Then, when we had breakfasted on the food that we had brought with us from the fortress, we called in all the sentries save the two by the Gate of Sand, and hid them among the stones and bushes, all within an easy rifle-shot of the entrance to the water-cavern. I bade the two I had left by the gate tell the Governor that all was well, and, when he had ridden by, to mix with the soldiers and tell those who were for me to separate from the others as soon as they heard my signal-cry, and then to wait for the English captain.

For nearly an hour we sat and watched for the coming of the enemy, and then at last we saw a troop of horse come up out of the valley round the end of the fortress. After them came some officers on horseback, with the Governor riding at their head, and then another troop of horse, in all about three hundred men. The first troop, led by the Governor and his officers, came on towards the Sayacusca, and the others halted and spread themselves out along the ridge that runs round it. When they saw the empty hole and the steps leading down into the darkness, they all crowded round, peering down into it. Then two lanterns were lighted and some of them went down.

They had all dismounted from their horses and were indulging their curiosity without suspicion. I waited till they were nearly all in my trap, and then came the moment to close it. My long, wailing cry rang out loud and shrill through the hollow, and was taken up by my men in hiding, and in an instant all was confusion. I heard my name shouted from one to the other, and saw more than half of the troopers in the hollow leave their ranks and gallop away towards the plain. Then I took aim at a trooper who was watching the officer's horses, and fired. The bullet struck his horse, and it reared up and threw him, and then fell and lay kicking on the ground. At this all the others took fright and broke loose and galloped away in all directions. At the same instant the rifles of my men began cracking all round, and saddle after saddle was emptied as the bullets found their marks.

'I'm going to catch one of those horses,' said Hartness suddenly to me, 'then I'll ride out and bring those other fellows up and show them what to do. That'll be more in my line than this sort of work. Good-bye; you will see or hear of me again before long.'

The next moment he was gone, and I had not fired many more shots before I saw him, mounted on one of the officers' horses, galloping through the hollow towards the ridge. All this time none of my men had shown themselves, and the constant stream of shots coming from all sides of them had thrown the Governor's troops into utter confusion. The officers were shouting orders which no one listened to, the horses were galloping wildly about, rearing and plunging with the pain of their wounds, and many of the soldiers had already taken to flight, believing, in their panic, that the hollow was full of hidden enemies.

We kept up the fire from our hiding-places until we heard shouts and cheers coming from the ridge, and I looked and saw Hartness with a drawn sword in his hand, leading a body of some hundred and fifty troopers down into the hollow.

Now I saw that we should be able to end the battle quickly, so I sent up my signal-cry again and called for my own men to come out. Then I pulled the rope and released the chain, and ran out towards my men, shouting to them to close round the entrance to the water-cavern and shoot all who tried to get out. Some three or four sought to escape and were shot, and then the rest, seeing my men running at them with the bayonet, and the other troopers coming up, led by a stranger, lost heart, and crowded back into the cleft, firing their revolvers wildly as they went.

The next moment we heard cries of terror coming up out of the darkness, mingled with the rushing of water, and the Governor, followed by about six of his officers, came leaping up the steps to find a line of bayonets drawn up across the mouth. With the waters surging up behind them, and the bayonets in front of them, there was nothing for them but surrender or death.

Hartness, who had now dismounted, ordered the men to fall back a pace, and, as they did so, he went through the line with his sword in one hand and a revolver in the other, and said to the Governor,—

'Señor, will you yield or go back down yonder?'
