Then Alva came out from Brussels to wreak a fearful vengeance on Mons, Mechlin, Tergoes, Naarden, Haarlem, and Zutphen. The terms of the capitulation of Mons were violated. Mechlin was plundered and set on fire by the Spanish troops. The Spanish commander sent against Zutphen had orders to burn every house, and to slay men, women, and children. Haarlem was invested, resisted desperately, and then capitulated on promise of lenient treatment. When the Spaniards entered they butchered in cold blood all the Dutch soldiers and some hundreds of the citizens; and, tying the bodies two and two together, they cast them into the Haarlem lake. It seemed as if the Papists had determined to exterminate the Protestants when they found that they could not convert them.
Some towns, however, held out. Don Frederick, the son of Alva and the butcher of Haarlem, was beaten back from the little town of Alkmaar. The _Sea-Beggars_ met the Spanish fleet sent to crush them, sank or scattered the ships, and took the Admiral prisoner. The nation of fishermen and shopkeepers, once the scorn of Spain and of Europe for their patient endurance of indignities, were seen at last to be a race of heroes, determined never again to endure the yoke of the Spaniard. Alva had soon to face a soldiery mutinous for want of pay, and to see all his sea approaches in the hands of Dutch sailors, whom the strongest fleets of Spain could not subdue. The iron pitiless man at last acknowledged that he was beaten, and demanded his recall. He left Brussels on Dec. 18th, 1573, and did not again see the land he had deluged with blood during a space of six years. Like all tyrants, he had great faith in his system, even when it had broken in his hand. Had he been a little more severe, added a few more drops to the sea of blood he had spilled, all would have gone well. The only advice he could give to his successor was, to burn down every town he could not garrison with Spanish troops.
The new Spanish Regent was Don Louis Requesens-y-Zuniga, a member of the higher nobility of Spain, and a Grand Commander of the Knights of Malta. He was high-minded, and of a generous disposition. Had he been sent to the Netherlands ten years sooner, and allowed to act with a free hand, the history of the Netherlands might have been different. His earlier efforts at government were marked by attempts to negotiate, and he was at pains to give Philip his reasons for his conduct.
