The ink was barely dry on the edict of Poitiers when international tensions and domestic hostilities threatened once again to break up the delicate peace settlement that Henry III and Catherine de Medici had worked so hard to achieve. The revolt in the Netherlands intensified over the summer, when Philip II's governor-general, his half-brother Don John of Austria, violated the pacification of Ghent by seizing the citadel of Namur on 24 July. As a result, the Dutch States-General doubled their efforts to attract the support of the duke of Anjou to their cause. Two Dutch agents, Aubigny and Mansart, were once again despatched to France in October 1577 for this purpose. The issue was complicated, however, by the efforts of the duke of Guise to aid Don John with troops, munitions, and supplies. Guise met Don John in late September and offered to send him whatever forces he could muster from those released by the peace of Bergerac. The States pleaded with Henry III not to allow Guise to aid Don John, while at the same time Aubigny and Mansart presented Anjou with a gift of three Flemish tapestries from the States. Anjou, who was visiting his sister Marguerite in La Fère at the time, diplomatically refused the tapestries at Henry's request. Nevertheless, he reiterated to the Dutch that he had always favored their cause and would continue to support them.
