It was from Leyden that the chief opposition came to a synod, by which a great attempt was to be made towards subjecting the new commonwealth to a masked theocracy; a scheme which the States of Holland had resisted with might and main. The Calvinistic party, waxing stronger in Leyden, although still in a minority, at last resolved upon a strong effort to place the city in the hands of that great representative of Calvinism, the Earl of Leicester. Jacques Volmar, a deacon of the church, Cosmo de Pescarengis, a Genoese captain of much experience in the service of the republic, Adolphus de Meetkerke, former president of Flanders, who had been, by the States, deprived of the seat in the great council to which the Earl had appointed him; Doctor Saravia, professor of theology in the university, with other deacons, preachers, and captains, went at different times from Leyden to Utrecht, and had secret interviews with Leicester.
A plan was at last agreed upon, according to which, about the middle of October, a revolution should be effected in Leyden. Captain Nicholas de Maulde, who had recently so much distinguished himself in the defence of Sluys, was stationed with two companies of States’ troops in the city. He had been much disgusted—not without reason—at the culpable negligence through which the courageous efforts of the Sluys garrison had been set at nought, and the place sacrificed, when it might so easily have been relieved; and he ascribed the whole of the guilt to Maurice, Hohenlo, and the States, although it could hardly be denied that at least an equal portion belonged to Leicester and his party. The young captain listened, therefore, to a scheme propounded to him by Colonel Cosine, and Deacon Volmar, in the name of Leicester. He agreed, on a certain day, to muster his company, to leave the city by the Delft gate—as if by command of superior authority—to effect a junction with Captain Heraugiere, another of the distinguished malcontent defenders of Sluys, who was stationed, with his command, at Delft, and then to re-enter Leyden, take possession of the town-hall, arrest all the magistrates, together with Adrian van der Werff, ex-burgomaster, and proclaim Lord Leicester, in the name of Queen Elizabeth, legitimate master of the city. A list of burghers, who were to be executed, was likewise agreed upon, at a final meeting of the conspirators in a hostelry, which bore the ominous name of ’The Thunderbolt.’ A desire had been signified by Leicester, in the preliminary interviews at Utrecht, that all bloodshed, if possible, should be spared, but it was certainly an extravagant expectation, considering the, temper, the political convictions, and the known courage of the Leyden burghers, that the city would submit, without a struggle, to this invasion of all their rights. It could hardly be doubted that the streets would run red with blood, as those of Antwerp had done, when a similar attempt, on the part of Anjou, had been foiled.
