On March 20, before the next campaign opened, Matthias died. Ferdinand's renewed promises to respect the Royal Charter—made doubtless under the reservation of putting his own interpretation upon the disputed points—were rejected with scorn by the Directors. The sword was to decide the quarrel. With the money received from the Dutch, and with aid in money and munitions of war from Heidelberg, Thurn and Mansfeld were enabled to take the field. The latter remained to watch Bucquoi, whilst the former undertook to win the other territories, which had hitherto submitted to Matthias, and had stood aloof from the movement in Bohemia. Without much difficulty he succeeded in revolutionizing Moravia, and he arrived on June 5 under the walls of Vienna. Within was Ferdinand himself, with a petty garrison of 300 men, and as many volunteers as he could attach to his cause. Thurn hoped that his partisans inside the cities would open the gates to admit him. But he lost time in negotiations with the Austrian nobility. The estates of the two territories of Upper and Lower Austria were to a great extent Protestant, and they had refused to do homage to Ferdinand on the death of Matthias. The Lower Austrians now sent a deputation to Vienna to demand permission to form a confederation with the Bohemians, on terms which would practically have converted the whole country, from the Styrian frontier to the borders of Silesia, into a federal aristocratic republic.

§ 3. Ferdinand resists the demands of the Lower Austrian Estates.

In Ferdinand they had to do with a man who was not to be overawed by personal danger. He knew well that by yielding he would be giving a legal basis to a system which he regarded as opposed to all law, human and divine. Throwing himself before the crucifix, he found strength for the conflict into which he entered on behalf of his family, his church, and, as he firmly believed, of his country and his God—strength none the less real because the figure on the cross did not, as men not long afterwards came fondly to believe, bow its head towards the suppliant, or utter the consoling words: 'Ferdinand, I will not forsake thee.'

§ 4. Rescue arrives.

To a deputation from the Austrian Estates he was firm and unbending. They might threaten as they pleased, but the confederation with Bohemia he would not sign. Rougher and rougher grew the menaces addressed to him. Some one, it is said, talked of dethroning him and of educating his children in the Protestant religion. Suddenly the blare of a trumpet was heard in the court below. A regiment of horses had slipped in through a gate unguarded by Thurn, and had hurried to Ferdinand's defence. The deputation, lately so imperious, slunk away, glad enough to escape punishment.

§ 5. The siege raised.

Little would so slight a reinforcement have availed if Thurn had been capable of assaulting the city. But, unprovided with stores of food or siege munitions, he had counted on treason within. Disappointed of his prey, he returned to Bohemia, to find that Bucquoi had broken out of Budweis, and had inflicted a serious defeat on Mansfeld.

§ 6. The Imperial election.

Ferdinand did not linger at Vienna to dispute his rights with his Austrian subjects. The election of a new Emperor was to take place at Frankfort, and it was of importance to him to be on the spot. To the German Protestants the transfer of the Imperial crown to his head could not be a matter of indifference. If he succeeded, as there seemed every probability of his succeeding, in re-establishing his authority over Bohemia, he would weigh with a far heavier weight than Matthias upon the disputes by which Germany was distracted. The Elector Palatine and his councillors had a thousand schemes for getting rid of him, without fixing upon any. John George of Saxony, in 1619 as in 1612, had a definite plan to propose. Ferdinand, he said, was not in possession of Bohemia, and could not, therefore, vote as King of Bohemia at the election. The election must, therefore, be postponed till the Bohemian question had been settled by mediation. If only the three Protestant electors could have been brought to agree to this course, an immediate choice of Ferdinand would have been impossible.
