In the month of February, 1590, Maurice, being then at the castle of Voorn in Zeeland, received a secret visit from a boatman, Adrian van der Berg by name, who lived at the village of Leur, eight or ten miles from Breda, and who had long been in the habit of supplying the castle with turf.  In the absence of woods and coal mines, the habitual fuel of the country was furnished by those vast relics of the antediluvian forests which abounded in the still partially submerged soil.  The skipper represented that his vessel had passed so often into and out of the castle as to be hardly liable to search by the guard on its entrance.  He suggested a stratagem by which it might be possible to surprise the stronghold.

The prince approved of the scheme and immediately consulted with Barneveld.  That statesman at once proposed, as a suitable man to carry out the daring venture, Captain Charles de Heraugiere, a nobleman of Cambray, who had been long in the service of the States, had distinguished himself at Sluys and on other occasions, but who had been implicated in Leicester’s nefarious plot to gain possession of the city of Leyden a few years before.  The Advocate expressed confidence that he would be grateful for so signal an opportunity of retrieving a somewhat damaged reputation.  Heraugiere, who was with his company in Voorn at the moment, eagerly signified his desire to attempt the enterprise as soon as the matter was communicated to him; avowing the deepest devotion to the house of William the Silent and perfect willingness to sacrifice his life, if necessary, in its cause and that of the country.  Philip Nassau, cousin of Prince Maurice and brother of Lewis William, governor of Gorcum, Dorcum, and Lowenstein Castle and colonel of a regiment of cavalry, was also taken into the secret, as well as Count Hohenlo, President Van der Myle and a few others; but a mystery was carefully spread and maintained over the undertaking.

Heraugiere selected sixty-eight men, on whose personal daring and patience he knew that he could rely, from the regiments of Philip Nassau and of Famars, governor of the neighbouring city of Heusden, and from his own company.  Besides himself, the officers to command the party were captains Logier and Fervet, and lieutenant Matthew Held.  The names of such devoted soldiers deserve to be commemorated and are still freshly remembered by their countrymen.

On the 25th of February, Maurice and his staff went to Willemstad on the Isle of Klundert, it having been given out on his departure from the Hague that his destination was Dort.  On the same night at about eleven o’clock, by the feeble light of a waning moon, Heraugiere and his band came to the Swertsenburg ferry, as agreed upon, to meet the boatman.  They found neither him nor his vessel, and they wandered about half the night, very cold, very indignant, much perplexed.  At last, on their way back, they came upon the skipper at the village of Terheyde, who made
