To these manifold evils was now added one more terrible, in the appearance of the plague, which broke out at Ghent in the month of October, and devastated a great part of the Netherlands; not, however, with that violence with which it rages in more southern climates.

Requesens, overwhelmed by difficulties, yet exerted himself to the utmost to put the best face on the affairs of government. His chief care was to appease the mutinous soldiery: he even caused his plate to be melted, and freely gave the produce toward the payment of their arrears. The patriots, well informed of this state of things, labored to turn it to their best advantage. They opened the campaign in the province of Guelders, where Louis of Nassau, with his younger brother Henry, and the prince Palatine, son of the elector Frederick III., appeared at the head of eleven thousand men; the Prince of Orange prepared to join him with an equal number; but Requesens promptly despatched Sanchez d'Avila to prevent this junction. The Spanish commander quickly passed the Meuse near Nimeguen; and on the 14th of April he forced Count Louis to a battle, on the great plain called Mookerheyde, close to the village of Mook. The royalists attacked with their usual valor; and, after two hours of hard fighting, the confederates were totally defeated. The three gallant princes were among the slain, and their bodies were never afterward discovered. It has been stated, on doubtful authority, that Louis of Nassau, after having lain some time among the heaps of dead, dragged himself to the side of the river Meuse, and while washing his wounds was inhumanly murdered by some straggling peasants, to whom he was unknown. The unfortunate fate of this enterprising prince was a severe blow to the patriot cause, and a cruel affliction to the Prince of Orange. He had now already lost three brothers in the war; and remained alone, to revenge their fate and sustain the cause for which they had perished.

D'Avila soon found his victory to be as fruitless as it was brilliant. The ruffian troops, by whom it was gained, became immediately self-disbanded; threw off all authority; hastened to possess themselves of Antwerp; and threatened to proceed to the most horrible extremities if their pay was longer withheld. The citizens succeeded with difficulty in appeasing them, by the sacrifice of some money in part payment of their claims. Requesens took advantage of their temporary calm, and despatched them promptly to take part in the siege of Leyden.

This siege formed another of those numerous instances which became so memorable from the mixture of heroism and horror. Jean Vanderdoes, known in literature by the name of Dousa, and celebrated for his Latin poems, commanded the place. Valdez, who conducted the siege, urged Dousa to surrender; when the latter replied, in the name of the inhabitants, "that when provisions failed them, they would devour their left hands, reserving the right to defend their liberty." A party of the inhabitants, driven to disobedience and revolt by the excess of misery to which they were shortly reduced, attempted to force the burgomaster, Vanderwerf, to supply them with bread, or yield up the place. But he sternly made the celebrated answer, which, cannot be remembered without shuddering—"Bread I have none; but if my death can afford you relief, tear my body in pieces, and let those who are most hungry devour it!"

But in this extremity relief at last was afforded by the decisive measures of the Prince of Orange, who ordered all the neighboring dikes to be opened and the sluices raised, thus sweeping away the besiegers on the waves of the ocean: the inhabitants of Leyden were apprised of this intention by means of letters intrusted to the safe carriage of pigeons trained for the purpose. The inundation was no sooner effected than hundreds of flat-bottomed boats brought abundance of supplies to the half-famished town; while a violent storm carried the sea across the country for twenty leagues around, and destroyed the Spanish camp, with above one thousand soldiers, who were overtaken by the flood. This deliverance took place on the 3d of October, on which day it is still annually celebrated by the descendants of the grateful citizens.

It was now for the first time that Spain would consent to listen to advice or mediation, which had for its object the termination of this frightful war. The emperor Maximilian II. renewed at this epoch his efforts with Philip; and under such favorable auspices conferences commenced at Breda, where the counts Swartzenberg and Hohenloe, brothers-in-law of the Prince of Orange, met, on the part of the emperor, the deputies from the king of Spain and the patriots; and hopes of a complete pacification were generally entertained. But three months of deliberation proved their fallacy. The patriots demanded toleration for the reformed religion. The king's deputies obstinately refused it. The congress was therefore broken up; and both oppressors and oppressed resumed their arms with increased vigor and tenfold desperation.

Requesens had long fixed his eyes on Zealand as the scene of an expedition by which he hoped to repair the failure before Leyden; and he caused an attempt to be made on the town of Zuriczee, in the island of Scauwen, which merits record as one of the boldest and most original enterprises of the war.

The little islands of Zealand are separated from each other by narrow branches of the sea, which are fordable at low water; and it was by such a passage, two leagues in breadth, and till then untried, that the Spanish detachment of one thousand seven hundred and fifty men, under Ulloa and other veteran captains, advanced to their exploit in the midst of dangers greatly increased by a night of total darkness. Each man carried round his neck two pounds of gunpowder, with a sufficient supply of biscuit for two days; and holding their swords and muskets high over their heads, they boldly waded forward, three abreast, in some places up to their shoulders in water. The alarm was soon given; and a shower of balls was poured upon the gallant band, from upward of forty boats which the Zealanders sent rapidly toward the spot. The only light afforded to either party was from the flashes of their guns; and while the adventurers advanced with undaunted firmness, their equally daring assailants, jumping from their boats into the water, attacked them with oars and hooked handspikes, by which many of the Spaniards were destroyed. The rearguard, in this extremity, cut off from their companions, was obliged to retreat; but the rest, after a considerable loss, at length reached the land, and thus gained possession of the island, on the night of the 28th of September, 1575.

Requesens quickly afterward repaired to the scene of this gallant exploit, and commenced the siege of Zuriczee, which he did not live to see completed. After having passed the winter months in preparation for the success of this object which he had so much at heart, he was recalled to Brussels by accounts of new mutinies in the Spanish cavalry; and the very evening before he reached the city he was attacked by a violent fever, which carried him off five days afterward, on the 5th of March, 1516.

The suddenness of Requesen's illness had not allowed time for even the nomination of a successor, to which he was authorized by letters patent from the king. It is believed that his intention was to appoint Count Mansfield to the command of the army, and De Berlaimont to the administration of civil affairs. The government, however, now devolved entirely into the hands of the council of state, which was at that period composed of nine members. The principal of these was Philip de Croi, duke of Arschot; the other leading members were Viglius, Counts Mansfield and Berlaimont; and the council was degraded by numbering, among the rest, Debris and De Roda, two of the notorious Spaniards who had formed part of the Council of Blood.
