Even after this great battle he continued to preserve perfect discipline; every morning public prayer was offered to God, and Gustavus, with bared head stood before his victorious army leading them in a hymn of thanksgiving. What an object-lesson in godliness it was alike to the pious and the impious, not alone for that age, but for all time to come. The defeat of the Imperialists at Breitenfield settled the fate of the Edict of Restitution. At Vienna pious Catholics wondered "if God had indeed turned Lutheran." At Halle, Gustavus divided his army. He sent the Elector of Saxony into Bohemia, which was most anxious to shake off the Imperial yoke. The King of Sweden may have remembered that Bohemia was Ferdinand's crown lands and the Elector of Saxony would by that act forever exclude himself from Ferdinand's favor and be most fully committed to the perpetual alliance with Sweden. Gustavus himself undertook to march over all western Germany and to crush out the Catholic League in its different centers. Even the Catholics who had been so badly treated by Tilly's army, seeing the good conduct of the Swedish troops, came out to meet Gustavus and greeted him as the liberator of the country. His march through Thuringia and Franconia to the Main and the Rhine reads like a triumphal procession. The Duke of Saxe-Weimar now joined forces with Gustavus. He proved to be a skillful general and was useful in many ways, especially because of his familiarity with the country. As Gustavus approached Wurzburg the Catholic bishop of that city, so noted for his persecution of Protestants, fled and left his people to the mercy of the invaders. The city surrendered without any resistance. The king considered that as the country had been abandoned by its rulers the sovereignty became his, so he appointed a cabinet, one-half of whose members were Protestants. He restored to the Protestants their churches and encouraged the Catholics to attend their own churches, and to put them in repair. Only those who refused to submit were severely dealt with. He was really the first prince who understood religious toleration. In every place he claimed that as God's dealing is personal to each individual, each person should have liberty of conscience. On one occasion when a Catholic town had been captured, his officers suggested that here he could revenge Magdeburg. The king answered, "I have come to break the chains of slavery and not to forge new ones. Let them live as they have done hitherto."
