"Our children!" he cried; "are we, then, slaves, that we must needs send you our little ones as hostages? Guards, here! Shoot me down this brigand who bids me surrender your children to him!"

Bolts flew whizzing from the cross-bows; the Free-lance shook his iron gauntlet at the Syndic, and galloped down the ridge unharmed. The Syndic forgot his gout in his wrath, and bade the hill-men hold their own till their roofs crumbled about their ears.

Then began a close siege of the castello; but on the fourth day Frate Agnolo passed boldly through the lines of the enemy, and was admitted through the massive stone gateway which was too narrow for the entrance of either cart or waggon. Great was the joy of the hill-men as the Brother appeared among them. He, they knew, would give them wise counsel and stout aid in the moment of danger.

When they told him of the pledge for which the besiegers asked, he only smiled and shook his head. "Be of good cheer," he said, "God and His Angels have us in their keeping."

Thoughtfully he ascended the steep streets to the piazza, and, entering the Cathedral, he remained there for a long while absorbed in prayer. And as he prayed his face brightened with the look of one who hears joyful news, and when he rose from his knees he went to the house of the Syndic, and spoke with him long and seriously.

At sunset that day a man-at-arms went forth from the gates of the castello with a white flag to the beleaguering lines, and demanded to be taken into the presence of the captain. To him he delivered this message from the Syndic: "To-morrow in the morning the gate of Spinalunga will be thrown open, and all the children of our town who are not halt or blind or ailing shall be sent forth. Come and choose the twenty you would have as hostages."

By the camp-fires that night the Free-lances caroused loud and long; but in the little hill-town the children slept sound while the men and women prayed with pale stern faces. An hour after midnight all the garrison from the towers and all the strong young men assembled in the square. They were divided into two bands, and were instructed to descend cautiously by rope-ladders into the ravine on the eastern side of the town. Thence without sound of tongue or foot they were to steal through the darkness till they had reached certain positions on the flanks of the besiegers, where they were to wait for the signal of onset. Frate Agnolo gave each of them his blessing, as one by one they slid over the wall on to the rope-ladders and disappeared in the blackness of the ravine. Noiselessly they marched under the walls of the town till they reached their appointed posts, and there they lay hidden in the woods till morning.

The Free-lances were early astir. As the first ray of golden light streamed over the pine woods on to the ridge and the valley, the bells of the Cathedral began to ring; the heavy gate of the castello was flung open, and the children trooped out laughing and gay, just as they had burst into the square a few months ago, for this, they were told, was to be a great feast and holiday. As they issued through the deep stone archway they filed to right or left, and drew up in long lines across the width of the ridge. Then raising their childish voices in a simple hymn, they all moved together down the rough slope to the lines of the besiegers. Brother Agnolo, holding a plain wooden cross high above his head, led the way, singing joyously.

It was a wonderful sight in the clear shining air of the hills, and hundreds of women weeping silently on the walls crowded together to watch it; and as they watched they held their breath, for suddenly in the golden light of the morning they saw that behind each child there was a great white-winged Angel with a fiery spear.

Then, as that throng of singing children and shining spirits swept down upon the Free-lances, a wild cry of panic arose from the camp. The eight hundred horsemen turned in dismay, and plunged through the ranks of the men-at-arms, and the mercenaries fell back in terror and confusion, striking each other down and trampling the wounded underfoot in their frantic efforts to escape. At that moment the hill-men who were lying in ambush on each flank bore down on the bewildered multitude, and hacked and hewed right and left till the boldest and hardiest of the horsemen broke and fled, leaving their dead and dying on the field.
