To this document the Prince replied in August, having paid in the meantime but little heed to its precepts. Now that the Emperor, who at first was benignant, had begun to frown on his undertaking, he did not slacken in his own endeavours to set his army on foot. One by one, those among the princes of the empire who had been most stanch in his cause, and were still most friendly to his person, grew colder as tyranny became stronger; but the ardor of the Prince was not more chilled by their despair than by the overthrow at Jemmingen, which had been its cause. In August, he answered the letter of the Emperor, respectfully but warmly. He still denounced the tyranny of Alva and the arts of Granvelle with that vigorous eloquence which was always at his command, while, as usual, he maintained a show of almost exaggerated respect for their monarch. It was not to be presumed, he said, that his Majesty, "a king debonair and bountiful," had ever intended such cruelties as those which had been rapidly retraced in the letter, but it was certain that the Duke of Alva had committed them all of his own authority. He trusted, moreover, that the Emperor, after he had read the "Justification" which the Prince had recently published, would appreciate the reason for his taking up arms. He hoped that his Majesty would now consider the resistance just, Christian, and conformable to the public peace. He expressed the belief that rather than interpose any hindrance, his Majesty would thenceforth rather render assistance "to the poor and desolate Christians," even as it was his Majesty's office and authority to be the last refuge of the injured.
