcitrant beast up the road. Murray gave the mule a cut on its backside with his heavy sword, making it leap forward. “Why don’t you let it go?” he shouted at the Lieutenant.

“Because I damn well need it.” The Lieutenant ordered Cooper to take the mule off the road and up the northern hillside to clear the field of fire for Dunnett’s two companies. The greenjackets were trained to the skirmish line, to the loose chain of men who took shelter and sniped at the enemy, but on this retreat the men in green formed ranks as tight as the redcoats and used their rifles for volley fire.

“Form! Form!” Sergeant Williams was shouting at Murray’s company. The French advanced gingerly to the bridge. There were perhaps a hundred of them, a vanguard mounted on horses that looked desperately tired and weak. No horse should have been campaigning in this weather and on these bitter mountain roads, but the Emperor had launched these Frenchmen to finish off the British army and so the horses would be whipped to death if that meant victory. Their hooves were wrapped in rags to give purchase on slippery roads.

“Rifles! Fix swords!” Dunnett shouted. The long sword-bayonets were tugged from scabbards and clipped onto the muzzles of the loaded rifles. The command was probably unnecessary. The French did not look as though they would try another charge, but fixed swords was the rule for when facing cavalry, so Dunnett ordered it.

The Lieutenant loaded his rifle. Captain Murray wiped moisture from the blade of his Heavy Cavalry sword which, like the Lieutenant’s rifle, was an eccentricity. Rifle officers were expected to wear a light curved sabre, but Murray preferred the straight-bladed trooper’s sword that could crush a man’s skull with its weight alone.
