Lapped in this fatal security, Egmont not only forgot his fears, but unfortunately succeeded in inspiring Count Horn with a portion of his confidence.  That gentleman had still remained in his solitary mansion at Weert, notwithstanding the artful means which had been used to lure him from that “desert.”  It is singular that the very same person who, according to a well-informed Catholic contemporary, had been most eager to warn Egmont of his danger, had also been the foremost instrument for effecting the capture of the Admiral.  The Seigneur de Billy, on the day after his arrival from Madrid, had written to Horn, telling him that the King was highly pleased with his services and character.  De Billy also stated that he had been commissioned by Philip to express distinctly the royal gratitude for the Count’s conduct, adding that his Majesty was about to visit the Netherlands in August, and would probably be preceded or accompanied by Baron Montigny.

Alva and his son Don Ferdinando had soon afterwards addressed letters from Gerverbiller (dated 26th and 27th July) to Count Horn, filled with expressions of friendship and confidence.  The Admiral, who had sent one of his gentlemen to greet the Duke, now responded from Weert that he was very sensible of the kindness manifested towards him, but that for reasons which his secretary Alonzo de la Loo would more fully communicate, he must for the present beg to be excused from a personal visit to Brussels.  The secretary was received by Alva with extreme courtesy.  The Duke expressed infinite pain that the King had not yet rewarded Count Horn’s services according to their merit, said that a year before he had told his brother Montigny how very much he was the Admiral’s friend, and begged La Loo to tell his master that he should not doubt the royal generosity and gratitude.  The governor added, that if he could see the Count in person he could tell him things which would please him, and which would prove that he had not been forgotten by his friends.  La Loo had afterward a long conversation with the Duke’s secretary Albornoz, who assured him that his master had the greatest affection for Count Horn, and that since his affairs were so much embarrassed, he might easily be provided with the post of governor at Milan, or viceroy of Naples, about to become vacant.  The secretary added, that the Duke was much hurt at receiving no visits from many distinguished nobles whose faithful friend and servant he was, and that Count Horn ought to visit Brussels, if not to treat of great affairs, at least to visit the Captain-General as a friend.  “After all this,” said honest Alonzo, “I am going immediately to Weert, to urge his lordship to yield to the Duke’s desires.”

This scientific manoeuvring, joined to the urgent representations of Egmont, at last produced its effect.  The Admiral left his retirement at Weert to fall into the pit which his enemies had been so skilfully preparing at Brussels.  On the night of the 8th September, Egmont received another most significative and mysterious warning.  A Spaniard, apparently an officer of rank, came secretly into his house, and urged him solemnly to effect his escape before the morrow.  The Countess, who related the story afterwards, always believed, without being certain, that the mysterious visitor was Julian Romero, marechal de camp.  Egmont, however, continued as blindly confident as before.
