The latter of these legislators completely changed the forms of the government; he revived the ancient privileges destroyed by Charles V., and took all preliminary measures for forcing the various provinces to join with the city of Ghent in forming a federative republic. The states-general and the Prince of Orange were alarmed, lest these troubles might lead to a renewal of the anarchy from the effects of which the country had but just obtained breathing-time. Ryhove consented, at the remonstrance of the Prince of Orange, to release the duke of Arschot; but William was obliged to repair to Ghent in person, in the hope of establishing order. He arrived on the 29th of December, and entered on a strict inquiry with his usual calmness and decision. He could not succeed in obtaining the liberty of the other prisoners, though he pleaded for them strongly. Having severely reprimanded the factious leaders, and pointed out the dangers of their illegal course, he returned to Brussels, leaving the factious city in a temporary tranquillity which his firmness and discretion could alone have obtained. The archduke Mathias, having visited Antwerp, and acceded to all the conditions required of him, made his public entry into Brussels on the 18th of January, 1578, and was installed in his dignity of governor-general amid the usual fetes and rejoicings. Don John of Austria was at the same time declared an enemy to the country, with a public order to quit it without delay; and a prohibition was issued against any inhabitant acknowledging his forfeited authority. War was now once more openly declared; some fruitless negotiations having afforded a fair pretext for hostilities. The rapid appearance of a numerous army under the orders of Don John gave strength to the suspicions of his former dissimulation. It was currently believed that large bodies of the Spanish troops had remained concealed in the forests of Luxemburg and Lorraine; while several regiments, which had remained in France in the service of the League, immediately re-entered the Netherlands. Alexander Farnese, prince of Parma, son of the former stadtholderess, came to the aid of his uncle, Don John, at the head of a large force of Italians; and these several reinforcements, with the German auxiliaries still in the country, composed an army of twenty thousand men. The army of the states-general was still larger; but far inferior in point of discipline. It was commanded by Antoine de Goignies, a gentleman of Hainault, and an old soldier of the school of Charles V.
