Andover laughed. “You’ve turned over a new leaf, Lewis. Your energy puts us all to shame. I wish I had your physical gifts, my son. The worst of being long and lanky in a place like this is that you’re always as stiff as a poker. I shall die of sciatica before I am forty. But upon my word it is queer meeting you here in the loneliest spot in creation. When I saw you in town before I came out, you were going into Parliament or some game of that kind. Then I heard that you had been out here, and gone back; and now for no earthly reason I waken up one fine morning to find you being potted at before my gate. You’re as sudden as Marker, and a long chalk more mysterious.”

Lewis looked grave. “I wish Marker were only as simple as me, or I as sudden as him. It’s a gift not learned in a day. Anyhow I’m here, and we’ve got a day’s sport before us. Hullo, the ball seems about to open.” Little puffs of smoke and dust were rising from beyond the wall, and on the heavy air came the faint ping-ping of rifles.

Andover stretched himself elaborately. “Lord alive, but this is absurd. What do these beggars expect to do? They can’t shell a fort with stolen expresses.”

The two men went up to the edge of the wall and looked over the plateau. A hundred yards off stood a group of tribesmen formed in some semblance of military order, each with a smoking rifle in his hand. It was like a parody of a formation, and Andover after rubbing his eyes burst into a roar of laughter.

“The beggars must be mad. What in heaven’s name do they expect to do, standing there like mummies and potting at a stone wall? There’s two more companies of them over there. It isn’t war, it’s comic opera.” And he sat down, still laughing, on the edge of a gun-case to put on the boots which his orderly had brought.

It was comic opera, but the tinge of melodrama was not absent. When a sufficient number of rounds had been fired, the tribesmen, as if acting on half-understood instructions from some prehistoric manual, slung their rifles on their shoulders and came on. The fire from the fort did not stop them, though it broke their line. In a minute they were clutching at every hand-grip and foothold on the wall, and Andover with a beaming face directed the disposition of his men.

Forza is built of great, rough stones, with ends projecting in places cyclopean-wise, which to an active man might give a foothold. The little garrison was at its posts, and picked the men off with carbines and revolvers, and in emergencies gave a brown chest the straight bayonet-thrust home. The tribesmen fought like fiends, scrambling up silently with long knives between their teeth, till a shot found them and they rolled back to die on the sand at the foot. Now and again a man would reach the parapet and spring down into the courtyard. Then it was the turn of Andover and Lewis to account for him, and they did not miss. One man with matted hair and beard was at Lewis’s back before he saw him. A crooked knife had nearly found that young man’s neck, but a lucky twisting aside saved him. He dodged his adversary up and down the yard till he got his pistol from his inner pocket. Then it was his turn to face about. The man never stopped and a ball took him between the eyes. He dropped dead as a stone, and his knife flying from his hand skidded along the sand till it stopped with a clatter on the stones. The sound in the hot sulphurous air grated horribly, and Lewis clapped his hands to his ears to find that he too had not come off scathless. The knife had cut the lobe, and, bleeding like a pig, he went in search of water.

The assailants seemed prepared to find paradise speedily, for they were not sparing with their lives. The attacking party was small, and apparently there was no reserve, for in all the wide landscape there was no sign of man. Then for no earthly reason the assault was at an end. One by one the men dropped back and disappeared from the plateau. There was no overt signal, no sound; but in a little the annoyed garrison were looking at vacancy and one another.

“This is the devil’s own business,” said Andover, rubbing his eyes. The men, too astonished to pick off stragglers, allowed the enemy to melt into space; then they set themselves down with rifles cuddled up to their chins, and stared at Andover.

“It beats me,” said that disturbed man. “How many killed?”
