n, which was not
so deep and only half as wide, so that a force thus, sent through these
dangerous shallows, might take possession of Duiveland and lay siege to
Zierickzee, in the very teeth of the Zealand fleet, which would be unable
to sail near enough to intercept their passage.

The Commander determined that the enterprise should be attempted. It was
not a novelty, because Mondragon, as we have seen, had already most
brilliantly conducted a very similar expedition. The present was,
however, a much more daring scheme. The other exploit, although
sufficiently hazardous, and entirely, successful, had been a victory
gained over the sea alone. It had been a surprise, and had been effected
without any opposition from human enemies. Here, however, they were to
deal, not only with the ocean and darkness, but with a watchful and
determined foe. The Zealanders were aware that the enterprise was in
contemplation, and their vessels lay about the contiguous waters in
considerable force. Nevertheless, the determination of the Grand
Commander was hailed with enthusiasm by his troops. Having satisfied
himself by personal experiment that the enterprise was possible, and that
therefore his brave soldiers could accomplish it, he decided that the
glory of the achievement should be fairly shared, as before, among the
different nations which served the King.

After completing his preparations, Requesens came to Tholen, at which
rendezvous were assembled three thousand infantry, partly Spaniards,
partly Germans, partly Walloons. Besides these, a picked corps of two
hundred sappers and miners was to accompany the expedition, in order that
no time might be lost in fortifying themselves as soon as they had seized
possession of Schouwen. Four hundred mounted troopers were, moreover,
stationed in the town of Tholen, while the little fleet, which had been
prepared at Antwerp; lay near that city ready to co-operate with the land
force as soon as they, should complete their enterprise. The Grand
Commander now divided the whole force into two parts: One half was to
remain in the boats, under the command of Mondragon; the other half,
accompanied by the two hundred pioneers, were to wade through the sea
from Philipsland to Duiveland and Schouwen. Each soldier of this
detachment was provided with a pair of shoes, two pounds of powder, and
rations for three days in a canvas bag suspended at his neck. The leader
of this expedition was Don Osorio d'Ull
