Philip now ordered ten thousand Spanish veterans, led by Alva, to march from Italy to the Netherlands. Making their way through the Free County of Burgundy and Lorraine they entered Brussels on August 9, 1567. [Sidenote: Alva 1508-83] Ferdinand Alvarez de Toledo, Duke of Alva, had won experience and reputation as a soldier in the German wars. Though self-controlled and courtly in manner, his passionate patriotism and bigotry made him a fit instrument to execute Philip's orders to make the Netherlands Spanish and Catholic. He began with no uncertain hand, building forts at Antwerp and quartering his troops at Brussels where their foreign manners and Roman piety gave offence to the citizens. On September 9 he arrested the counts of Egmont and Horn, next to Orange the chief leaders of the patriotic party. Setting up a tribunal, called the Council of {258} Troubles, to deal with cases of rebellion and heresy, he inaugurated a reign of terror. He himself spent seven hours a day in this court trying cases and signing death-warrants. Not only heretics were punished but also agitators and those who had advocated tolerance. Sincere Catholics, indeed, noted that the crime of heresy was generally the mere pretext for dealing with patriots and all those obnoxious to the government. [Sidenote: Executions] For the first time we have definite statistics of the numbers executed. For instance, on January 4, 1568, 48 persons were sentenced to death, on February 20, 37; on February 21, 71; on March 20, 55; and so on for day after day, week in and week out. On March 3 at the same hour throughout the whole land 1500 men were executed. The total number put to death during the six years of Alva's administration has been variously estimated at from 6,000 to 18,000. The lower number is probably nearer the truth, though not high enough. Emigration on a hitherto unknown scale within the next thirty or forty years carried 400,000 persons from the Netherlands. Thousands of others fled to the woods and became freebooters. The people as a whole were prostrated with terror. The prosperity of the land was ruined by the wholesale confiscations of goods. Alva boasted that by such means he had added to the revenues of his territories 500,000 ducats per annum. William of Orange retired to his estates at Dillenburg not to yield to the tyrant but to find a _point d'appui_ from which to fight. Wishing to avoid anything that might cause division among the people he kept the religious issue in the background and complained only of foreign tyranny. He tried to enlist the sympathies of the Emperor Maximilian II and to collect money and men. William's friend Villiers invaded the Burgundian State near Maastricht and Louis of Nassau marched with troops into Friesland. {259} [Sidenote: April, 1568] By this time Alva had increased his army by 10,000 German cavalry and both the rebel leaders were severely defeated.
