Then suddenly the cleft was filled with screaming men, brandishing swords and rifles as they appeared in the light of the oil lamps.
Twenty-two rifles spat out as one and the front rank fell. It was rapid fire now.
The bodies of the dead and dying filled the cleft, Afghans were using the bodies as protection as they tried to return fire. Suddenly, first one lamp was shot out and then the second, and the cleft was in darkness.
David lit the gunpowder fuse and said a silent prayer. The flame streaked across the ground until it reached the brushwood, briefly flared and then went out. It seemed he had failed, then one or two small flames flickered, the oil caught and with a whoosh the night lit up.
About 50 Afghans were cautiously advancing out of the Cleft. The rifles cracked out again. David was working the bolt as fast as he could; at this range it was impossible to miss. When the rifle fell empty, he picked up his pistol and fired that into the throng. When that fell empty, he used his belt pistol.
The Afghans were screaming and dying, treading on their own comrades as they tried to escape back down the cleft, the darkness swallowing them up as they withdrew. The riflemen fell silent and became busy reloading their weapons.
David reloaded his, watching as two men threw more bushes onto the fire. He slipped the empty clips into his pocket. Feeling the hipflask, he drew it out and took a long swig, feeling the warmth glowing in his stomach.
Sultar climbed out and ran to check the pits. Some of the Afghan wounded were moaning or screaming, but a series of shots rang out, methodically silencing them.
More wood was added to the fire and it flared up again, illuminating a scene of carnage. David estimated there were over 80 bodies in and around the cleft entrance.
Now and then a rifle would be fired from the other end of the Cleft, the bullet whizzing high above their heads.
Sultar came back, reporting two riflemen had slight gunshot wounds, one in the arm, the other in the shoulder, and both were only grazes.
David could see the light brightening in the sky above, although it was still black down here on the valley floor.
Half an hour later, a message came down reporting that the Afghans were retreating, with bodies draped over horses.
They waited until the Cleft was lit with daylight. A rifleman went to scout the end of the Cleft, returning to say it was clear.
They then began the gruesome job of clearing up.
David stood by the re-lit cook fire drinking tea while the men stripped the bodies of valuables, weapons and ammunition.
Horses were brought and bodies draped over them and led away.
Eventually Sultar reported 93 dead, with some having been shot three or four times. Eighty-one new Russian rifles had been collected, five of which had been hit with bullets and ruined. The rest of gathered rifles were outdated muzzleloaders. Of seven pistols recovered, five were Smith and Wesson's like his, and looked new. The other two were Colts.
He saw to the packing or the weapons and ammunition, along with the holsters for the pistols. The valuables would be in another pack.
"Without your idea for a fire, Colonel Sahib, we could have been overrun," Sultar murmured.
"But we wasn't. The men fought in the best tradition of the Gurkhas," David replied smiling.
"I very much doubt they will be back now until the spring, but of course we cannot be sure."
"I shall return to the Fort. We will need more wood to provide a fire should they return at night. The gunpowder from the muzzleloaders should be kept here. Can you spare two men to lead the pack horses back to the Fort?" David asked him.
"Of course, Colonel Sahib, I shall send the men on when we have completed here."
He sent a man to bring Kahn, while he went to make ready to depart.
David rolled up his blankets and removed the clips from his saddlebag, while someone saddled Kahn. He left his furs on the bunk, immediately feeling the change in temperature once they were off.
He mounted, and with a final wave set off in a brisk trot. Once out of the Pass he put Kahn into a canter. The horse responded eagerly, as if keen to be away from this place.
It was after one when he trotted into the Fort. At the stable he told Hanga to give him a good rub down after removing the saddle and feeding him.
Turning away, he saw Para and Hagar walking fast towards him. Once in his office, he recounted the battle to them, saying that there could have been well over a hundred casualties as the lookout had sighted bodies over some of the horses retreating. He mentioned the quantity of Russian weapons taken adding, "It's obvious that they are arming them with the intention of taking the Pass."
When they were gone, he felt his beard, looking forward to a bath and shave.
When he entered his quarters his eyes widened. The cheap furniture was gone, replaced by gleaming sideboards, a table and chairs. Two maroon leather armchairs had replaced the rocking chair, a brass coffee table lay between them. On the floor were thick Persian rugs and a chandelier with five oil lamps hung from the ceiling.
Hanga came in grinning, "This is much better now for an English gentleman like the Colonel Sahib."
David could only nod his surprise and pleasure.
The tin tub had been replaced by bigger enamel one. The clothes he had worn were gone, and a new set lay on the new brass bedstead.
After he had dressed, Hanga asked if he would like a drink. David nodded from his seat in one of the new armchairs. Hanga opened a cupboard door and removed a cut glass decanter with six matching glasses on a silver tray. He poured out a good measure handing it too him.
"I hope you left something for the Prince?" David chuckled.
After his drink he went outside taking an apple with him. Sulkie's stall was empty. Out in the paddock he reasoned.
Kahn stood in his stall, all attention on David. Hanga had brushed him down and his coat gleamed.
