In 1614 Komenský returned to Moravia, and was ordained a minister of the Unity in 1616, as soon as he had attained the necessary age. He was first sent to the small town of Fulneck in Moravia, where he married and spent the happiest and almost the only tranquil years of his life. It was not his destiny to continue long undisturbed in the pursuit of his religious duties, and of the studies to which he was already devoted. The events of the Bohemian war cast their shadow even over the peaceful community of Fulneck. Rumours of the events of the war between Bohemia and Austria occasionally reached the brethren. As Komenský wrote: "Lightning shines before it strikes, and by its light we could see the glooming, gathering clouds of persecution," After the battle of the White Mountain the brethren, as the most decided opponents of Rome, were naturally the first to suffer. Detachments of troops, generally Spaniards, who were chosen for this purpose because of their greater bigotry and ferocity, scoured Bohemia and Moravia in every direction, burning down the settlements of the brethren, and killing or driving from the country the members of the communities. In 1621 a Spanish detachment attacked Fulneck and burnt down the town, forcing the brethren to fly for their lives. The MSS. and library of Komenský were here for the first, but unhappily not for the last time burnt and destroyed. Komenský himself managed to escape and sought refuge in Bohemia at Brandeis-on-the-Adler, which has already been mentioned as one of the centres of the Unity. The little town then belonged to Charles, Lord of Žerotin.[99] Though during his whole life a devoted member of the Unity, Žerotin had remained faithful to the House of Austria during the war that had just ended, and had even been menaced by the Moravian nobles, who had adopted the cause of Frederick of the Palatinate. In acknowledgment of his services, he was not by the Catholics included in the general decree of exile, and the Austrian authorities at first even overlooked the fact that many members of Žerotin's Church, among whom was Komenský, sought refuge at Brandeis. Komenský's intense literary activity, that had already begun at Fulneck, continued at Brandeis. There, besides minor works, the _Labyrinth of the World_ was written, though the book was afterwards enlarged.
