Envoys from Don John also attended the diet, and requested Saint Aldegonde to furnish them with a copy of his oration. This he declined to do. While in Germany, Saint Aldegonde was informed by John Casimir that Duke Charles of Sweden, had been solicited to furnish certain ships of war for a contemplated operation against Amsterdam. The Duke had himself given information of this plot to the Prince Palatine. It was therefore natural that Saint Aldegonde should forthwith despatch the intelligence to his friends in the Netherlands, warning them of the dangers still to be apprehended from the machinations of the Catholic agents and functionaries in Amsterdam; for although the Reformation had made rapid progress in that important city since the conclusion of the Satisfaction, yet the magistracy remained Catholic. William Bardez, son of a former high-sheriff, a warm partisan of Orange and of the "religion," had already determined to overthrow that magistracy and to expel the friars who infested the city. The recent information despatched by Saint Aldegonde confirmed him in his purpose. There had been much wrangling between the Popish functionaries and those of the Reformed religion concerning the constitution of the burgher guard. The Calvinists could feel no security for their own lives, or the repose of the commonwealth of Holland, unless they were themselves allowed a full participation in the government of those important bands. They were, moreover, dissatisfied with the assignment which had been made of the churchyards to the members of their communion. These causes of discord had maintained a general irritation among the body of the inhabitants, and were now used as pretexts by Bardez for his design. He knew the city to be ripe for the overthrow of the magistracy, and he had arranged with Governor Sonoy to be furnished with a sufficient number of well-tried soldiers, who were to be concealed in the houses of the confederates. A large number of citizens were also ready to appear at his bidding with arms in their hands.
