Meanwhile Sigismund, the emperor, was slowly gathering his forces to invade the rebellious land. The reign of cruelty continued, each side treating its prisoners barbarously. The Imperialists branded theirs with a cup, the Hussites theirs with a cross, on their foreheads. The citizens of Breslau joined those of Prague, and emulated them by flinging their councillors out of the town-house windows. In return the German miners of Kuttenberg threw sixteen hundred Hussites down the mines. Such is religious war, the very climax of cruelty.
In June, 1420, the threatened invasion came. Sigismund led an army, one hundred thousand strong, into the revolted land, fulminating vengeance as he marched. He reached Prague and entered the castle of Wisherad, which commanded it. Ziska fortified the mountain of Witlow (now called Ziskaberg), which also commanded the city. Sigismund, finding that he had been outgeneralled, and that his opponent held the controlling position, waited and temporized, amusing himself meanwhile by assuming the crown of Bohemia, and sowing dissension in his army by paying the Slavonian and Hungarian troops with the jewels taken from the royal palaces and the churches, while leaving the Germans unpaid. The Germans, furious, marched away. The emperor was obliged to follow. The ostentatious invasion was at an end, and scarcely a blow had been struck.
But Sigismund had no sooner gone than trouble arose in Prague. The citizens, the nobility, and Ziska's followers were all at odds. The Taborites—those strict republicans and religious reformers who had made Mount Tabor their head-quarters—were in power, and ruled the city with a rod of iron, destroying all the remaining splendor of the churches and sternly prohibiting every display of ostentation by the people. Death was named as the punishment for such venial faults as dancing, gambling, or the wearing of rich attire. The wine-cellars were rigidly closed. Church property was declared public property, and it looked as if private wealth would soon be similarly viewed. The peasants declared that it was their mission to exterminate sin from the earth.
This tyranny so incensed the nobles and citizens that they rose in self-defence, and Ziska, finding that Prague had grown too hot to hold him, deemed it prudent to lead his men away. Sigismund took immediate advantage of the opportunity by marching on Prague. But, quick as he was, there were others quicker. The more moderate section of the reformers, the so-called Horebites,—from Mount Horeb, another place of assemblage,—entered the city, led by Hussinez, Huss's former lord, and laid siege to the royal fortress, the Wisherad. Sigismund attempted to surprise him, but met with so severe a repulse that he fled into Hungary, and the Wisherad was forced to capitulate, this ancient palace and its church, both splendid works of art, being destroyed. Step by step the art and splendor of Bohemia were vanishing in this despotic struggle between heresy and the papacy.
As the war went on, Ziska, its controlling spirit, grew steadily more abhorrent of privilege and distinction, more bitterly fanatical. The ancient church, royalty, nobility, all excited his wrath. He was republican, socialist, almost anarchist in his views. His idea of perfection lay in a fraternity composed of the children of God, while he trusted to the strokes of the iron flail to bear down all opposition to his theory of society. The city of Prachaticz treated him with mockery, and was burnt to the ground, with all its inhabitants. The Bishop of Nicopolis fell into his hands, and was flung into the river. As time went on, his war of extermination against sinners—that is, all who refused to join his banner—grew more cruel and unrelenting. Each city that resisted was stormed and ruined, its inhabitants slaughtered, its priests burned. Hussite virtue had degenerated into tyranny of the worst type. Yet, while thus fanatical himself, Ziska would not permit his followers to indulge in insane excesses of religious zeal. A party arose which claimed that the millennium was at hand, and that it was their duty to anticipate the coming of the innocence of Paradise, by going naked, like Adam and Eve. These Adamites committed the maddest excesses, but found a stern enemy in Ziska, who put them down with an unsparing hand.
In 1421 Sigismund again roused himself to activity, incensed by the Hussite defiance of his authority. He incited the Silesians to invade Bohemia, and an army of twenty thousand poured into the land, killing all before them,—men, women, and children. Yet such was the terror that the very name of Ziska now excited, that the mere rumor of his approach sent these invaders flying across the borders.
But, in the midst of his career of triumph, an accident came to the Bohemian leader which would have incapacitated any less resolute man from military activity. During the siege of the castle of Raby a splinter struck his one useful eye and completely deprived him of sight. It did not deprive him of power and energy. Most men, under such circumstances, would have retired from army leadership, but John Ziska was not of that calibre. He knew Bohemia so thoroughly that the whole land lay accurately mapped out in his mind. He continued to lead his army, to marshal his men in battle array, to command them in the field and the siege, despite his blindness, always riding in a carriage, close to the great standard, and keeping in immediate touch with all the movements of the war.
Blind as he was, he increased rather than diminished the severity of his discipline, and insisted on rigid obedience to his commands. As an instance of this we are told that, on one occasion, having compelled his troops to march day and night, as was his custom, they murmured and said,—
"Day and night are the same to you, as you cannot see; but they are not the same to us."
"How!" he cried. "You cannot see! Well, set fire to a couple of villages."
