Scarcely had the Emperor made known the conditions which he placed on the communication of the reply, than on Friday evening, 5th August, the Landgrave, going alone to the Count-palatine, Charles's minister, had begged for an immediate audience with his majesty. Charles, who did not care about it, pretended to be busy, and had put off Philip until the following Sunday.[727] But the latter answered that he could not wait; that his wife, who was dangerously ill, entreated him to return to Hesse without delay; and that, being one of the youngest princes, the meanest in understanding, and useless to Charles, he humbly begged his majesty would permit him to leave on the morrow. The Emperor refused. [727] Cum imperator dilationem respondendi astu quodam accepisset. (Corp. Ref. ii. pp. 254, 276.) [Sidenote: THE EMPEROR'S UNEASINESS.] We may well understand the storms this refusal excited in Philip's mind: but he knew how to contain himself; never had he appeared more tranquil; during the whole of Saturday (6th August), he seemed occupied only with a magnificent tourney in honour of the Emperor and of his brother Ferdinand.[728] He prepared for it publicly; his servants went to and fro, but under that din of horses and of armour, Philip concealed very different designs. "The Landgrave conducts himself with very great moderation," wrote Melancthon to Luther, the same day.[729] "He told me openly that, to preserve peace, he would submit to conditions still harder than those which the Emperor imposes on us, and whatever he could accept without dishonouring the Gospel, he would do so." [728] Ad ludos equestres in honorem Cæsari instituendos publice sese apparavit. (Seck. ii. p. 172.) [729] Landgravius valde moderate se gerit. (Corp. Ref. ii. p. 254.) Yet Charles was not at ease. The Landgrave's demand pursued him; all the Protestants might do the same, and even quit Augsburg unexpectedly. The clue, that he had hitherto so skilfully held in his hands, was perhaps about to be broken: it was better to be violent than ridiculous. The Emperor therefore resolved on striking a decisive blow. The Elector, the princes, the deputies, are still in Augsburg: he must at every risk prevent them from leaving it. Such were the heavy thoughts that on the night of the 6th August, while the Protestants were calmly sleeping,[730] banished repose from Charles's eyes; and which made him hastily arouse the councillors of Augsburg, and send his messengers and soldiers through the streets of the city. [730] Ego vero somno sopitus dulciter quiescebam. (Corp. Ref. ii. p. 273.) The Protestant princes were still slumbering, when they received, on the part of the Emperor, the unexpected order to repair immediately to the Hall of the Chapter.[731] [731] Mane facto Cæsar......convocavit nostros principes. (Ibid, p. 277; Bruck, Apol. p. 79.) [Sidenote: PROTESTANT FIRMNESS.]
