The emperor was in his bed as he received this insulting announcement of a still more insulting outrage. For a moment he was speechless with rage. But he was old, sick and powerless. This act revealed to him that the scepter had fallen from his hands. In a paroxysm of excitement, to prevent himself from speaking he thrust the bed-clothes into his mouth, nearly suffocating himself. Resistance was in vain. He feared that should he manifest any, he also might be torn from his palace, a captive, to share the prison of the cardinal. In sullen indignation he submitted to the outrage.
Ferdinand and Maximilian now pursued their energetic measures of hostility unopposed. They immediately put the army in motion to invade Bohemia, and boasted that the Protestants should soon be punished with severity which would teach them a lesson they would never forget. But the Protestants were on the alert. Every town in the kingdom had joined in the confederacy, and in a few weeks Count Thurn found himself at the head of ten thousand men inspired with the most determined spirit. The Silesians and Lusatians marched to help them, and the Protestant league of Germany sent them timely supplies. The troops of Ferdinand found opponents in every pass and in every defile, and in their endeavor to force their way through the fastnesses of the mountains, were frequently driven back with great loss. At length the troops of Ferdinand, defeated at every point, were compelled to retreat in shame back to Austria, leaving all Bohemia in the hands of the Protestants.
Ferdinand was now in trouble and disgrace. His plans had signally failed. The Protestants all over Germany were in arms, and their spirits roused to the highest pitch; many of the moderate Catholics refused to march against them, declaring that the Protestants were right in resisting such oppression. They feared Ferdinand, and were apprehensive that his despotic temper, commencing with religious intolerance, would terminate in civil tyranny. It was evident to all that the Protestants could not be put down by force of arms, and even Ferdinand was so intensely humiliated that he was constrained to assent to the proposal which Matthias made to refer their difficulty to arbitration. Four princes were selected as the referees—the Electors of Mentz, Bavaria, Saxony and Palatine. They were to meet at Egra the 14th of April, 1619.
