Then a first success came to William's cause like a faint ray of sunlight through heavy clouds, for the Beggars of the Sea captured the fortified town of Brill. And almost immediately after, encouraged by this initial success, the whole of the Netherlands which had been groaning under the Spanish rule rose in rebellion and claimed as their rightful ruler the Prince of Orange. Almost in a night the cities rose and cast off their Spanish yoke, and all through the Low Countries the flag of the Prince of Orange was uplifted.
Alva sent his troops to lay siege to the towns and recapture them, and there followed one of the most terrible periods of warfare that the world has ever known—certainly the most terrible that ever engulfed Belgium until the World War of our own day.
And now for the first time since his former defeat, the Prince of Orange was able to raise troops to fight once more against the Spaniards. He sent repeated appeals to the cities of the Low Countries, and prepared an army of some twenty thousand German mercenaries that was to be further strengthened by a French force under the French Admiral Coligny. William counted on Coligny's aid to defeat Alva, for Coligny was an ardent Protestant and had many men at his command.
But there befell another check to William's fortunes, and one that was almost fatal to his plans, for under the wicked Catherine de Medici the French Catholics in two days massacred almost every Protestant in France in a slaughter that was called the Massacre of St. Bartholomew. Admiral Coligny was among the victims, and all hope of support from that quarter was at an end.
Louis, the brother of William, was being besieged by the Duke of Alva in the city of Mons, and William marched to the relief of the town. He did not strike promptly enough, however, and was routed by a strategem on the part of the Spaniards. In the night a considerable force of the Spanish soldiers stole up to William's camp and fell upon his army, taking it completely by surprise. William himself barely escaped with his life, being awakened by a pet dog in the nick of time, and when the Spaniards were almost in his tent. Leaping to his horse, he galloped madly from the burning camp and escaped, but his army was cut to pieces. Then Alva continued the siege of Mons until Louis had to surrender. The Spaniards, however, for some strange reason allowed Louis to evacuate the town without interference and Louis fled to Dillenburg in Germany, the home of the Nassau family. But in spite of this new defeat and disappointment, the Lowland cities continued their resistance, and nowhere was this stronger than in the province of Holland.
The sieges that followed were among the most terrible in history for the beleaguered towns knew well they could expect no mercy if they were conquered, and held out to the last breath. Their inhabitants ate horses, dogs, old shoes—anything to fill their stomachs and stay the inroads of starvation. Plague broke out among them and in the Spanish forces as well. When the Spaniards captured a town they left not one stone upon another, and the burghers who had opposed them were massacred to a man.
But the Duke of Alva was growing old and suffering from ill health. The universal hatred in which he was held weighed on his spirit. He had written several times asking his recall from the Netherlands, and at last King Philip consented to his request and sent out a Governor named Requesens to take his place. All the Netherlands went wild with joy when the news spread that Alva was leaving and bells were rung and bonfires lit as for some national holiday.
In the meantime William had made his headquarters in the province of Holland and was conducting the war against the Spaniards from that point. The Spaniards were besieging the city of Leyden, which it was necessary for them to capture, but the Netherlanders cut the dykes that restrained the ocean and let the sea sweep over the land, for Leyden was reduced to starvation, and every day people were dying by hundreds within its walls. The rescuers sailed up to the town in ships as the Spaniards fled, bringing bread to the famished people.
William was now the ruler of Holland and had triumphed over the Spaniards. The war dragged after these terrible sieges and both sides would gladly have seen it ended; but the Lowlanders were in no temper to accept half measures. And in the Union of Utrecht, in which a number of the Lowland provinces united against Philip, an important step was taken toward throwing off the Spanish yoke.
William's life was in great danger, for King Philip had offered a reward of twenty-five thousand crowns in gold to any assassin who should strike him down. And although he was under fifty, he appeared like an old man, so great were the troubles with which he had been beset in the course of his life. He was the constant target for the bullet or the dagger of the assassin, and many dogged his tracks as a result of the Spanish proclamation against him.
