While treason was thus favoring the royal arms in the north, the same powerful element, to which so much of the Netherland misfortunes had always been owing was busy in Flanders.
Towards the end of the year 1583, the Prince of Chimay, eldest son of the Duke of Aerschot, had been elected governor of that province. This noble was as unstable in character, as vain, as unscrupulous, and as ambitious as his father and uncle. He had been originally desirous of espousing the eldest daughter of the Prince of Orange, afterwards the Countess of Hohenlo, but the Duchess of Aerschot was too strict a Catholic to consent to the marriage, and her son was afterwards united to the Countess of Meghem, widow of Lan celot Berlaymont.
As affairs seemed going on prosperously for the states in the beginning, of this year, the Prince of Chimay had affected a strong inclination for the Reformed religion, and as governor of Bruges, he had appointed many members of that Church to important offices, to the exclusion of Catholics. By so decided a course, he acquired the confidence of the patriot party and at the end of the year he became governor of Flanders. No sooner was he installed in this post, than he opened a private correspondence with Parma, for it was his intention to make his peace with the King, and to purchase pardon and advancement by the brilliant service which he now undertook, of restoring this important province to the royal authority. In the arrangement of his plans he was assisted by Champagny, who, as will be recollected, had long been a prisoner in Ghent, but whose confinement was not so strict as to prevent frequent intercourse with his friends without. Champagny was indeed believed to be the life of the whole intrigue. The plot was, however, forwarded by Imbize, the roaring demagogue whose republicanism could never reconcile itself with what he esteemed the aristocratic policy of Orange, and whose stern puritanism could be satisfied with nothing short of a general extermination of Catholics. This man, after having been allowed to depart, infamous and contemptible, from the city which he had endangered, now ventured after five years, to return, and to engage in fresh schemes which were even more criminal than his previous enterprises. The uncompromising foe to Romanism, the advocate of Grecian and Genevan democracy, now allied himself with Champagny and with Chimay, to effect a surrender of Flanders to Philip and to the Inquisition. He succeeded in getting himself elected chief senator in Ghent, and forthwith began to use all his influence to further the secret plot. The joint efforts and intrigues of Parma, Champagny, Chimay, and Imbize, were near being successful. Early, in the spring of 1584 a formal resolution was passed by the government of Ghent, to open negotiations with Parma. Hostages were accordingly exchanged, and a truce of three weeks was agreed upon, during which an animated correspondence was maintained between the authorities of Ghent and the Prince of Chimay on the one side, and the United States-general, the magistracy of Antwerp, the states of Brabant, and other important bodies on the other.
