Out of the confused mass of documents appertaining to the trial, a few generalizations can be made which show the nature of the attack upon him. He was accused of having permitted Arminius to infuse new opinions into the University of Leyden, and of having subsequently defended the appointment of Vorstius to the same place. He had opposed the National Synod. He had made drafts of letters for the King of Great Britain to sign, recommending mutual toleration on the five disputed points regarding predestination. He was the author of the famous Sharp Resolution. He had recommended the enlistment by the provinces and towns of Waartgelders or mercenaries. He had maintained that those mercenaries as well as the regular troops were bound in time of peace to be obedient and faithful, not only to the Generality and the stadholders, but to the magistrates of the cities and provinces where they were employed, and to the states by whom they were paid. He had sent to Leyden, warning the authorities of the approach of the Prince. He had encouraged all the proceedings at Utrecht, writing a letter to the secretary of that province advising a watch to be kept at the city gates as well as in the river, and ordering his letter when read to be burned. He had received presents from foreign potentates. He had attempted to damage the character of his Excellency the Prince by declaring on various occasions that he aspired to the sovereignty of the country. He had held a ciphered correspondence on the subject with foreign ministers of the Republic. He had given great offence to the King of Great Britain by soliciting from him other letters in the sense of those which his Majesty had written in 1613, advising moderation and mutual toleration. He had not brought to condign punishment the author of 'The Balance', a pamphlet in which an oration of the English ambassador had been criticised, and aspersions made on the Order of the Garter. He had opposed the formation of the West India Company. He had said many years before to Nicolas van Berk that the Provinces had better return to the dominion of Spain. And in general, all his proceedings had tended to put the Provinces into a "blood bath." There was however no accusation that he had received bribes from the enemy or held traitorous communication with him, or that he had committed any act of high-treason. His private letters to Caron and to the ambassadors in Paris, with which the reader has been made familiar, had thus been ransacked to find treasonable matter, but the result was meagre in spite of the minute and microscopic analysis instituted to detect traces of poison in them. But the most subtle and far-reaching research into past transactions was due to the Greffier Cornelis Aerssens, father of the Ambassador Francis, and to a certain Nicolas van Berk, Burgomaster of Utrecht.
