Thus the forms of justice were observed, and Montigny, a close prisoner in the tower of Segovia, was put upon trial for his life in Brussels. Certainly nothing could exceed the irony of such a process. The advocate had never seen his client, thousands of miles away, and was allowed to hold no communication with him by letter. The proceedings were instituted by a summons, addressed by the Duke of Alva to Madame de Montigny in Brussels. That unhappy lady could only appeal to the King. "Convinced," she said, "that her husband was innocent of the charges brought against him, she threw herself, overwhelmed and consumed by tears and misery, at his Majesty's feet. She begged the King to remember the past services of Montigny, her own youth, and that she had enjoyed his company but four months. By all these considerations, and by the passion of Jesus Christ, she adjured the monarch to pardon any faults which her husband might have committed." The reader can easily judge how much effect such a tender appeal was like to have upon the heart of Philip. From that rock; thus feebly smitten, there flowed no fountain of mercy. It was not more certain that Montigny's answers to the interrogatories addressed to him had created a triumphant vindication of his course, than that such vindication would be utterly powerless to save his life. The charges preferred against him were similar to those which had brought Egmont and Horn to the block, and it certainly created no ground of hope for him, that he could prove himself even more innocent of suspicious conduct than they had done. On the 4th March, 1570, accordingly, the Duke of Alva pronounced sentence against him. The sentence declared that his head should be cut off, and afterwards exposed to public view upon the head of a pike. Upon the 18th March, 1570, the Duke addressed a requisitory letter to the alcaldes, corregidors, and other judges of Castile, empowering them to carry the sentence into execution.
