Meanwhile all was confusion. The States-General withdrew from Brussels to Antwerp; and William, finding that Matthias was useless, began negotiations with France, England and Germany in the hope of finding in this emergency some other foreign prince ready to brave the wrath of Philip by accepting the suzerainty of the Netherlands. The Duke of Anjou, brother of the French king, was the favoured candidate of the Catholic party; and William, whose one aim was to secure the aid of a powerful protector in the struggle against Spain, was ready to accept him. Anjou at the head of an army of 15,000 men crossed the frontier at Mons, July 12; and, on the following August 13, a treaty was agreed upon between him and the States-General, by which the French duke, with the title of Defender of the Liberties of the Netherlands, undertook to help the States to expel the Spaniards from the Low Countries.

In vain did Orange, who throughout his later life was a genuine and earnest advocate of religious toleration, strive to the utmost of his powers and with untiring patience to allay the suspicions and fears of the zealots. John Casimir at Ghent, in the fervour of his fanatical Calvinism, committed acts of violence and oppression, which had the very worst effect in the Walloon provinces. In this part of the Netherlands Catholicism was dominant; and there had always been in the provinces of Hainault, Artois, and in the southern districts generally, a feeling of distrust towards Orange.
