Even the States of Utrecht passed a similar resolution and allowed the raising of "Waardgelders" in the city of Utrecht. But after a while Maurice started to undermine the Oldenbarnevelt party by "turning" city governments in Holland and Gelderland (like Nijmegen and Brielle, both garrison towns) that supported the Remonstrant cause, by intimidation with the help of States-Army troops, thereby reducing Oldenbvarnevelt's majority in the States Also the States-Army garrisons of several towns refused to obey the Holland "Gecommitteerde Raden" (Executive of the States). Then, in March of 1618, Maurice began to mobilize the five "Counter-Remonstrant" provinces in the States General. In May 1618 he managed to bring over the States of Overijssel (previously a Holland ally) to the Counter-Remonstrant side. The decision to convene a National Synod was then reaffirmed by a stronger majority in the States General, over the objection of the Holland delegation, led by Grotius. Grotius objected to the fact that the decision was not unanimous in a matter that the Union of Utrecht explicitly reserved for the individual, sovereign, provinces. In his view majority voting was only allowed in matters that had been delegated to the States General, like defense. Maurice objected in a speech to the States of Overijssel in May 1618 that the unrest about the religious controversy had become so serious that it had become a matter of internal security of the entire country, and therefore within the remit of the States General. On 9 July 1618 the States General began deliberating the disbandment of the "Waardgelder" troops in Holland and Utrecht, over the objection of those provinces. The usual standpoints were exchanged and the States General overruled Holland and Utrecht by five votes to two. The States General then authorized the stadtholder to disband the "Waardgelders" in the city of Utrecht. In desperation Oldenbarnevelt sent Grotius and Hogerbeets to Utrecht province to summon the commanders of the federal troops in that province that were paid by Holland (i.e. most of them) to obey the States of Holland and not the stadtholder. This action was later to be the main article in the indictment before the court that tried Oldenbarnevelt, Grotius and the other "conspirators" for high treason.
