The courier who was to take Philip’s letters to the three nobles was detained three weeks, in order to allow Armenteros, who was charged with the more important and secret despatches for the Duchess and Granvelle to reach Brussels first.  All the letters, however, were ready at the same time.  The letter of instructions for Armenteros enjoined upon that envoy to tell the Regent that the heretics were to be chastised with renewed vigor, that she was to refuse to convoke the states-general under any pretext, and that if hard pressed, she was to refer directly to the King.  With regard to Granvelle, the secretary was to state that his Majesty was still deliberating, and that the Duchess would be informed as to the decision when it should be made.  He was to express the royal astonishment that the seigniors should absent themselves from the state council, with a peremptory intimation that they should immediately return to their posts.  As they had specified no particularities against the Cardinal, the King would still reflect upon the subject.

He also wrote a private note to the Duchess, stating that he had not yet sent the letters for the three nobles, because he wished that Armenteros should arrive before their courier.  He, however, enclosed two notes for Egmont, of which Margaret was to deliver that one, which, in her opinion, was, under the circumstances, the best.  In one of these missives the King cordially accepted, and in the other he politely declined Egmont’s recent offer to visit Spain.  He also forwarded a private letter in his own hand-writing to the Cardinal.  Armenteros, who travelled but slowly on account of the state of his health, arrived in Brussels towards the end of February.  Five or six days afterwards, on the 1st March, namely, the courier arrived bringing the despatches for the seigniors.  In his letter to Orange, Egmont, and Horn, the King expressed his astonishment at their resolution to abstain from the state council.  Nevertheless, said he, imperatively, fail not to return thither and to show how much more highly you regard my service and the good of the country than any other particularity whatever.  As to Granvelle, continued Philip, since you will not make any specifications, my intention is to think over the matter longer, in order to arrange it as may seem most fitting.

This letter was dated February 19 (1564), nearly a month later therefore than the secret letter to Granvelle, brought by Armenteros, although all the despatches had been drawn up at the same time and formed parts of the same plan.  In this brief note to Granvelle, however, lay the heart of the whole mystery.
