Alexander saw the precarious condition of the desecrated Church, and resigning himself to his fate, determined to seek safety in flight. But the enemy had evidently foreseen the contingency, and every disposition had been made to prevent the escape of the Pontiff.

A cordon of troops was drawn around the citadel; these were doubled after nightfall, and so great was the importance which the Emperor attached to the Pope's capture, that none but Germans were detailed on the service, for Frederic had little confidence in his Italian mercenaries.

The gigantic castle of Saint Angelo rose towards heaven, and the gilded statue of St. Michael glittered upon its summit. The helmeted sentinels in full armor, their lances poised upon their shoulders, paced the bridge with measured tread. At times they looked towards the castle, then upon the river, and then towards the distant horizon; for they knew that the Pope would seek to escape.

Further on, a strong detachment of soldiers were sleeping on the ground, with their helmets and lances carefully piled near them. Among these might have been seen the knight Goswin and the tailor Guerrazzi, who were engaged in earnest conversation.

The frankness of the worthy German found little to sympathize with in the crafty Italian; but Guerrazzi, who never lost the opportunity of showing his zeal for the Emperor, had offered to keep him company and share the fatigues of the night-watch. Of course no fault could be found with this, but Goswin looked upon his companion much as a dog would on a cat which fawned upon him. The German, it is true, had a very limited intellect, but his natural good sense taught him that the Italian was full of tricks and artifice.

At first he paid no attention whatever to Guerrazzi, as if to show him that his presence was a matter of perfect indifference, and he walked up and down the banks of the Tiber immersed in thought.

But Goswin was not a philosopher, and could not remain for hours at a time in a revery, so he very soon began to weary of the silence, and finally approached Guerrazzi.

"A very fine evening!" said the knight, opening the conversation like one who did not know what to say.

"We are in the month of July, noble sir, and at this season, I think, the custom ought to be to sleep all day and work at night."

"Sleep all day!--you?" said Goswin; "did I not see you on the square, haranguing the Romans, and working them up as a baker kneads soft dough? And if I mistake not, you were at the allied camp before daybreak? Don't you sleep either day or night?"
