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'Ulloa, an officer distinguished for
his experience and bravery.

On the night selected for the enterprise, that of the 27th September, the
moon was a day old in its fourth quarter, and rose a little before
twelve. It was low water at between four and five in the morning. The
Grand Commander, at the appointed hour of midnight, crossed to
Philipsland, and stood on the shore to watch the setting forth of the

quickly swallowed up in the gloom. As they advanced cautiously, two by
two, the daring adventurers found themselves soon nearly up to their
necks in the waves, while so narrow was the submerged bank along which
they were marching, that a misstep to the right or left was fatal.
Luckless individuals repeatedly sank to rise no more. Meantime, as the
sickly light, of the waning moon came forth at intervals through the
stormy clouds the soldiers could plainly perceive the files of Zealand
vessels through which they were to march, and which were anchored as
close to the flat as the water would allow. Some had recklessly stranded
themselves, in their eagerness to interrupt the passage, of the troops,
and the artillery played unceasingly from the larger vessels. Discharges
of musketry came continually from all, but the fitful lightning rendered
the aim difficult and the fire comparatively harmless while the Spaniar
