Even Ferdinand could not be blind to the difficulties which were accumulating upon him, and to the precarious tenure of his power. He saw the necessity of persevering in the attempt at conciliation which he had so reluctantly commenced. And yet, with strange infatuation, he proposed an accommodation in a manner which was deemed insulting, and which tended only to exasperate. The very day of his accession to the throne, he sent a commission to Prague, to propose a truce; but, instead of conferring with the Protestant leaders, he seemed to treat them with intentional contempt, by addressing his proposal to that very council of regency which had become so obnoxious. The Protestants, justly regarding this as an indication of the implacable state of his mind, and conscious that the proposed truce would only enable him more effectually to rally his forces, made no reply whatever to his proposals. Ferdinand, perceiving that he had made a great mistake, and that he had not rightly appreciated the spirit of his foes, humbled himself a little more, and made still another attempt at conciliation. But the Protestants had now resolved that Ferdinand should never be King of Bohemia. It had become an established tenet of the Catholic church that it is not necessary to keep faith with heretics. Whatever solemn promises Ferdinand might make, the pope would absolve him from all sin in violating them. Count Thurn, with sixteen thousand men, marched into Moravia. The people rose simultaneously to greet him. He entered Brunn, the capital, in triumph. The revolution was immediate and entire. They abolished the Austrian government, established the Protestant worship, and organized a new government similar to that which they had instituted in Bohemia. Crossing the frontier, Count Thurn boldly entered Austria and, meeting no foe capable of retarding his steps, he pushed vigorously on even to the very gates of Vienna. As he had no heavy artillery capable of battering down the walls, and as he knew that he had many partisans within the walls of the city, he took possession of the suburbs, blockaded the town, and waited for the slow operation of a siege, hoping thus to be able to take the capital and the person of the sovereign without bloodshed. Ferdinand had brought such trouble upon the country, that he was now almost as unpopular with the Catholics as with the Protestants, and all his appeals to them for aid were of but little avail. The sudden approach of Count Thurn had amazed and discomfited him, and he knew not in what direction to look for aid. Cooped up in his capital, he could hold no communication with foreign powers, and his own subjects manifested no disposition to come to his rescue. The evidences of popular discontent, even in the city, were every hour becoming more manifest, and the unhappy sovereign was in hourly expectation of an insurrection in the streets.
