From this time the war enters on its fifth stage. Wallenstein did little more fighting. He withdrew his troops into Bohemia, and it is hard to say what purposes simmered in his dark and inscrutable brain. He certainly was no longer loyal to the Emperor; probably the Emperor plotted against him. Wallenstein seems to have contemplated making himself king of an independent Bohemian kingdom. At any rate, he broke openly with his sovereign, and at a great banquet persuaded his leading officers to sign an oath that they would stand by him in whatever he did. Some of the more timid among them warned the Emperor, and with his approval formed a trap for Wallenstein. The general's chief lieutenants were suddenly set upon and slain; then the murderers rushed to Wallenstein's own apartments. Hearing them coming, he stood up dauntlessly, threw wide his arms to their blows, and died as silent and mysterious as he had lived. His slayers were richly rewarded by Ferdinand. All Germany was weary of the war. The contending parties had fought each other to a standstill; and, had Germany alone been concerned, peace would certainly have followed. But the Swedes, abandoning Gustavus' higher policy, continued the war for what increase of territory they could get; and France helped herself to what German cities she could in Alsace and Lorraine. So the war went on, the German princes taking sides now with this one, now the other, and nobody apparently ever thinking of the poor peasantry. The spirit of the brutal soldiery grew ever more atrocious. Their captives were tortured to death for punishment or for ransom, or, it is to be feared, for the mere amusement of the bestial captors. The open country became everywhere a wilderness. The soldiers themselves began starving in the dismal desert. The Emperor, Ferdinand II, the cause of all this destruction, died in 1637, and was succeeded by his son, Ferdinand III (1637-1657). The war still continued, though in a feeble, listless way, with no decisive victories on either side, until the peace of Westphalia, in 1648. This peace placed Protestants and Catholics on an equal footing of toleration throughout the empire. It gave Sweden what territory she wanted in the north, and France what she asked toward the Rhine. Switzerland and Holland were acknowledged as independent lands. The importance of the smaller princes was increased, they, too, becoming practically independent, and the power of the emperors was all but destroyed. From this time the importance of the Hapsburgs rested solely on their personal possessions in Austria, Hungary, and Bohemia. The title of emperor remained little better than a name.
