Requesens had been long revolving in his mind the means of possessing himself of this important, island. He had caused to be constructed, a numerous armada of boats and light vessels of various dimensions, and he now came to Tholew to organize the expedition. His prospects were at first not flattering, for the gulfs and estuaries swarmed with Zealand vessels, manned by crews celebrated for their skill and audacity. Traitors, however, from Zealand itself now came forward to teach the Spanish Commander how to strike at the heart of their own country. These refugees explained to Requesens that a narrow flat extended under the sea from Philipsland, a small and uninhabited islet situate close to Tholen, as far as the shore of Duiveland. Upon this submerged tongue of land the water, during ebb-tide, was sufficiently shallow to be waded, and it would therefore be possible for a determined band, under cover of the night, to make the perilous passage. Once arrived at Duiveland, they could more easily cross the intervening creek to Schouwen, 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'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.
At times; they halted for breath, or to engage in fierce skirmishes with their nearest assailants. Standing breast-high in the waves, and surrounded at intervals by total darkness, they were yet able to pour an occasional well-directed volley into the hostile ranks. The Zealanders, however, did, not assail them with fire-arms alone. They transfixed some with their fatal harpoons; they dragged others from the path with boathooks; they beat out the brains of others with heavy flails. Many were the mortal duels thus fought in the darkness, and, as it were, in the bottom of the sea; many were the deeds of audacity which no eye was to mark save those by whom they were achieved. Still, in spite of all impediments and losses, the Spaniards steadily advanced. If other arms proved less available, they were attached by the fierce taunts and invectives of their often invisible foes who reviled them as water-dogs, fetching and carrying for a master who despised them; as mercenaries who coined their blood for gold, and were employed by tyrants for the basest uses. If stung by these mocking voices, they turned in the darkness to chastise their unseen tormentors, they were certain to be trampled upon by their comrades, and to be pushed from their narrow pathway into the depths of the sea. Thus many perished.
The night wore on, and the adventurers still fought it out manfully, but very slowly, the main body of Spaniards, Germans, and Walloons, soon after daylight, reaching the opposite shore, having sustained considerable losses, but in perfect order. The pioneers were not so fortunate. The tide rose over them before they could effect their passage, and swept nearly every one away. The rearguard, under Peralta, not surprised, like the pioneers, in the middle of their passage, by the rising tide, but prevented, before it was too late; from advancing far beyond the shore from which they had departed were fortunately enabled to retrace their steps.
Don Osorio, at the head of the successful adventurers, now effected his landing upon Duiveland. Reposing themselves but for an instant after this unparalleled march through the water, of more than six hours, they took a slight refreshment, prayed to the Virgin Mary and to Saint James, and then prepared to meet their new enemies on land. Ten companies of French, Scotch, and English auxiliaries lay in Duiveland, under the command of Charles Van Boisot. Strange to relate, by an inexplicable accident, or by treason, that general was slain by his own soldiers, at the moment when the royal troops landed. The panic created by this event became intense, as the enemy rose suddenly, as it were, out of the depths of the ocean to attack them. They magnified the numbers of their assailants, and fled terror-stricken in every direction. Same swam to the Zealand vessels which lay in the neighbourhood; others took refuge in the forts which had been constructed on the island; but these were soon carried by the Spaniards, and the conquest of Duiveland was effected.
The enterprise was not yet completed, but the remainder was less difficult and not nearly so hazardous, for the creek which separated Duiveland from Schouwen was much narrower than the estuary which they had just traversed. It was less than a league in width, but so encumbered by rushes and briers that, although difficult to wade, it was not navigable for vessels of any kind. This part of the expedition was accomplished with equal resolution, so that, after a few hours' delay, the soldiers stood upon the much-coveted island of Schouwen. Five companies of states' troops, placed to oppose their landing, fled in the most cowardly manner at the first discharge of the Spanish muskets, and took refuge in the city of Zierickzee, which was soon afterwards beleaguered.
The troops has been disembarked upon Duiveland from the armada, which had made its way to the scene of action, after having received, by signal, information that the expedition through the water had been successful. Brouwershaven, on the northern side of Schouwen, was immediately reduced, but Bommenede resisted till the 25th of October, when it was at last carried by assault, and delivered over to fire and sword. Of the whole population and garrison not twenty were left alive. Siege was then laid to Zierickzee, and Colonel Mondragon was left in charge of the operations. Requesens himself came to Schouwen to give directions concerning this important enterprise.
Chiapin Vitelli also came thither in the middle of the winter, and was so much injured by a fall from his litter, while making the tour of the island, that he died on shipboard during his return to Antwerp. This officer had gained his laurels upon more than one occasion, his conduct in the important action near Mons, in which the Huguenot force under Genlis was defeated, having been particularly creditable. He was of a distinguished Umbrian family, and had passed his life in camps, few of the generals who had accompanied Alva to the Netherlands being better known or more odious to the inhabitants. He was equally distinguished for his courage, his cruelty, and his corpulence. The last characteristic was so remarkable that he was almost monstrous in his personal appearance. His protuberant stomach was always supported in a bandage suspended from his neck, yet in spite of this enormous impediment, he was personally active on the battle-field, and performed more service, not only as a commander but as a subaltern, than many a younger and lighter man.
