“You must know,” Colonel Munro began, “that some twenty years ago the Protestant princes of Germany formed a league for mutual protection and support, which they called the Protestant Union; and a year later the Catholics, on their side, constituted what they called the Holy League. At that time the condition of the Protestants was not unbearable. In Bohemia, where they constituted two-thirds of the population, Rudolph II, and after him Mathias, gave conditions of religious freedom. “Gradually, however, the Catholic party about the emperor gained the upper hand; then various acts in breach of the conditions granted to the Protestants were committed, and public spirit on both sides became much embittered. On the 23d of May, 1618, the Estates of Bohemia met at Prague, and the Protestant nobles, headed by Count Thurn, came there armed, and demanded from the Imperial councillors an account of the high handed proceedings. A violent quarrel ensued, and finally the Protestant deputies seized the councillors Martinitz and Slavata, and their secretary, and hurled them from the window into the dry ditch, fifty feet below. Fortunately for the councillors the ditch contained a quantity of light rubbish, and they and their secretary escaped without serious damage. The incident, however, was the commencement of war. Bohemia was almost independent of Austria, administering its own internal affairs. The Estates invested Count Thurn with the command of the army. The Protestant Union supported Bohemia in its action. Mathias, who was himself a tolerant and well meaning man, tried to allay the storm; but, failing to do so, marched an army into Bohemia. “Had Mathias lived matters would probably have arranged themselves, but he died the following spring, and was succeeded by Ferdinand II. Ferdinand is one of the most bigoted Catholics living, and is at the same time a bold and resolute man; and he had taken a solemn vow at the shrine of Loretto that, if ever he came to the throne, he would re-establish Catholicism throughout his dominions. Both parties prepared for the strife; the Bohemians renounced their allegiance to him and nominated the Elector Palatine Frederick V, the husband of our Scotch princess, their king. “The first blow was struck at Zablati. There a Union army, led by Mansfeldt, was defeated by the Imperial general Bucquoi. A few days later, however, Count Thurn, marching through Moravia and Upper Austria, laid siege to Vienna. Ferdinand's own subjects were estranged from him, and the cry of the Protestant army, 'Equal rights for all Christian churches,' was approved by the whole population--for even in Austria itself there were a very large number of Protestants. Ferdinand had but a few soldiers, the population of the city were hostile, and had Thurn only entered the town he could have seized the emperor without any resistance.
