This triumph was followed by an act of power and defiance on Alva's part sometimes compared to the execution of Louis XVI by the French Republicans. Hitherto the sufferers from his reign of blood had not in any case been men of the highest rank. The first execution of nobles took place at Brussels on June 1, that of the captured Villiers followed on June 2, and that of Egmont and Horn on June 5. Orange himself now took the field with 25,000 troops, a motley aggregate of French, Flemish, and Walloon Huguenots and of German mercenaries. But he had no genius for war to oppose to the veterans of Alva. Continually harassed by the Spaniards he was kept in fear for his communications, dared not risk a general engagement and was humiliated by seeing his retreat, in November, turned into a rout. [Sidenote: July 16, 1570] Finding that severity did not pacify the provinces, Alva issued a proclamation that on the face of it was a general amnesty with pardon for all who submitted. But he excepted by name several hundred emigrants, all the Protestant clergy, all who had helped them, all iconoclasts, all who had signed petitions for religious liberty, and all who had rebelled. As these exceptions included the greater portion of those who stood in need of pardon the measure proved illusory as a means of reconciliation. Coupled with it were other measures, including the prohibition to subjects to attend foreign universities, intended to put a check on free trade in ideas. [Sidenote: Taxation] Alva's difficulties and the miseries of the unhappy land entrusted to his tender mercies were increased by want of money. Notwithstanding the privilege of {260} granting their own taxes the States General were summoned [Sidenote: March 21, 1569] and forced to accept new imposts of one per cent. on all property real and personal, ten per cent. on the sale of all movable goods and five per cent. on the sale of real estate. These were Spanish taxes, exorbitant in any case but absolutely ruinous to a commercial people. A terrible financial panic followed. Houses at Antwerp that had rented for 300 gulden could now be had for 50 gulden. Imports fell off to such an extent that at this port they yielded but 14,000 gulden per annum instead of 80,000 as formerly. The harbor was filled with empty boats; the market drugged with goods of all sorts that no one would buy. [Sidenote: Beggars of the Sea]
