The proceedings were kept secret from the public and, as a matter of course, there had been conflicting rumours from day to day as to the probable result of these great state trials. In general however it was thought that the prisoner would be acquitted of the graver charges, or that at most he would be permanently displaced from all office and declared incapable thenceforth to serve the State. The triumph of the Contra-Remonstrants since the Stadholder had placed himself at the head of them, and the complete metamorphosis of the city governments even in the strongholds of the Arminian party seemed to render the permanent political disgrace of the Advocate almost a matter of certainty.

The first step that gave rise to a belief that he might be perhaps more severely dealt with than had been anticipated was the proclamation by the States-General of a public fast and humiliation for the 17th April.

In this document it was announced that "Church and State—during several years past having been brought into great danger of utter destruction through certain persons in furtherance of their ambitious designs—had been saved by the convocation of a National Synod; that a lawful sentence was soon to be expected upon those who had been disturbing the Commonwealth; that through this sentence general tranquillity would probably be restored; and that men were now to thank God for this result, and pray to Him that He would bring the wicked counsels and stratagems of the enemy against these Provinces to naught."

All the prisoners were asked if they too would like in their chambers of bondage to participate in the solemnity, although the motive for the fasting and prayer was not mentioned to them. Each of them in his separate prison room, of course without communication together, selected the 7th Psalm and sang it with his servant and door-keeper.

From the date of this fast-day Barneveld looked upon the result of his trial as likely to be serious.

Many clergymen refused or objected to comply with the terms of this declaration. Others conformed with it greedily, and preached lengthy thanksgiving sermons, giving praise to God that, He had confounded the devices of the ambitious and saved the country from the "blood bath" which they had been preparing for it.

The friends of Barneveld became alarmed at the sinister language of this proclamation, in which for the first time allusions had been made to a forthcoming sentence against the accused.

Especially the staunch and indefatigable du Maurier at once addressed himself again to the States-General. De Boississe had returned to France, having found that the government of a country torn, weakened, and rendered almost impotent by its own internecine factions, was not likely to exert any very potent influence on the fate of the illustrious prisoner.

The States had given him to understand that they were wearied with his perpetual appeals, intercessions, and sermons in behalf of mercy. They made him feel in short that Lewis XIII. and Henry IV. were two entirely different personages.

Du Maurier however obtained a hearing before the Assembly on the 1st May, where he made a powerful and manly speech in presence of the Prince, urging that the prisoners ought to be discharged unless they could be convicted of treason, and that the States ought to show as much deference to his sovereign as they had always done to Elizabeth of England. He made a personal appeal to Prince Maurice, urging upon him how much it would redound to his glory if he should now in generous and princely fashion step forward in behalf of those by whom he deemed himself to have been personally offended.
