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’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 little army.  He addressed a short harangue to them, in which he skillfully struck the chords of Spanish chivalry, and the national love of glory, and was answered with loud and enthusiastic cheers.  Don Osorio d’Ulloa then stripped and plunged into the sea immediately after the guides.  He was followed by the Spaniards, after whom came the Germans and then the Walloons.  The two hundred sappers and miners came next, and Don Gabriel Peralta, with his Spanish company; brought up the rear.  It was a wild night.  Incessant lightning, alternately revealed and obscured the progress of the midnight march through the black waters, as the anxious Commander watched the expedition from the shore, but the soldiers were 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 Spaniards were, moreover, protected, as to a large part of their bodies, by the water in which they were immersed.
