'I do not need to hear Messer Barbaresco or any other. I know what I can see for myself, what my wits tell me.' She looked at him almost slyly, for one normally so wide-eyed, and her answer all considered was a little cruel. 'Are you still unshaken in your confidence in your wits? Do you still think that you can trust them?' That was the death-blow to his passion for her, as it was the death-blow of the high hopes he is suspected of having centred in her, seeing himself, perhaps, as the husband of the Princess Valeria of Montferrat, supreme in Montferrine court and camp. It was a sword-thrust full into his vanity, which was the vital part of him. He stepped back, white to the very lips, his countenance disordered. Then, commanding himself, he bowed, and steadied his voice to answer. 'Madonna, I see that you have made your choice. My prayer will be that you may not have occasion to repent it. No doubt the troops accompanying these gentlemen of Montferrat will be your sufficient escort to Mortara, or you may join forces with Ugolino da Tenda's condotta. Although I shall be left with not more than half the men the enterprise demands, with these I must make shift to reduce Vercelli, as my duty is. Thus, madonna, you may yet owe your deliverance to me. May God be with you!' He bowed again. Perhaps he hoped still for some word to arrest him, some retraction of the injustice with which she used him. But it did not come. 'I thank you for your good intentions, my lord,' she said civilly. 'God be with you, too.' He bit his lip, then turned, and threw high that handsome golden head which he was destined to leave, some few years later, between the pillars of the Piazzetta in Venice. Thus he stalked out. All considered, it was an orderly retreat; and that was the last she ever saw of him. As the door banged, Barbaresco smacked his great thigh with his open palm and exploded into laughter. CHAPTER XIII THE OCCUPATION OF CASALE When Bellarion proclaimed his intention of raising the siege of Vercelli, he had it in mind, in view of the hopelessness of being able to reduce the place reasonably soon, to draw Theodore into the open by means of that strategic movement which Thucydides had taught him, and to which he had so often already and so successfully had recourse.
